Good day all,
Kindly requesting any assistance I can get for my system.
I currently have 3 x multiplus II 10kVa running in parallel for a three-phase system.
The system is connected to 3 x RS450/200, pylontech batteries (~340kWh), 1 x Fronius Eco PV inverter (27kW) which is connected on the AC out side and generator which is connected to AC IN on the multiplus inverters (~80kVa).
The system seems to work fine without any AC loads connected. Once the load is connected to the system, the system gives Error 3 & Error 10, works for a few minutes than restarts a couple of times before completely shutting down.
Multiplus ii device firmware was updated to v508 - all devices are now up to date with latest firmware.
The MK-3 update (which was giving #51 warning on the VRM console) was updated.
Here are some of the errors from the alarm logs on 12/01/24 when we had tried to run the system:
This is a newly installed system - Ac cable run is approximately 200m from the inverter/battery room to the generator/ main distribution board room. The PV array is ground mounted with SPDs & 2 pole DC breakers for isolation of each string (isolation boxes mounted on the piles at the array under the panels).
Any advice/help would be much appreciated so I can finally have normal operation of the solar system.
Thanks and much appreciated.
