The grid in the Netherlands is reliable enough that i do not need critical/UPS function.
Can I leave the output of the Multiplus 2 GX diconnected when I use it’s ESS function?
Do I need a Victron Energy Meter or is the current sensor enough to see when it is feeding back to grid.
And most important question, will this work?
You say you want to disconnect the MP, but keep using the ESS.
The whole idea of ESS is for it to do it’s thing( as per your settings), which it won’t if its disconnected.
Out of curiosity why do you want to disconnect?
CT clamp as per drawing is sufficient.
Personally i prefer this, i had an energy meter but didn’t like the lag of it, so changed back to CT clamp which i found to be more responsive.
You can do it like this, no problem, it is ESS but partial because you are grid parallel, so you cant use battery or PV power when grid fails
I have a 3ph ESS setup in NL, and my whole house is on it so still power and PV when grid fails, im happy with it had some serious grid fails in the past 2 years…
Ct clamp is fine, energy meter is also fine -but use a fast one for better results
Have you considered a single 10kVA and Cerbo to simplify the install? Otherwise you only require one MP GX as you will have to disconnect the second GX device. Yes you can connect to ACIN only for a parallel system. An ET340 can do both PV inverter and storage system.
Isn’t it able to feedback onto the grid?
What I understood from this video:
Is that it can feedback onto the grid. If for example a machine takes 1,5kw from phase 3, and have the multiplus on phase 1, it is able to feedback the amount of 1,5kw to phase 1, effective allowing your energy meter display " 0 KW".
I do not necessary want to disconnect, I want to be able to feedback so my meter shows 0KW.
I wonder if i can do that with 1 multiplus II GX
