Communication Ports for Battery Connection

As the demand for clean and reliable energy solutions continues to grow, the compatibility of Solis inverters with batteries from different manufacturers has become a pivotal concern for those seeking versatile and efficient energy storage solutions. In this article, we will delve into the various methods and considerations for seamlessly connecting Solis inverters with batteries from multiple manufacturers, empowering you to tailor your energy storage system to your unique requirements.

If you want to connect your battery with Solis inverters, the communication ports on the inverter side are as follows:

CAN-H (Controller Area Network High) on Pin 4 (blue)

CAN-L (Controller Area Network Low) on Pin 5 (blue/white)

When it comes to understanding the CAN communication details for your batteries, we recommend referring to the individual battery manuals provided by each manufacturer. Different battery manufacturers may have unique specifications and requirements for CAN communication, so it's crucial to consult the specific documentation for the batteries you are using.

We understand that this can be a bit complex, but we have compiled a list of communication connection details for several battery manufacturers to assist you.

Guide for cable connection:

Communication ports: 

• First, connect the enable ground wire to Terminal 2.
• Connect the enable 12V positive line to Terminal 1.
• Select the method that matches the inverter communication method in the part marked. 
• If the inverter uses RS485, connect the RS485 (A+, B-) lines to Terminals 3 and 4. If inverter uses the CAN method, connect the CAN (high, low) lines to Terminals 5 and 6.
