About product

The most powerful Dual Microinverter.

APsystems’ 3rd generation of dual-module microinverters, the DS3 product family represents the culmination of years of power conversion expertise and innovation in high-efficiency, high-density power conversion to maximize the peak performance of today’s high-capacity PV modules.

The DS3 microinverter reaches unprecedented levels of power output of 640VA to adapt to today’s larger power module. It is fully backwards compatible with QS1 and YC600 microinverters and accessories. It features 2 input channels, each with independent MPPT, and encrypted wireless Zigbee communication. An innovative and compact design makes the product lighter while maximizing power production, and silicone-encapsulated components reduce stress on electronics, facilitate thermal dissipation, and enhance weatherproofing. Reliability is significantly increased thanks to 20% fewer components than previous generations. A 24/7 energy access through Apps or web-based portal facilitate remote diagnosis and maintenance.

The DS3 microinverter is grid-interactive and fully compliant with CA Rule 21 requirements. With its unparalleled performance, efficiency of 97%, and increased reliability, the APsystems DS3 microinverter is a gamechanger for residential and commercial solar.
