Dear all,
i have an ESS with a single Multiplus II and zero-feedin over all 3 phases. Battery is a 10kWh stack of Pylontechs. Works great but for several reasons i would like to add another Multiplus II for the second phase.
The following questions come up while i'm planning. Thanks for expertise to help me think through it, especially understand how it would work "togehter".
# Regarding configuration. As my Multiplus does also the charging of the battery (not via 48V MPPT charger!!!), how would the two Multiplus coordinate the charging. Like of now L1 provides 35A maximum, would then be the charging load split up 50% 50%...so L1 would be 35/2 A and L2 woudl also have the same 35/2 A. Does the VenusController know that its two Multiplus and organize it by itself??
# In terms of Zero-FeedIn.....if e.g. a load is on L1...of course L1 Multiplus would compensate. The same would happen for L2 (i guess). But how would it work for L3, who of the two would provide the compensation.......or in general both phases would compensate whateve comes in.
Like if L1 = 500W load .........at night L1 from Multiplus would provide 250W and L2 would also provide 250W....
Thanks a lot,
Norbert
