tvixen / 4KW-230V-Inverter

With these schematics and PCB's, it's possible to create a 230V AC 4KW inverter. The main processor is based on Arduino Nano, with help from a graphic processor Arduino Mega2560, to run the demanding graphic and interface to front buttons.

Relay board schematic is missing #2

Hi Tim, Thank you very much for your beautiful products. I studied the advance board and found that you have connection 2 to relay board print but I could not find it in your document package. I assumed that the relay board is not needed for the Inverter (advanced version) If it possible, please share with us the schematic and also the relay board (if needed for the inverter to work). I am thinking on joining the Inverter with a buck converter for my home solar panels and may consider replacing nano with ESP32 wifi can also work. Please advise me with thanks. Yours very faithfully, Dang Dinh Ngoc

Hi Dang You are right, the relay board is not necessary but only a safety device that facilitates the timing of the charge and discharge for the the large electrolytes. It can charge them and discharge them with resistors and relays. I haven't any schematics for the relay board, but its very simple to make for other engineers.

Replacing the nano with a ESP32 is a good idea, as it have a more powerfull cpu.
