EG4 EG4-12000XP 12kW Off-Grid Inverter/Charger

put this in a small cabin and it powers lights fridge small heater and a few tools just fine. it holds up under motor loads and can handle a bit of harsh weather cause its built pretty solid. the 12kW rating is more than enough for a modest home and leaves room for expansion later

EG4 EG4FLEXBOSS18 13kW Hybrid Inverter/Charger

works great for daily power management. it sends solar to loads then batteries then grid. setup took a bit of time but once its dialed in its stable

EG4 EG4LIFPOW4WM-48V280A 14.3kWh 280Ah 48V Wall-Mount Indoor...

running this off a 12 panel array out here in rural kentucky. powers the whole house through the night most days and on cloudy days i still get 6-8 hours easy. LFP chemistry is the way to go if you ask me, way safer than NMC. been about 5 weeks zero issues. would buy again no question

what happens if it gets really cold outside like below freezing, will it still work

A1 SolarStore

Great question! As a self-heating battery, it's still possible to use this battery below freezing. The internal heater activates when the battery temperature falls below 32°F. When activated, the heater warms the battery until it's safe to charge or discharge again. So yeah, you're covered even in harsh winter climates.
