Delta’s industrial cutting-edge technology presents the industrial leading efficiency as high as 98.2% and durable quality PV inverter to ensure your PV system operation. LCD Graphical display IP65 Protection / Transformerless Design AC Output Ergonomic grip Design DC Input x 4 strings RS485 DC Switch Swappable Fan Kit High Quality Enclosure Convection cooled aluminum housing is desinged with 2 separate compartments for electronic components and air cooling purposes in order to emit the heat more efficiently. IP65 rated enclosure and corrosion resistant features ensure the inverter protection in both indoor and outdoor environment. DC input adopts the MC4 fast connects which allows easy plug in during installation. Flexibility in rooftop / ground applications Delta RPI-Commercial 3 phase PV inverter is designed in string inverter concept by having compact sieze with high level IP65 protection. It is flexible in rooftop solar solution without limited by obstacles on rooftop, and also in larget scale solar power plant site. More flexibility is given to site planning, construction & maintenance due to RPI-Commercial PV inverter’s compact size and light weight. With IP65 protection level, it can be simply placed behind the solar panel on the system rack without taking any extra space. Easy Installation & Swappable feature Installation of RPI-Commercial series is easy and safe with fast plug connection design. This helps to speed up the installation and save the installation costs. The unit has vertical die-casting cooling heat sink and additional cooling fan module below enhance air circulation, bringing down the unit temperature to maintain system performance. Cooling fan module below inverter is designed with easy swappable feature. User can simply unscrews and withdraw the cooling fan module to replace single fan if necessary. Smart Communication & Logger 5” LCD brings all the relevant system information and settings in graphics display. Easy to use push button interface to access all important data stored inside the built-in data logger. Logger will automatically save the electricity information generated by solar system in several periods of time. Power generation record every 5 minutes will be saved for one day. Power generation record every 15 minutes will be saved for one month. Daily total power generation info will be saved in the system for one year. Monthly total power generation info will be saved in the system for 10 years.
