Notes

All protection is automatically recovered.
To protect the battery, if the unit needs to be restarted 

after low voltage protection, the voltage of DC input should 

be above 12V. 
To extend the life of the fan, it will stop when there is no 

load. The speed of the fan increases as the load increases.
The unit is completely insulated in input and output for 

added safety.

Problem/Symptom
Low output voltage 
No output voltage 

No output voltage 

after prolonged use

No output voltage, 

“Protect” indicator 

lighted

No output voltage 

No power to 

inverter 
Low battery alarm 

on all the time

Possible Causes
Overload 
Low input voltage
 

 

Thermal  

shutdown
 

 

 

 

 

 

 

 

High input  

voltage
 

 

 

Short circuit 

Blown fuse 

in CLP
Poor DC wiring 

Poor battery 

condition

Solution
Reduce the load.
Recharge battery. 

Check connections 

and cable.
Allow inverter  

to cool off.
Reduce load, 

continuous 

operation input 

current required.
Improve ventilation; 

Make sure ventilation 

openings in the 

inverter are not 

obstructed.
Reduce ambient 

temperature.
Make sure  

the inverter is 

connected to  

12V battery.
Check regulation  

of charging system.
Check load for 

proper operation.
Replace fuse. 

Check 

connections.
Make sure battery  

is fully charged.
