Hi everyone
My system is a 3 phase multiplus 5000 and a mppt 450 and two batteries with in sum 30kwh on the AC side is a 3phase fronius 8.3.2.
As i have a mppt450 to load the batterie i set most of time the charger of multiplus 5000 on only Inverter. So the mppt loads the batterie and the fronius supplys the house loads. BUT if the loads are higher as the delivery from the fronius the multi dont invert to supply the house loads.
If i then set the multi on all works fine. But then he also loads the batterie if the fronius has higher output as the house loads are.
What must i do to has the normal installation i want to have. If sun is shining the mppt dont load the batterie, as they would be loadet from the mppt. And if the fronius dont supply the house loads (in the night) the mppt discharge the batterie to supply the house loads.
Sorry for my bad english.
Stefan
