ESS GUIDE

What Is an Energy Storage System (ESS)?

An energy storage system (ESS) stores electricity from solar PV, the grid, or other energy sources and supplies it when demand increases, renewable generation decreases, or backup power is required. A battery energy storage system combines battery modules with a BMS, inverter or power conversion system, monitoring, protection, and other system components to manage energy safely and efficiently.

How Does a Battery Energy Storage System Work?

During charging, electricity is stored in the battery system for later use. When power is required, the stored energy is discharged through the inverter or power conversion system to supply connected loads or support the grid. The BMS monitors battery voltage, temperature, current, and operating conditions, while system controls coordinate charging, discharging, and energy use.

Energy Storage for Residential and Commercial Applications

Residential energy storage can support solar self-consumption, backup power, and greater energy independence. Commercial and industrial energy storage systems can support peak-load management, backup power, microgrids, renewable energy integration, and other site-specific energy requirements. Seplos offers low-voltage and high-voltage ESS platforms for different project scales.

How to Choose the Right Energy Storage System

Start by confirming the required capacity, system voltage, charging and discharging power, inverter compatibility, installation environment, backup requirements, and future expansion needs. For project-specific configurations, Seplos can help review these requirements and recommend a suitable energy storage system.

FAQ

What is the difference between ESS and BESS?

ESS is a broad term for technologies that store energy for later use. BESS specifically refers to battery energy storage systems, where rechargeable batteries are used as the primary storage technology.

The required size depends on energy consumption, backup duration, inverter power, charging and discharging requirements, available solar generation, and the loads that need to be supported.

Compatibility depends on the battery system, BMS, inverter model, and communication protocol. Provide the inverter brand and model before ordering so the configuration can be reviewed.

Low-voltage systems are commonly used for residential and smaller energy storage applications, while high-voltage systems are often selected for higher-power residential, commercial, industrial, and larger-scale projects.

Some energy storage systems support modular capacity expansion, but compatibility depends on the battery platform, BMS, system voltage, inverter, and product configuration. Expansion requirements should be confirmed when the system is selected.
