My trusty old Epever tracer 4210rn unit decided not to start up after a shutdown (changed some cables / shunts etc)
no LED display when the batteries are connected.
we pulled it apart to see if there was something obvious.. the main MPPT caps were way out of tolerance... (they were potted, and will may require some digging to get them out and replaced.
The main problem is the 5v rail to the electronics (control circuits?) is dead shorted and we think a voltage regulator has failed.
SO THE QUESTION: does anyone have a circuit diagram for this unit? pcb schematics?
i have bought a replacement charge controller but would like to see if i can get the the old tracer working again..
Cheers,
Richard
