3.7 Synchronised parallel operation
Several charge controllers can be synchronised with the CAN interface. This
is achieved by simply interconnecting the chargers with RJ45 UTP cables
(bus terminators needed, see section 3.6).
The paralleled charge controllers must have identical settings (e.g. charge
algorithm). The CAN communication ensures that the controllers will switch
simultaneously from one charge state to another (from bulk charge to
absorption for example). Each unit will (and should) regulate its own
output current, depending a.o. on the output of each PV array and cable
resistance.
In case of synchronized parallel operation, the network icon will blink
every 3 seconds on all paralleled units.
The PV inputs should not be connected in parallel. Each charge
controller must be connected to its own PV array.
3.8 Energy Storage System (ESS)
An Energy Storage System (ESS) is a specific type of power system that
integrates a power grid connection with a Victron Inverter/Charger, Venus-
device and battery system. It stores solar energy into your battery during the
day, for use later on when the sun stops shining.
Please refer to the following manual how to setup an ESS:
