Hello,
I have a setup consisting in one battery bank (lithium 3rd party), 2 SmartSolar MPPT´s, 1 Cerbo GX and 2 Multiplus II 5000.
After playing around with the configuration of these multiplus inverters, by configuring them in parallel, split phase or operating as standalone devices (in this case running only one device at a time), I come to a point where one of the multiplus works perfectly fine (in all the configurations above) and the other is behaving very strangely.
Basically the odd multiplus, while charging, presents the charging amout one the Cerbo GX, as a negative load on the ACout, instead of presenting it as a positive load on the ACin.
If checked the wiring, and the shore power is connected to the ACin.
