Three-phase Wi-Fi energy consumption monitor - ENERGY 3

Three-phase, 2-way, 4-quadrant electricity consumption monitor.
Perfect for monitoring photovoltaic systems.

ENERGY 3 allows you to record electricity consumption and monitor important network parameters: voltage, current, power, energy consumption. Data access is possible directly from the application or via a web browser.

### Applications

- Monitoring energy consumption in domestic installations;
- Continuous measurement of energy consumption and current and voltage values;
- Using recorded measurements to detect overshoots in voltage levels or energy consumption;
- Controlling energy production in photovoltaic systems;
- Measuring heat pumps.

The unit is supplied with miniaturized, open current transformers. It is not necessary to interfere with the current conductors to attach them to the measurement conductors, but particular attention must be paid to how the conductor is passed through the transformer and the connection of the secondary side of the transformer to the device.
