Is the Multiplus-II still in charge of the battery charging profile during grid loss or are the MPPT's?
With a normal ESS system during grid connected operation the MP2 shows the charge states with LED's on the left side (Bulk, Absorption, Float).
During grid loss there is no charge state indication yet both MPPT's show EXT control.
Everything is VE direct connected.
Who is now monitoring charging?
MP2, MPPT's, Smartshunt?
All can have a slightly different voltage readings.
