Can the MARSTEK CT003 Smart Meter detect the electricity consumption data of the various devices in my home?
What should I do if my electricity provider does not support smart meters?
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.
