Backup inverter

A backup inverter is an electronic device that converts direct current (DC) from batteries into alternating current (AC), which is used to power electrical equipment during power outages. This inverter is a key component of uninterruptible power supply (UPS) systems and backup power systems.

Backup inverters are essential for systems where continuous operation is critical, such as servers, data centers, medical facilities, and other critical infrastructures.

Backup power source

A backup power source is a device that provides temporary power to electrical devices during power blackouts. These sources ensure that critical systems and equipment can continue operating without interruption in the event of unexpected power failures.

The most commonly used types of backup power sources include:

Battery backup systems (UPS): Provide immediate power from batteries during outages.
Generators: Used for long-term backup and can be diesel, gasoline, or gas-powered.
Solar backup systems: Utilize solar energy to power equipment during blackouts.

Backup power sources are crucial for the operation of hospitals, data centers, industrial enterprises, and other critical infrastructures where uninterrupted power supply is essential.

Balance group

A balance group is an organized group of consumers, producers, and other participants in the electricity market managed by a single balancing entity. The goal of the balancing group is to optimize the consumption and production of electricity and minimize deviations between the planned and actual supply or consumption of electricity. The balancing entity is responsible for settling these deviations and handling the financial settlement within the group.

Battery management system (BMS)

A Battery Management System (BMS) is an intelligent battery management system that ensures the optimal performance of battery storage systems. The BMS monitors and manages the state of individual battery cells to ensure their safe and efficient operation.

The main functions of a BMS include:

Monitoring: Tracks the voltage, current, and temperature of each battery cell to ensure optimal operating conditions.
Protection: Protects batteries from overcharging, undercharging, overheating, and other potentially hazardous conditions.
Balancing: Ensures charge balancing between individual cells, which extends battery lifespan and improves performance.
Communication: Provides online information about the battery status and communicates with other systems, such as control units or energy management systems.

A BMS is an essential component of modern battery storage systems as it enhances their safety, reliability, and efficiency. It is used in various applications, including electric vehicles, solar systems, and industrial battery storage systems.

Battery storage

Battery storage, often referred to as large-capacity battery storage, accumulator storage or battery energy storage system (BESS), is device used to store electrical energy produced anywhere including from renewable sources such as solar panels. Stored energy can then be used when renewable sources are not available to produce electricity. In the case of solar energy, in the morning or evening hours for example.

An advanced type of battery storage is smart battery storage. Such storage is equipped with advanced technology to manage and optimize its performance and efficiency. These systems include intelligent software platforms to manage the charging and discharging of batteries based on current energy demand, energy prices or the state of the power grid.
