Buy a Safe Solar System
When talking to a potential supplier of a solar system for your home or business ask them about safe solar technologies, and more specifically, request a quote for a microinverter or DC optimiser based system that eliminates DC arc faults. If the supplier can’t do this or attempts to dissuade you from purchasing these systems, for any reason, the best advice would be to contact another supplier.
All reputable solar businesses in Australia either offer safe solar technologies as their first option, or would be happy to supply a quote for one on request.
A business that doesn’t offer this option or tries to talk a customer out of using safe solar technologies should be avoided.
