Hello John,
The Redarc R-12-400RS-NA 400W inverter # RED73RR is a great fit for your 280Ah LiFePO4 battery and your planned use. Based on your setup, running LED lights for a few hours, using the water pump for two quick showers, and if you even needed to charge your phone, speaker, or laptop you’ll only use about 290 watt-hours per day, or around 8% of your battery’s capacity. This inverter provides plenty of power for small devices like lights, fans, chargers, and even a small TV, and it can handle brief power surges up to 800W. It’s efficient, doesn’t waste power when idle, and is compact and reliable.
I take it you are mainly a BoonDocker, how often do you get out camping?
