Hive mind- hoping you all can help me solve this mystery issue. System: Magnum double panel with Parallel stacked 2x4448 pae inverters. Classic 150 charge controller wired with an NMEPV 50 (din rail) and NMEPV100 18 - 245 watt solar modules (6x3). (not over powered)
Issue: every morning the 100 amp din rail breaker is tripping. from what I can gather simultaneously the magnum RTR shows the AGS go into error. Re set the breaker and the solar works fine for the rest of the day. Not 100% sure the AGS has worked (under normal operation) at all other than at commissioning and recent testing. Of course on site i cant get it to fail. Tested the AGS by setting start voltage to 48.2 vdc and put the system under load....... voltage drops and generator turned on with no pv-> Batt breaker issue. last visit, chasing one theory, I re routed the battery + from the mnpv100 directly to the battery + terminal as opposed to the battery + bus bar in the inverter panel still didn't solve the problem. I cant figure out if it the classic causing the issue or if it is the inverters and the AGS. Any input would be appreciated.
