@maruno @TechConnectify I built my own 20kWh + 5kW off grid setup, batteries included, for about 2000 euros.LFP cells cost about 40-100 per kWh, you just have to add a BMS, inverter and some cables.The expensive part is people. Same goes for the panels; 5kw of panels is 500€, but getting them put on your roof and cabled and all that costs (sometimes tens of) thousands, because there aren't a lot of people who do it and they want a high profit margin.Happy to show you how to do it though
