Solved: Dual Multiplus-II with non symetric Output and ESS missing Grid-Setpoint

Hello all,

i have a Problem with 2 MP-II 3000/48/32 in parallel Setup, on Phase L1 in 3 Phase Grid.

EM24 Grid Meter in Place.

ESS is missing the Grid Set Point by at least a few 100 Watts.

Power-Output is not the same on both Inverter,

Maybe 1/3 generated from the older Inverter and 2/3 of Power from the newer Inverter, measured on the AC Side.

Both MP-II 3000 run fine in Single Inverter Configuration with ESS, configured parallel ESS is not usable, same Wires.

Both Devices are the PMP482305010 , the first one bought April 2021 and the new Unit from Feb. 2022.

Firmware on both Inverter is up to date, 497.


The Inverter wnhere bought by different Distributors, which one to contact ?

Kind Regards,

Kai

Switched to 120 deg. Splitphase with 3phase Grid here in Germany, after sorting out Problems with anti-clockwise Rotation of the House Installation. Everything working fine now.


Thanks to Mr. Gaida, for the professional Mail Support.


Best Regards,

Just one question / confirmation: You run a 120° splitphase config with 2 MP2 - basically omitting the 3rd phase, if I understand the solution you pointed at correctly?
