We have a single 48/5000 multiplus 2, with ESS and 48V lifepo4 battery in a parallel grid connected system. Also 4kw PV direct to grid with an old school grid connected inverter. Currently we use the victron 100A current sensor connected directly to the multiPlus to drive the ESS instead of an ET112 grid meter connected to the Venus OS (raspi).
The system is working great.
I have 2 questions regarding this if anyone can help.
We want to add a second Multiplus. Can we do so still using the current sensor connected to the master only. If so do we just configure the slave in the normal manner but leave the external sensor fitted box 'unchecked' ? - Or do we need to fit a meter (ET112) ?
Because we are running the current set up using the external current sensor the system thinks it sits between the loads and the grid (see photo) and as such throws up a lot of L1 overload messages. I assume I can ignore these as the L1 does not actually pass through the MultiPlus.
Thanks for taking the time to read my post.
