i plan to move to a complete decoupling to the public grid (microgrid/off-grid/island) in a 3-phase configuration. The basic power and battery requirements are known and i could use the Multiplus 48/5000 or the Multiplus II 48/5000 or the Quattro 48/5000 - but which of them is best suited in this mode ? Any special feature at the AC-In line does not matter (there is no public grid) any PV and other genset are connected to the AC-out. Running ESS configs in the past with both Multiplus variants shows that the MultiplusII fans are more or less always running which was not the case with the Multiplus - which is not critical but worth mentioning. Because both Multiplus variants are still on sale, i'm curious to understand the pros and cons for my planned off-grid configuration. Any advise/comment/experience ?
