What is a Battery Backup System?

A battery backup or a home battery storage stores energy generated from sources like solar panels or the grid. It enables homeowners to save excess energy for later use, such as during power outages or periods of high-energy demand. These systems usually include batteries, inverters, and monitoring systems for efficiently managing energy storage and usage.

How it Works

Charging the Battery:

From Solar Panels: If solar panels are installed, the battery backup system charges the battery using the energy generated by the panels.

 From the Grid: If there are no solar panels or insufficient sunlight, the backup system charges the battery from the grid.

Benefits of Investing in Home Battery Backups

Investing in home battery backup systems offers a range of benefits, including:

Uninterrupted Power Supply

Home battery backups provide a reliable power source during grid outages or emergencies, ensuring essential appliances and devices remain operational.

Cost Savings

You can save on electricity bills by using stored energy during peak demand periods. Many energy providers offer time-of-use pricing plans, meaning electricity costs more during peak periods. Using a whole home battery backup system to store energy during off-peak times and using that stored energy during peak periods can result in significant cost savings.

Environmental Benefits

Using energy stored in a home battery backup system can reduce reliance on the grid and lower your carbon footprint. Storing energy from solar panels or the grid during off-peak periods and using it during peak periods reduces overall energy consumption and environmental impact.

Increased Reliability

Home battery backup systems provide increased reliability and peace of mind, especially in areas prone to power outages. These systems ensure you do not lose power during critical moments like storms or emergencies. Many systems also have monitoring features that alert you if the battery is low or needs maintenance, ensuring a reliable backup power source.

Potential Return on Investment

As energy costs rise, home battery backup systems are becoming more popular. Installing one can be an attractive selling point if you decide to sell your home.

One such manufacturer is Credence Energy, which offers a wide range of home battery backup systems, portable battery generator, and solar battery storage system. When choosing a home battery backup system, you should choose a reputable brand with a proven history of producing reliable and high-quality products.


Backup system costs fluctuate based on type and size. Standby generators are generally pricier compared to UPS and battery backup systems. Nonetheless, the expense of a backup system is usually lower than the cost of downtime and associated expenses incurred during a power outage.

Battery backup systems commonly employ either lead-acid or lithium-ion batteries. Lead-acid batteries are cheaper but have a shorter lifespan, whereas lithium-ion batteries, although pricier, have a longer lifespan.

The battery capacity to power your house varies based on energy usage, household size, and appliances. As a rough estimate, aim for a capacity of 50% to 100% of your daily energy consumption, typically ranging from 10 kWh for smaller, energy-efficient homes to over 20 kWh for larger homes with high energy demands.

Maintenance intervals for a backup system vary depending on its type and size. Adhering to the manufacturer’s guidelines is crucial to uphold system functionality. Routine maintenance aids in identifying and resolving potential issues before they disrupt operations. Typically, standby generators necessitate annual.
