General Hardware Configuration
The outdoor-rated systems and Sol-Ark 15K inverters have a “Modbus RS-485” port,
which is not for battery communications.
Sol-Ark 15K
The Sol-Ark 15K inverter communicates with the battery through a single RJ45
port labeled “Battery CANBus.” This port combines the Modbus and CANBus pin
configurations shown below. Both “Modbus RS485” and “Battery CANBus”
ports can do Modbus communication.
The diagram shows the communication board inside the wiring area of the 15K
inverter. Note that only the “Battery CANBus” port is used for battery
communications. The pin configurations for Modbus and CANBus
communication of this RJ45 are listed in the table below.
