    Sol-Ark’s Battery Partners Sol-Ark has a history of working with many battery companies within the residential market segment. This guide lists the battery companies with whom Sol-Ark has a partnership, though Sol-Ark inverters are battery agnostic and can work with any 48V battery.
  • Page 6 They are well-known suppliers, broadly accessible to installers, and they provide reputable products and domestic customer support. • Though Sol-Ark has experience collaborating with this partner, we have not completed a formal process or service level agreement that would ensure ongoing compatibility or product compliance to safety and regulatory standards.

  • Page 7: General Hardware Configuration

    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-2P-N The Sol-Ark 15K-2P-N inverter communicates with the battery through a single RJ45 port labeled “Battery CANBus”. This port combines the Modbus and CANBus pin configurations shown below.

  • Page 9 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 Sol-Ark 12K / 8K / 5K inverters. Note that only the “Battery CANBus” port is used for battery communications.
  • Page 10 Sol-Ark 12K Legacy (Indoor) The Sol-Ark 12K Indoor can communicate through two RJ-45 ports labeled “CAN” and “RS-485”. Battery communication is established through CANBus or Modbus communication protocols using the “CAN” and “RS-458” ports respectively The diagram shows the communication board inside the 12K Indoor inverter wiring area.
  • Page 11 Sol-Ark 8K Legacy (Indoor) The Sol-Ark 8K Indoor can communicate through two RJ-45 ports labeled “RJ45_485” and “RJ45_CAN”. Battery communication is established through CANBus or Modbus communication protocols through the “RJ45_485” and “RJ45_CAN” ports respectively The following figure shows the communication board inside the wiring area of the 8K Indoor inverter.

  • Page 13 Modbus/RS-485 Battery Screen 2.11. As of Mar 16, 2023, Sol-Ark recommends that if establishing communication via Modbus RS485, be sure to have the inverter firmware upgraded to the latest available version, with Comm v143F or higher, and the latest primary and follower MCU versions.

  • Page 14: Connecting Batteries

    Most custom cables are NOT reversible; therefore, keep track of which end of the custom cable connects to the battery and the Sol-Ark. If you’re crimping new connectors to create a cable, be careful to not over-tighten the crimping tool, as this can recess the connectors and lead to a poor or intermittent connection.
