Solar Photovoltaic (PV) systems have, over the last 50 years, evolved into a mature, sustainable and adaptive technology. The installations and demand for PV systems increase the need for effective electrical protection. PV systems, as with all electrical power systems, must have appropriate overcurrent and overvoltage protection.
PV systems, as with all electrical power systems, must have appropriate overcurrent protection for equipment and conductors. Globally there is a push for utilizing higher voltages (trending to 1000Vdc and above) to achieve more efficiency. This will mean an even greater need for circuit protection in the future.
The main overcurrent protection OCP devices used in the RV and off-grid solar power system are: – fuses and breakers -bypassing and blocking diodes Other devices like junction boxes, combiner boxes, pass-through boxes AC, and DC load centers also act as overcurrent protection devices among many other roles that they play in the solar power system.
PV systems, as with all electrical power systems, must have appropriate overcurrent and overvoltage protection. Eaton has worked closely with solar system manufacturers and through coordinated research and development, has produced revolutionary new fuse links which, combined with its combiner box, offer complete protection for PV systems.
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.
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.
Arc fault protection is a good example of a safety measure that effectively reduces the risk of fire, without compromising other safety aspects.
