Marstek CT003 smart meter with P1 and infrared connection, WiFi and Bluetooth
The Marstek CT003 is the smart meter that reads data straight from the household electricity meter and passes it to the Marstek storage system, which then matches charge and discharge power to real consumption in real time. It offers two connection methods: the P1 port or the infrared sensor, both of which can be set up without an electrician and without touching the distribution board.
It is the right tool for anyone with a digital meter offering a P1, IR or TIC interface who wants load balancing and zero grid consumption. It also detects surplus solar energy and tells the battery to store it. Powered over USB Type-C, drawing less than 2 W, it communicates over Wi-Fi and Bluetooth 5.2 with an external antenna for a steadier signal, and can manage several storage units at once. 10-year warranty.
Key features
