I'm still in the shakedown portion of my new system. I'm having a problem when I put large loads on my Inverter (Giandel 2200Ksc 12v). Smallish loads, 50 amps or less, everything works as expected. Larger loads (my hot water heater 1500W, vacuum cleaner 700W) sees the DC voltage from my 2 271Amp Hour Lithium batteries (CATL Cells, OverKill Solar BMS) settle down at around 13V. My smart shunt shows 100 amps being drawn. Tracking voltage from the batteries to the inverter I see .3V DC loss (2 circuit breakers, two 6' 00 cables). This gives 12.7V at the inverter. After a minute or so the inverter goes into low voltage (says <12.1) and shuts down. Checking the voltage on the inverter terminals I see very low voltage 4V or so. Shut everything down. Batteries go back to charging, all voltages look OK. Turn on inverter, looks fine. Add 1500 watt load and the whole thing repeats.
Do I have a bad inverter?
Thanks in advance!
