1. Solar panels' output voltage are less than 60VDC, which decreases the risk of an electrical fire. 2. One panel would match one MPPT, increasing 5-15% power in production compared to string inverters.  3. Keeping each panel to work individually avoids the impact of partial shadows on the entire solar system. 4. Independently tracking each of the solar panels' production makes it easy to identify each solar panel's performance.  5. Flexible application allows it to switch to off-grid mode to supply AC power to home devices. 6. Lightweight and compact with plug-and-play connectors, it is easy to install. Monitor the running station anytime, anywhere using the app.

BMS300 fluxgate transducer is made of an excitation magnetic ring and a control circuit. Under normal conditions, the control circuit generates a fixed excitation current frequency to alternately place the magnetic core at the maximum saturation point. When the measured current flows, the primary current is measured by detecting the symmetry of the saturation point. The BMS series is suitable for battery monitoring systems that require high accuracy and low offset. It can realize the isolation measurement between the primary current (high voltage) and the secondary current (12V system).
