Solis 5G Hybrid inverter

Installation

1. 1Connect the ModbusCloud gateway (MCG or MLP series) to the same local network as the Solis inverter, or directly to its Ethernet port.
2. 2Enable Modbus TCP on the Solis inverter via the front panel or the SolisCloud configuration interface, and note the IP address and port (default 502).
3. 3Set the Modbus slave address on the inverter, typically 1 by default, and ensure it matches the address configured in the template.
4. 4Import the Solis 5G Hybrid inverter template in the ModbusCloud platform and assign it to your gateway.
5. 5Verify data is flowing by checking a few key registers such as DC1 voltage and battery SOC on the ModbusCloud dashboard.
6. 6If multiple inverters share the network, assign unique Modbus slave addresses to each unit and create a separate template instance per inverter.

Things to watch for

01

Why does battery power show an unexpected value or appear doubled?

Battery power at register 33149 is a 32-bit signed integer (int32), not a 16-bit register. The template handles this automatically. If you have customised the register, make sure the data type is set to int32 and both consecutive registers are read.

02

How do I determine if the battery is charging or discharging?

Battery current direction is provided in a separate register (33135). A value of 0 typically indicates charging, and 1 indicates discharging. Combine this with the battery power register to get a signed power flow value.

03

What baud rate or TCP port should I use?

This template uses Modbus TCP, so baud rate does not apply. The default TCP port on Solis inverters is 502. Ensure no firewall rules block traffic between the gateway and the inverter on that port.

04

Does this template work with single-phase Solis 5G inverters?

This template is built for the three-phase RHI-3P(5-10)K-HVES-5G models. Single-phase models may use a different register map. Check the register addresses before applying this template to a single-phase unit.
