The credit, originally part of the Inflation Reduction Act of 2022 and scheduled to last through 2034, was accelerated to terminate at the end of 2025 with the signing of the "One Big Beautiful Bill Act" on July 4, 2025.
Key Details
Credit Amount: The credit is for 30% of the cost of new, qualified clean energy property for your home.
Eligible Improvements: Qualifying expenses include those for solar panels, solar water heaters, small wind turbines, geothermal heat pumps, and battery storage technology (capacity of 3 kWh or greater).
Limits: There is no annual or lifetime dollar limit on the credit amount for most qualifying property, but it is nonrefundable. Any excess credit can generally be carried forward to reduce tax in future years, provided the credit is still in effect.
How to Claim: To claim the credit, you must file IRS Form 5695 with your federal tax return for the tax year in which the property is installed and placed in service.
Homeowners considering these upgrades should act quickly to ensure installation is completed before the deadline. For more information on eligibility and to find other potential state or local incentives, you can consult a tax professional or use resources like the DSIRE database.
If you are doing TOU augmenting, this only works out math wise if you are spending like $600+ a year on peak usage and year that you can 0 out else repayment time isn't worth it as battery prices will continue to decrease over time and a dollar today is worth way more than a dollar 5 years from now.
If you have solar, this could extend you based on power usage after peak sun...but we found the math just doesn't work, repayment period for us is over 10 years based on night usage and our off peak is 0.08/kw.
So model it out based on your usage to see if it makes sense under 5 year repay.
You should not need a permit to install a portable generator!
Depending on your area/location, You may need a permit for roof mounted panels.
Simply add a transfer switch or interlock kit and a generator inlet box.
It just needs to produce energy to offset your electric bill, if you're worried about IRS sending a pencil pusher to look at your electrical system.
Basically get a cheap/used solar panel and connect it to the DPU, then plug a few items into the DPU and you are good, until your final install.
Community Reviews
EcoFlow Delta Pro Ultra is being framed as a serious whole home backup and peak rate battery system, with enough capacity to keep a house running for a while and strong value at this price. The trolley is included, though it only carries one 6 kWh battery, not the full 12 kWh setup. The federal 30 percent clean energy credit appears to apply to the battery and installation costs if the system is installed and placed in service by December 31, 2025. The main uncertainty is the offer language around installation and eligibility, which is still unclear. It looks most compelling for outage backup or high time of use rates, especially where electricity is expensive.
Common Questions (5)
Battery storage of 3 kWh or greater can qualify for the federal Residential Clean Energy Credit if it is installed and placed in service by December 31, 2025. Installation costs can also qualify, but the paperwork should show completion by the deadline.
A 12 kWh system can run a house for a while, while smaller EcoFlow units are better suited to keeping lights, fridges, freezers, and sump pumps running. For short outages, some shoppers still prefer a gas generator or interlock setup because it can be cheaper.
The listing appears to include the trolley when the page is fully expanded, but the deal text itself does not clearly mention it. The pictured trolley may differ from the 4-wheel tray the unit sits on, so the exact accessory should be verified on the product page.
A common setup uses an exterior inlet, an interior inlet, and an interlock switch at the breaker panel. One cord runs from the generator outside to the outside inlet, then another cord connects the inside inlet to the DPU input, allowing the house panel to be powered or recharged.
It can make sense only when peak-rate spending is high enough to justify the payback, with one example citing about $600+ per year in peak usage and a payback period over 10 years otherwise. In Southern California, 63 cents/kWh TOU rates were cited as making the math more favorable.

I had an extensive 'chat' w/AIs about this - what 'it' said was it comes down to a check-list showing it's configured & running - this is simply incase of an audit.
