Based on the photographed panels and the listed two air conditioners, two furnaces, well equipment, pool equipment, two dryers, barn feeder, and electric shop heater, **32–38 kW is the more comfortable likely fit** if the goal is broad whole-house use rather than essentials-only backup. - **A 26 kW unit can still be practical** if EV charging, electric resistance heaters, electrically heated pool equipment, electric dryers, and selected other large loads are locked out or shed during an outage, and the air conditioners are staged so they do not start together. Check the fuel-specific output: for example, one current Generac “26 kW” model is rated at **24 kW on natural gas**, not the full nameplate number ([Generac 26 kW specifications](https://www.generac.com/residential-products/standby-generators/gaseous/standby-generator-26kw-7327/)). - **A true near-full-capacity match for a 200 A, 120/240 V service is approximately 48 kW** because 200 A × 240 V = 48 kVA. That does not automatically mean a 48 kW generator is required; a calculated load and automatic load management can justify a smaller unit. - **For a future 320/400 A service with a 200 A garage panel and EV charging, plan around a 48–60 kW managed generator**, with EV chargers and large resistance heaters normally disabled during generator operation. Attempting to back up the entire future service with every large load available could push the design toward **80–100 kW commercial-class equipment**, which is usually poor value for a residence. >[!important]- insight >The service upgrade and generator should be designed as one project even if they are installed at different times. Installing a 200 A transfer switch now without deciding how a later 320/400 A service will be divided could strand or complicate expensive equipment. ## What the current panel information suggests The garage appears to have a 200 A main, a 100 A feeder to the barn, and several other substantial 240 V loads. Separate 100 A pool and basement panels are also pictured. The photos do **not** establish whether all panels are downstream of one 200 A service, whether there are multiple service disconnects, or what the actual peak demand is. The likely high-demand or high-starting-current loads are: - Two air-conditioning compressors - Well pump and water-treatment equipment - Two dryers; their electrical demand depends on whether the heat source is electric or gas - Pool pump, sump pump, and pool furnace or heater; heating demand depends on its fuel type - Barn and shop loads, including the 220 V electric heater - Refrigerators, freezer, and ice maker - Any future EV chargers Because several of these loads cycle or are optional during an outage, adding all breaker ratings would substantially overstate the required generator size. The final design should use a dwelling load calculation, measured peak demand if available, motor-starting data, fuel type and pressure, and an agreed outage load-priority list. ## Generator sizing scenarios | Planning scenario | Generator class | What it is intended to support | Required load-management approach | | -------------------------------------------------------------- | --------------: | ------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | | Essentials plus normal comfort | 24–26 kW | Refrigeration, lights, receptacles, furnaces, well, controls, and usually one air conditioner at a time | Lock out EV charging, shop/barn electric heat, electrically heated pool equipment, and electric dryers; stage air conditioners | | Broad current whole-house use — **recommended quote target** | 32–38 kW | Most house loads, well, refrigeration, and more HVAC flexibility | Still shed EVs, resistance heaters, and possibly dryers or pool equipment during peaks | | Near-full present 200 A capability | About 48 kW | Approaches the 48 kVA ceiling of a 200 A, 240 V service | Verify motor-starting capability and fuel supply; selective shedding remains prudent | | Future 320/400 A service, EVs excluded during outages | 48–60 kW | House plus selected garage, barn, and pool loads | Automatically lock out EV chargers and large resistance heat; prioritize HVAC, well, and refrigeration | | Future service with nearly everything available simultaneously | About 80–100 kW | Attempts to cover the future service, multiple EVs, HVAC, and large electric loads together | Commercial engineering, larger transfer equipment, and major fuel-supply work; generally not recommended | Current residential products exist across these planning ranges: Generac publishes 32 kW and 38 kW Protector ratings and 48 kW single-phase output, while Kohler lists a 48 kW model at 200 A and 240 V ([Generac Protector specifications](https://www.generac.com/globalassets/products/residential/standby-generators/spec-sheets/22kw-27kw-32kw-38kw-protector-qs-standby-generator-specsheet.pdf), [Generac 48 kW specifications](https://www.generac.com/globalassets/products/residential/standby-generators/spec-sheets/xg03245-xg04045_hsb_specsheet.pdf), [Kohler 48 kW specifications](https://www.kohlerhomeenergy.rehlko.com/products/home-generators/48rclc)). These examples establish available size classes, not a brand recommendation. ## Recommended current configuration My preferred current design would be a **32–38 kW natural-gas or propane generator with a service-rated automatic transfer switch and automatic load management**. Ask the bidders to provide an alternate price for a 26 kW system using the same priorities so the cost-versus-convenience tradeoff is explicit. Suggested outage priorities: 1. **Always available:** furnaces and controls, well pump, sump pump, refrigerators/freezers, essential lighting and receptacles, internet, and safety systems. 2. **Managed and staged:** air conditioners, one dryer, pool pump, and other discretionary 240 V loads. 3. **Normally locked out:** EV charging, barn/shop electric resistance heater, electrically heated pool equipment, electric dryers, and other large nonessential loads. Generator load-management systems can actively shed large appliances instead of relying on memory; for example, Generac documents management of up to eight loads and specifically includes 240 V loads and central air conditioners ([Generac Smart Management Module manual](https://www.generac.com/globalassets/residential/dealers--installers/generac-installer-programs/solar--battery-installer-support/10000030493-rev-e-50a-smart-management-module-install--owners-manual.pdf)). Ask whether soft-start equipment is appropriate for each air conditioner. Reducing compressor starting demand may improve performance, but the generator dealer and HVAC contractor must confirm compatibility and use the actual compressor data. ## Future 320/400 A service and 200 A garage plan A practical future architecture is one **320/400 A residential service** divided into two major 200 A distribution paths: - **200 A house side:** house, basement mechanical equipment, and selected critical loads behind the generator transfer arrangement. - **200 A garage side:** garage, EV charging, shop loads, and possibly redistributed barn or pool feeders, subject to the electrician’s load calculation and site layout. NIPSCO currently publishes residential service standards for **100 A, 200 A, and 320/400 A** overhead and underground arrangements, so the larger service class is supported in principle, subject to NIPSCO engineering, available transformer capacity, local inspection, and the exact service route ([NIPSCO electric standards](https://www.nipsco.com/partner-with-us/builders-and-developers/gas-and-electric-standards), [NIPSCO underground 200 and 320/400 A standard](https://www.nipsco.com/docs/librariesprovider11/partner-with-us/builders-and-developers/electrical-standards/service-install-and-meter-equipment-approval/er19270.pdf?sfvrsn=4aa40351_0)). ### EV charging allowance A common full-speed residential Level 2 charger delivers 48 A at 240 V, or 11.5 kW, and uses a 60 A branch circuit. EV charging is a continuous load, so charger output and circuit size must be coordinated; ChargePoint documents the 48 A / 60 A pairing and the 125% circuit requirement ([ChargePoint Home Flex installation guide](https://docs.chargepoint.com/ref-docs-sec/content/pdfs/1-home/flex/flex-ig.pdf)). For two cars, choose deliberately between: - **Maximum independent charging:** two 60 A circuits can permit two 48 A chargers to draw up to 96 A, or about 23 kW, at the same time. - **Shared charging — recommended for most households:** install two compatible chargers with group or dynamic power management and set a shared garage limit. Tesla documents systems in which multiple Wall Connectors automatically distribute an allocated supply, reducing the need to size for every charger at full output simultaneously ([Tesla group power management](https://energylibrary.tesla.com/docs/Public/Charging/WallConnector/Gen3/Install/UniversalWC/en-us/GUID-A79F786F-4382-4E46-932C-F16E6D822779.html)). Even with a 200 A garage panel, EV chargers should normally receive a generator lockout signal or be placed outside the backed-up load path. Spending generator and fuel capacity to charge cars during an outage is rarely the best tradeoff when the same capacity can support HVAC, water, refrigeration, and lighting. ## Avoiding rework if the generator comes first If the generator is installed before the service upgrade, choose one of these architectures explicitly: 1. **Stable backed-up-load panel:** create a defined house backup panel that can remain behind the same transfer equipment after the future service upgrade. 2. **Future house-side transfer switch:** design the future 320/400 A service now so the generator and transfer switch will ultimately serve only the planned 200 A house side. 3. **Delay the final transfer equipment:** complete the service one-line design first, then purchase the generator and transfer equipment sized for that final topology. The second option is my recommendation: back up the future 200 A house side with a **48–60 kW managed generator only if broad future coverage is worth the cost**, while leaving EV charging and most garage resistance loads on the non-backed-up side. A smaller 32–38 kW generator may still remain sufficient if the house-side calculated outage load supports it. ## Information required before selecting equipment - Trace and document the one-line relationship among the garage, basement, pool, barn, meter, and all service disconnects. - Confirm the present utility service rating, conductor sizes, meter class, grounding and bonding arrangement, and available fault current. - Obtain at least 12 months of utility interval or peak-demand data if NIPSCO can provide it. - Record nameplate running current and locked-rotor or starting data for both air conditioners, the well pump, pool equipment, furnaces, dryers, and electric heaters. - Confirm whether the furnaces and pool furnace use gas or electricity for heat. - Decide which loads must run simultaneously during an outage and which may be delayed or locked out. - Have NIPSCO confirm the feasibility and cost of a 320/400 A service, including transformer, service-drop or lateral, trenching, meter equipment, and timing. - Require the generator contractor to provide the calculated running load, largest-step starting load, fuel demand at full output, transfer-switch topology, load-shed sequence, and written assumptions with the proposal. >[!warning] >This is a planning estimate, not an electrical load calculation or installation design. Generator, transfer-switch, service, grounding, fuel, and EV equipment must be sized and permitted by qualified contractors using the adopted electrical code, local requirements, manufacturer instructions, and NIPSCO approval. # Generac versus Kohler pricing and specifications ## Bottom line - **Current value option:** The comparable air-cooled packages are the **Generac 26 kW with 200 A transfer switch** and **Kohler 26 kW RCAL with transfer switch**. Estimated installed totals are approximately **$15,200–$21,200** and **$15,400–$21,400**, respectively. Their usable output is essentially identical, so local dealer quality, service response, and the proposed load-management design should decide between them. - **Current comfort option:** Compare the liquid-cooled **Generac 40 kW** with the **Kohler 38 kW**. Estimated installed totals are approximately **$35,900–$43,900** and **$34,900–$42,900**, respectively. Generac supplies 2 kW more output; Kohler publishes notably quiet operation and a 74 kVA motor-starting rating. - **Expanded-service sweet spot:** If the future generator serves only the planned 200 A house side and excludes EV charging, the **48 kW models are the closest capacity match**. Estimated installed totals are approximately **$41,200–$51,200** for Generac and **$41,700–$51,700** for Kohler. - **Expanded-service maximum considered here:** The comparable **60 kW models** are approximately **$45,700–$57,700** installed for Generac and **$46,300–$58,300** for Kohler. Do not pay for this tier unless the completed load calculation and motor-starting analysis show that 48 kW plus load management is insufficient. >[!important]- insight >The small MSRP differences between matched Generac and Kohler units are not large enough to drive the decision. The transfer-switch design, fuel-system work, load-shedding controls, warranty support, and competence of the local servicing dealer can change both the real price and the outage experience much more than a $200–$900 product-price difference. ## Pricing basis Prices below use manufacturer-listed U.S. MSRP viewed on August 16, 2026. **Product cost** is the generator plus a transfer switch only when the cited product is sold as a package. **Installation allowance** is a planning range for the remaining transfer equipment where needed, load-management controls, pad, normal delivery, permits, ordinary electrical and fuel connections, startup, and a cold-weather package. **Estimated total** is product MSRP plus that allowance, rounded to the nearest $100. The installation allowances are deliberately broader than a basic installation average because this property has multiple panels, several motor loads, and an unresolved service topology. Generac states that typical home standby projects commonly total $8,000–$16,000 installed, while broader market guides place installation labor and related work for systems above 20 kW around $5,000–$12,000 or more before unusual site work ([Generac installation overview](https://www.generac.com/resources/home-management/backup-generator-installation/), [HomeGuide generator cost guide](https://homeguide.com/costs/generator-cost)). The larger liquid-cooled allowances below are analytical estimates, not manufacturer or local-contractor quotes. These totals **exclude** sales tax, financing, the future 320/400 A utility-service upgrade, major gas-meter or main replacement, propane storage, long trenching or boring, utility-transformer work, landscaping or structural restoration, and unusually complex code corrections. ## Current electrical layout ### Pricing comparison | Comparison tier | Manufacturer and model | Product configuration | Approximate product cost | Approximate installation cost | Estimated total | | --- | --- | --- | ---: | ---: | ---: | | 26 kW managed-load value | [Generac 26 kW G0073280](https://www.generac.com/residential-products/standby-generators/) | Air-cooled generator and 200 A service-rated ATS package | $8,219 | $7,000–$13,000 | **$15,200–$21,200** | | 26 kW managed-load value | [Kohler 26RCAL](https://www.kohlerhomeenergy.rehlko.com/products/home-generators/26rcal) | Air-cooled generator and ATS package | $8,414 | $7,000–$13,000 | **$15,400–$21,400** | | 38–40 kW managed comfort | [Generac 40 kW XG04045ANAX](https://www.generac.com/residential-products/standby-generators/gaseous/40kw-standby-generator-4-5l-120-240-single-phase-xg04045anax//) | Liquid-cooled generator; ATS purchased separately | $23,869 | $12,000–$20,000 | **$35,900–$43,900** | | 38–40 kW managed comfort | [Kohler 38RCLC](https://www.kohlerhomeenergy.rehlko.com/products/home-generators/38rclc) | Liquid-cooled generator; ATS purchased separately | $22,949 | $12,000–$20,000 | **$34,900–$42,900** | ### Specification comparison | Model | LP / natural-gas output | Rated current at 240 V | Cooling / engine | Speed | Published sound at 23 feet | Transfer switch | Warranty and monitoring | | --- | ---: | ---: | --- | ---: | --- | --- | --- | | Generac 26 kW G0073280 | 26 / 24 kW | 108 / 100 A | Air-cooled, 997 cc | 3,600 rpm | 55 dBA exercise; 67 dBA normal | 200 A service-rated ATS included | 5-year limited; built-in cellular connectivity | | Kohler 26RCAL | 26 / 24 kW | 109 / 100 A | Air-cooled, 999 cc | 3,600 rpm | 56 dBA exercise; 67 dBA full load | ATS included | 5-year limited; remote monitoring included | | Generac 40 kW XG04045ANAX | 40 / 40 kW | 167 / 167 A | Liquid-cooled, 4.5 L | 1,800 rpm | Quiet-Test exercise; obtain comparable dBA in bid submittal | Separate | 5-year / 2,000-hour limited; cellular connectivity | | Kohler 38RCLC | 38 / 38 kW | 158 / 158 A | Liquid-cooled, 2.2 L | 1,800 rpm | 54 dBA exercise; 62 dBA full load | Separate | 5-year limited; remote monitoring included | The Kohler 26RCAL publishes a 39 kVA peak motor-starting rating, and the 38RCLC publishes 74 kVA. Generac's cited current public pages do not present a directly comparable figure for these two models, so bidders should supply the same motor-starting metric for a fair comparison. All four models publish less than 5% total harmonic distortion or suitability for sensitive residential electronics, but the proposal should confirm voltage and frequency performance under the property's actual largest starting step. ## Future 320/400 A service with a 200 A garage These comparisons assume the future service is divided so that the generator transfers the **200 A house side**, while EV chargers and most large garage resistance loads remain on the non-backed-up side. The estimates do not include a 320/400 A whole-service transfer arrangement. Transferring the entire future service would require different and potentially multiple transfer switches, additional engineering, and a substantially different budget. ### Pricing comparison - [[Generac Power Systems]] - [[Kohler Generators]] | Comparison tier | Manufacturer and model | Product configuration | Approximate product cost | Approximate installation cost | Estimated total | | --- | --- | --- | ---: | ---: | ---: | | 48 kW house-side match | [Generac 48 kW XG04845ANAX](https://www.generac.com/residential-products/standby-generators/gaseous/48kw-standby-generator-4-5l-120-240-single-phase-xg04845anax//) | Liquid-cooled generator; ATS purchased separately | $25,179 | $16,000–$26,000 | **$41,200–$51,200** | | 48 kW house-side match | [Kohler 48RCLC](https://www.kohlerhomeenergy.rehlko.com/products/home-generators/48rclc) | Liquid-cooled generator; ATS purchased separately | $25,703 | $16,000–$26,000 | **$41,700–$51,700** | | 60 kW added headroom | [Generac 60 kW XG06045ANAX](https://www.generac.com/residential-products/standby-generators/gaseous/60kw-standby-generator-4-5l-120-240-single-phase-40kw-standby-generator-4-5l-120-240-single-phase-xg06045anaxd/) | Liquid-cooled generator; ATS purchased separately | $27,699 | $18,000–$30,000 | **$45,700–$57,700** | | 60 kW added headroom | [Kohler 60RCLB](https://www.kohlerhomeenergy.rehlko.com/products/home-generators/60rclb) | Liquid-cooled generator; ATS purchased separately | $28,304 | $18,000–$30,000 | **$46,300–$58,300** | ### Specification comparison | Model | LP / natural-gas output | Rated current at 240 V | Cooling / engine | Speed | Published sound at 23 feet | Transfer switch | Warranty and monitoring | | --- | ---: | ---: | --- | ---: | --- | --- | --- | | Generac 48 kW XG04845ANAX | 48 / 48 kW | 200 / 200 A | Liquid-cooled, 4.5 L inline four | 1,800 rpm | Obtain comparable dBA in bid submittal | Separate | 5-year limited; built-in cellular connectivity | | Kohler 48RCLC | 48 / 48 kW | 200 / 200 A | Liquid-cooled, 6.2 L V8 | 1,800 rpm | 57 dBA exercise; 61 dBA full load | Separate | 5-year limited; remote monitoring included | | Generac 60 kW XG06045ANAX | 60 / 60 kW | 250 / 250 A | Liquid-cooled, 4.5 L inline four | 1,800 rpm | Obtain comparable dBA in bid submittal | Separate | 5-year limited; built-in cellular connectivity | | Kohler 60RCLB | 60 / 58 kW | 250 / 242 A | Liquid-cooled, 6.2 L V8 | 1,800 rpm | 57 dBA exercise; 61 dBA full load | Separate | 5-year limited; remote monitoring included | Kohler publishes peak motor-starting capability of 113 kVA for the 48RCLC and 144 kVA for the 60RCLB. Generac publishes high motor-starting capability for the XG line, but the cited product materials do not expose the same directly comparable kVA values. Require both bidders to calculate the largest accepted starting step using the air-conditioner, well-pump, and other motor nameplates rather than comparing marketing labels. ## Significant differences | Decision factor | Generac | Kohler | Why it matters here | | --- | --- | --- | --- | | 26 kW package | $195 lower MSRP; same 24 kW natural-gas output; integrated cellular connectivity | Nearly identical output and sound; remote monitoring included | Treat this as a dealer-and-installation comparison, not a capacity decision | | 38–40 kW tier | 40 kW and 167 A on either fuel; $920 higher MSRP | 38 kW and 158 A; publishes 54/62 dBA and 74 kVA starting | Generac offers modest capacity headroom; Kohler offers a lower MSRP and unusually clear acoustic and starting specifications | | 48 kW tier | $524 lower MSRP; 4.5 L inline-four engine | 6.2 L V8; 113 kVA published starting; 61 dBA full load | Output is identical, so installation design and dealer support should dominate | | 60 kW tier | $605 lower MSRP; full 60 kW and 250 A on natural gas | 58 kW and 242 A on natural gas; 6.2 L V8; 144 kVA published starting | Generac has a small natural-gas output advantage; Kohler supplies clearer motor-starting and acoustic data | | Controls and service | Mobile Link ecosystem and built-in cellular on cited models | Included remote monitoring on cited models | Confirm subscription costs, signal method, remote alerts, and who responds to alarms | | Transfer equipment | Included only in the cited 26 kW package | Included only in the cited 26RCAL package | Liquid-cooled bids must identify the exact service-rated ATS, load controls, and whether they remain useful after the service upgrade | ## Recommendation 1. **Request four current-layout bids:** one Generac 26 kW, one Kohler 26 kW, one Generac 40 kW, and one Kohler 38 kW. Require every bidder to price the same outage load list, automatic shed sequence, fuel work, cold-weather equipment, and warranty service so the totals are genuinely comparable. 2. **If the current project comes first, favor the 26 kW tier only when the contractor demonstrates that one air conditioner at a time, the well pump, furnaces, refrigeration, and other priority loads can operate within both running and starting limits.** Otherwise, the 38–40 kW tier is the stronger comfort-oriented fit. 3. **For the future project, use 48 kW as the base bid and 60 kW as the alternate.** A 48 kW unit already equals the nominal 200 A × 240 V house-side capacity; 60 kW mainly buys motor-starting and future-load headroom, not permission to transfer an unlimited 320/400 A service. 4. **Choose the dealer as carefully as the brand.** Compare response-time commitments, technician coverage, preventive-maintenance cost, warranty labor practices, parts stocking, monitoring fees, and references for liquid-cooled residential installations. ## Bid checklist - Exact generator model, fuel rating, voltage, phase, and current - Exact transfer-switch model, service rating, enclosure rating, and whether it is included in the equipment price - One-line diagram showing every panel and which loads transfer - Calculated running load, largest motor-starting step, and safety margin - Automatic load-shed sequence for both air conditioners, dryers, pool equipment, barn/shop heat, and future EV chargers - Natural-gas meter, regulator, pressure, pipe-size, and full-load fuel-demand verification, or propane tank and vaporization design - Pad, clearances, sound-location review, permits, inspections, startup, battery, cold-weather kit, delivery, and restoration - Monitoring hardware, connectivity method, subscription fees, and alarm-response responsibility - Warranty term, labor coverage, maintenance schedule, annual service cost, and emergency response time - Separate allowance for the future 320/400 A service work so generator pricing is not obscured by an unrelated service-upgrade scope >[!warning] >These are budget ranges for comparing proposals, not contractor quotes. Product prices, promotions, freight, taxes, code requirements, gas capacity, trenching, and contractor workload can change the installed cost materially. Obtain a documented load calculation and at least two complete local bids per size tier before purchasing equipment.
