Huawei SUN2000 PV, LUNA2000 battery

Version 1.0 (2025.11.14)

Huawei SUN2000 PV inverters and LUNA2000 battery packs (optional) integration with FIBARO Home Center 3 series and NICE Yubii Home hubs, via the Modbus protocol.

This integration is published in form of encrypted QuickApp device. File attached below is a trial (demo) version that runs for 7 days after installation.
The full version has no time limitation and is distributed as an encrypted QuickApp, released for single FIBARO Home Center or Nice Yubii hub with serial number provided by the buyer.

Cost of full version is 100 Euro without VAT tax (for EU companies with valid EU VAT ID we can use 0% VAT tax for others 23% VAT tax will be applied, so total is 123 Euro to pay).
Cost is per one FIBARO Home Center / NICE Yubii controller.

The integration was tested with Sun2000-10KTL-M1 with Luna2000 10000Wh batteries and DTSU666-H energy meter, and with SUN2000-20KTL-M2 without battery and energy meter connected.

How it works

Huawei SUN2000 inverters support the Modbus TCP protocol, so integration can be started immediately after connecting the device to the home network via a WiFi or LAN cable and enabling Modbus TCP protocol at inverter’s settings.

The connection works locally, without usage of a cloud or the Internet. Data is read in real time, refreshed few times per minute, without limits and delays.

Supported functions

• Readings of the operating status and priorities for energy flow between the PV, energy storage, home load and grid
• Readings of PV power (up to 2 MPPT) and energy 
• Battery status control - charge level (SOC), charging and discharging power, charging/discharging energy, voltage and temperature
• Monitoring of power and energy for home loads
• Monitoring of power and energy for the grid 
• Monitoring voltages for each phase 
• Temperatures provided by the inverter
• Information about inverter operation errors
• Information about off-grid mode
• Possibility to activate one of the action strategies/priorities for energy flow:
  ► Battery First – PV primarily goes to home loads and charges the batteries. When PV energy is not enough for home load, battery is used. System tries to keep 0 energy flow at grid connection.
  ► Sale First– PV and battery cover the home load first, surplus goes to grid. Battery is discharged to the grid.
  ► Grid First – PV energy goes to home load and to grid. When PV energy is not enough, grid covers home load. Battery is preserved - not charged and discharged.
  ► Battery First with grid AC charge – system takes additional power from grid to charge battery with full possible speed.
• Comaptibile with SmartPower energy management for FIBARO

Note: the inverter has a number of additional configuration parameters that affect the operation of above strategies. The parameters can limit the charging/discharging power, specify the minimum battery SOC, limit the maximum power of battery charging from the grid, and many others.

   

QuickApp adds the following set of meters and other child devices to the system:

• Current PV production power [W] (for PV1 and PV2)
• Total energy produced [kWh]
• Current battery charging power [W]
• Current battery discharge power [W]
• Battery state of charge (SOC) [%]
• Minimum required battery SOC – editable value that limits charging/discharging depends on active strategy/priority for energy flow.
• Current home load power [W]
• Export power for grid  [W]
• Import power from grid [W]
• Total energy exported to the grid [kWh]
• Total energy imported from the grid [kWh]
• Inverter temperature
• Off-grid mode binary sensor
• For switches to switch or check energy flow strategy/priority

These child devices can be used in Energy Panel configuration, and in scenes.
