I want to install 3x multiplus 2- 10000 with ESS on a 3-phase configuration. I have have 200 solar panels that are creating 80 amps into 240Volts on all three phases. On other installs I use the AUX2 to shut off the solar panels when there is a power outage. But because the AUX2 on the 10000 is rated 50Amp (I need 80A) I cannot use this.
If I do not use the AUX2 but instead I connect the ESS and Solar inverter in parallel than if a power outage occurs the solar inverter will not shutdown because it will see power from the ESS system. And the ESS system will not shutdown because is sees power from the Solar inverter.
When you are not able to disconnect the solar inverter the ESS manual is stated that you need at least 80Ax240V=19.200 VA of Victron ESS power. But this is not possible.
What options do I have to disconnect the solar panels when there is a power outage?
The solar inverter is not Victron.
