How much power does your Microwave require? Does the microwave require a Pure Sine Wave?

Hello James,

If you're getting the alarm most likely its the battery voltage is dropping too low during the surge.
This could be caused by either:
1. The battery capacity is too small to support the high surge current required to run the microwave. Check the battery capacity
2. The batteries are not charged enough. Check the battery charge status
3. The batteries are not able to hold the charge due to age or damage. Check the voltage at the input terminals of the inverter WHILE the microwave is running
4. The cables from the battery to the inverter are too thin to support the high current needed to run the microwave. Check the cable size
5. There is a loose connection between the battery and the inverter that could be limiting the amount of current transferred. Check the cable connections to make sure it can handle the power

Many of these can be troubleshooted by using a multimeter to read the input voltage to the inverter (at the inverter DC terminals, NOT the battery terminals, while the microwave is in use. If the voltage drops, there's a problem with the source power. If the voltage does not drop and you still get the fault, then there's something wrong with the inverter.
