# Sungrow

Sungrow is a global leader in solar inverter and energy storage solutions.

Within our EMS, we support a wide range of Sungrow inverters for monitoring, control, and energy management.

The following Sungrow devices are compatible with and supported by our EMS for communication and integration.

### Physical connection

### Network configuration

#### Ethernet configuration

To configure the inverter for Ethernet communication:

1. Open the inverter display interface
2. Navigate to:
   * **Settings → Communication Parameters**
3. Enable **MODBUS-TCP**
4. Set the communication port:
   * **Default Port: 502**
5. Configure:
   * DHCP, or
   * A static IP address depending on your network requirements

***

### Device configuration

#### Enable Modbus communication

1. Open the inverter LCD display
2. Navigate to:
   * **Settings → Communication Parameters**
3. Configure the following settings:

| Parameter      | Value                        |
| -------------- | ---------------------------- |
| Protocol       | MODBUS                       |
| Device Address | Unique address between 1–247 |

### Modbus TCP Settings

| Parameter  | Value                              |
| ---------- | ---------------------------------- |
| MODBUS-TCP | Enabled                            |
| Port       | 502 (default)                      |
| IP Address | According to network configuration |

### Known issues

#### Inverter goes offline after receiving a setpoint of 0

Some Sungrow inverter models stop communicating with the EMS for an extended period after the EMS sends a power setpoint of 0 kW (for example, during curtailment at negative energy prices). The inverter enters a low-power or sleep state and does not immediately respond to new commands.

**Workaround**: If this behaviour occurs on your installation, contact Voltmasters Support. A configuration adjustment may be required to prevent the inverter from entering this unresponsive state during zero-setpoint periods.
