Step 3 – Install the battery-to-battery communication circuit
When installing multiple batteries, it is necessary to use the canbus terminators. This procedure is
different for the eFlex, eVault MAX, and eVault Classic.
eFlex and eVault Classic:
It does not matter which communication port
you plug into on the eVault or eFlex – they are
universal. The canbus terminator looks like a
standard ethernet plug without a cable
attached.
The eFlex uses an RJ45 pinout connector
between the eFlex battery and the battery
inverter.
The eVault Classic does not use RJ45 pinout
converter and can only parallel up to 2 eVaults
when communicating to the inverter.
If not communicating to the inverter, put a
canbus terminator plug on each end of the
communication circuit.
See product manuals for additional detail.
eVault MAX:
The eVault MAX has the canbus terminators
built into the unit. The two eVault MAX units on
the end have the canbus terminators set to ON.
It is does not mattery if the canbus terminator
to ON or OFF when installing one eVault MAX.
The eVault MAX has dedicated a dedicated
port for inverter communication. For the
Sol-Ark inverter, use the RS485 port of the
master eVault MAX.
