48V ESS system with one Multi 5000 and BlueSolar MPPT 150/35 needs additional SmartSolar 100/20 charge controller.
Is this a valid configuration?
If you mean to connect the 100/20 to a GX device with VE.Direct cable then yes, that will work.
Make sure that the 100/20 that you have is a 48V version, some older ones were only capable of up to 24V. The 24V version is no longer produced, but it is best to double check.
One more question, please. How controllers will appear on Overview page, as a multiple tiles, one per each controller, or as a single tile with cumulated produced power?
