This device is excellently suited for use in photovoltaic systems to separate self-consumption from surplus, thus enabling efficient use of solar energy.

The meter is equipped with three current transformers, allowing for precise measurement without interrupting the wiring. The collected data can be visualized via the Shelly app, and thanks to supported protocols such as MQTT and Modbus, the Shelly Pro 3EM can be easily integrated into home automation systems. DRBO Greenenergy recommends it as an ideal complement to their SunLit energy storage systems to achieve optimal energy efficiency.

How does the Shelly Pro 3EM work in a solar system?

The Shelly Pro 3EM simultaneously monitors PV production, household consumption, and grid feed-in using current transformers. Surplus energy is detected and used via the app or API to either charge storage or control consumers. Installation is straightforward and does not require an electrician.

In practice, the meter is installed in the main distribution box. The current transformers are clamped around the phase conductors to measure energy flow in real time. In case of surpluses, a consumer, such as a heat pump, is automatically activated or a storage unit is charged. DRBO Greenenergy offers seamless integration with their SunLit storage units, providing the option of a zero-export strategy to minimize grid feed-in and maximize government subsidies. Users report an increase in self-consumption of 20-30% through precise control of energy flows.

What advantages does the Shelly Pro 3EM offer for photovoltaic operators?

The Shelly Pro 3EM helps increase self-consumption by up to 30%, thereby reducing electricity costs. Thanks to dynamic load control, it is particularly cost-effective, maintenance-free, and easily expandable if required.

Among the main advantages is that the meter provides important data in real time to minimize grid consumption. The Shelly Pro 3EM is compatible with most common inverters and offers easy plug-and-play installation. DRBO Greenenergy emphasizes how well the Shelly Pro 3EM can be used in combination with their SunLit options to benefit from dynamic electricity tariffs. In the long term, the investment pays for itself through savings and qualification for subsidies. The meter is also robustly built (IP50), making it ideal for use in demanding environments.
