Combine with WPC3700 for a Smart Solar PV Heater System

The WEM3050T can be paired with the WPC3700 Wi-Fi power controller to create a complete solar PV heater control system. This solution intelligently uses excess solar power to heat water, increasing self-consumption and reducing energy export losses. It is especially useful in households looking to maximize solar energy usage without adding batteries. The system dynamically adjusts power delivery based on real-time solar surplus measurements, helping customers optimize solar utilization and reduce energy bills.
