⚡ A glimpse into the history of power in the Snowy Monaro ⚡
Before smart meters, solar systems and modern switchboards, bringing electricity to a property looked very different.
This old Delco-Light battery instruction sheet is a reminder of a time when many rural homes, farms and sheds created and stored their own power.
A Delco Light battery refers to the heavy-duty glass-jar lead-acid cells used in historic Delco-Light power systems from the early to mid-20th century. These antique, 2-volt glass cells were wired in series to provide the 32-volt direct current (DC). These early systems used a small engine-driven generator to produce electricity. The power was then stored in large lead-acid batteries, similar in concept to today’s energy storage systems. The batteries supplied power when needed — allowing lights, appliances and equipment to operate even when the generator wasn’t running.
Maintaining these systems was a hands-on job. Battery levels had to be checked, water added, charging cycles managed and connections kept clean to ensure reliable operation. The instructions even show the importance of regular “equalising charges” to keep the battery banks healthy.
While the technology has changed dramatically, the principle remains the same — generate, store and use energy when it’s needed.
The Snowy Monaro has always been a region of innovation and self-reliance, from early off-grid power solutions through to the engineering legacy of the Snowy Mountains Scheme.
At Reactive Energy, we’re proud to be part of a region where electrical technology has powered homes, businesses and communities for generations.
From heritage systems of the past to the energy solutions of tomorrow — we keep the power flowing. ⚡
