The head of the certified electricians’ association, George Kyriakou, on Wednesday warned the public about faulty cut-off switches linked to photovoltaic (PV) installations, and separately cautioned against rushed installations of smart meters.

Speaking on CyBC’s morning programme, Kyriakou emphasised the importance of regular inspection and maintenance of PV systems. While incidents involving faulty disconnectors are relatively rare, he said, eight models have already been recalled.

“If you see smoke or fire emanating from the DC system of the installation, this can’t be instantly turned off as with a conventional supply system, because the sun keeps shining, generating a live current,” Kyriakou warned.

“It’s extremely dangerous, and no one should ever attempt to disconnect the switch with their bare hands.”

Kyriakou explained that a faulty disconnector may be located either next to the inverter or under the solar panels on the roof. He advised anyone who suspects a fault to immediately send a photo to the original installer. He added that some switches do not meet compliance standards and should be checked pre-emptively.

He estimated that faulty switches have been on the market for about five years.

“So far, I have received about 150 photos, and more than half of the components shown were unsuitable,” Kyriakou said, adding that 15 to 20 of them had caught fire.

From the department of electromechanical services, electrical engineer Michalis Nicolaou said that targeted sampling of disconnectors is ongoing. He reassured consumers that they are entitled to a free replacement within two years of installation.
Nicolaou said that professionals, importers and the public are being regularly updated, and the likelihood of serious danger from disconnectors remains very low.

Kyriakou also issued a stern warning about the Electricity Authority of Cyprus’ (EAC) planned installation of 500,000 smart meters.

“We will have many accidents,” he warned.

He advised that smart meter installations be done in the presence of the property owner, who should confirm that the correct current has been restored. This would help prevent damage to household appliances.

Kyriakou cited an incident in Nicosia where a smart meter installation caused over €5,000 worth of damage due to burnt-out appliances.
He also criticised the current €6.50 compensation per meter as insufficient, saying it encourages electricians to rush through installations that should take about an hour. He stressed the need for prior notification to homeowners or residents to ensure safety.

Installations in weekend or summer homes are especially problematic, he said, because appliances may only restart after the technician has left, making damage harder to detect and compensation harder to claim.
