the specified TrueRated

max output.
PROBLEM: Inverter Shut Down – Fault LED Lit
Reason Solution
Equipment being operated draws too 
much power.
Do not use the equipment with this 
inverter; use a higher wattage inverter.
PROBLEM: No AC Output – Yellow Ground Fault LED Lit
Reason Solution
Ground fault is unintended AC current 
that is flowing to ground. It can be 
caused by faulty wiring, bad insulation, 
very long wiring, and sparking 
appliances.
Turn inverter OFF (O) to reset it, then 
to ON (I). IF the inverter immediately 
shuts off, disconnect each appliance 
or wiring until the inverter will stay 
on after reset. Examine the wiring or 
appliance for unintended connections. 
Repair or replace as necessary.
