I have a Multiplus II 3000, with 150/45 MPPT, Venux GX and 11,2 Lifepo4 Battery with 3rd party BMS. (PV inverter is a Fronius IG30 without data connection to the GX).
On ESS defs, with "NO grid meter installed", I get system working but the "Critical Loads" not appear:
When Grid Meter Installed is select, the system dont see "any meter" and get this behavior:
Is this config, I get Critical Loads Readings, but not the AC loads, but unfortunately the system go to Passthru Mode (Stop loading and unloading the battery and becomes a museum piece).
I am truly disappointed with Victron. The first Multiplus II came out broken (over temperature error), it was replaced. The Spanish technicians after several attempts of remote configuration can not do the configuration. Last week I had to trade Venus GX because he died at once, forcing the exchange.
I ask for your help to make the installation truly functional. Suggestions?
