Multiplus II + Multiplus

Hello
I get error 25 when connected together MULTIPLUS II and Multiplus.
Multiplus II - 2629 v522
Multiplus - 2673 v522
What can i do?

Hi how are you connecting them together?

You are trying to connect a 1600VA and 3000VA in parallel?
Systems must be of same size “All units in one system must be the same type and firmware version; this includes same size, system voltage, and feature set.”

I solved the problem. I connected the Multiplus II via VE.Bus directly to the Ekrano, and the Multiplus via MK3-USB. Previously, I connected both directly to the VE.Bus.
