ESS Multiplus-2 AC-Coupling: Inverter on AC-Out 2?

Hi!
Is it possible to connect a grid-inverter to AC-Out 2 on the Multiplus?

My idea is to save the EM24 compared to connenct the inverter on AC-In.
(Multi is measuring the currents but kick the inverter out if grid lost)

Yes, you can have a PV inverter on the AC-OUT but I would still have that inverter configured for frequency shift limiting.

All rules still apply.

he is talking about AC-Out "2" not AC-Out1

so, no need for frequency shift MG50 grid code or 1:1 rule.

Its not connected, if Grid fails.


Its basically the same as if it would be connected to AC-in.

Only differences:

- no EM24 needed

- AC-Out2 does come back with some delay time after AC-in.

- And, if coupled to AC-Out 2, you need to consider AC Passthrough power limitations also.
