APsystems DS3-S 640W Microinverter

APsystems’ 3rd generation of dual-module microinverters, the DS3-S 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-S reaches unprecedented levels of power output and 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.

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