The following problems may occur when you are running your power inverter, so it’s better to be prepared and know what to look for when it happens.

1:  You notice that the backup power run time is less than expected.  Here are some possible causes and suggested solutions for this problem.

CAUSE:   The AC product power consumption is higher than rated and reduce you power consumption.

REMEDY: Increase your battery bank  to make up for increased power requirement.

CAUSE:  The battery is old or defective.

REMEDY:  Replace the battery.

CAUSE:  Battery is not being properly charged.

REMEDY:  Check the battery terminals to make sure they are not loose. If loose, call for a technician to tighten it.

CAUSE:  Power dissipation in the DC cables,(i.e. Cables are hot)

REMEDY:  Use shorter/heavier DC cables.

2:  The fault light comes on and system will not operate.

CAUSE: Overload has caused system to shutdown.

REMEDY:  Reduce connected by turning off some appliances and restart the system.

CAUSE:  Your battery is discharged (alarm is sounding).

REMEDY:  Recharge the battery bank.

CAUSE:  The inverter has overheated due to poor ventilation and this has caused over temperature shutdown.
