In Installed a Multi II 5000 GX.
The supply is split upstream of the source between essential and non essential. So the inverter has no way of sensing the load of the non essentials without an energy meter or current sensor.
I would like the system to use solar power and stored energy to power the essential and non essential loads to maximise the saving. So I installed the Current Transformer for Multiplus II - 100A on the main supply to the property, thus measuring incoming power to the inverter and to the non essential loads. The inverter now shows this measure as the critical loads as if coming out of AC1 out. So switching on the hot water element causes the inverter to shut down and go into protection mode, although non of that power is going through the inverter.
It would make sense thought to have solar power and even stored power benefit the user by providing as much power as possible to zero this point before grid feeding.
My biggest issue at this stage is that the inverter shuts down based on non essential load.
This installation is with all Victron components, but the next site will be the same but with a solar edge AC coupled inverter.
Thanks
