About Photovoltaic combiner box always burns surge
SPDs provide protection against the hazards caused by surges. UL 1449 defines type 1, type 2, and type 3 SPDs: 1. Type 1: One port, permanently connected SPDs, except for watt-hour meter socket enclosures, intended for installation between the secondary of the service transformer and the line side of the service.
PV systems have unique characteristics, which therefore require the use of SPDs that are specifically designed for PV systems. PV systems have high dc system voltages up to 1500 volts.
PV sources have very different current and voltage characteristics than traditional dc sources: they have a non-linear characteristic and cause long-term persistence of ignited.
SPDs should always be installed upstream of the devices they are going to protect. NFPA 780 12.4.2.1 says that surge protection shall be provided on the dc output of the solar panel.
Surge protection is just as important for the ac side as it is for the dc side. Ensure that the SPD is specifically designed for the ac side. For optimal.
