Parallel Configurations
It is permissible to connect up to 20 Freedom LiTE
’s in parallel provided that the Freedom
LiTE model size used is the same throughout. It is however more cost effective to purchase
one larger Freedom LiTE model than connecting multiple units in parallel. Parallel
installation is usually reserved for future expansion where it is not feasible to purchase a
model large enough upfront (financial constraints).
One LiTE is programmed as the Master, while the rest of the LiTE
’s connected to the DC bus
are programmed as Slaves.
The parallel LiTE
’s
must be connected to each other via the CAN Bus using standard LAN
cable.
Where CAN Bus is used to control the inverter(s) and charge controller(s), the CAN Bus from
any battery can be connected to the inverter directly or the system controller, depending on
the product brand.
This battery is then “daisy chained” to all other batteries in the system.
This is achieved by providing two RJ45 sockets on the battery
–
refer to Figure 5.2. On the
last battery in the chain, one socket is used for an end of line (termination) resistor, and the
other socket for connecting to the next item of equipment, whether it be another battery,
an inverter, a solar charge controller, or system controller.
