Single Phase / Dual MPPT high efficiency inverter for residential applications. The Delta RPI Series offers Ultra-wide operating voltage range from 100-550V allows greater flexibility in string configuration. Even under harsh environmental conditions, the wide MPPT range makes it easy to configure PV arrays to stay within the maximum power operating range.
Delta’s warranty is backed by the world’s largest power electronics company and a global leader in electronics manufacturing.
High Efficiency Performance – Class-leading efficiency up to 97.5% for 3-5kW systems, using advanced transformerless topology developed by Delta, the global leader in power electronics.
Wide Working Voltage Range – Dual Maximum Power Point Trackers
Asymmetrical Loading – Symmetrical and asymmetrical loading can be supported, for greater design flexibility and performance. The ability to handle unbalanced DC inputs allows different sized strings to be configured without compromising the system performance.
Passive Cooling – Innovative heat-sink design for passive cooling reduces the operating temperature of the inverter through a natural convection process, eliminating the need for fan and filter maintenance. The enhanced cooling helps to protect sensitive electrical components and extends the life of the inverter.
Power Limiting – AC/DC Safety Switch – To ensure safety during installation, the inverter is equipped with a mechanical AC/DC switch that is designed to manually disconnect both AC and DC power sources simultaneously. At this point, the inverter is completely powered off to prevent the possibility of electric shock.
High Quality Design – Revolutionary light and compact design, with a robust die-cast case to ensure quality and durability. Not plastic. Each inverter satisfies IP65 protection level and rigorous reliability testing, such as highly accelerated life testing (HALT).
Power Quality – Various active and reactive power factor modes. Constant cos (ϕ) is the most common setting for Australia.
