I have a hybrid system with a Steca AC invertor and a Multiplus II Victron invertor.
Completely off grid
I had Pylontech batteries for 7 years which was replaced 3 months ago with BSL3ATT bateries with exact same KWH rating as the Pylontech system had.(19,2KWH)
Ever since the replacement 2 problems occur.
1. I get VE.Bus overload L1 warnings every so often, sometimes when a pressure, borehole or pool pump starts, sometimes with almost no load at all. All my pumps are on timers so that max load can never go above 4kw
2. The bigger problem, the moment the batteries gets fully charged, the Victron trips/switches off which also switches the Steca off, Victronb restarts after a few seconds, as soon as it is on the Steca starts booting up. As soon as the Steca starts up it trips the Victron again. This happens even if I switch my mains off - no load at all. Only way to get passed it is to switch the panels connected to the Steca off and only run the Victron. Ocassionally this will repeat itself 4-6 times and then the system will get up and run again. More often I have to switch the Steca panels off.
I am worried about damage to the invertors or batteries
Any ideas?
