If you have an unused emergency lighting circuit board, you can repurpose it for a DIY inverter project.
First, use scissors to cut off the excess wiring.
Next, remove the remaining unnecessary auxiliary branches from the circuit board.
After several rounds of trimming, you will be left with the core inverter circuit.
Connect the wires and attach an electrical outlet.
You can then use the battery to power 220V electrical appliances.
Wiring Instructions:
Connect A, C, and D together as the positive terminal. Connect B to the negative terminal. Connect α and β to the electrical outlet.
