Eaton’s Electrical Sector will be offering visitors to next week’s Intersolar Europe event the chance to find out about its complete package for the safe operation of residential and commercial photovoltaic (PV) installations. On the stand, visitors will be able to see the full scope of Eaton’s PV products, such as its power inverters and its DC switch disconnector range which includes the company’s innovative fireman’s switch. Experts from Eaton will also be on hand to talk to visitors about how the solutions it offers can meet their specific application needs.
In the event of a fire, rescue personnel can be at risk of electric shocks due to damaged cable insulation. Even in reduced daylight, the cables between PV modules and the power inverter are energised with voltages of up to 1000V. Subsequently, accident prevention regulations stipulate that residential buildings that have not been isolated from the power supply must not be entered for indoor fire fighting making it difficult for fire crews to manage and stop the fire effectively. Eaton’s innovative fireman’s switch, SOL30-Safety, offers a solution by enabling remote disconnection of the DC power source on the outside of a building ensuring no electricity is present internally, thus allowing fire crews to enter the building and fight the fire from the inside.
As well as the fireman’s switch, visitors to Eaton’s stand will be able to see the rest of Eaton’s comprehensive family of PV balance-of-system products. These include power inverters for converting the DC current of PV generators into AC current, compact dc switch disconnectors for isolating PV panels during maintenance, dc string fuses and circuit breakers to provide dependable protection for the PV installation, and both dc and ac overvoltage protection.
