The INVERTER Warning Dual Supply Isolate AC And DC Before Carrying Out Work Sign is designed to clearly warn electricians, maintenance engineers, contractors and authorised personnel that photovoltaic inverters are connected to both AC and DC electrical supplies. Featuring a bold warning message, this sign reminds anyone working on the system that both electrical supplies must be safely isolated before carrying out inspection, maintenance, servicing or repair work.

Ideal for installation adjacent to photovoltaic inverters, inverter cabinets, plant rooms, electrical enclosures, battery storage systems and renewable energy installations, this sign is suitable for domestic, commercial, industrial, agricultural and public sector solar PV systems. It provides a highly visible safety reminder wherever inverter maintenance or electrical isolation may be required.

Unlike many conventional electrical systems, photovoltaic inverters operate with two independent power sources. Even after the AC mains supply has been isolated, hazardous DC voltages generated by the solar panels may still be present while daylight is available. Failure to isolate both supplies can expose personnel to the risk of electric shock, arc flash and serious injury. Clearly displayed warning signage reinforces approved isolation procedures and encourages safe working practices before any maintenance work begins.

The INVERTER Warning Dual Supply Isolate AC And DC Before Carrying Out Work Sign supports safe operation and maintenance of photovoltaic systems by clearly communicating dual supply hazards and correct isolation requirements. It assists solar installers, electricians, facilities managers, maintenance engineers and health and safety professionals in supporting compliance with the Electricity at Work Regulations 1989, the Health and Safety at Work etc. Act 1974, BS 7671 IET Wiring Regulations and recognised guidance for photovoltaic installations where applicable.

Manufactured from durable, high quality materials with excellent visibility, the INVERTER Warning Dual Supply Isolate AC And DC Before Carrying Out Work Sign is suitable for both indoor and outdoor use. It provides a long lasting and professional solution for identifying critical electrical hazards, helping improve maintenance safety, reduce the risk of electrical accidents and support the safe management of solar PV installations.
