I have a single phase off grid system on an MPII 5KVA using the SOC generator function to switch via ATS to the distribution network (I don't use it as a generator!!! If the PV is disconnected (SOC) the whole system is connected to the distribution network. "Please don't confuse this with a generator" ). I am satisfied with this solution.
But I would like to increase the 1 phase power from 20A to 40A by parallel wiring and keep the wiring I have (if possible). In the prospect documentation it is written that it is possible to connect up to 6 pieces of MP-II (parallel). Honestly, I'm not quite sure how to connect it :) So maybe you can guide me if I'm doing it right...
Question about connecting two pieces of MPII in parallel (one phase):
a) From MPII (Slave) AC OUT1 I bring the cables to MPII (Master) AC IN, since I do not use the distribution network via victron (we don't have to solve why).
b) Or MPII (Master) AC out I will send the cable to MPII (Slave) AC In - but here I have a feeling that the Master-Slave logic will change :)
How to actually wire it properly???
If I'm not mistaken, I have two options to connect and configure?
1) is a generator where additional MPii are connected from a certain load
2) parallel phasing - this seems like a more reasonable solution to me, but I haven't been able to find out how it works in practice yet.
Regarding the following configuration (ve.config), I found something regarding parallel connection via ve.config. I will document later.
Thanks for advice.
