Over the last few months we’ve had lots of callouts to replace the main isolator switch after storm water has got in and shorted it out. Industry standards have changed over the last 10 years and so we replace them with ones that meet current waterproofing specifications. This is a nationally recognised problem and households with older systems should get their isolators inspected immediately. Our accredited technicians frequently inspect systems which have dangerous faults due to poor-quality workmanship and we also see issues related to storm-damaged or inferior-quality panels and faults in inverters, which are the heart of a solar system. Birds and rodents can damage your system, especially components like wiring, connectors and cable insulation.
