Victron SolarSense 750 Wireless Solar Monitor | SLS300175100

The SolarSense 750 is quite simply the smartest way to see exactly how much power your solar panels should be producing without you needing to touch a single wire. It acts as a small, independent reference point for your system, telling you if your panels are working at their best or if they are being held back by shade, dirt or poor positioning. Because it is completely wireless and powers itself using its own tiny solar cell, you can install it in minutes and start seeing real-time data on your phone immediately. It takes the guesswork out of solar power, helping you decide exactly when to run your appliances to make the most of the free energy from the sun.

No wiring required: The unit is completely wireless and cable-free, making it incredibly easy to install in remote or hard-to-reach spots. Powers itself: With its own integrated solar panel and internal battery, you never have to worry about connecting it to a power source or changing batteries. Check from your phone: You can view your solar performance, temperature and energy yield instantly using the VictronConnect app on your smartphone. Stop wasting energy: By knowing exactly how much solar power is available, you can choose the best time to turn on heavy loads like water heaters or chargers. Find the perfect setup: Use it as a trial device to test different locations and angles for your panels before you commit to a permanent installation. Built for the elements: It is fully waterproof and designed to live outside year-round, performing perfectly in everything from freezing winters to scorching summers.

Product Details
The Solar Sense 750 is a sophisticated standalone monitor designed to provide a professional level of insight into any photovoltaic installation. While traditional monitors tell you what your system is currently doing, the SolarSense 750 tells you what it is capable of doing. By measuring solar irradiance and cell temperature, it calculates the "estimated solar power" available, allowing you to see if your main panels are underperforming due to external factors like dust build-up or aging.
Installation is remarkably straightforward. The package includes a mounting bracket with an alignment ledge, two self-drilling screws and a locking screw. You simply attach the bracket to your solar panel frame, slide the sensor into place and tighten it down. The unit is rated to IP65, ensuring it is totally protected against dust and water spray.
Data communication is handled via Bluetooth Low Energy advertisements, which Victron calls Instant Readout. This allows the sensor to send data to your phone or a GX device, such as a Cerbo GX, without a complicated pairing process. The internal memory is impressive, storing 31 days of detailed trends and up to 730 days of historical maximums and minimums. This long-term data is invaluable for understanding how your solar yield changes through the seasons, ensuring you always have the information needed to maintain an efficient and reliable power system.
