How to use the energy storage auxiliary switch

What are auxiliary contacts in Enpower?

This may not always be feasible. In these situations, auxiliary contacts in Enpower can be used to disconnect or shed excess solar or heavy loads. In addition, low priority loads with high power requirements may deplete energy storage. Auxiliary contacts can be used to shed these large loads to help maintain energy in the storage system.

How does an energy storage system connect to a power system?

Thus, an essential function for connecting an energy storage system to the power system is the ability to convert between DC and AC. The converter that performs this function is called an inverter

What auxiliary contacts are on the Enpower smart switch?

The figure below illustrates the auxiliary contacts at the bottom of the Enpower smart switch. It also shows the AC combiner, Generator and Encharge lugs. Refer to the Enpower QIG for installation instructions. Note: Use 3/32inch /2 mm flathead screwdriver to work on auxiliary contact terminals.

How ESS can improve the reliability and usage efficiency of energy?

With its energy control and dispatch, ESS can enhance the reliability and usage efficiency of energy. Through the four critical technologies of energy control, energy management, power conversion, and battery management, battery cells, battery systems, and energy storage systems can be easily integrated into energy control applications. like...

Why do energy storage systems need a DC-DC converter?

Using a DC-DC converter to boost voltage allows the energy storage system to be designed with lower nominal voltage. Because lower voltage configurations require fewer series -connected cells, balancing loss and reliability are improved. However, introducing a second power converter also increases cost, complexity, and power conversion losses.

How auxiliary contacts can be changed?

The Ensemble system can change the state of the auxiliary contact based on grid state, generator availability, and battery state of charge. The section describes the different control modes that are supported for solar and load circuits using auxiliary contacts.
