I'm building a solar generator and using the GoWISE pure sine wave 1500W inverter here: https://www.amazon.com/gp/product/B01COA0UTE/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1.
Up to this point the inverter has performed flawlessly with resistive loads. I can run a 1500W heater pulling 120+ amps from the battery with no issues. I've run the 30 year old upright freezer in my garage for 8 hours. But now, I've tried to run a much newer (10-12 year old) refrigerator and the inverter keeps throwing a fault and turning off. My ammeters show the peak load is under 60A right before it faults. I can hear the compressor starting but I'm baffled to why it's failing when the current is half of what I've seen it do continuously. In my kill-a-watt tests the older freezer uses more kWh in a day than the refrigerator and the startup current is at least as high and probably higher (80A). Yet it can run the freezer just fine. So weird.
I hate to send this inverter back but I'm not sure what else to do.
