during use
1. Excessive load at output.
2. Internal temperature
is too high.
1. Reduce load to less than rated power.
2. Let the Inverter cool down for at least 30
minutes. Make sure that the fan is not blocked
and that the Inverter has sufficient ventilation.
No output voltage. 1. Cords not connected properly
2. Fuse on battery bank open
3. Internal fuse(s) open
4. Low input voltage
5. Loose or corroded connection
6. High input voltage
1. Check and secure connections

Output voltage
is incorrect
Input voltage is too high or too low Maintain input voltage at required level
Could not drive load 1. Load power is too large
2. The AWG of the wire is too low
3. Start power of an appliance is
up to twice the rated power.
1. Lower load level
2. Use appropriately-sized wire connections
3. Reduce load, or change appliances
Motor-operated
device operates at
