Over the last 50 years, solar PV systems have evolved into a mature, sustainable and adaptive technology. The unique nature of PV system power generation necessitates the need for new and effective electrical protection products for overcurrent, overvoltage and isolation events.
There are mainly two kinds of these devices, AC and DC solar SPD. A solar AC surge protection device is connected to the AC side of the solar installation, between the inverter and loads. This type of SPD cannot be used on the DC side of the system as it is only designed to work with AC voltage.
A solar DC surge protection device is connected to the DC side of the solar power installation, between the inverter and the array or panels. DC SPD for solar systems works by diverting any excess voltage to the ground, thus protecting the solar panels from damage during an overvoltage by a lightning strike or other overvoltage.
The SPD price is a key factor to consider when selecting the right SPD for your needs, as you will need more than a single unit of these devices in your solar power system. Solar SPDs typically range in price from $50 to $300. The surge protection device price will depend on the features and specifications of the SPD.
As the installations and demand for PV systems increases, so does the need for effective electrical protection. PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors.
The Bussmann range of PV surge protective devices (SPDs) provides complete system protection with PV ADVANCE to suppress lightning current and PV PRO or PV HEAVY DUTY to suppress overvoltage events. Together, they protect the DC voltage section of a PV system. Max.
