Hello everybody,
I have a regulator for my solar installation, but unfortunately it "overcharge" my batteries (it let the charge voltage up to 17V) It brings literally my batteries to bubble over.
So I constructed a "limiter" to work like a switch (v>14.5 stop the regulator, v<=12.2v restart it). It works but I would prefer an other solution.
I would like to limit the voltage at 14.5v - but the current can go up to 20Amps.
My first guess was to use a Zener diode to limit it, but I cannot get one of 20 Amps here in Mexico. :-/
I have some power transistors, can I use them somehow ?
Thank you very much for an answer.
