FAQ
Is the MARSTEK CT002 compatible with the MARSTEK VENUS/JUPITER/SATURN?
Yes, the MARSTEK CT002 is compatible with the MARSTEK VENUS, JUPITER, and SATURN series. The CT002 is a smart meter specifically designed for these energy storage systems. It seamlessly connects to the devices, monitors energy consumption in real-time, and optimizes charging and discharging strategies. By combining these products, users can achieve more efficient energy management, optimize energy consumption and cost control, thus further improving the overall system performance.
How can I connect the MARSTEK CT002 to the MARSTEK energy storage system for real-time monitoring and data transfer?
First, the MARSTEK CT002 should be installed by a professional electrician on the DIN rail of the household distribution box. Then, connect the CT002 to the energy storage system via the app, and go to the settings of the energy storage system in the app to select and configure the CT002. After the configuration is complete, the CT002 will start to monitor energy consumption in real-time and transmit the data to the energy storage system for intelligent management and optimization.
Is the installation and configuration process for the MARSTEK CT002 complicated? Do I need professional assistance?
Be sure to have the MARSTEK CT002 installed by a professional electrician, as opening the power distribution box and wiring work are required. We offer detailed installation instructions and video guides for you and the electrician. You can click here to view them: User Manual and Video Guide.

Can the MARSTEK CT002 Smart Meter help to balance the three-phase load in my home?
The MARSTEK CT002 can monitor the three-phase current in your home in real-time and control the energy storage system to supply additional energy to each phase to balance the three-phase load. However, if the load of one phase is too high, the additional energy from the storage system may not be enough to meet the overload demand. We recommend evaluating the load of each phase and distributing household appliances accordingly to avoid overload. To solve the problem, in addition to optimizing load distribution, you can also consider increasing storage capacity or more advanced energy management strategies to ensure a balanced three-phase load in your home.
