Sol-Ark Inverters in this Guide This document covers battery integration with the following Sol-Ark low-voltage hybrid inverters: • Sol-Ark 15K (Indoor/Outdoor) • Sol-Ark 12K (Outdoor) • Sol-Ark 12K (Indoor) • Sol-Ark 8K (Outdoor) • Sol-Ark 5K (Outdoor) Latest Firmware For Modbus RS-485 communication reliability, update to the latest firmware version, with C 1.4.3.F or greater.
This Guide is intended to specifically list batteries that have been certified to work with Sol-Ark hybrid inverters as the Effective Date. If not listed, the battery has not been certified to work with Sol-Ark hybrid inverters, or tested by Sol-Ark, but Sol-Ark inverters are designed to be battery agnostic and are generally intended to function with most 48V batteries.

Modbus/RS-485 Battery Screen 2.11. 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. The image shows the “Li Batt Info” screen when communicating via Modbus/RS-485 (all other “BMS Lithium Batt”...
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 not to over-tighten the crimping tool, as this can recess the connectors and lead to a poor or intermittent connection.
Certified Storage Partners This section includes the battery manufacturers that Sol-Ark has certified to work with our inverters as of the Effective Date and the compatible battery model. Modifications, updates, or other changes made by the battery manufacturer to a battery product, including...
