Hi i have a Mecer 8kva unit. It was working well till is started having error F12 DC DC voltage high. It read PV 567 volts with out any PV connected on both Mppts and batter voltage 75 volts with no battery connected . but with AC in only. When PV and battery is connected it shows the same voltages and F12 please hwlp
My rule of thumb . dont open something u bought brand new if it doesnt work 2 ask for ut to betested in store when u retyrn it and the replacement shouls be tested as well
The limitation is with the inverter , I usually installl digital timers for things like pumps for my clients, that is the borehole only runs between for exams 9am and 12 pm to fill up the tank , at those times another timer will not allow the pool pump to be on at the same, mutually exclusive timers
