I’m definitely a noob but am looking for some direction before I take my system in for repair. I am currently not able to charge my system with either solar or shore. I am getting a notification alarm of “A-B11: Under Voltage” for my Smart BMS PD4? My system consists of:
Victron 12v 200 Ah LiFePo4 Smart Lithium Battery (3)
-Victron Multiplus 12/3000/120-50 120V Inverter/Charger
-Victron Smart BMS CL 12-100
-Victron Smart Solar MPPT 100/50 Charge Controller
-Victron Smart Battery Protect 12/24-100A
-Victron Smart Battery Protect 12/24-65A
-Victron Smart Shunt 500A/50mV
-Victron Cerbo GX
-Victron GX Touch 50
-WFCO Combination Breaker/Fuse Panel 110V/12V
-BlueSea Passenger Side 12V Compact Fuse Panel
I keep the van in storage so I take it out periodically to charge via alternator/solar. I was down to 76% and two days later it was dead. I may have left something on? I have been unable to get it to take a charge since. I am planning on taking it into a local service center but wanted to see if I could get a better understanding of what I may be dealing with first. Thanks for the help!
