Thanks for your quick reply. In 2022 I installed the panels and with it 2 5kW batteries. This one I included in the 2022 and got 30% credit.
In 2023, I added another battery 14kW, which is the only cost I am including in the 2023 year tax. All batteries meet the main home use and also charged by solar only (not grid).
Researching through google more, it looks like in 2022 and 2023 Residential Clean Energy Credit (30%) applies, but then there is the Inflation Reduction Act which applies from 2023 and on (30%)?
