Home Full Guide to Solar Battery Storage System

Without somewhere to store the energy generated by solar panels, electricity will only be available for use when the sun is shining. This means that at night when the sun sets, there won’t be power.

However, with a solar battery storage system, energy generated during the day can be stored and used at night. This means that connected houses and or facilities will be immune to power outages.

This article will offer a comprehensive guide on the types, benefits, and components of the solar battery system.

Types of Solar Battery Systems

There are three major types of solar battery systems, which include off-grid, grid-tied, and hybrid systems. They are explained below:


Also referred to as a stand-alone power system (SAPS). An off-grid solar battery system is not connected to the electrical grid and requires battery storage. It uses solar panels to generate electricity, which is used to power the house or facility, and any excess is stored in the battery. 

With the best off-grid solar system, there won’t be power outages even when the grid is down because there is reliable energy storage.

Off-grid solar battery systems are a great option for people who live in remote areas or who want to be independent of the public electrical grid.


Also known as on-grid or grid-feed. This is arguably the most popular and widely used solar battery system by homes and businesses. It’s connected to the public electrical grid and doesn’t have batteries for storage. The solar panels generate electricity, which is first used to power the building, and any excess electricity is sent back to the grid.

Hybrid Systems

A hybrid solar battery system combines the features of off-grid and grid-tied systems. It uses solar panels to generate electricity and any excess electricity is stored in batteries for use when the grid is down. Also, when the stored energy is depleted, the electric grid serves as a backup, allowing for the best experience of both worlds.

Hybrid solar battery systems are a great option for people who live in areas with frequent power outages or are preparing for emergencies.

Benefits of Solar Battery Storage System

The most interesting part of the things you need to know about solar batteries includes the various benefits attached to them. Discussed below are some of the important benefits of batteries for solar panels.

Energy Independence

A solar battery storage system is an important component of a home or business that needs electricity often. It offers independence by storing the excess solar energy generated during the day for use at night or during power outages. It can also serve as an emergency backup during outages, hence offering peace of mind.

Cost Savings and Return on Investment

By harnessing the energy generated by the sun, a lesser amount of money will be spent on energy bills. Even though standard solar panel batteries are valued to cost $12,000 to $22,000 by the US Department of Energy, the reduction in bills makes the investment worthwhile.

In fact, within a few years, money accumulated from the energy bill reduction can amount to the cost of the solar battery storage system.

Environmental Sustainability

It serves as a perfect and renewable way to generate and store energy. Solar battery storage can help you reduce your carbon footprint and contribute to a cleaner and more sustainable environment. With this, less damage will be done to the environment, making it a safer abode.

Components of a Solar Battery Storage System

The solar battery system is mainly composed of three components – the solar panels and inverter connection, the battery storage unit, and the monitoring and control systems. They are discussed below:

Solar Panels and Inverter Connection

Solar panels generate direct current (DC) electricity from sunlight and the inverter converts it to alternating current (AC), which can be used to power all appliances. The inverter is connected to both the solar panels and the battery storage unit. A professional inverter connection regulates the electricity voltage and frequency, ensuring that it’s safe for the facility’s electrical system.

Battery Storage Unit

This is the solar battery storage system component where the excess energy generated by the solar panel is stored for later use.

The battery storage unit includes various parts, such as the Automatic Transfer Switch (ATS) which enables the smooth conversion of the source of power supply from off-grid to on-grid when the battery is low. It also supports a change of source of power to the electric grid when necessary.

Another important part of the battery storage unit is the Battery Energy Storage Systems (BESS) DC Breaker which ensures reliable and safe protection of the electrical components. It isolates the devices to prevent hazards.

Monitoring and Control Systems

This is for regulating and monitoring the function of the solar battery system. The systems provide real-time information about the solar battery system operation, such as the energy consumed by the facility. The control system also allows for the adjustment of the battery settings like the charging and discharging rate.


Solar battery storage serves as an energy storage system to curb power failure and outages. It ensures that the facility’s electricity is retained despite the inconsistencies in the power supply.
