Field notes
An inverter converts your battery bank’s DC power to the AC power your appliances need — and the type, size, and features matter more than the brand name on the box. Pure sine wave inverters produce a clean AC waveform nearly identical to shore or grid power — safe for sensitive electronics, medical equipment, and modern appliance motors.
Sizing to your actual loads
Size for your highest simultaneous load plus the startup surge of motor-driven appliances like a compressor fridge or AC unit — surge draw is often several times the running wattage.
