Please help or assist in my charging issues.
Firstly I am running 5, 200W 24V panels which are wired in parrael with all panels fused. Solar regulator is PWM 50 amp unit. Battery bank, I am running x4, 12v 200 amp batteries wired to produce 24v. Inverter / charger unit, rated at 3000 watt. Cable from panels to battery bank is three fase Orange power cable which I believe is rated at 10mm which given there are 5, cables I have two cables linked up for positive and same for negative so should have overall rating of 20mm. Length of cables from panels to regulatior is around 30 metres.
Voltage test just after panel was 42 v and same voltage tested just before regulatior 30 meters away from panels.
Charging issue, batteries will charge through inverter/ charger powered via generator but not through solar, regulator has been changed over but with replacement unit still doing the same and not charging.
Regulator specs, 12 /24v , 50amp Low voltage connection 25.2v which batteries have been as low as 24v
Question, if each solar panel is rated at 10amp x 5 = 50amp , being the regulator is only rated at 50amp would or could this be slightly undersized ?
Any help would be much appreciated as my Melbourne supplier is being of no help
