Store More of Your Solar Energy and Reduce Electricity Bills
On-grid battery storage systems allow homeowners and businesses to store excess electricity generated by solar panels and use it when energy is needed most.
Instead of exporting surplus electricity to the grid during the day, battery storage captures and stores that energy for use during the evening, overnight or at times when electricity prices are higher.
At Dragons Breath Solar, we supply a wide range of grid-connected battery storage systems from leading manufacturers including Sunsynk, Growatt, Huawei, Fox, Solax, BYD, LG Energy Solution and other trusted brands.
Whether you are installing a new solar PV system or upgrading an existing one, battery storage can help maximise your return on investment while increasing energy independence.
What Is On-Grid Battery Storage?
An on-grid battery storage system works alongside your existing electricity supply.
When your solar panels generate more electricity than your property is using, the excess energy is stored within a battery system instead of being exported immediately to the grid.
The stored electricity can then be used:
During the evening
Overnight
During periods of high electricity demand
During peak electricity tariff periods
As backup power with selected systems
This helps reduce imported electricity and increases the amount of solar energy consumed within the property.
Benefits of On-Grid Battery Storage
Lower Electricity Bills
By storing surplus solar energy and using it later, homeowners can significantly reduce electricity purchased from the grid.
Maximise Solar Self-Consumption
Without battery storage, excess solar energy is often exported during the day when demand within the property is low.
Battery storage allows more of that energy to be used directly by the homeowner.
Protection Against Rising Energy Costs
As electricity prices continue to increase, storing your own energy becomes increasingly valuable.
Smart Energy Management
Modern battery systems can intelligently charge and discharge based on solar generation, household demand and electricity tariffs.
Backup Power Capability
Certain battery and inverter combinations provide backup power during grid outages, helping maintain essential circuits and appliances.
Is Battery Storage Worth It?
For many households the answer is yes.
Battery storage can improve the financial performance of a solar PV system by increasing self-consumption and reducing reliance on imported electricity.
The greatest benefits are often achieved by:
Homes with solar panels
Properties with high evening energy use
Customers on time-of-use electricity tariffs
Homes seeking greater energy independence
Adding Battery Storage to an Existing Solar System
Many homeowners already have solar panels installed but do not have battery storage.
In most cases, battery systems can be added later through either:
AC-Coupled Battery Systems
Ideal for retrofitting existing solar installations.
Benefits include:
Easier integration
Minimal disruption
Works with many existing inverter systems
Hybrid Inverter Systems
Suitable for new installations or major upgrades.
Benefits include:
High efficiency
Integrated control
Future expansion options
Choosing the Right Battery Storage System
Several factors influence the best battery solution for your property.
Daily Electricity Usage
Higher energy consumption generally requires greater storage capacity.
Solar Generation
Battery size should complement the output of your solar array.
Backup Power Requirements
Some customers prioritise energy savings while others require emergency power capability.
Future Expansion
Many modern battery systems can be expanded as household energy needs grow.
Popular Battery Storage Brands
Sunsynk Battery Storage
Sunsynk systems offer flexible expansion, advanced monitoring and excellent compatibility with hybrid inverter technology.
Growatt Battery Systems
Growatt batteries provide cost-effective energy storage solutions suitable for many residential installations.
Huawei Battery Storage
Huawei Luna systems combine modular design with intelligent energy management.
BYD Battery Storage
BYD batteries are widely respected for safety, reliability and scalability.
LG Energy Solution
LG battery systems have been trusted by homeowners worldwide for residential energy storage applications.
What Size Battery Do I Need?
As a general guide:
Property Type
Typical Battery Size
Small household
5kWh
Average family home
8kWh–10kWh
Larger home
10kWh–15kWh
High energy usage
15kWh–20kWh+
The ideal capacity depends on energy consumption patterns, solar generation and future requirements.

Frequently Asked Questions
Can I add a battery to my existing solar panels?
Yes. Many battery storage systems can be added to existing solar installations using AC-coupled or hybrid solutions.
How long do solar batteries last?
Modern lithium battery systems are designed to provide thousands of charge cycles and many years of service.
Will a battery work during a power cut?
Some battery and inverter combinations offer backup power functionality. The exact capability depends on system design.
How much battery storage do I need?
Battery size depends on household electricity consumption, solar generation and how much stored energy you wish to use each day.
Can battery storage reduce my electricity bills?
Yes. Battery storage allows homeowners to use more of their own solar energy and purchase less electricity from the grid.
Is battery storage suitable without solar panels?
Yes. Some battery systems can charge from the grid during low-cost tariff periods and discharge when electricity prices are higher.

When you are considering important questions about the amount of storage this type of battery requires. Home battery storage, maybe you just want to put the excess energy generated during the day into a storage bank for use later. You may want
to be autonomous; everything you ask has an explanation. So it is important to
ask the correct questions regarding the cost of solar panel battery storage
devices.
Battery Storage Solutions
Let us help you understand the benefits of choosing wisely, determining the best battery storage option for your system is very important for existing installations as well as new.
Excess power from solar panels can be put into the on-grid battery storage. If you are interested in PV storage battery cost, or if you want to know how much money it would cost for an on grid home solar battery system. For further details regarding your project
