Small Pure Sine Inverter (300w - size depends on fridge)
Diagram
Wiring using Sonoff SV
The trace is 2 mm wide. By assuming the PCB trace thickness is 1 oz/ft^2 you can calculate the current: 2A
If you are using more than 2A be sure to put more solder on the solder traces.
Wiring using Shelly 1 Plus
The Shelly 1 Plus with the Shelly Plus Addon should be able to handle the power requirements.
