How can I connect the MARSTEK CT003 with the MARSTEK energy storage system to enable real-time monitoring and data transmission?

First, connect the CT003 Smart Meter to the household meter via the P1 interface or infrared. Then connect the CT003 to the storage system via the app and go into the settings of the storage system in the app to select and configure the CT003. After completing the configuration, the CT003 will start monitoring energy consumption in real-time and transmitting the data to the storage system to enable intelligent management and optimization.

Can the MARSTEK CT003 Smart Meter detect the electricity consumption data of the various devices in my home?

The MARSTEK CT003 intelligent meter is primarily designed for monitoring the total electricity consumption in the household and does not provide a direct function for identifying and distinguishing the electricity consumption of individual devices in the household. If you have higher requirements for monitoring household electricity consumption, we recommend consulting a professional energy service provider to find a suitable solution for your home.

What should I do if my electricity provider does not support smart meters?

You can purchase and install independent smart meters like the MARSTEK CT002, which can be directly connected to the household power grid to monitor electricity consumption in real time. For certain household appliances, you can also use smart plugs to monitor their power consumption. Furthermore, we recommend contacting your energy provider to find out if smart meter services will be offered in the future so that you can upgrade if necessary.

Can the MARSTEK CT003 Smart Meter help balance the three-phase load in my home?

The MARSTEK CT003 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 sufficient to meet the overload demand. We recommend assessing the load of each phase and distributing household appliances accordingly to avoid overload. To solve the problem, you can also consider increasing the storage capacity or implementing more advanced energy management strategies to ensure a balanced three-phase load in your household.
