Hi I have a Quattro 24/5000/ it’s been running fine for 3 years now it’s having charging issues when I run the generator the input voltage fluctuates and the inverter resets the charge current jumps all over the place and the inverter has a pulsing transformer humming noise,.
The inverter side works fine it’s also doing it on shore power I have disabled the charger in the setup and loaded the generator up and the voltage is stable as I thought it might have been a faulty AVR is it possible the charger in the inverter is damaged? I have tested all the batteries and checked connections.
system is
Quattro 24/5000
Bluesolar 60/150
Cerbo GX with display
BMV 712
10 KVA marine genset
24v 600Ah VRLA bank
Victron battery balancer
Any thoughts would be very much appreciated thanks.
