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.
First Problem: You bought a power inverter and hooked it up to the battery. Eventually, you notice that the battery run time is less than expected. Here are some possible causes and suggested remedies for this problem.
CAUSE: The AC product power consumption is higher than rated.
REMEDY: Use a larger battery 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: Many simple chargers are unable to charge a battery fully. Replace your charger with a better model.
CAUSE: Power dissipation in the DC cables.
REMEDY: Use shorter/heavier DC cables.
Second Problem: This time, after you hook up the power inverter to the battery, the AC product will not operate and/or the red FAULT light comes on. Here are some possible causes and suggested remedies for this problem.
CAUSE: AC product(s) connected are rated at more than the rated continuous output power and overload shutdown has occurred.
REMEDY: Use a product with a power rating less than the rated continuous output power of your inverter, or get an inverter with more output power.
CAUSE: AC product is rated less than the rated continuous output power, but the high starting surge has caused overload shutdown.
REMEDY: Your product exceeds the inverter’s surge capability. Use a product that has starting surge power within the inverter’s capability.
CAUSE: Your battery is discharged (alarm is sounding).
REMEDY: Recharge the battery or use another battery that is fully charged.
CAUSE: The inverter has overheated due to poor ventilation and this has caused over temperature shutdown.
REMEDY: Switch the inverter OFF and allow it to cool for 15 minutes. Cleared a blocked fan or remove objects covering unit. Move the unit to a cooler environment. Reduce the load if continuous operation is required and RESTART the inverter.
CAUSE: The input voltage is greater than 17.0V.
REMEDY: Verify that the charging system is properly regulated and the battery is 12V DC nominal.
I hope these problems never happen to you, but if they should, you will know what to look for and hopefully, be able to solve them. You can find more tips, information and suggestions at my website, Energy Igloo.
