APsystems’ 3
rd
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 series 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. A 24/7 energy access
through apps or web based portal facilitate remote diagnosis and maintenance.
The DS3 series is grid-interactive and fully compliant with CA Rule 21 requirements. With its unparalleled performance,
efficiency of 97.3%, and increased reliability, the APsystems DS3 series is a gamechanger for residential and commercial
solar.
