An inverter proves to be an extremely important and useful device for homes and offices.  What it does is that it provides us with electrical current and power during power cuts so that our day to day activities are not hindered.  However there are some cases when the inverter won’t work or would stop working unexpectedly. In such situations, we won’t receive any power output and may thus face troubles. This is why it is essential to know the cause of inverter battery for home not working and also the appropriate solution. The following is a list of reasons for inverter not working:

1. Defective power switch

REASON: One of the most common reasons for inverter not working or not turning on is a defective power switch.

SOLUTION: For this, you may need to unplug the inverter from the power source and plug in some other appliance into it. Turn on the appliance and see if it is working. If not, then your power switch is defective. In this case you may need to get the power switch replaced by a professional. If the appliance does turn on then that means that the problem is with the inverter itself.

    I recently tried installing a 3000W inverter in my RV trailer, and had to run about 15 feet of wire from the batteries. I believe I used 6 gauge wire. After hooking the unit up, it could only run devices rated at 300W or less. Plugging in anything greater would not work, and the inverter would beep. Is this because of the “small” wire that I ran???
