On-Grid Solar and Battery Systems
Battery Storage Systems, Hybrid Systems, Solar Batteries, and Energy Storage Systems (ESS) are designed to give your home greater energy independence and control beyond solar alone. Systems range from smaller batteries for storing excess solar power to larger solutions capable of powering your entire property off-grid.

What level of energy freedom fits you?
Start with your budget
An accessible starting point for battery storage, helping you make better use of your solar energy and reduce electricity bills, with future expansion considered where practical.
What we'd consider in your design: Budget, available solar surplus, household consumption and expansion potential.
Make more of your solar
Capture more of your surplus daytime solar energy for use in the evening and overnight, with storage sized to balance savings and investment.
What we'd consider in your design: Solar exports, evening demand, battery capacity and financial return.
Aim for minimal bills
Take your energy savings further with solar and battery storage designed to minimise, or potentially offset, your annual electricity costs.
What we'd consider in your design: Annual consumption, solar generation, electricity tariffs and storage requirements.
Keep your home powered
Enjoy greater independence from the grid, with backup power designed around your household's needs, including whole-home protection where practical.
What we'd consider in your design: Energy self-sufficiency, backup power capacity, essential loads and outage duration.
Build towards independence
Start with a grid-connected system designed for future off-grid operation, allowing solar and storage capacity to be expanded as your needs or budget evolve.
What we'd consider in your design: Inverter architecture, future expansion, generator compatibility and off-grid requirements.
Disconnect completely
Leave the electricity grid behind with a fully engineered standalone power system designed to reliably meet your property's year-round energy needs.
What we'd consider in your design: Year-round energy demand, winter solar performance, battery autonomy and backup generation.

Comparing home battery system options
The table below can help to compare different system designs and product abilities – to make sure you’re getting the functionality you need out of your system.
Grid Defection
True independence from the power grid. 'Cut the cord' and live with complete control over your power supply and costs.
Autonomy Systems
Designed to power your whole home, for grid independence whilst still keeping the grid connected.
Grid Support / Augmentation
Use solar panels and batteries to support an existing grid connection when the grid alone can't provide enough power.
Batteries with solar: how do they work?
Solar Battery Storage
An on-grid battery system stores excess solar energy generated during the day so it can be used later when solar production is low or electricity demand increases. Solar panels produce electricity that powers your home first, while any unused energy charges the battery system. Once the batteries are full, extra power can be exported back to the grid.
During the evening, cloudy weather, or peak usage periods, the battery supplies stored energy to your home automatically. If additional power is needed, the system seamlessly draws electricity from the grid. Some advanced battery systems can also provide backup power to selected appliances during grid outages, helping improve energy independence and reliability.

Grid Support solar & battery system
Grid Support, or Augmentation, Systems are designed for properties where the existing grid supply simply can't provide enough power for the way the home or business needs to operate. A solar and battery system works alongside the grid to supply the additional power required, effectively filling the shortfall during periods of higher demand. This can help support larger appliances, machinery, workshops, electric heating, EV charging and other high-load equipment without relying solely on the available grid capacity. In some cases, the system can also increase the usable phase capacity of the property, allowing a single-phase supply to support three-phase loads. It's an ideal solution where upgrading the grid connection is difficult, expensive or impractical.

Grid Defection solar & battery system
Grid Defection is the ultimate step in taking control of your energy supply and eliminating ongoing dependence on electricity retailers and network charges. Unlike a grid-connected battery system, Grid Defection involves permanently disconnecting the property from the electricity network and abolishing the existing meter. This process does involve additional costs, paperwork and coordination, with requirements varying between electricity retailers and network utilities. We'll help guide you through the process and provide the information needed along the way. Once the meter is removed and your off-grid power system is commissioned, your home becomes genuinely energy independent, giving you complete control over how your power is generated, stored and used, without an electricity bill arriving each quarter.

Full Control of Your Power
On-Grid autonomy solar & battery storage system
Your solar inverter converts DC power from your solar panels into usable AC electricity for your home during the day. Surplus energy charges your batteries and may be exported to the grid if permitted. The batteries supply power when solar output is low or at night, with the grid covering any remaining demand. During a blackout, the system can continue operating using stored battery energy and solar power if available.

Energy storage options for your needs
Depending on your goals, there will be an ideal battery storage solution for you.
If an Autonomy battery system is not quite enough for you and you’d rather have total grid independence, then there’s nothing stopping you. Chat to us about the ideal Grid Defection System option for you. We will ensure you have the right technology, design, and capacities without compromising your lifestyle and power supply with or without grid support.
Grid Defection and true Off-Grid Systems have important differences to Autonomy Battery Systems. Check out our Off-Grid Systems page, or get in touch to discuss your options.
How much battery storage you need will depend on a few things:
How much grid consumption would you like to offset?
Do you have enough surplus solar generation, or is additional solar required?
Do you want blackout protection functionality, and at what level?
Would you like the ability to expand, allowing you to eventually go off-grid?
Here are some further considerations:
How much energy you consume at night (especially in winter) tells you how much storage you will need
You will also need enough ‘spare’ solar to fully recharge that amount of storage
If you already have solar, then how much you’ve been exporting to the grid during winter probably tells you how much battery capacity to buy (any more and you won’t have enough solar to recharge it for part of the year anyway)
