I bought the two EG4 6500EX and six EG4 LL V2 batteries in the kit offered by Signature Solar in order to get closed communication but despite having read through all of the threads on here and upgrading to the latest firmware for the inverters, I am still getting error 61. I switched setting 5 on the inverters to USE and have been using manual settings to let the inverters manage the batteries that way.
This lead me down a path of figuring out what is the best way to monitor the SOC without having the read the display on the inverters or the battery screens. I found and installed SolarAssistant and it has been working well so far using emulated BMS because I am still unable to connect directly to the batteries (neither on a Windows PC using BMS_Tools (v2.20) or on a Raspberry Pi using SolarAssistant. That is until one day when I decided to check the actual SOC on the battery screens themselves and, to my shock, realized I had actually drained the batteries down to 4% when SolarAssistant was showing around 50% using the emulated BMS. I realize emulated BMS is not very accurate, but I did not expect it to be so vastly different. I am now paying attention to the voltage of the batteries instead.
I have switched SolarAssistant to Use Inverter Settings for battery monitoring. Should I pay more attention to the SOC on the battery screens or is this generally regarded by the community as pretty inaccurate and voltage is what really matters?
