I have two 5.2kw batteries. The DIP switches have been set and they both charge showing full.
During discharge the second battery , furthest from the inverter , discharges faster than the other.
The App only shows the lowest power battery and when at 4% ,while the other battery still holds 50% charge, it switches to the grid ?
Can anyone advise why this is ?
chadwickcv7 Call support and ask them to have a look. This isn't something that an end user can sort. The advantage of LiFePO4 Cells is that they can discharge at a constant rate and voltage between almost fully charged and almost fully discharged. Unfortunately, this means that the primary indicator of state of charge, the cell voltage, hardly varies. While this is a good thing for performance, it makes it extremely difficult to gauge exactly how much charge is left in the battery. There's no easy fix for this but there should be a solution to batteries not load sharing properly.
Many thanks Tim
The new upcoming firmware is to address this.
I have 3 5.2 packs. All report varying SoC values none match the Inverter one.
