Hi,
I Have 3 Multiplus II 5000 in 3 phase configuration with Pylontech US3000C Batteries. There is an old AC (in) side coupled Solar system and an a new DC Coupled with two Victron MPPTs. For legal reasons, Im not allowed to feed to the grid with the Victron system (Zero feed in). But the old Solar system is allowed to feed in.
ESS normally works as expected.
In the Morning the Batteries Charge with the chargers in the Multiplus and the MPTTS. When the Batteries are full, the old AC Solar system feed to the grid and the new Victron MPPTs go down to Zero. This happens at around launch time.
Because there is more than enough solar to charge the Batteries with the DC MPPTs, my intend was/is to disable the chargers in the multiplus and allow the old solar system to feed the grid starting in the morning. So I go to the settings -> “Virtual Switch” (Umschalter) -> and to “Inverter only” (Nur Wechselrichter). First everything looked good, the chargers disable and loading only happen with the MPPTs. But then the Problem: The Inverters/ESS do not feed anything in the evening. Its like the whole Inverters are just off and also not providing energy.
So I think this is a bug in ESS?
How to disable the chargers and keep the rest of the ESS functionality active?
I Thought this is “ESS Mode 2” where I can override this settings as described here:

Or is it necessary to enable this “ESS Mode 2” somewhere?
