Shop off-grid solar kits for caravans, 4WD touring, sheds, cabins and independent power systems across Australia. Compare compact 12V packages and larger solar, battery and inverter combinations, then check each listing for the exact components, ratings and installation requirements.
Off-Grid Solar Kits for Australian Homes, Cabins, Sheds & Travel
An off-grid solar kit combines selected components needed to generate, regulate, store or use solar energy away from a standard mains supply. The right system depends on what you need to power, how many hours or days of autonomy you want, the available roof or ground space, and the solar conditions at the installation site.
This collection is StarPower’s primary range for complete and near-complete off-grid systems. It spans portable and 12V applications through to larger packages suited to sheds, cabins and other independent-power projects. Inclusions differ between products: some packages include panels, battery storage, a charge controller or inverter, while others are designed as a foundation for a tailored system. Always review the individual product page before ordering.
Choose an Off-Grid Kit by Application
Caravan, Camper Trailer & 4WD
Touring systems commonly power a fridge, lights, water pump, communications equipment and device charging. Start with your daily watt-hour use, then match the solar input, battery capacity and controller to the number of days you expect to camp without driving or mains charging. Browse flexible solar panels for weight-conscious roof applications or solar blankets for portable charging at camp.
Sheds, Cabins & Remote Properties
Larger off-grid systems may need to support pumps, refrigeration, tools, electronics and selected household loads. Starting currents, seasonal solar variation and consecutive low-sun days can materially change the required inverter, battery and array size. For these projects, use the kit as a system-design starting point and obtain qualified advice before installation.

What to Check Before Buying
-
Daily energy use: add the wattage and expected runtime of every appliance to estimate daily watt-hours.
-
Solar array size: allow for local sunlight, panel orientation, temperature, shading and real-world system losses.
-
Battery storage: choose usable capacity around overnight demand and the number of low-sun days you need to cover.
-
Controller limits: confirm maximum PV open-circuit voltage, charging current, battery voltage and battery-chemistry settings.
-
Inverter rating: check continuous output, surge capacity, system voltage and compatibility with every intended 240V load.
-
Kit inclusions: verify panels, mounting hardware, batteries, cables, fuses, isolators, controller and inverter rather than assuming every item is supplied.
-
Installation: cable size, over-current protection, earthing, ventilation and equipment location must suit the system and manufacturer instructions.
Match the Core Components
A reliable off-grid system is designed as a whole. Compare fixed solar panels for permanent arrays, lithium LiFePO4 batteries or AGM deep-cycle batteries for storage, MPPT solar charge controllers for compatible solar charging, and power inverters where 240V AC output is required.
Do not select a kit by headline wattage alone. Panel watts describe generation capacity under standard test conditions; battery watt-hours describe stored energy; and inverter watts describe the AC load the inverter can supply within its stated limits. These figures work together but are not interchangeable.
Installation, Compliance & Safety
Off-grid systems can involve high DC currents, hazardous battery energy and 240V AC wiring. Fixed electrical work and larger systems should be designed and installed by appropriately qualified professionals in accordance with applicable Australian requirements and the equipment manufacturer’s instructions. Grid-connected operation is a separate application and must not be assumed from an off-grid product listing.
Off-Grid Solar Kit FAQs
What size off-grid solar kit do I need?
Begin with a load list and daily watt-hour estimate. Then account for local solar conditions, charging losses, battery autonomy and appliance surge demand. A caravan fridge-and-lighting setup has very different requirements from a cabin with pumps and 240V appliances.
Does every kit include a battery and inverter?
No. Inclusions vary. Some kits are complete combinations, while others include only selected system components. Check the product title, specifications and “what’s included” information on the individual listing.
Can I use lithium or AGM batteries?
Many systems can be configured for a compatible lithium or AGM battery, but the controller, charger and inverter settings must suit the chosen chemistry and voltage. Confirm compatibility before connection.
Can I expand the system later?
Expansion may be possible only within the voltage, current and capacity limits of the controller, inverter, battery bank, cabling and protection devices. Plan future growth during the initial design rather than assuming extra panels or batteries can always be added.
