Our high-quality system includes everything you need to generate and store your own clean and renewable energy, from the solar panels and batteries to the charge controller and inverter. With enough power to meet the needs of a small to medium-sized household or business, our 3kW system provides a reliable and sustainable alternative to traditional grid electricity.


Energy independence:

With an off-grid system, you are not dependent on the grid for your electricity needs. This can be particularly beneficial in remote locations where access to the grid may be limited or unreliable.


Reduced electricity bills:

By generating your own electricity, you can reduce or eliminate your reliance on the grid, which can lead to significant savings on your electricity bills over time.


Environmental benefits:

Generating your own electricity from solar power is a clean, renewable and sustainable way to meet your energy needs, which can help reduce your carbon footprint and contribute to a healthier environment.



Off-grid solar systems are flexible and can be designed to meet the specific energy needs of your household or business. 

Increased property value: Installing a solar system can increase the value of your property, making it a smart investment in both the short and long term.
