Think of the following scenario:
3-phase ESS based on Multiplus 5000, 14kWh battery, solar (4kWp) & house connected to critical loads.
Winter day, solar power is rare and well below the consumption of the household. No chance to charge the battery the next days with extra PV power.
According to the datasheet the multis have a consumption of 3 x 18W = 54W. Which is quite significant.
Is there a way to tell the multis to do nothing, not charging, not inverting? Basically it should disable the low- and high-side FETs to let the transformer run freely.
Ideally the multi would go into that state by itself.
If this is possible, how high would be the power consumption in that state?
