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.

2 sets of MPPTs optimize power harvesting from multiple
arrays oriented in different directions. The inverter will track
the optimal power point for each of the two arrays independently. Both inputs can be combined and used with a single
array as well.
