  1 Overview

  For large-scale photovoltaic power generation systems, in order to reduce system wiring and improve system reliability, it is necessary to use an AC combiner box between the inverter and the grid-connected cabinet. The user can determine the model of the AC combiner box based on the input current designed by the grid-connected cabinet and the current output by the grid-connected inverter. In addition to the traditional AC convergence function and lightning protection function, our company's AC combiner box can monitor the voltage, current and power of each channel to facilitate user networking.

  7, application areas

  Large photovoltaic power station

  In large-scale photovoltaic power plants, there are still many connections between inverters and grid-connected cabinets. The use of AC combiner boxes between them can reduce system wiring and improve system reliability. The communication interface is also convenient for photovoltaic systems.
