Off-Grid
Solar Systems
An off-grid solar system is a stand-alone power system. The self-contained unit generates and stores electricity from the sun. These systems feature a number of highly effective photovoltaic solar panels and some batteries. The solar panels collect energy from the sun and the batteries store the energy.
During a period of high demand or low power production (e.g. night), the appliances draw energy from batteries instead. An inverter converts the energy stored into usable electricity.
Unlike traditional grid-tied solar systems, off-grid solar systems are not connected to the power grid. They produce clean, green, free power.
Keep your lights on.
Power outages are becoming increasingly common due to factors such as rolling blackouts, lightning storms, and increased time spent at home. With our help, you can ensure your home is the one on the block with the lights shining bright.
Get more energy independence.
Electricity costs are on the rise and utilities often charge more during peak times. But there’s a better way. By generating clean energy and storing excess power for peak times and outages, you can break free from power company grid games and enjoy energy independence.
Control your own home.

What is an off-grid solar system?
-
- Solar panels: collect energy from the sun and convert it into DC electricity
- Battery bank: stores the DC electricity generated by solar panels
- Charge controller: regulates the energy that goes into the battery banks to prevent overcharging
- Inverter: Converts DC electricity from the battery bank into AC electricity that is used to power a home
- Generator: provides power when the battery bank runs low or when there isn’t enough sunlight to generate energy
How does an off-grid system work?
Are you tired of relying on an electricity company for your energy needs? It may be time to break free with an off-grid solar system.
Anything that can be powered by grid energy can be powered by solar energy. These innovative systems operate by generating electricity through solar panels. Once installed, they instantly start generating electricity from panels on the roof, storing it in solar batteries. This power can then be used to provide energy to any appliances; lighting, fridges, televisions and more.
You can say goodbye to power bills forever. Off-grid solar power systems are designed to meet all your energy needs without relying on a power company.
