I see many discussions using Gx or Venus. Are these guys a "must have" to be able to run Multi II with US2000 batteries ? I only have the MK3, I was told this is enough.
-Multi II version 5010
-A set of 3 US2000 batteries
-18 PV x300Wp, so 5400Wp on the roof including APSSystems YC600 micro inverters
-Multi II AC in : Grid connected wtih the loads
-Multi II ACout1 : PV panels including the micro inverters (so out in 220C ac)
-Multi II ACout2 : empty
Using the VE config and setting up the ESS assistant, the Multi II has initially started in Inverter mode then after 1 min delay in "Mains On", while the sun was down and batteries fully loaded.
So I guess it started to use the batteries to feed the power but as there was no com, it stops.
Can you please confirm my assumptions ? or explain the reasons why I can not today feed the loads from the energy stored in the batteries?
Any workaround ?
