For many homeowners, a 42kWh solar battery is an important step towards greater energy independence. Instead of relying heavily on the grid, you can store more of the solar energy your system generates and use it when you need it most.
A larger battery can help you:
Reduce your everyday reliance on grid electricity.
Maintain a larger energy reserve during cloudy weather or lower solar generation.
Enjoy greater control over your home's energy supply throughout the year.
While a 42kWh battery can support near off-grid living, a fully off-grid system requires careful solar design, additional equipment, and site-specific planning. Our team can help you determine the most suitable solution for your property.
A 42kWh battery installation is a specialist project, and Zip Solar manages every stage from system design to final commissioning.
A premium 42kWh battery system built using modular battery units and backed by the manufacturer's warranty.
Installation by experienced SAA-certified professionals trained in large-capacity battery systems.
Advanced monitoring that lets you track solar generation, battery storage, and backup status from your smartphone.
Assistance with eligible government battery incentive documentation.
Ongoing support and servicing to keep your system performing at its best.
As part of the installation process, we also complete a detailed electrical and switchboard assessment to ensure your property is ready for a larger battery system.
A 42kWh solar battery performs best when paired with a solar system capable of generating enough energy to charge a larger storage system efficiently.
A 13kW solar system is a strong option for residential properties looking to maximise daily solar generation and make effective use of a 42kWh battery.
Explore our 13kW Solar SystemsFor larger properties or residential-commercial crossover applications, a 20kW solar system can provide the additional generation needed to support high-capacity battery storage.

One of the biggest advantages of a 42kWh solar battery is the additional backup capacity it can provide during unexpected power outages.
A larger battery can help:
Keep essential household circuits operating during a blackout.
Provide a greater energy reserve during extended periods of poor weather.
Improve resilience for properties located in bushfire, storm, or outage-prone areas.
The actual backup duration depends on your property's energy usage, the appliances being powered, and your overall system design. We'll recommend a solution based on your backup priorities.

Eligible 42kWh solar battery systems can receive support through the Australian Government's Cheaper Home Batteries Program. Support is applied across multiple battery capacity tiers, allowing the entire eligible battery capacity to receive assistance under the program.
The program operates under a nationally regulated framework administered by the Clean Energy Regulator. Our team will explain how the current incentive applies to your installation and assist with all required documentation.
Because of their larger capacity, 42kWh battery systems require more detailed planning than smaller residential batteries.
Before installation, Zip Solar will:
Complete a thorough site and electrical assessment.
Check whether switchboard or electrical upgrades are required.
Assess three-phase power requirements where applicable.
Guide you through any grid or council approval processes if needed.
Our team manages the entire installation process, ensuring your battery system is designed specifically for your property and energy goals.

It can support greater energy independence, but a fully off-grid system depends on factors such as solar generation, backup requirements, and site design. We'll assess your property and recommend the most suitable solution.
Some properties may require switchboard upgrades, additional protection equipment, or three-phase electrical work. We'll identify any requirements during your site assessment.
Backup duration depends on which appliances are running and how much electricity your household uses. We'll help design a system that aligns with your backup expectations.
Yes. It's often chosen for rural and acreage homes where energy independence and reliable backup are key priorities.
Yes. Eligible systems can receive support under the program, and our team will guide you through the application process.
