Desperate HELP PLEASE! My van is currently being rented out by a client, and their electrics have gone down. I've recently been having issues with it not working properly i.e BMS saying batteries at 16% full and controller in Float, suggesting they're full. I'm sure it's as simple as a settings issue, I just need to know what settings to use!
Here is my setup:
Victron Energy SmartSolar MPPT Charge Controller 150V/45A-Tr
3 x 200w Solar panels:
Specifications:
- Peak power: 200W
- Maximum power voltage: 38.80V
- Maximum power current: 5.15A
- Open circuit voltage: 45.00V
- Short circuit current: 5.80A
- Power tolerance: 0/+3%
Batteries: Wonston LiFeYPO4 (3.2V/300Ah) x 4 cells.

BMS:
| BMS123SM-SET | BMS123 Smart - Complete Set (4 cells) with Bluetooth 4.0 |
I need to know the following settings, as i think mine are not correct:
I was told, to disable the Equalisation Voltage, that i have to set it to 1. But I can only change it to a min of 9. I need to know what i should set all the other settings to, to get best performance. I have no idea why it's not working, but it's not :(
For example, this was on a beautiful, sunny day, and I was getting nothing from the solar, as it seems it assumed the batteries were full:
PLEASE! ANY ADVICE IS MOST WELCOME!!!
Many, many thanks!!!
