Three Phase PV Combiner Box 100kW-2000kW Solar Panel Distribution Box
Three Phase AC/DC On-Grid PV Combiner Box For 100-2000 kW PV System
On-grid PV Combiner Box plays a vital role in connecting the photovoltaic array to the grid, converting power, ensuring system safety, and enabling measurement and monitoring. It provides essential support for the efficient and reliable injection of photovoltaic power into the grid.
YTBWG on-grid PV Combiner Box primarily designed for high-power commercial and industrial photovoltaic grid-connected systems ranging from 100 kW to 2000 kW. It is connected between the grid-tied inverter (or AC combiner box) and the grid. The product features a range of protections, including anti-islanding protection, voltage detection for closing, undervoltage trip, low grid voltage, overvoltage protection, input lightning protection, system overcurrent, and grid isolation. The multifunctional meter display and fault status indication provide clear visibility of the system's operational status. The product has obtained industry-standard CCC certification and IS09001 quality management system certification.
