The patented inverter thermal management and packaging approach enables the inverter to be cooled by natural convection using very little heat sink material, resulting in a small and light-weight enclosure. This inverter is the only kW-scale inverter with a NEMA 6/IP67 environmental protection rating, one enabling factor supporting the extreme product longevity.
A commercial or utility scale system based on MACRO-MICRO inverters is comprised of distributed PV string to polyphase AC inverters, with intra-array-field power collection at voltages up to 600Vac.
"MACRO-MICRO" is an allegorical reference to a "microinverter" approach scaled and optimized for use in systems from 17kW to multi-megawatts.
RPC's proprietary inverter power topology has achieved the highest CEC efficiency of any 10kW-20kW inverter at 98%.
