What specifications should I look for in a solar battery system?

Key specifications include LiFePO4 chemistry, adequate capacity (kWh), proper BMS (Battery Management System), round-trip efficiency above 90%, cycle life over 4000 cycles, and compatible inverter ratings.

What are the red flags when buying a solar system?

Watch for vague warranty terms, inflated capacity claims, missing thermal management, proprietary components that lock you in, and dealers who can't answer technical questions.

What questions should I ask a solar dealer?

Ask about actual usable capacity, cycle life guarantees, warranty coverage details, system expandability, total installed cost, and what happens if components fail.
