An Energy Management System (EMS) manages and optimizes the energy needs of your property. The EMS is an external system that sends control signals to the inverter, allowing it to manage the battery and if needed, other appliances in your home. EMS systems often consist of both hardware and software.
The software is typically complex, featuring optimization algorithms, connections to the electricity market (e.g., NordPool), weather data, consumption data, and more. EMS systems may also connect to external platforms, including aggregators, to participate in support service and flexibility markets. The EMS overrides the inverter’s internal control system and assumes full management of the battery’s operation.
With an EMS, the functionality and benefits of your qapasity battery are significantly enhanced. During development, we ensured broad compatibility so that you can maximize your system’s potential.
An Autonomous System
This means the EMS algorithm works on your behalf to optimize based on factors such as electricity prices, time of day, grid tariffs, and more. The algorithm will always prioritize what is most economically advantageous for you, requiring no manual intervention to maximize your usage. System monitoring and energy flow management are also fully automated.
Key Features of an EMS:
Peak Load Shaving:
Energy usage is monitored in real-time, allowing the system to dynamically prevent peak loads by using stored battery energy and controlling other loads. This can reduce grid fees and lower electricity costs.
Electricity Price Optimization:
Through active energy trading, similar to stock trading, electricity is purchased based on hourly prices from the NordPool exchange. This strategy minimizes energy costs by reducing consumption when prices are high and increasing it when prices are low.
Tariff Optimization:
Grid fees can be automatically reduced by optimizing energy consumption to occur outside of tariff periods. The EMS handles this without compromising comfort in your property.
Weather Optimization:
The EMS uses weather data to avoid the need for manual adjustments. You no longer need to plan or make decisions about electricity usage based on upcoming weather. This function, like the others, enhances the efficient use of energy, leading to improved financial results.
Conclusion
qapasity’s system is compatible with several different EMS platforms. The inverter serves as the integration point between the EMS and qapasity’s battery. Therefore, if your EMS system is compatible with a qapasity-compatible inverter, full compatibility is achieved. qapasity’s preferred inverter is Solis, which is compatible with both Enequi and Checkwatt EMS platforms.
