Hi all, I've asked a similar question before, but after doing some trouble shooting, I still have an issue I'm trying to solve for. I'm converting a Ford Transit 250 into a camper and just finished setting up my electric system last week.
BMV 712 Smart Battery Monitor
MPPT 100v 30A Solar Charge Controller
(3) 100Ah LiFePO4 Battle Born batteries
Giandel 2200W Pure Sine Wave Inverter
Sterling 60A B2B Charger
Progressive Dynamics 60A 12v LiFEPO4 Battery Converter/Charger
What I’m trying to solve for is that when I turn my inverter on, it beeps continuously and says "Lo", indicating low voltage protection, and then shuts off.
I have taken apart the inverter and checked that the fuses are in good shape. (There are 4 30A fuses and they are all good).
I have charged up my battery bank to full, using my PD Converter, and synchronized the SOC to 100% on my BMV 712, as well as input the correct battery monitor settings in the Victron app.
It was previously recommended to me that maybe my main 300A fuse was blown, or that there was a short somewhere. I have used a multimeter to test all connections and I’m getting consistent voltage of over 13v anywhere I test. That leads me to believe that there is not a short, and that the 300A fuse is not blown (I've tested on both sides of the fuse).
However, my BMV 712 will not show any history (please see my updated attachments).
What am I missing here? Does anyone have any suggestions?
