The protection level of the AC combiner box reaches IP65, meeting the requirements for wall-mounted sealed cabinets for outdoor installation.
Meets the requirements for connecting multiple string inverters simultaneously. Each input circuit uses a thermal-magnetic circuit breaker for protection, with a rated voltage up to AC690V.
Uses dedicated high-voltage surge arresters to meet overvoltage and lightning protection requirements between three phases, with operating voltage reaching above AC480V.
All busbars inside the enclosure use plated or purified busbar connections to reduce busbar internal resistance and connection resistance.
Output uses circuit breakers, load disconnect switches, or fuse outputs.
