Hi all,
I have a very simple ESS setup which works as expected under the internal grid meeting.
Multiplus II 5000VA with Cerbo GX + 2x Pylontech US3000C
Everything works well although in order to get the Critical Load function to operate with a grid failure, you must enable an External Meter. Fine:
In my case, I have the official Victron Current sensor 100A:50mA with the jack cut off and wired as per the manual. Please see here: https://community.victronenergy.com/questions/155992/current-sensor-port-on-mp2.html (3.5mm jack was deemed unreliable hence a connector block on new models)
I've verified that the external current sensor is operating correctly because it provides sensible values on a known load. Plus same values as if it were working in the internal current sense.
Anyway, as soon as I switch my Multiplus Grid Meeting from Internal (Inverter/Charger) to External Meter.
Any form of charging and discharging from the Pylontechs fails to happen!
(Unit stays in grid passthrough mode)
Any suggestions on what could be my issue?
Many Thanks!
