WHY SHELLY PRO 3EM-3CT63?
Professional Smart Meter
Shelly Pro 3EM-3CT63 reports accumulated energy as well as instantaneous voltage, current, active, and apparent power per phase/channel in real time. It stores data in non-volatile memory that can be retrieved for a period of up to 60 days in 1-minute intervals. It has a real-time clock to keep the correct time if the connection to an SNTP server is lost.

Use cases for your business
Commercial Building Energy Management
For large commercial buildings, Shelly Pro 3EM-3CT63 can monitor energy usage across various floors or departments. This allows facility managers to allocate energy costs more accurately, identify energy wastage, and implement strategies to improve overall energy efficiency.
Factory Energy Monitoring and Optimization
In a manufacturing plant, Shelly Pro 3EM-3CT63 can be used to monitor the energy consumption of heavy machinery across different phases. By tracking real-time usage, you can identify inefficiencies and reduce operational costs by optimizing energy usage during peak and off-peak hours.
Store Energy Management
If you are store owner, you can use Shelly Pro 3EM-3CT63 to monitor the energy consumption of key systems like lighting, HVAC, and refrigeration units. By tracking the power usage of these systems in real-time, store owners can identify when and where energy is being wasted—such as leaving lights on after hours or running HVAC systems inefficiently. This allows for better control over operating costs, helps in reducing energy bills, and supports sustainable business practices by lowering overall energy consumption.
Use Cases for your home
Electric Vehicle (EV) Charging Monitoring
Monitor the energy consumption of your electric vehicle charger in real-time. Shelly Pro 3EM with the 3-phase current transformer (3CT63) can track how much power your EV charger uses, helping you manage and optimize energy consumption, ensuring that your home stays within its energy budget.
Solar Power Management
If your home is equipped with solar panels, Shelly Pro 3EM-3CT63 can measure the energy generated by your solar system, as well as the energy consumed from the grid. This helps in optimizing energy usage, ensuring that you maximize the use of solar energy and reduce dependency on grid power.
Whole-Home Energy Monitoring
Use Shelly Pro 3EM-3CT63 to monitor the energy usage across your entire home. By tracking consumption across all three phases, you can identify which appliances or systems are using the most power, allowing you to make informed decisions to reduce energy costs and improve efficiency.
