Delta RPI M15A Flex - The Commercial String Inverter for Highest Demands
The Delta RPI M15A Flex is a high-performance three-phase solar inverter designed for demanding residential and commercial photovoltaic systems. With a rated apparent power of 15 kVA and an excellent peak efficiency of 98.4%, this inverter sets standards in its power class.
Stable Peak Performance Even at Extreme Temperatures
An outstanding feature of the Delta RPI M15A Flex is its stable performance up to 50°C ambient temperature without derating. This ensures consistent energy yields even on hot summer days. The extended operating temperature range from -25 to +60°C and the maximum operating altitude of 4,000 meters make this inverter particularly versatile.
Two Powerful MPP Trackers for Flexible System Planning
The Delta RPI M15A Flex is equipped with two independent MPP trackers, each capable of accommodating up to two module strings. With a maximum input current of 26 A per tracker and 48 A total, plus a wide MPPT range from 200 to 1000 volts DC, it offers maximum flexibility in system design. The asymmetric load distribution from 60/40 to 40/60 enables optimal yields even with differently occupied roof surfaces.
Integrated Surge Protection for Maximum Safety
The Delta RPI M15A Flex features replaceable Type 2 surge arresters on both DC and AC sides. This integrated protection function reliably secures the system against overvoltages and reduces installation effort as external protection components can be eliminated.
Convenient Commissioning and Monitoring via App
Commissioning of the Delta RPI M15A Flex is conveniently done via the DeltaSolar smartphone app through integrated Wi-Fi. The MyDeltaSolar Cloud enables professional remote monitoring and data visualization of all system parameters. Additionally, two RS485 interfaces, potential-free contacts, and six digital inputs are available for extended integration scenarios.
Robust Construction for Permanent Outdoor Installation
With IP66 protection rating and natural convection cooling, the Delta RPI M15A Flex is optimally equipped for outdoor installation. The low noise emission makes it ideal for use near residential and commercial buildings. The standby consumption of less than 2 watts during night operation minimizes losses.
Certified Quality with Extendable Warranty
The Delta RPI M15A Flex meets all relevant standards including VDE-AR-N 4105 and EN 50549-1. The 5-year standard warranty can be extended upon request and underscores the manufacturer's confidence in product quality.
