    Photovoltaic AC intelligent combiner box

    The new PV AC Combiner boxes have been designed for PV systems with string inverters in trackers or fix tilt systems. The product portfolio is suitable for inverters from 60 kW up to 200 kW and support voltages of 400 V, 690 V or 800 V AC.


    FAQs about Photovoltaic AC intelligent combiner box

    What is a photovoltaic AC combiner box?

    The photovoltaic AC combiner box is used in a photovoltaic power generation system with string inverters and is installed between the AC output side of the inverter and the grid connection point/load. It is internally equipped with input circuit breakers, output circuit breakers, and AC lightning arresters.

    What is a PV combiner box?

    Yueqing Sandi Electric Co.,Ltd, as a major manufacturer & exporter, offers a solution for the connections and installations of PV systems through the PV combiner box. Designed to provide performance monitoring and protection for photovoltaic systems.

    How many string inverters can a combiner box collect?

    The combiner boxes allow to collect from 2 up to 6 string inverters in one single cabinet. They withstand ambient temperatures from -20 up to +50°C to operate in hardest climate conditions, fulfilling the highest market standards as per IEC 61439-2 ed 3.0:2020.

    How are PV AC combiner boxes tested?

    Our PV AC combiner boxes are tested according to IEC-61439-2 ed 3.0:2020 and are constructed on the basis of the test results as well as assembled for the specific application. This ensures that each of the requirements of the target application is fully met.

    How many inverters are in a 400v/50kw AC combiner box?

    Taking the AC combiner box with 4 in 1 (400V/50KW) as an example, there are a total of 4 inverters of 50KW: Label 1: The output end of the inverter is directly connected to the 4P circuit breaker. The circuit breaker can quickly cut off the fault current. The maximum AC output current of the inverter is 80A.

    Can a string inverter be isolated from a PV system?

    Furthermore, each string inverter can be easily isolated from the system to do maintenance tasks. The new PV AC Combiner boxes have been designed for PV systems with string inverters in trackers or fix tilt systems.The product portfolio is suitable for inverters from 60 kW up to 200 kW and support voltages of 400 V, 690 V or 800 V AC.
