LOAD BALANCING

It is possible to connect up to 4 Solar Box modules to each other and let them
share one mains supply.
Software configuration
Configure the Solar Box units load balancing option (LOADBL) and set one
module to MASTER, the others to SLAVE 1, 2, 3. Make sure there is only one
Master, and the Slave numbers are unique.
Example: for a two units Load Balancing setup, set the first module to Master and
the second to Slave 1.
On the Master configure the following:
Set this Smart if a sensorbox with CT's is used to measure the
MODE
current draw on the mains supply. It will then dynamically
change the charge current for all connected EV's. If you are
using a dedicated mains supply for the EV's you can leave this
set to Normal.
MAINS Set this to the capacity of the mains supply.
CIRCUIT Set this to maximum current of the circuit. This will be the
maximum current all EV's combined will use.
MAX Set the maximum charging current for the EV connected to this
Solar Box.
MIN Set to the lowest allowable charging current for all connected
EV's.
