Solar street light system is now widely used in varies countries and territories. It is easy installation, flexible, stable and long life time. The solar street light is typically consisted by solar panel, junction box, inverter, led street light, battery and control system, etc. A lot of electrical/electronic devices are integrated in a.

Why do solar panels need a lightning arrester?
Lightning arresters protect solar panels against lightning and protect the complicated circuitry of inverters, charge controllers, etc. These components are easy prey for lightning power surges.
Lightning (surge) arrestors are designed to absorb voltage spikes caused by electrical storms (or out-of-spec utility power), and effectively allow the surge to bypass power wiring and your equipment.
What causes lightning damage in solar street lights?
Accept for ESD improper bonding, grounding or transient protection is the leading cause for lightning damage. The solar street light comes equipped with a single needle lightning rod which provides the light with proper grounding against direct lightning strikes.
If the surge current exceeds the breakdown voltage of the spark gap, then the metal oxide disc takes over and provides additional guard. This is the most common and traditional kind of lighting arrester for solar systems. A metal rod or tube, usually made of copper or aluminium, is suspended on tall buildings or structures.
What are the different types of lightning arresters for solar panels?
Here are seven types of lightning arresters for solar panels, A copper lightning arrester is made up of a copper-bonded rod with around 45 or five spikes on top. Voltage spikes from electrical storms are absorbed by it and allowed to pass through the solar system, electrical wiring and any other household devices.
SunMaster solar street light provide the professional lighting rod and earthing rod to prevent the direct lighting. Single needle lightning rod: Single needle lightning rod of the lightning protection function is that it can receive the lightning and lead the lightning down to the earth invitiatively.
