We have an offgrid setup with 2 x multiplus 48/3000/35-16 configured in master and slave. BYD batteries, victron mppt charge controllers.and a color control box
We have an intermittent fault, where the inverters shut down. no error message, no alarms. just show state as off. The frustrating thing is that also intermittently the are other faults but none of which can be reproduced all of which result in loss of power to the house. one scenario is an overload showing when there is no overload, proved by turing off all the power circuits on the house fuse board.
Trhoughout trouble shooting the batteries are either full or charging so the inverters or the mppt are charging the bateries from PV but just not delivering 240v to main board
I have done a full system reset. shut the whole system down except the batteries to no avail. at one point we took the cover off the inverter didnt touch anything and the sytem came on and we had 240v. (with an electrician)
