I appreciate your input/advice here.
We don't have hydro available on our property, so last year I built a system to run the well pump. The system is using 6x225W connected 3x in series and then both strings in parallel as at the end I can run directly the pump with max 90VDC. The well pump is very flexible in term of power; it has a generous power range 30-300VDC or 90-240VAC.
Because I'm planning to build an automated irrigation system in spring, I'll need 12V battery to run the valves and timer. In order to charge the battery I'm planning to connect the charger to one of the panels from system. The charger is PWM type LMS2430 which accept max 40V input. For baterry I'll use 2x 6V Trojan T105-RE in series.
Do you see any problem taking the power to charge the batteries from one panel in the system?
Thank you.
