Energy Score explained

We score each model 0–100 on round-trip efficiency, warranty depth, cycle life, compatibility with common inverters, and price per kWh where capacity is known.

Compare before you buy

Use the compare tool to line up three models by specs and price. Prioritize in-stock units with clear warranty terms and UL listings where required by your AHJ.
