With power issues in Nigeria (basically no power from my perspective), I have been building my home solar system. Currently at 9kw solar panels, 10kva inverter with 30kwh Chinese LFP. Spent about $7,000 so far. Looking to eventually get to 60kwh and at least 20kw in panels because of air conditioning needs.

Waiting for government, my kids currently in primary school would probably have graduated from college before they fix the power situation (they are currently fixated on building roads to nowhere).
