Product Detail


The 40kA DC Surge Protector for Solar System Protection specially designed to protect solar energy systems from surges and transient voltage spikes on the DC (direct current) side. It helps protect solar panels, inverters, charge controllers and other DC equipment from potential damage caused by electrical interference. Certifications such as UL 1449 or IEC 61643 ensure that the device has been rigorously tested and meets the necessary protection requirements. DC surge protectors have a limited lifespan because they absorb and dissipate energy during a surge event. Regular maintenance and regular inspections are recommended to ensure the effectiveness of the equipment.
