Victron SolarSense 750 – SLS300175100

Victron SolarSense 750 Wireless PV Installation Monitor The Victron SolarSense 750 - SLS300175100 is a fully self-powered, wireless PV installation monitor designed to help you understand, optimise and make better use of the solar energy available from your photovoltaic system. Ideal for off-grid, hybrid and grid-limited solar installations, the SolarSense 750 measures real-time solar irradiance, estimated available PV power and panel temperature. This gives installers, system owners and automation platforms valuable insight into what the solar array could produce, even when actual PV production is reduced because the batteries are already full or the system is limiting export. Make Better Use of Available Solar Power In many off-grid and grid-limited solar systems, excess solar energy can be wasted once the batteries are fully charged. The Victron SolarSense 750 helps identify how much PV power is still available, allowing users or automation systems to switch on additional loads such as water heaters, appliances or other opportunity loads. By using available solar energy at the right time, you can reduce battery discharge later in the day and improve the overall efficiency of your solar power system. Real-Time PV Performance Monitoring The SolarSense 750 provides direct insight into the potential output of your PV array through the VictronConnect App, VRM or Node-RED. It is especially useful for comparing available solar power against actual production, helping you identify shading, panel issues, configuration problems or system performance losses. Key Features Self-powered operation with integrated solar panel Wireless communication using Instant Readout via BLE advertisements Measures solar irradiance to estimate available PV power Monitors panel temperature for better performance insight Works with VictronConnect for easy access to live data Compatible with VRM for system monitoring and performance analysis Node-RED support for automation and advanced energy control Easy mounting directly on PV systems Useful for new PV system design, testing locations and checking panel orientation Available Monitoring Data Irradiance Measures available solar radiation for PV performance estimation Available Power Estimates how much PV power is available from the installation Panel Temperature Helps assess panel operating conditions and performance Daily Min/Max Solar Power Estimated daily minimum and maximum solar power in kW Estimated Daily Yield Estimated solar energy yield in kWh Optimise Solar Panel Configuration The SolarSense 750 can also be used as a practical pilot device when planning or upgrading a PV installation. By testing different locations, panel angles, orientations and seasonal conditions, it helps installers and system designers understand the best possible layout before committing to a full installation. This makes it a valuable tool for pre-sales surveys, off-grid system planning, solar array optimisation and professional PV performance checks. Fully Wireless and Easy to Install The Victron SolarSense 750 is completely cable-free. It powers itself using its integrated solar panel and communicates wirelessly, making installation fast and simple. It is suitable for remote sites, hard-to-reach PV arrays, off-grid systems and locations where additional wiring would be difficult or expensive. Important note: Bluetooth communication range depends on the installation environment. Metal structures, solar panel frames, roofs and other obstructions can reduce BLE range. Typical Applications Off-grid solar power systems Grid-limited PV installations Hybrid solar and battery storage systems Victron Energy monitoring and automation systems Opportunity load control, such as water heating PV array performance checking Pre-sales solar site surveys Solar panel orientation and location testing Why Choose the Victron SolarSense 750? The SolarSense 750 gives clear visibility of potential solar production, not just actual inverter output. This is especially valuable when solar charging is being restricted, batteries are full or power is being curtailed. By seeing the available PV power in real time, users can make smarter energy decisions, improve self-consumption and identify system performance issues faster. For Victron-based installations, the SolarSense 750 is a compact, plug-and-play monitoring device that adds practical intelligence to solar energy management.
