Description
Sungrow iHomeManager Smart Energy Manager
The Sungrow iHomeManager is a smart energy management device for photovoltaic installations with compatible equipment. It uses solar generation forecasts, consumption analysis and local electricity tariffs to plan energy use, increase self-consumption and take advantage of periods with lower electricity costs.
It integrates metering, communication and control functions to coordinate compatible inverters, energy storage and loads. Its built-in meter simplifies installation, while RS485, Ethernet and WLAN connections allow communication to be adapted to the project’s requirements.
Key features
Energy management with AI mode
Plans energy use based on forecast PV generation, consumption and local electricity tariffs.
Built-in metering
Class 1 meter with a specified error of ≤1% and a sampling interval of 50 ms.
Coordination of compatible equipment

Self-consumption management and charging schedules
The iHomeManager combines PV generation forecasts, consumption analysis and local electricity tariffs to plan energy use. Its AI mode is designed to increase the use of lower-cost energy and support renewable energy consumption.
The datasheet also describes an intelligent charging profile based on real-time performance monitoring. Available functions depend on the configuration and compatible equipment connected to the system.
Compatibility and system limits
- Up to 7 supported devices within the configuration specified by the manufacturer.
- A maximum of 5 inverters.
- 1 EV charger.
- 1 heat pump.
- Rated system power of up to 50 kW.
- Energy storage integration through compatible equipment.
Inverters, batteries, the EV charger and heat pump must be selected according to Sungrow’s compatibility requirements and instructions. The availability of a communication interface does not imply compatibility with any device.
Built-in metering and control connections
- Built-in Class 1 meter with a specified error of ≤1%.
- Sampling interval of 50 ms.
- 2 external CT interfaces.
- 4 dry-contact digital inputs.
- 1 digital input for emergency stop via RC short circuit, as described in the datasheet.
- 2 dry-contact digital outputs.
The built-in meter removes the need for a separate meter in the configuration described by the manufacturer. Required current transformers and accessories must be checked for each installation and supplied product reference. Dry-contact outputs are control interfaces; their use must follow the wiring diagram and limits specified in the manual.
Wired and wireless communications
- RS485: 2 independent channels.
- Ethernet: 1 channel at 10/100 Mbps and a communication distance of up to 100 m.
- WLAN: 802.11 b/g/n/ax standards on the 2.4 GHz band.
- Antenna: supports built-in and external options.
- Wired or wireless communication with the inverter, subject to a compatible configuration.
Prediction and precharging for potential outages
The datasheet describes prediction and precharging functions to prepare energy storage for potential outages associated with extreme weather.
The iHomeManager manages the system’s energy preparation. Backup supply during an outage depends on the inverter, battery, electrical installation and compatible configuration. Available runtime depends on stored energy and connected loads.
Power supply, mounting and environmental conditions
- Specified AC input for a 3P3W configuration: 415 V AC line-to-line.
- Specified AC input for a 3P4W configuration: 415 V AC line-to-line and 230 V AC line-to-neutral.
- Power consumption: ≤9 W.
- DIN rail or wall mounting.
- Degree of protection: IP20.
- Operating temperature: −30 to 60 °C.
- Allowable relative humidity: 0–95%, non-condensing.
- Maximum altitude: 4,000 m.
- Dimensions: 108 × 97 × 65 mm.
- Weight: less than 800 g.
- Listed certification: CE.
Install the device in a protected location and in accordance with the manual’s requirements. The power supply and wiring arrangement must be checked for the intended installation.
