I have had consistent issues with my site.
I have a 5kw Multi Plus and There is 5kw of PV DC coupled through a smart solar charge controller 250/85
I also have 5kw PV on a Fronius , grid connected (line side of the multi plus) and it works fine, and is picked up on the colour control.
Its all on the VRM Portal
Overload is the most common fault, however battery temp sensor error has also occurred.
I have 24 Narada 1000Ah 2volt batteries
Due to the irregularity of the overloads, I have installed a bypass switch which now feeds my house load from the grid and not from the victron / battery system. (My intention is to use my battery power at night and feed any excess power to the grid during the day)
Today it went out on overload, however there was no load on the system.
-0.7A DC, 55.32vDC, 3wAC power.
I have high AC street voltage, which got up to 259vac earlier, but it was only 245v when it overloaded.
At the same minute as the overload the System PV Yield 2.30kw to 3.897kw. does this give any clues?
Thanks
Thomas
