Remedy :
Push the power switch to the ON
position.
Clean battery terminals or inverter wire
contacts. Tighten battery terminal
screws.
The inverter has to be returned for
service.
Replace battery.
Remedy :
Replace battery or charge it first.
When extending the battery wires of the
inverter make sure you use the correct
wire gauge (≥ 1.5 times larger than the
fixed battery wires). It's not advisable to
extend the battery wires to more than 3
meters.
Check your electrical system or consult
an electrical engineer to check it for
you.
