Swatten Hybrid
Monitors and controls Swatten hybrid inverters and PV storage systems via Modbus TCP.
This template connects Swatten hybrid inverters and all-in-one PV storage systems via Modbus TCP. It reads PV system status and enables active power reduction and battery charge/discharge commands. Compatible with single-phase and three-phase models from 3 kW to 50 kW.

If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Monitor real-time PV system status and inverter operating data on a cloud dashboard for remote oversight.
- Send active power reduction commands to comply with grid operator curtailment requirements.
- Issue battery charge or discharge commands to optimise self-consumption or leverage time-of-use tariffs.
- Create alerts when inverter status indicates a fault or unexpected shutdown.
- Track daily and cumulative solar production across multiple Swatten inverters on a single site.
- Compare performance of single-phase and three-phase Swatten units installed at different customer locations.
Installation
Connect the ModbusCloud Gateway to the same local network as the Swatten inverter via Ethernet.
Ensure Modbus TCP is enabled on the Swatten inverter and note the IP address and TCP port (typically port 502).
Log in to the ModbusCloud platform, add a new device, and select the Swatten Hybrid template from the template library.
Enter the inverter IP address and port in the device configuration and confirm the Modbus unit ID matches the inverter setting.
Verify that PV system status readings appear on the dashboard, then test a control command such as active power reduction to confirm write access.
Things to watch for
The gateway cannot connect to the Swatten inverter over Modbus TCP. What should I check?
Verify that both the gateway and inverter are on the same subnet. Confirm the inverter IP address, TCP port (usually 502), and that no firewall or VLAN rules block the connection.
Which Modbus unit ID should I use?
Swatten inverters typically default to unit ID 1. If you have changed it in the inverter settings, make sure the same value is configured in the ModbusCloud device instance.
Can I control battery charging and discharging remotely?
Yes. The template includes writable registers for battery charge and discharge commands. Ensure the inverter firmware supports remote write operations and that write access is not disabled in the inverter configuration.
Does this template work with all Swatten models listed?
The template supports SIH single-phase, SIH-SL, SIH three-phase, and all-in-one storage systems as listed in the compatible models. If your model is not on the list, the register map may differ and correct operation is not guaranteed.
