I would start simple and charge that battery to SOK’s stated fully charged voltage. You know it’s not DC over voltage. So it’s DC under voltage or AC over amperage on startup. The freezer may work as a fridge but the start amps may be higher than if it were working at 0 deg f. You could switch back to freezer mode. The thermostat cycle differential may be smaller on the fridge setting causing a restart before refrigerant is fully equalized. We already know the refrigerant will be at higher pressures than at freezer temperatures. From the picture I don’t think you have adequate ventilation on the sides. The condenser will be hotter as a fridge than freezer.
The manual points to a Over Voltage fault and its been suggested the Inverter is defective. But I do agree with your thoughts on pressures.
After working in the commercial HVAC/R field for 30 years, I have been very aware of compressor overload due to high evaporator temperature loads. We used various methods to overcome the pull down load over current condition, a crankcase pressure regulator was one. This is totally un-related to her problem but to correct folks who get info off Google and post here.
Crankcase Pressure Regulators
A crankcase pressure regulator (CPR) is a common accessory added to many low-temperature refrigeration applications, such as walk-in and reach-in freezers. The selection of a CPR is based on five system considerations.
