5.5kW Inverter "Idle" Load and Temperature
I installed my 5.5kW inverter with two Pylontech UP5000 batteries. I don't have solar at this stage. It's only to provide power during power outages.
I was at first worried about the battery settings but I see the inverter uses the settings as received through the CAN connection which I guess is fine as the battery is communicating with the inverter.
My biggest question at this stage is during "idling" when the grid is on and the inverter is only supposed to pass the grid to the load, it's constantly running around 70 watts with about 20 watts going to the batteries. The inverter is also hot. I would say about 50 degrees celsius. So my questions are (1) why does the inverter charge around 20 - 50W to the batteries when they are full and (2) why is the inverter using about 50 watts and hot when it's not supposed to do anything? Note that I have configured the "grid trickle feed" setting as 0 W.
I understand that the inverter is trying to keep the batteries at maximum charge, but I would prefer for it to charge to 100% and then basically do nothing until the charge drops to below 95%. It is wasting energy and over time it will add up. With solar it makes sense to "trickle charge" but not with grid power which costs a lot of money.
