Off Grid System - Large Residential 37.9kWh Tubular Gel

Whether you live in a rural location without reliable grid access, or simply want a more sustainable lifestyle, our off grid systems provide the perfect power solution. Ideal for small dwellings such as shacks, cottages, and holiday retreats, this off grid system is designed for applications with a daily power usage of 8-16kWh.

Built as a relocatable all-in-one unit, our off grid systems are self contained in a durable steel cabinet. This complete cabinet solution houses all core components, with a slimline design ideal for situating against the wall of a garage.

At the heart of each off grid system is the Integrated Power System (IPS). Combining the functionality of a solar charge controller, pure sine wave inverter, and multi-stage AC battery charger into one central unit, the IPS provides a central system for monitoring and controlling all aspects of the system. The IPS is prewired into a system board containing breakers, fusing, cabling, and everything else that is required - all meeting current Australian standards.

kW Hour Meter

The kW hour meter measures the power that comes out of the system to enable you to keep track of how much power the system is producing. This is helpful in understanding the effectiveness of the installation, and is very beneficial in discovering issues and problems.

Generator Input Plug

The generator input brings 240V from any external lead into a plug like you see in caravans. You can attach any external generator (petrol, diesel, or even coal fired) to charge the batteries and supply power to the leads.

Change-over Switch

In the event of emergency system failure, the change-over switch allows you to bypass the IPS and provide power directly via generator or grid connection.
