Victron Energy SolarSense 750 wireless self-powered PV system monitor

Victron Energy SolarSense 750 — Wireless PV System Monitor

For owners of photovoltaic systems seeking an easy way to monitor yield and installation efficiency, the Victron Energy SolarSense 750 is the ideal solution. This wireless, self-powered monitor eliminates the need for cabling and is particularly well-suited for remote or hard-to-reach locations. Thanks to an integrated solar cell and a 40 mAh / 3.6 V rechargeable battery, it operates effectively even in low-light conditions. With Bluetooth BLE support, it integrates seamlessly with the VictronConnect app for real-time monitoring. Its robust IP65-rated design ensures reliable outdoor operation, even in extreme conditions.

Wireless Operation and Easy Installation

The device is designed for simple installation without the need for wiring. Power is supplied by a solar cell that stores energy in an integrated rechargeable battery. A fully depleted battery recharges within minutes when exposed to sunlight or strong artificial light and can last for over two years in total darkness. Mounting is quick and secure, thanks to the included bracket and screws that attach directly to the PV panel frame.

Precise Measurement and Long-Term Data Storage

The SolarSense 750 measures solar irradiance with a resolution of 0.1 W/m², estimated power output with 1 W precision, and temperature with a resolution of 0.1 °C. It stores data on irradiance, power output, and temperature for 31 days, while retaining historical daily data for up to 730 days, providing valuable insights for long-term trend analysis. This feature is ideal for optimizing energy production under varying conditions.

Integration with the app and other devices

Thanks to Bluetooth BLE support, the device connects easily to the VictronConnect app, allowing you to view real-time and historical data via clear, easy-to-read graphs. The SolarSense 750 is compatible with GX devices running Venus OS v3.60 or later, facilitating integration into a broader energy management system. These connections enable automated consumption control—such as diverting surplus energy to water heating or powering household appliances. ### Technical Specifications
