I have a brand new Multiplus 24/1600/40-16. When powered from mains or battery, the Inverter, Charger and Alarm LED's on the front flash continuously.
The battery voltage is 26.4Vdc (measured with multimeter), but in VictronConnect it reports 46.7Vdc and the status is Fault. I have upgraded it to the latest firmware (475), but it has made no difference. It won't charge the battery and is reporting a battery ripple fault whether the battery is connected or not.
Should I return it to the supplier, or is there something else I can try to fix the problem?
