5 kWh Residential ESS

Compact Size / High Efficiency / Easy Installation / High Energy Density

This product is designed to work with an inverter, photovoltaic (PV) system, and related accessories to form a residential energy storage system.

The system stores DC electricity generated by the PV system in the connected battery and, through the inverter, converts battery DC power into AC electricity for use by the household electrical system.

Note: A complete residential ESS may also include equipment such as a distribution box, electricity meter, and other electrical components.


Description

POWER PORTER is a lithium-ion battery designed to store electrical energy and provide DC output. It maintains an electrical connection with the inverter.

Electricity generated by the PV system is managed through the inverter and stored in the connected POWER PORTER. When power is required, the energy stored in the POWER PORTER is converted from DC to AC by the inverter and supplied to the household electrical system to power home appliances.
