The GY-AC photovoltaic AC combiner box is suitable for use inphotovoltaic string-type power generation systems. lt is a crucialcomponent that connects string-type inverters to Ac distributioncabinets or step-up transformers. The box’s input uses circuit breakerinput, and the output uses circuit breakers or load isolation switches.The busbar is equipped with secondary lightning protection, and thesystem’s rated voltage is up to AC690V. The protection level is lP65the same as the string inverter, meeting outdoor installationrequirements, providing waterproof, dustproof, UV-resistant, and saltspray corrosion-resistant features.This product greatly simplifies thewiring between string inverters and AC distribution cabinets or step-up transformers. The internal structure is simple and clear, with neatand rational wiring. lt has high reliability, simple maintenance, and issuitable for outdoor wall-mounted installation in various harshenvironments.In addition to standard materials and sizes. it can becustomized according to user requirements.
DC Combiner Box Overview
The GY-PV DC combiner box combines up to 24 strings of photovoltaicmodules into one or more outputs.Each output is equipped with a fusewire, and the output is equipped with a lightning arrester and circuit breaker,greatly simplifying the input wiring of the DC distribution cabinet and inverter. lt provides lightning protection, short-circuit protection.and grounding protection. The combiner box is divided into inteligent and non-intelligent types. The inteligent lightning protectioncombiner box is equipped with a current monitoring unit that can monitor the current input of each string of photovoltaic modules,summarize the output voltage, the temperature inside the box, the status of the lightning arrester, the status ofthe circuit breaker, etcThe device’s internal arrangement is simple and clear, with neat and rational wiring. lt has high reliability, simple maintenance,and is suitable for outdoor wal-mounted installation in various harsh environments, in addition to core components, others can becustomized according to user requirements.
