The EarthGuard EG-600 is a standalone device
for integration with approved third-party controllers,
power conversion equipment and battery systems.
Utilizing proprietary detection techniques, the AERL
EarthGuard Insulation Monitoring Device simultaneously
monitors up to two circuits (20 - 600Vdc) for conductor
insulation degradation.
The EarthGuard EG-600 monitoring device satisfies
the earth fault detection requirements of both
AS/NZS 5033:2014 & AS/NZS 5139:2019 with onboard
audio/visual alarms, and alarm relay outputs for
external fault indication
AERL
Australian Energy Research Laboratories (AERL) was originally founded by Stuart Watkinson (BE Elec. Eng., Grad. M.I.E.A) in 1985, after the development of the “Power Optimiser”, a revolutionary solution to a complex problem.
Unlike many inventors, Stuart possessed not only a great idea, but also the entrepreneurial skill to turn it in to a commercially viable product. The “Power Optimiser” would eventually come to be known as the AERL MAXIMISER™, the world’s first truly Universal Maximum Power Point Tracker (MPPT).
After the completion of his thesis, titled “The Generation of Electricity from Solar Energy”, Stuart devised an electronic unit that would efficiently extract the maximum electrical power from a small photo-voltaic array, and deliver it to a DC electric motor to assist in propelling a 4-rider solar tandem pushbike.
The pushbike, “Solar Tandem”, was a unique vehicle designed to combine human effort – in the form of pedal power – with electrical energy from solar cells to create an energy-efficient method to transport 4 riders at unusually high speeds. The experiment intended to prove that a hybrid system of human and photovoltaic [PV] energy can eliminate the need for conventional batteries, while minimising the size of the PV array required for a given application.
