10. my-PV Three-phase energy meter
3-phase measuring transformer for my-PV devices. Clamp current transformer for the simplest measurement capture and high installation comfort. Also suitable for large connection capacities in commercial applications. Wireless communication via WLAN. Measurement range: 0 - 75 A (higher currents can be measured with optional clamp transformers). Protection class: IP51. Dimensions: 90.2 x 71 x 57.5 mm. The my-PV Wifi Meter analyzes the current flows of the PV system. It transmits information about surplus power to the router via WLAN. This ensures that only the energy available at the moment is used for heat generation. Therefore, there is no feeding into the power grid: self-consumption of the PV system is maximized, relieving the public low-voltage network. The my-PV Wifi Meter is installed directly after the energy supplier's meter in the distribution cabinet and measures the load flow through three external clamp current transformers. The my-PV WiFi Meter comes standard with integrated 75 A current transformers. The new my-PV WiFi Meter no longer requires an Ethernet cable (LAN) and can be integrated into the home network via WLAN. This offers the advantage that connections from the meter cabinet to the router can now be established wirelessly. To ensure that signals from the meter cabinet, which is usually made of metal, can be transmitted and reach the desired target, an antenna with a 1 m cable is also included as standard. The functionality and view in the my-PV.LIVE Cloud remain the same as with the previous my-PV Power Meter. This offers the advantage that the transition for the customer is barely noticeable. We also see the new my-PV WiFi Meter as a guardian of the current flows of the photovoltaic system, ensuring everything runs optimally.
