Surge Protector Solar Panel

Mounting the surge protector on the main panel box step 1.

Surge protector solar panel.

Solar needs surge protection. Flathead screwdriver and screws. Raycap is a leading producer of surge protection devices for photovoltaic pv systems that are used in both industrial power production as well as residential or semi commercial markets. Here s a list of tools needed to install a main panel surge protector.

Solar panels and their associated control systems are highly susceptible to damage from both direct and indirect lightning strikes. Devices known as surge protectors spd or transient voltage surge suppressors tvss connected to these conductors can route these transient currents to the ground protecting the equipment from damage. The abb low voltage products division has released a line of ovr pv ul 1449 3rd edition pluggable dc din rail surge protection devices spd specifically designed for photovoltaic applications. Surge protectors should be installed at both ends of any long wire run that is connected to any part of your system including ac lines from an inverter.

Surge arrester is a voltage limiting device installed inside the installation equipment panel to protect the insulation equipment and machines not only from lightning but also from transient voltage produced by switching sparks load shading and other electrical faults such as ground faults etc. A surge protector works by momentarily switching from an open circuit mode into a low impedance mode and shunting the surge energy to the ground limiting the overvoltage to a safe level in the process. Surge arresters are used to limit the current and voltage surges to protect the low and high voltage appliances as well as communication lines. Be sure to use the appropriate arrestors for your application.

The new spds will protect solar panels from damage from direct and indirect lightning strikes which solar panels are especially susceptible to because of their large fully exposed surface areas and prevalent installations in open. In most common surge protectors this is achieved through a metal oxide varistor mov a piece of metal oxide joined to the power and grounding lines by two semiconductors. These surges may result in the destruction of delicate electronics and semiconductors. Surge protection photovoltaic wind and hydroelectric systems usually have long runs of exposed wire that can pick up surges from lightning even if the lightning strike is not nearby.

Each provides small easy to install surge protection for the entire home or office. When the surge event is over the protector returns to its open circuit mode ready for the next event. By kathie zipp march 7 2013. Lightning and surge protection for solar panels.

Surge protection for solar panels. Turning off the main power. A surge protector helps prevent damage to electronics by diverting the extra electricity from the hot power line into a grounding wire. The protectors consist of multiple metal oxide visitors with internal thermal and overcurrent protection.

These power surges can damage sensitive electronic components in meters charge controllers and inverters.
