SOLIS Inverter and Battery

Installation

1. 1Remove the original Solis datalogger dongle from the inverter communication port before wiring the Modbus connection.
2. 2Connect the Modbus RTU cable from the inverter communication port to the Modbus extension on your ModbusCloud gateway (MCG or MLP series), using the correct RJ45 or JST plug for the Solis inverter.
3. 3Ensure the gateway is configured for Modbus RTU, not RS485 or RS232, since this template requires the Modbus extension.
4. 4Set the correct Modbus slave address and baud rate on the inverter to match the template defaults.
5. 5Import the Solis Inverter and Battery template in the ModbusCloud platform and assign it to the connected gateway.
6. 6Verify live register readings in the ModbusCloud dashboard and confirm that battery charge and discharge values display correctly without modifying the charge-discharge module.

Things to watch for

01

Why do I need to remove the Solis datalogger dongle?

The datalogger dongle occupies the same communication port used for Modbus RTU. It must be unplugged so the gateway can communicate directly with the inverter. After removal, the Solis cloud app will no longer receive data from the inverter.

02

Can I use an RS485 or RS232 extension instead of a Modbus extension?

No. This template requires a Modbus RTU extension on the gateway. A generic RS485 or RS232 interface will not work correctly with this register configuration.

03

Why are my battery charge and discharge values incorrect?

Do not modify any settings in the charge-discharge module of the template. Changing these registers causes incorrect reporting of charge and discharge power. Restore the original template values if they have been altered.

04

Does this template work with other Solis inverter models?

It has been verified on the Solis S5-EH1P6K-L single-phase hybrid inverter. Other Solis hybrid inverters that share the same Modbus register map may also work, but compatibility is not guaranteed.
