Hi all, I’ve landed here for some advice, hope someone can help!
I have an existing set of renewables at my property, including solar PV, Growatt SP6000 hybrid inverter + batteries (2 x 6.5kW), Zappi, Eddi and Mixergy hot water cylinder.
I’m looking to add a Victron MultiPlus-II 48/5000/70-50 and some Pylon 4.8kWh US5000 batteries to my system.
My question is how easy will it be to add these? Attached is a rough layout of my system.
Will this new kit ‘play nicely’ with my current system, in terms of one trying to charge the other etc (which I wouldn’t want).
It should be straightforward to install it as an ESS. I currently run 3 separate Victron ESS units on the same phase and grid connection. The only modification I needed to make was disabling the chargers on all units at night to prevent them from charging each other. I’m not sure if you can do that with the Growatt - it might try to charge during nighttime hours.
I used Node Red to disable and enable the chargers for my 3 MultiPlus units by simply setting DVCC to 0A.
Apart from that, they load share very evenly. I did not know if it would work, but it is very impressive. I have a single energy meter on the mains input, and they all share the same data from that energy meter.
Would somebody be kind enough to take my schematic above and modify it to include the Victron inverter to show me how it should be connected in?
I think what’s confusing me most is the Victron AC connections, let me explain… my Growatt inverter has a single AC connection that is fed from my 2nd consumer unit. This powers the inverter, and supplies power to my house loads. The victron inverter looks to have several AC connections?
Just put in here assuming there is a ground rod. Put an energy meter on the output of the the smart meter. Assuming you can actually do this based on the electrical codes or laws.
