Multiplus II 5000 Parallel single Fase

Good morning everyone,

I installed two MPII 5000 inverters in L1 single phase parallel configuration. In node-red I can query the individual units and I have verified that between them there is always a delta in favor of the Slave of a percentage between 10% and 19%. (Firmware is the same). I wanted to ask anyone who has experience if it is an acceptable delta that will not cause problems. The same thing also on ACin (grid) in input when active.

Thanks in advance for your response.

You should be able to get them under 10%, or less. It will never be perfect, but that seems a bit high.

How, exactly are you pulling the individual stats?

Hi, I simply use the node-red library "mqttin" with the address "N/cxxxxxxxxxxx/vebus/275/Devices/0/Ac/Out/P" and "N/cxxxxxxxxxxx/vebus/275/Devices/3 /Ac/Out/P", this in my case.
