Small Pure Sine Inverter (300w - size depends on fridge)


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.
