BATTERY BACKUP
Battery storage and blackout backup are different features. We help you choose a system and a backup arrangement that match the way your home needs to run.
KNOW WHAT YOU’RE BUYING
A conventional grid-connected solar system stops supplying the home when the grid goes down. Backup operation requires equipment and a design that can safely separate the backed-up circuits from the grid.
A battery advertised for energy storage does not automatically include blackout backup. The quote needs to identify the backup hardware, supported circuits and operating limits of the proposed configuration.
Read the Australian Government’s solar design guidance for more on backup and system design.
DESIGN AROUND YOUR PRIORITIES
Start with practical needs such as selected lighting, refrigeration, internet and a few power points. The circuits included must be specified in the design.
Air conditioning, cooking and pumps can place substantial demands on a backup system. Starting loads and simultaneous use need assessment.
A whole-home connection does not mean unlimited power. Available output, energy reserves and phase support still determine what can run.
POWER, ENERGY & CONTROL
Power is the rate at which the system can supply electricity. Continuous and surge output affect the appliances it can operate together.
Energy capacity affects runtime. Actual runtime changes with appliance demand, available charge, reserve settings and operating conditions.
A reserve setting can retain charge for an outage. Holding more energy in reserve changes how much is available for everyday use.
Solar can recharge some backup systems during an outage when the selected equipment supports that mode. Confirm this explicitly, especially with an existing inverter.
An inverter or battery on one phase may only back up the circuits connected to that phase. We check the supply, essential circuits and proposed equipment before describing a system as suitable for your home.
We assess the existing inverter, battery compatibility, switchboard and cable routes. Retrofitting may require additional equipment or a different configuration.
YOUR QUESTIONS, ANSWERED
No. Backup capability depends on the battery, inverter, isolation hardware and installation design. Ask for the supported circuits and backup specifications in writing.
Runtime depends on usable stored energy, appliance demand, the charge available at the start of the outage and any supported solar recharge. We can discuss scenarios using your chosen essential loads.
Only within the configured system’s power and energy limits. High-demand appliances and starting loads may require a larger system or limits on simultaneous use.
Transfer behaviour depends on the equipment. Do not assume it is suitable as an uninterrupted power supply for sensitive or critical equipment; check the manufacturer’s specification.
We service the Central Coast, Sydney, Newcastle and Maitland/Hunter. Tell us which appliances matter during an outage and whether the property already has solar or a battery so we can discuss the assessment.
Our team assesses solar battery backup requirements across the Central Coast, Sydney, Newcastle and Maitland/Hunter. We begin with the circuits you want to support, your electrical supply and any existing solar equipment. A backup quote should explain supported loads, isolation equipment and the system’s operating limits.
