Stage pic2Leading the country as Australia’s first officially credited Carbon Neutral School, South Fremantle Senior High School is also believed to have built Western Australia’s first Mobile Solar Stage.

The towable dual axle Mobile Stage provides a sheltered, easily set up platform for the Schools’ Specialist Music Students who can now perform and tour to almost limitless localities and audiences, self sufficiently.

The Solar Stage is more than a sustainable performance venue with musicians and sound technicians; it’s also a teaching tool for things like event planning, road tripping and participation in a variety of causes in different communities.  It’s a truly fantastic idea.

The Solar Stage is required to power speakers, microphones, lights and electrical instruments for two days or one day and half the night, so Install A Gadget set about designing an adequate Solar System, incorporating the only batteries up for the job – Lithium.

After days of prior preparation, programming and testing,

Install A Gadget installed the following over 4 days....


LiFePO4 batteries are a perfect fit for the Sth Fremantle SHS Solar Stage. 
They are smaller and up to four times lighter than AGM (Absorbed Glass Mat Deep Cycling) batteries which is critical to keeping a safe towing weight.
The weight saving is quite significant. The 2x 400Ah LiFePO4 batteries in The Solar Stage weigh 110kgs. To achieve the same amount of useable energy from AGM batteries, the AGM’s would weigh a total of 420kgs!  That’s over a quarter of a tonne of weight saved!

LiFePO4 Batteries also have 80% usable energy compared to AGM’s which only has 50%, they cycle (charge and discharge) approximately four times more than that of an AGM battery and Lithium batteries hold their charge very high and stable, meaning the equipment powered by the system will work more efficiently. 
LiFePO4 batteries can also accept a charge from the Solar System up to four times faster than AGM’s so students’ll be playing sweet music all day long.

20171109_162059One of the standout features of the Easy Solar is its pairing with software which allows Install A Gadget to remotely monitor and manage the system, so long as there is mobile phone reception. 

The Wi-Fi feature will also allow Live Streaming from the Colour Monitor to a tablet connected to a big screen.  So not only will audiences be enthralled by talented young entertainers, they’ll be fascinated to see exactly where energy from the stages’ system is coming in and going out, as it happens.

20171109_162445If the reason those alarms are sounding is not attended to, The Lithium Control Units step in to protect the batteries.  If the SOC is getting low, the protection system switches off the Inverter and swaps to Charger only and will shut the whole system down to protect the batteries if the SOC gets too low.

The Lithium Protection System will also switch the Charger and Solar Controller off if the battery’s voltage gets too high.  It shouldn’t happen anyway but it’s insurance to protect the batteries.

Congratulations to Sth Fremantle SHS for another successful venture in sustainability

and for facilitating valuable opportunities to its very lucky students.

It has been a pleasure to partner with you on such a special project.

Install A Gadget will be eagerly following the Students’ Solar Stage performances so watch this space.  We can’t wait to see how far and wide they travel and what they get up to.

We wish Students & Staff many wonderful experiences and every success in their musical careers.
