Hope I have the right section.
My Selectronics SP Pro seems to have bad hair days from time to time where for no reason that I can think of it stops sending power out and instead puts the power into the batteries causing them to go way high and then shut down the system. to make matters worse the sp pro defaults to 85% charge causing the batteries to charge when they are already charged. I try to log in as quick as I can and reset the soc but as quick as I do it the charger raises the voltage again and the cycle begins again. I have reduced the voltage on the charger to stop the voltage rising but it still happens. At the moment I have the system at idle because I put out more power than when it is working. at idle the ac inverter puts out about 2000watts but when the system is running it puts out nothing and instead sends the power to the batteries even though the charger is off. Last time this happened I lowered all voltages so it did not matter if it was in bulk or float it was still low and it seemed to do the trick I also updated the firmware in case that would help and have not had any problems for a few weeks but the problem is back. I hope someone may know why this happens.
