SOFAR Solar Hybrid Inverter

Installation

1. 1Connect the ModbusCloud gateway (MCG or MLP series) to the SOFAR Solar Hybrid Inverter RS-485 port using a twisted pair cable with correct A/B polarity.
2. 2Set the inverter Modbus slave address via the inverter display or configuration menu, and note the address for gateway configuration.
3. 3Confirm that the inverter serial communication is set to 9600 baud, 8 data bits, 1 stop bit, no parity, matching the template defaults.
4. 4Import the SOFAR Solar Hybrid Inverter template in the ModbusCloud platform and assign it to the correct gateway and slave address.
5. 5Power on the gateway and verify that live register values such as inverter status and battery SOC appear in the ModbusCloud dashboard.
6. 6If communication drops after extended operation, contact SOFAR support to obtain the firmware version that fixes the known buffer overflow issue.

Things to watch for

01

Modbus communication stops working after a few hours or days. What is wrong?

Some SOFAR firmware versions contain a buffer overflow bug that causes the Modbus interface to freeze. Contact SOFAR support and request the patched firmware. After updating, communication should remain stable.

02

What baud rate and serial settings should I use?

Use 9600 baud, 8 data bits, 1 stop bit, and no parity. These are the default settings for SOFAR Solar hybrid inverters and the template is configured accordingly.

03

Can I control the inverter or change battery charge modes with this template?

No. This template is read-only and does not include any write registers. It monitors values only and does not alter inverter operation.

04

How do I wire the RS-485 connection correctly?

Connect the A (positive) and B (negative) terminals from the inverter RS-485 port to the corresponding terminals on the ModbusCloud gateway. Use shielded twisted pair cable and keep the run under 1000 metres. A 120 ohm termination resistor may be needed if the cable length is long or communication errors occur.
