Victron Energy SolarSense 750 SLS300175100

The Victron Energy SolarSense 750 is an innovative monitoring device designed to provide real-time solar performance data and help optimise energy usage in photovoltaic systems. It enables users and automation systems to better manage available solar power, ensuring that excess energy is used efficiently rather than wasted.

In many off-grid or grid-limited solar systems, once batteries reach full charge, additional solar energy often goes unused. The SolarSense 750 helps identify this available power so it can be redirected to additional loads such as water heaters, appliances or other electrical devices, reducing reliance on stored battery energy later.

The device measures solar irradiance, estimated solar power output, temperature and daily yield, providing accurate real-time insights into system performance. This data can be used to optimise solar energy consumption, improve system efficiency and monitor the overall health of a PV installation.

The SolarSense 750 can also function as a pilot device for solar system planning, allowing installers to evaluate solar performance across different panel orientations, installation locations and seasonal conditions. This information helps determine the most effective solar panel placement and configuration when designing new PV systems.

One of the key advantages of the SolarSense 750 is its fully wireless and self-powered design. The unit includes a built-in solar panel and internal rechargeable battery, eliminating the need for external wiring or power supplies. Communication is achieved through Instant Readout wireless transmission via Bluetooth Low Energy (BLE), allowing quick access to system data.

With an IP65 protection rating, wide operating temperature range and robust housing, the SolarSense 750 is designed for long-term outdoor installation in demanding environments.
