Off Grid System – Medium House 21.6kWh AGM

You Are Here: Home / Shop / Off Grid Solar Power Systems for Stand Alone Solar Power / Off Grid System – Medium House 21.6kWh AGM

AGM Battery Storage

With up to a 12 year designed service life and over 2200 cycles at 30% DOD, AGM batteries are an ideal mix of performance and value. Perfect for providing reliable medium-long term power storage, AGMs won’t let you down.

Pre-wired, tested, and ready to go

Our off grid systems are pre-wired in our factory, with full testing done on key components to ensure everything is functional and ready to go. Installation on-site is simple – just connect the battery bank and solar.

Auto-Start Generator Functionality

Simply connect a compatible generator and set up when you want it to engage. If the batteries are getting too low or inverter is being overloaded, our system will automatically switch the generator on/off as required.

3 Days Autonomy

Don’t worry about extended bad weather conditions or emergencies leaving you without power generation. Our system will run for up to three days without power input, giving you peace of mind to weather the storm.

Modular and expandable

Start with what you need now, while having the confidence that adding extra components down the track will be intuitive and easy. Our off grid systems ensure you are ready for the future if your needs change.

Clean Energy Council Approved

Our off grid systems are built with components certified by the Clean Energy Council, allowing you to claim back solar credits for the installation of your system. Most systems receive thousands of dollars back!

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 4-8kWh.

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.

System Inclusions

21.6kWh AGM Battery Bank

8x 450AH 6V AGM Deep Cycle Batteries. 2200 cycles at 30% DOD, 7-10 year average lifespan, 12 year chemistry life.

The Sunny Island

The ideal solution, especially for demanding PV arrays and partially shaded systems. Enjoy proven technology combined with intelligent ideas.

Battery Cabinet with Venting

Durable steel cabinet with vermin mesh covered ventilation. Lockable lower doors, forklift skids for transport or relocation.

Prewired System Board

Internal electrical board prewired with IPS, cabling, breakers, fusing, and all other electrical components.

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.


A basic off grid system for medium-sized applications with medium service lives.
