Multiple Function IntegrationThis is a two-way solar energy meter with overvoltage, undervoltage and overcurrent protection, which is remotely monitored through the Graffiti system and APP. It covers timer, surge protector, circuit breaker, meter, thermostat, remote switch, voltmeter, ammeter, contactor, thermal relay and power meter. WiFi Smart Circuit Breaker: Connect the device under WiFi status, control it with your mobile phone within an unlimited distance, display power, current, voltage and leakage in real time. Wifi Smart Circuit Breaker's prepayment function allows you to monitor and save money on your electricity bill. LCD Digital Electricity MeterThe smart energy meter adopts a central LCD display design, which can display data with high accuracy and clarity, day or night. The transparent top cover design makes it easy to observe the operation of electronic components. Bidirectional photovoltaic measurement An electric energy meter with bidirectional measurement function, used to measure the electric energy generated by the solar power generation system and the electric energy supplied to the grid, can accurately measure the back and forth flow of electric energy. Installation The bidirectional solar energy meter is installed on the universal standard DIN35mm guide rail, which is small in size, light in weight, simple and convenient to install, and has high reliability. Application Intelligent circuit breaker timers are suitable for most scenarios with DIN rails and are widely used in solar photovoltaic power generation systems, energy metering systems, commercial buildings, apartments, schools, hotel laboratories and other places.
