Large Off-Grid Solar Power System Case Studies
Off-Grid Power System Load Profile
To accurately design your ideal off-grid solar system and provide you with a quote, we need to understand your property’s power usage.
We do this by asking you to complete an Energy Load Profile in which you list all the appliances and utilities that use power with an estimate of their usage amount. Once this is completed, we can recommend the best system design and size for you.

The Off-Grid Energy Advantage
Experience
Installing battery storage isn’t as simple as installing plain solar. Our head technician has been designing off-grid systems since 2002, and our core team has been working with battery systems since 2006.
Quality Components
It’s unwise to make compromises when you are energy independent. There is a world of difference in the quality of system components, so we make sure we only source the very best.
Expert Design
Inferior off-grid systems provide frustratingly unreliable power and a costly short system life due to poor sizing, mismatched equipment, non-compliant design, and unsafe installation. Our expert technicians ensure these pitfalls are avoided.
Happy Customers
We have hundreds of happy battery storage customers across Australia. When you ask us for a customer reference, we can provide someone with an off-grid system just like yours.
Integrity
We understand the responsibility of providing reliable power, and being available 24/7 to troubleshoot. We value honesty and integrity in our staff, and always strive to exceed expectations.
Endorsed, Certified & Awarded
Our fantastic, hard working team has proudly received numerous awards, industry endorsements, and certifications from respected organisations.
