Some days ago, I’ve mounted a PV Solar on the roof of my home.
It’s a 2.66 KW of SunPower E20/333 with a SUNNYBOY inverter.
Now, it’s time to upgrade my PCB circuit with a new one for measuring of 2 current sensors and 1 voltage sensor.
The circuit also controls one LCD display.
After about 1 hour of study with Eagle, it’s ready:
One of the next days I’ll convert it to STL for print with POWERWASP 3D Printer.
