if anybody can shed any light or assist with advice in any way, that would be very much appreciated. 3kva Axpert-type inverter 24v battery bank Incoming pv voltage ~44v Inverter works. When PV is connected, it registers 24v and starts charging. When charging, every few seconds, it shows it charges at a volt or two less, gradually down to the voltage of te battery bank. Operating voltage range correct at 30 – 32 vdc Max v 60vdc Everything within specs. Once inverter has stopped charging and PV disconnected, there is still 24v between combiner box and inverter as if the inverter is powering backwards towards the combiner box. Individually tested strings and they're all good. What could possibly be the problem? If there's any help out there, we'd be most grateful!
