Growatt GroBoost control unit for water heating

The combination of a GroBoost from Growattand a Solaranlage, you can effectively use the surplus solar energy to heat your hot water buffer tank. This leads to a significant increase in the efficiency of your Solarasystem. Depending on the output of the Solarasystem, it is possible, for example, to heat all the water during the summer months using only the surplus solar energy. The GroBoost enables adjustable output control from 0 to 10.8 kW. It divides the power into three zones, for which three independent power outputs are available. When integrated into the smart home system, the GroBoost can achieve a solar self-consumption rate of up to 92%.

about the GroBoost

Operating modes

Smart mode: The GroBoost will operate according to the set time period and temperature, with 5 groups of adjustable time periods. During Smart mode, the appliance operates at its rated power, but the power output of phase l1 is adjustable.
PV linking mode: The GroBoost can receive a real-time energy flow via the ShineLink system. By setting the execution strategy, it will automatically operate and adjust its output power when a certain power is exported to or imported from the grid to make the best use of solar energy and maximize the self-consumption of solar power. In addition, there is also a thermal protection function to guarantee the water temperature during the set time period and temperature pinch if a grid failure occurs or the solar energy is insufficient.
Forced operation mode: Triggered by manually pressing the button, the GroBoost can be force activated and will continue to run until it reaches the maximum temperature (default temperature is 65°C). This is often used in emergencies. For safety reasons, the maximum duration of forced operation mode is 2 hours as standard.

Growatt Shine monitoring platform

With the ShineLink-X can use the Growatt monitoring platform. This is available as a smartphone app (for iOS and Android) and as a web version. Use of the platform is free of charge. all Growatt products that are owned can be configured and monitored via Shine. It is also possible to display self-consumption and trends.
