The PVX100 series photovoltaic array intelligent lightning protection busbar box has the features of meeting the requirements for outdoor installation, fully sealed design, dustproof, waterproof, antistatic, and suitable for harsh environments and low-temperature areas. It can simultaneously connect 8-24 channels of solar cell strings, with a maximum current of 15A per channel, and a maximum open circuit voltage of 1000V for the connected photovoltaic strings. It is equipped with photovoltaic-specific high-voltage lightning arrester, four-pole circuit breaker, intelligent DC acquisition, monitoring and analysis of solar cell string performance, input signal acquisition, output signal, operation data recording, remote communication, and other functions.
The PVX100 series is a fully sealed, dust‑, water‑, static‑ and temperature‑protected combiner box designed for outdoor photovoltaic installations. It integrates lightning protection, intelligent DC monitoring, and communication functions, allowing 8 to 24 PV strings (up to 15 A per string) to be safely combined before feeding an inverter.
