The smallest & lightest 50 kW string inverter in the world.
Delta’s latest revolutionary design “RPI-M50A” transformerless PV inverter is the lightest,
smallest, and first wall mount-able 50KW string inverter in the world. With such compact size and light weight, RPI-M50A offers more design flexibility for all sizes of PV plants. IP65 enclosure provides higher level of protection and enhances its durability in a harsh outdoor environment.

 

Thoughtful Grip Design
Ergonomic grip design gives more convenience while moving the inverter during installation. With special handle protection design, RPI-M50A can be easily placed down on the flat ground vertically without damaging various connectors at the bottom.

 

Built-in SPD & String Fuses
The RPI-M50A comes with built in PV fuse on both the positive and negative strings for all
twelve inputs. Also the inverter has Type-2 SPD's (Surge Protection Device) for both the
DC (One for each MPPT) and AC inputs. Both
the PV fuse and SPD's can be replaced. This
can bring down the overall PV system costing.

 

Outstanding Performance
RPI-M50A comes with a peak efficiency of 98.6 %, guaranteeing better yields and returns on capital cost. The dual MPPT trackers ensure no compromise over shading losses and can accommodate PV arrays with different orientations.

 

Protection Features : AC / DC Safety Switch
Integrated AC/DC switch makes maintenance
and trouble shooting easy.

 

Savings with RPI-M50A

  • Saving on System Cost : Holistic design with built-in AC/DC switch, PV fuse and SPD's.
  • Saving on Space Cost : Thanks to the IP65 rating of the RPI-M50A, it can be mounted outdoors thereby reducing costs associated with control rooms for central inverters.
  • Saving on DC Cable Cost : The RPI-M50A can be mounted close to the PV panels which brings down the associated DC
  • cable costs and DC cable losses which improves overall system efficiency.
  • Dual MPPTs : Two independent trackers ensure maximum yields even during partial shading of a string. This also helps in accommodating different string orientations within a system.

 

Notes

  • If PV Module is grounded (Negative / Positive Grounding), separate Isolation
  • Transformer is required at the Grid interface of Inverter
  • Parallel Operation of Inverters is possible for large Power Plants
  • For Cos phi = 1 (VA=W); 55 kVa is Possible with: DC Input Voltage 600V;
  • Symmetrical Loading; Ambient Temperature <34o C
  • Refer to Delta's Standard Warranty Terms and Conditions for more details.
