Short answer: If your Anker SOLIX F3800 is installed in 2026, there is no federal Residential Clean Energy Credit (Section 25D) to claim. IRS guidance says the 30% credit is not allowed for expenditures made after December 31, 2025, and an expenditure counts as made when the original installation is completed, not when you pay. Battery storage installed by that date needed at least 3 kWh of capacity (IRS; guidance).
The F3800 tax credit question still shows up constantly, and much of what ranks for it was written before the rules changed. This guide sums up what the IRS says now, how the date rule works, what to do if your project straddled New Year's, and how to plan a Las Vegas home backup system on its own merits. It is general information, not tax advice. Your tax professional should make the call on your return.
Why the F3800 question used to come up
From 2022 through 2025, the Residential Clean Energy Credit was worth 30% of qualified costs, and battery storage technology was added as a qualified expense beginning in 2023. The IRS set one size rule for batteries: a capacity of at least 3 kilowatt hours. The F3800 holds 3,840Wh, or 3.84 kWh, so it clears that threshold on capacity alone (calculation).
The harder question was always whether a portable unit counted as battery storage "installed in connection with your home," which is the wording in the IRS Form 5695 instructions. The IRS pages we read for this guide do not name portable power stations specifically, and owner opinions online have been mixed. For new installs, that debate no longer matters, because the credit itself has ended.
Steps to sort out the tax credit question for your F3800
- Find your installation completion date. IRS fact sheet FS-2025-05 says a 25D expenditure is treated as made when the original installation of the item is completed. Your receipt date is not the test.
- If installation was completed in 2026, plan without a federal 25D credit. The IRS says the credit will not be allowed for any expenditures made after December 31, 2025. That is true even if you paid in 2025 and the install finished in 2026.
- If installation was completed by December 31, 2025, talk to your tax professional. The credit is claimed on Form 5695 for the tax year the property was installed, not merely purchased. Your preparer can tell you whether your setup qualified and how to claim it.
- Check for an unused credit from a 2025 install. The credit is nonrefundable, but the Form 5695 instructions say you can carry the unused portion of a residential clean energy credit to 2026.
- Keep your paperwork together. Save the invoice, the installer's completion date, the product spec showing capacity, and any separate invoice for installation labor or wiring. The IRS says qualified expenses could include labor for onsite preparation, assembly or original installation.
- Ask that any quote or calculator leave the credit out. For a 2026 install, a backup estimate that assumes a 30% federal credit will understate your real cost. Ask for numbers without it.
- Size backup for your loads, not for a credit. Pick capacity based on what you need to keep running in an outage, and leave panel, inlet or transfer-switch wiring to a licensed electrician.

Frequently asked questions
Does the Anker SOLIX F3800 qualify for a tax credit in 2026?
Not for the federal Residential Clean Energy Credit. The IRS says the 25D credit is not allowed for expenditures made after December 31, 2025, and an expenditure counts as made when installation is completed. An F3800 installed in 2026 cannot use that credit.
Is there still a 30% solar tax credit in 2026?
Not for homeowners under Section 25D. The IRS lists the 30% rate for property placed in service from 2022 through 2025, and the credit is not available for property placed in service after December 31, 2025. Leased or third-party-owned systems are a different question to raise with the system's owner and your tax professional.
I paid for my F3800 in December 2025 but it was installed in January 2026. Can I claim it?
No, according to the IRS. Its FAQ answers this exact case: if installation is completed after December 31, 2025, the expenditure is treated as made after that date, which prevents a 25D claim even if you paid earlier.
Did a portable power station ever count as battery storage technology?
The IRS rule is a battery capacity of at least 3 kWh, installed in connection with your home. The IRS pages we read do not name portable power stations specifically, and opinions online were mixed. If you installed one in 2025, your tax professional should decide whether it qualified.
Can I still use unused credit from a 2025 install?
Possibly. The credit is nonrefundable, and the Form 5695 instructions say you can carry the unused portion of the residential clean energy credit to 2026. Your preparer can confirm the amount from your 2025 return.
