Power your off-grid setup with confidence using this 1.2kW solar panel bundle, designed for caravans, camper trailers, RVs, 4WDs, tiny homes, and remote off-grid systems across Australia.
Each 300W monocrystalline panel delivers exceptional efficiency, reliability, and long service life—built to perform in Australia’s demanding climate.


☀️ High-Efficiency Monocrystalline Design

These A-grade 300W 12V solar panels use high-efficiency monocrystalline cells for superior power generation and low-light performance.
The rugged fixed-mount design provides stable, consistent output across a wide range of conditions—ideal for charging 12V, 24V, or 48V battery systems via MPPT controllers.


⚙️ Built Tough for Australian Conditions

Each panel features a corrosion-resistant anodised aluminium frame and tempered glass surface engineered to withstand heat, wind, dust, and rain.
Perfect for both mobile and fixed installations, from caravan rooftops to off-grid cabins and marine applications.


🔋 Flexible System Integration

With a total rated output of 1,200W, this 4-panel bundle can be wired in series, parallel, or series-parallel, offering full flexibility to match your inverter and charge controller setup.
Suitable for all major 12V, 24V, and 48V off-grid systems.

⚡ Bundle Output & Performance

  • Total Output: 1,200W (4 × 300W panels)

  • Estimated Daily Energy (5 sun hours): ~6kWh/day before system losses

  • Enough to power fridges, pumps, lights, tools, and inverters for full off-grid independence.


🔌 Installation Recommendations

  • Mount panels facing north (in Australia) with tilt angle matching your latitude for optimal solar gain.

  • For 12V battery systems, wire panels in parallel; for higher-voltage systems, use series or series-parallel configuration.

  • Use a quality MPPT charge controller rated for ≥70A.

  • Recommended cable size: 25–35mm² for long cable runs.

  • Allow airflow beneath panels for cooling and performance.

  • Avoid shading from vents, antennas, or awnings—partial shading can reduce output.
