I have a hybrid inverter and three 5kWh batteries. Every night the batteries are scheduled to charge to 100% and they power the house for the rest of the day. Recently I have been seeing a pause in charging on one of the batteries. See this image from Home Assistant.
I was wondering if this was a temperature related pause. Temperature of that battery over the same period was:
Is there some charging cut-off when the temperature exceeds 35 degrees? Should i be managing things differently or is this all normal and harmless behaviour. Any insights welcome.
Reviewing what I wrote, I think it is that the battery has stopped reporting the State of Charge (SOC) to home assistant. Maybe waiting to cool down?
35 degrees is not particularly excessive for the battery, it gets hotter when its charging or discharging. Mine has been to 41.4 degrees today with no obvious adverse problems
I don’t see any pause in charging on your battery SoC chart, it charges to full, is used in the morning, then stays more or less flat until presumably evening, then drops down to midnight then is recharged back to 100%
there are some drops to zero of the reported SoC, that could be a comms issue in givtcp talking to the inverter (check the logs), or maybe a loose data cable on the battery to battery connection?
