Making Solar Safer

How to make solar safer

Safer Solar technologies reduce the risk of electrical arc faults, which in turn reduce the risk of solar-related fires and electrocution. The two main Safer Solar technologies available in Australia are Power Optimisers and Microinverters.

Both Microinverters and Power Optimisers control power generated by the solar panel AT the solar panel and constantly monitor electrical performance for faults that may cause a fire.

I want safer solar. What questions should I ask?

Technology

What does it mean?

Rapid shutdown

A quick and easy method to de-energise solar panels to ensure complete safety for you and first responders in the event of an emergency.

DC arc-fault prevention

Technology that systemically prevents arc faults from ever occurring.

Arc fault detection

The ability for the solar system to detect and proactively shut down if an arc-causing event occurs.

Panel-level visibility & performance

This allows you to monitor individual panel performance and health.

All-AC or safe DC output

Arc faults can only be sustained by high-voltage current of more than 120 volts. Cheap solar systems sold in Australia operate at 600-1000 volts. Safer Solar systems are either all-AC or have controlled DC voltages.

Keeps tradespeople & first responders safe

Controlled voltage solar with rapid shutdown ensures tradespeople and first responders are less exposed to dangerous electrical currents.

Safer Solar technologies that reduce the risk of electrical fires and injury are available in Australia today,
but current regulations do not promote their use.

SAFER SOLAR FACT

A recent study by a reputable electrical contracting business that specialises in solar service and repairs found that of the 5811 service visits undertaken by their business in the last 12 months, 671 failed DC isolators were replaced. This is a greater than 11% failure rate per annum, concerningly these failures showed evidence of DC isolator fires or were at the early stages of becoming a fire hazard.
