Battery SOH, Today Life Cycles and Total Life Cycles are calculated incorrectly for Deye BOS GM5.1 + BMS HVB750V/100A #350
Comments
Did you set the nominal voltage in the configuration? |
No, i thought it is taken from inverter data as this value is shown in stat. |
What value you have in Device sensor? |
Can you please show me what value you get when you read register number 224 using Developer tools >> ACTIONS >> Solarman: Read Holding Registers (Modbus Function Code 3)? |
What about 255, 10006 and 10048. |
0 |
So it's proly at 100% at all times and thus not measured. |
Description
Hello,
The following sensor values are incorrectly calculated for Deye BOS GM5.1 + BMS HVB750V/100A:
Im not sure whether it is a bug or a feature request (cause maybe noone had a chance to test it with Deye hith voltage batteries).
I have BMS HVB750V/100A + 8 instances of Deye BOS GM5.1 and was wondering why my battery when charging from (lets say from todays example) from SOC 12% till 90% takes 3.37 lifecycles :) and totally 58 days of work already used 142 lifecycles but i change only over night and discharge during the day (excepting sunny days but now it is a winter and it is not too mamy sunny days).
Today i have investigated the code and see that those values are calculated but not taken from inverter/bms/battery statistics.
So seems like there is a bug with those calculations.
Reproduction Steps
Any charge shows wrongly calculated sensor data for:
For example, charging from 12% to 90% takes 3.37 lifecycles.
Log
Not sure they are needed, if so - i will attach later.
