Folks...
I've always enjoyed build things electronic.
Here are some of my charge controllers I've designed and built.
I'm mike
This is the Micro P charge controller. It does 20A. It is also RF silent. That means it doesn't make any RFI that could get into radios. That's important if you're a ham radio operator.
This PWM controller is good for 30A
N
The pcb below is a proof build of another PWM controller. In theory it will support 120A at 48V.
This guy. oh, he was a lot of fun to design. IT's a relay based controller I called the "old school PVC" The logic switched a mercury displacement relay. Easily do 100+A at 48V. The digital display counts how many times the relay was operated during the day. I put it in there as a trouble shooting device, but liked it so much it stayed in the final design.
