What can cause an inverter to shut off due to voltage level?
If an inverter keeps shutting off, it can be due to voltage level being too high and the inverter cable not being thick enough to handle the incoming power. This is often for safety reasons.
How do I troubleshoot my inverter?
Here’s how to troubleshoot: Check the Battery: Ensure that the battery is fully charged. If the battery voltage is too low, the inverter may not turn on. Use a multimeter to measure the voltage. If it’s below the required level, recharge the battery or replace it if it’s defective.
What should I do if my inverter doesn't produce power?
If your inverter turns on but doesn’t produce any output power, consider these steps: Verify the Load: Ensure that the load connected to the inverter is within its rated capacity. Overloading the inverter can cause it to shut down or not produce any power. Disconnect all loads, reset the inverter, and reconnect them one at a time.

How much power does an Inverter use just sitting there idling?
Many inverters have a automatic standby mode. They shutdown inverter to save idle power and wake up every so often to see if an AC output load exists. Issue with standby mode is it takes a minimum output AC load to be detected by inverter. A light load may not be recognized and inverter will just continue its intermittant active-sleep cycle.
Understanding Inverters
I would suspect that there is a low battery voltage protection circuit in the inverter and when you turn on the heater the inverter will need to draw around 42 to 45 amps from the battery and if the battery is only rated at 100Ah then the battery voltage will start to drop quite quickly and the inverter will shut down.
