Off-Grid System

Off-grid power systems supply electricity to properties that are not connected to the public electricity network. These systems are often referred to as “stand-alone power systems” (SAPS), or “remote area power systems” (RAPS).

These systems are independent power stations capable of powering a wide range of applications with dependable and reliable electricity that is no different to that supplied by the national electricity grid. Whether it be for a small or large new or existing home, a station, business or an entire community that depends on large diesel generators, off-grid stand-alone power systems are commonly the reliable, clean, hassle free, cost competitive answer!

How do Off-Grid Systems Work?

Off-grid systems supply electricity to properties that are not connected to, or have chosen to disconnect from, the public electricity network.

Photovoltaic (PV) solar panels convert sunlight to direct current (DC) electricity, which is then fed through the solar inverter to create usable alternating current (AC) electricity. AC electricity is then sent to the switchboard, where it is sent to the household appliances that are using electricity at the time, and any surplus electricity is sent to the battery bank to recharge it.

The inverter/charger will stop the solar system from recharging the batteries once they are full. When your solar system is not producing electricity, your battery bank will send power to your household appliances.

If the battery bank state-of-charge level gets too low, the inverter/charger will turn on the fuel generator automatically to power the house electrical appliances and recharge the battery bank.

There are two different ways of configuring an off grid system – AC-Coupling and DC-Coupling – and each have unique advantages. The configuration type will have an impact on the life expectancy, efficiency and flexibility of your system.

Complete System
The Complete System is the most versatile of our standalone power product range, capable of powering a broad range of medium to large properties including homes, farms, stations and small businesses, with all the reliability of mains power.

Adjusted to meet your requirements, the Complete System is our most popular product and is suitable for properties with standard single-phase appliances.
