•
Break in battery connection
•
40A fuse inside the inverter is blown due to
reverse polarity or defect in the unit.
•
Output voltage pulses clipped due to
overload or short circuit in output
•
Low battery shut-down due to discharged
battery or excessive voltage drop in the
cabling from the battery to the inverter.
•
Over temperature shut down.
•
Inverter wrongly connected to 24V Battery
instead of 12V Battery.
Charging alternator's voltage has been set
•
beyond 15V, or it's regulator has become
defective.
Batteries are being charged simultaneously
•
from an unregulated solar panel set beyond
15V
Batteries are connected to a battery charger
•
with its boost voltage set beyond 15V
The starting current required by the load is
•
higher than the surge rating of 500 watts
•
On cranking, the battery voltage drops
below 10V
•
Check connections are tight
•
Replace the fuse. If blows again, the unit needs
to sent for repair.
•
Reduce load/ Remove short
•
Re-charge the battery
Ensure cable from battery to inverter is thick
enough to carry 30A (AWG#10)
Ensure connection from battery to the inverter is
tight and firm.
•
Switch off the unit to cool down.
Improve ventilation and ensure fan inlet and
vent holes are not blocked.
Reduce load.
•
Ensure battery is 12V
Set the voltage correctly or repair the alternator
•
Ensure that the voltage of solar panel does not
•
exceed 15V
Ensure that the boost voltage of the battery
•
charger is less than 15V
Use inverter with appropriate surge rating.
•
•
Switch OFF the inverter when cranking the
engine.
