Off Grid: Discover the future of energy
If you've just bought a new plot of land that's not currently connected to the grid or working on a remote development project and considering Off Grid as a way to generate your power, you've arrived at the right place. Rainbow Power have been in the solar industry in Australia since 1987 (one of the first ever registered solar businesses!) and we couldn't be more dedicated to sustainability, reliability and client satisfaction.

How do your pre-built systems work?
- Our manufacturing team pre-wire and configure selected Off Grid Systems in our warehouse to streamline the installation process. They can be shipped anywhere in Australia for a Licensed Electrician to install. Each kit includes the following components:
-
Solar Panels: High-efficiency solar panels to convert energy from the sun!
-
Custom Solar Array Framing Kit: Tailored to fit your specific roof type, ensuring secure and optimal placement of the solar panels. NOTE: that standard racking is supplied for the portrait layout. Please contact us for landscape pricing.
-
Solar Cabling and Accessories: Includes all necessary wiring and accessories to connect the solar panels to the inverter.
-
Distribution Board: Fully equipped with AC circuit breakers and bus bars for 240V connection of inverters, generators, and site loads. Built to comply with all Australian standards.
-
Batteries and Weatherproof Battery Box: Durable batteries housed in a protective box to ensure longevity and performance.
What happens with Frieght & Logistics for your pre-built systems?
To ensure safe and efficient delivery throughout Australia, our systems are typically dispatched in 3-4 pallets. Below are the dimensions for an example system with 18 solar panels and 4 battery modules:
-
Pallet 1: Contains solar panels and the distribution board, this pallet measures 1.8 x 1.2 x 1.5m and weighs 500kg.
-
Pallet 2: Contains batteries and inverters, typically measuring 1200 x 1200 x 1500mm and weighing 400kg.
-
Pallet 3: Contains the rails for the solar frame, which are at least 3.6m long and weigh approximately 30kg.
Freight costs are dependent on where you live in Australia and we will provide a freight quote once your system design is finalised. Our dispatch team will inform you of your final delivery dimensions and weights once we complete the packing of your equipment. Our freight partner will deliver to your closest depot for collection. Please consider these sizes when arranging the collection of equipment from the depot.

What do IP ratings mean for Off Grid systems in Australia?
IP (Ingress Protection) ratings are two-digit numbers associated with an electrical or mechanical enclosure, which indicate the item's resistance to various types of unwanted intrusion - from weather and insects to snakes! The higher the rating, the higher the resistance.
The systems we sell range from IP 21 to IP 65. What type of box or mounting we recommend depends on the setting for your system. Where will it be housed? In a shed? Under shelter etc.
The reality is that Solar Inverters are lovely and warm in winter and its common to get snakes moving into an IP 21 rated system during winter. In summer, wasps and ants like to find their way into the inner workings of Off Grid solar systems. This can result in the need to replace inverters or in some cases, entire systems.
For lower IP ratings that require housing, the type of housing is deeply considered by our team. Solar Inverters generate a lot of heat (especially on hot summer days when you're running your aircon) and usually require a temperature below 40 degrees to function optimally. A lot of our competitors house systems in cheap fan-cooled boxes. At Rainbow Power, we don't believe a robust power system for the future should rely on a 15c low-cost fan as its point of failure. Instead, we build systems that can take on the conditions we put them into, whether that's in Koziosco or the Whitsundays. You want your system to be set and forget for decades not just on fair weather days.
What sort of timframe can I expect for my Off Grid System?
The timeframe for each Off Grid System will depend on the type of system you choose and if we're installing it. If you're within a 2 hour radius of Nimbin, we're happy to install your Off Grid System. If you're located outside of this area, we'll ship your system to you for installation by a licenced electrician. If your system requirements require a bespoke design, this will generally take at least 4 weeks (from payment) to build and then one week to ship (depending on your location).
Once your system is designed, your Off Grid Designer will work with you on timeframes. Some Off Grid porjects are designed and scoped prior to the development even starting but rest assured we take all this into consideration when we're building the plan.
What if I wanted something custom made or my project is different?
We'd love to hear from you! Building custom made Off Grid solar systems really is our jam. It gives us a genuine kick to design, build and install Off Grid systems that allows our customers to Power On - sustainably.
