August 23, 20224 yr Hi Guys, We had a backup system with a growatt inverter and a pylontech battery. We have recently installed solar panels and put the inverter in Solar or SBU modes. Since installing the panels, the system seems to trip either in the early morning or late evening with a low voltage error. I assume this is due to the panels' inability to provide enough power to run the loads. I understand that the inverter is off-grid, so if the panels can't provide 100% of the load, it switches over to Eskom. I don't understand why the system is tripping. Please can someone guide us on how to fix this issue?

Settings 12 and 13. Not sure about your tripping as it should only switch off on battery cut out but you mention it is actually tripping.
