MG-AC 4/1 AC Combiner Box

• MG-AC4/1 AC PV combiner box is applicable to the PV group on power system. It is an important part to undertake series inverter and AC power distribution cabinet or a step-up transformer and access up to four sets of photovoltaic group on inverter.
• Into line with the input of circuit breaker and output line with circuit breaker or the load isolating switch. Busbar with two levels of lightning protection. Highest rated system voltage is AC 690V. IP65 Protection class same as inverter Installed outdoor. With waterproof, dustproof, anti UV, anti salt spray corrosion etc function.The combiner box greatly simplifies the connection between series inverter and AC power distribution cabinet or boost transformer. Simple and clear intemal structure make reasonable wiring.
• High reliability and simple maintenance. Outdoor wall mounted can adapt to the harsh environment.
• In addition to the material and size, it can be customized according to user requirements.
