Solar PV System Needs Surge Protection

Surge protection devices help keep systems running smoothly and profitably. Solar arrays are just like electronic devices that we use. These are prone to surges in voltage that can harm its components, reducing its purpose to convert energy.

Power surge significantly happens when more voltage comes through wires into devices. Some reasons include electrical overload, faulty wirings, lightning strikes and restoration of electricity after an outage. A harmful incident can occur, and in the worst case scenario, may lead to burning of the establishment. 

Solar arrays are electronic devices that are also prone to damage from surges. Solar panels are prone to lightning due to its large surface area and placement in exposed locations. These are mostly mounted in open spaces.

If the solar panels are struck directly, severe damage happens. Lightning burns holes in the equipment and even causes explosions. Loss of a PV module will only mean a loss of a string. But loss of inverter is a loss of the power generation for a large section of the plant. The effects of lightning and other overvoltage are not always apparent. These events not only affect and destroy major modules and inverters, but also monitoring systems and tracker controls.

A surge protector prevents damage to electronics by diverting the overvoltage from the power line into a grounding wire. Random and unexpected failure of solar arrays due to surges could slow down financial return. Installing surge protection device networks throughout the solar array’s DC and AC distribution protects the system from critical surges.

SPDs have its certain limitations too. For example, SPD can not prevent damages from direct lightning strikes. Adding lightning protection device can be taken to further protect the system specifically from lightning.

Lightning Protection System for Diamed Enterprise

Diamed Enterprise Lightning Protection System

May 11, 2022 – PowerPro successfully designed, supplied, and installed a Cirprotec Lightning Protection System for Diamed Enterprise located in Santa Fe Subdivision, Batong Malake, Los Baños, Laguna. The package includes a Nimbus® 15 ESE Lightning Protection Rod, providing a protection radius of at least 51M. It guarantees overall building protection from lightning strikes. Diamed, a biomedical institute, needs the security from external electrical hazards like lightning strikes. LPS preserves the condition of their equipment resulting in quality and accurate results to its customers and stakeholders. 

A CDR-401 discharge counter from Cirprotec was also installed. It features a clip-on mounting system which enables ease of installation to either flat tapes or the down conductors of the system. Unlike other discharge counters available, Cirprotec’s CDR-401 are more portable and easy to transfer without requiring any destructive work. It is also IP67 rated, making it totally protected against dust and immersion.

A grounding system completes this package to safely discharge any lightning charge that has been caught by the LPS. This includes down conductors where the lightning charges will travel to the ground, a grounding rod which will discharge the electric charge caught, and a ground inspection pit for the ease of inspection and maintenance of the ground discharge system.

With Cirprotec LPS, Diamed Enterprise is guaranteed safe from lightning damage to both their structure, electrical system, and their plugged-in delicate devices. The enterprise invested wisely in Cirprotec Lightning Protection System, making sure that the business runs smoothly and  is secure from external electrical hazards. Safety and security surely make Diamed Enterprise perform the most advanced researches and provide cutting-edge technology.
