Overview of the products

DC surge protectors are mainly used on the current lines between the battery pack and inverter in centralized photovoltaic power generation systems; AC surge protectors are mainly used in centralized photovoltaic systems for AC lines between inverters and power distribution panels, between power distribution panels and AC loads and between the low-voltage sides of box transformers. For string photovoltaic power generation systems, AC surge protectors are mainly used to protect the AC lines between inverters and AC combiner boxes, as well as between the AC combiner box and the low-voltage side of the box transformer.
