Trouble Shooting

The measured output current of the inverter is too low

CAUSES

SOLUTION

The range of reading of common ammeter is

too small

Measure modified sine wave with a real

effective value multimeter to get the accurate

data

Too low current of the inverter

Charge the battery or change the battery
