Interface meaning on tcl energy storage inverter device

What is the TCL split-type residential energy storage system?

The TCL Split-Type Residential Energy Storage System seamlessly integrates a hybrid inverter and LFP batteries. It satisfies both new installations and retrofitting into existing on-grid systems. The product offers continuous power supply for homes (emergency backup), reduces electricity purchase costs, and leverages peak/off-peak pricing benefits.

How to connect electrochemical energy storage system to electrical network?

To interconnect these systems to the electrical network, it is required to usepower electronic interfaces. Various power electronic converters for the interface between the electrochemical energy storage system and the electrical network have been described. These power converters are divided into standard, multilevel and multiport technology.

What is a multilevel inverter?

In the case of electrochemical energy storage, variations in the storage system voltage with SOC require further overdesign. A more advanced inverter topology is the multilevel inverter. Multilevel inverter topologies enable higher working voltages by splitting voltage stress between multiple semiconductors.

Which standard sets the grid interface requirements for energy storage systems?

The standard that sets the grid interface requirements for a particular energy storage system depends on the point in the system at which the energy storage system is connected. Systems connected at the distribution level are subject to IEEE Standard 15472018 and its companion - testing standard IEEE 152020.

What is a multilevel power converter?

Multilevel power converters can be an important interface for theelectrochemical energy storage systems, since capacitors, batteries, fuel cells or other storage equipments can be used as the multiple DC voltage sources.

What is a power electronic interface?

Generally, a power electronic interface should support interconnection of—and extract the optimal performance from—any storage system regardless of chemistry, manufacturer, or state of health. Systems with different power ratings will require differently rated power converters.
