Looking for many years at these nice blue boxes of Victron and finally having a good reason to buy one or two: two 4,3V European batteries 48V 16S2P LifePO4 batteries from a luxury yacht.
Since I have wired each of my solar panels seperately I am able to make a nice 3x4 configuration that can be connected to the MPPT250/100 that will charge the 48V 8,6kWh battery. BMS will probably be a Batrium.
A Multiplus 2 (FX) will run on mains power and fall back on batteries when the mains are disconnected.
Normally, the Multiplus charges the batteries at will when there is power availabe from the grid.
I, however, want to control the charge of the batteries in order to have a full charge at the end of the day. The stress on the fully charged cells will be for a shorter time before I disconnect the mains to drain the battery till 40%, where the mains is connected back again in the morning.
In this way I can harvest all my solar energy into the batteries and use the solar energy for our household too.
Is there a way to tell the MPPT250/100 or Multiplus at what speed the batteries can be charged?
