possible Causes

probable Solutions

Inverter shuts off 

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
2.  Check battery bank fuse and 

replace as needed.

3.  Have technician check internal fuses 

and replace as needed.  Only a qualified 

technician should open housing.

4.  Recharge or Replace Battery
5.  Clean and tighten connection
6.  Remove charging source and make 

sure correct battery is being used 

and connected correctly.

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 

incorrect speed

Load is only inductive

Operate a lamp or heater at the same 

time to provide a more balanced load.

Television picture is full 

of static or speakers 

make a buzz

1.  Television or radio interference 

2.  Incompatible device

1.  Move Inverter away from antenna and/

or use a shielded antenna cable.

2.  Contact device supplier to make
