I have the dynes bx51100 batteries connected in parralel, the comms is correctly configured... i have managed to get it working by changing the master dipswitch to 3 and not like the booklet states as 3&4. Slave battery should all be 0.
Every night now from midnight it charges by importing from the grid untill 04h00, should this be neccesary? What percentage can i let the batteries go down to without damaging them as I would actually like to charge by solar only as set on the inverter on menu 14, but it still imports from grid
