Marstek CT002 three-phase smart meter 100 A DIN rail with WiFi and Bluetooth
The Marstek CT002 is the smart meter that lets Marstek storage systems read household consumption in real time and adjust battery charging and discharging accordingly. It installs on a DIN rail inside the distribution board and samples power across three phases, but it can also be used on single-phase installations to monitor up to three separate measuring points.
It is the component that enables zero grid feed-in: measuring voltage and current to within 1%, it talks over Wi-Fi or Bluetooth to the Marstek app and to the Venus, Jupiter and Saturn series. The current transformers handle up to 100 A per phase. The compact plastic body takes little space in the panel; installation requires a qualified electrician. 10-year warranty.
Key features
Three-phase samplingIt measures all three phases at once and also works on single-phase installations, with up to three measuring points.
1% accuracyVoltage and current measured to ±1%: storage control stays reliable even with fluctuating loads.
Zero grid feed-inIt gives the Marstek storage system the data it needs to avoid any energy export to the grid.
DIN rail mountingA compact 65.4 × 26.5 × 83 mm body that fits most domestic distribution boards.
