Application of AC Combiner Box in Distributed Photovoltaic Industry
2023-07-20
The role of the AC combiner box: The AC combiner box is suitable for photovoltaic string power generation systems. The incoming and outgoing lines of this combiner box adopt circuit breakers and adopt secondary lightning protection protection. The installation requirements meet the requirements of waterproof, dustproof, UV protection, salt spray corrosion protection, etc.
This product is used in photovoltaic power generation systems using string inverters. It is installed between the AC output side of the inverter and the grid-connected point/load. The internal configuration includes: input circuit breaker, output circuit breaker, and AC lightning protection device. Optional intelligent monitoring instrument (monitoring system voltage, current, power, electric energy and other signals)
Converge the output current of multiple inverters, and at the same time protect the inverters from harm from the AC grid-connected side/load, and serve as the output disconnection point of the inverters to improve the safety of the system and protect the safety of installation and maintenance personnel.
Features of AC combiner box
①The voltage covers a wide range and can be used with inverters of different voltages from AC400V to AC690V;
②Light weight, small size, easy installation, beautiful appearance;
③The protection grade is IP65, which meets the requirements for indoor and outdoor installation;
④ Standard four-level lightning protection module, full-mode protection;
⑤ With RS485 communication interface, using ModBus-RTU communication protocol;
⑥The components of well-known domestic and foreign brand manufacturers can be used according to customer needs.
