We got a Master/Slave 3-phase Multiplus system - the "mains on" and "float" are blinking (switch position 1). Could not find any hint on the forum nor in the Toolkit app.
We got a solar system connected and throughout there had been Victron products used, even down to the fuses. It is a home (not boat) installation. Accumulators are LiFePo and precharged to about 75%.
On the solar system an additional second Victron energy meter EM24 3-phase had been added for flawless communication (orange). The Victron VM-3P75CT is part of the system as a gridmeter (red) connects via the Can-Bus. Can-bus is terminated of course. 4446W are given to the grid right now.
