DC flows in one fixed direction with positive/negative poles. AC alternates direction, has live & neutral wires, and matches grid waveform to run motors and home appliances.

Pure sine wave is identical to grid power, quiet and safe for AC, fridges and water pumps. Modified sine wave has stepped waveform, causes overheating & buzzing on motors, only fit for lights and phone chargers.

Yes. DC has strict polarity; reversed positive and negative poles burn power components instantly. Reversed live/neutral on AC side rarely damages the unit.

Batteries store DC power. Small DC loads like lights can run directly on DC. AC loads such as air conditioners, washing machines and sockets use inverter-converted AC power.

1. Low DC input voltage (low battery power);

2. Thin DC cables cause big voltage drop;

3. Load power exceeds inverter rated power.

Check AC short circuit, overload protection trigger, overheat shutdown due to poor cooling, or damaged waveform drive module.
