2024/02/22 Rev2.0 <br />PRODUCT FEATURES <br />WIRING SCHEMATIC <br />DS3 Series <br />The most powerful Dual <br />Microinverter <br />• One microinverter connects to two solar modules <br />• Max output power reaching 640VA, 768VA or <br />880VA <br />• Two independent input channels (MPPT) <br />• CA Rule 21 (UL 1741 SB) compliant <br />• NEC 2020 690.12 Rapid Shutdown Compliant <br />• Encrypted Wireless ZigBee Communication <br />• Phase Monitored and Phase Balanced <br />APsystems’ 3rd generation of dual-module microinverters, the DS3 product family represents the culmination of years <br />of power conversion expertise and innovation in high-efficiency, high-density power conversion to maximize the peak <br />performance of today’s high-capacity PV modules. <br />The DS3 series reaches unprecedented levels of power output. It features 2 input channels, each with independent MPPT, <br />and encrypted wireless ZigBee communication. An innovative and compact design makes the product lighter while <br />maximizing power production, and silicone-encapsulated components reduce stress on electronics, facilitate thermal <br />dissipation, and enhance weatherproofing. Reliability is significantly increased thanks to 20% fewer components than <br />previous generations. A 24/7 energy access through apps or web based portal facilitate remote diagnosis and maintenance. <br />The DS3 series is grid-interactive and fully compliant with CA Rule 21 requirements. With an excellent performance and <br />high converstion efficiency, a unique integration with less components, the APsystems DS3 series is a gamechanger for <br />residential and commercial solar. <br />Leading the Industry in <br />Solar Microinverter Technology <br />Region <br />Model <br />USA Canada <br />Datasheet | DS3 Microinverter Series <br />Mechanical Data <br />Operating Ambient Temperature Range(3)-40°F to +149°F (-40°C to +65°C) <br />Storage Temperature Range -40°F to +185°F (-40°C to+85°C) <br />Dimensions (W x H x D) 10.3” × 8.6” × 1.6” <br />(263mm x 218mm x 41.2mm) <br />10.3” × 8.6” × 1.7” <br />(263mm x 218mm <br />x 42.5mm) <br />Weight 5.7lbs(2.7kg) 6.8lbs(3.1kg) <br />DC Connector Type Stäubli MC4 PV-ADBP4-S2&ADSP4-S2 <br />Cooling Natural Convection - No Fans <br />Enclosure Environmental Rating Type 6 <br />Efficiency <br />Peak Efficiency 97.3% <br />CEC Efficiency 97% <br />Nominal MPPT Efficiency 99.5% <br />Night Power Consumption 20mW <br />Features <br />Communication (Inverter To ECU) (4)Encrypted ZigBee <br />Isolation Design High Frequency Transformers, Galvanically Isolated <br />Energy Management Energy Management Analysis (EMA) system <br />Warranty(5)10 Years Standard ; 25 Years Optional <br />Compliance <br />Safety and EMC Compliance UL1741; CSA C22.2 No. 107.1-16; UL1741SA; UL1741SB; <br />IEEE1547; Rule 21; SRD-V2.0; FCC Part15; ICES-003; <br />NEC2014&NEC2017&NEC2020 Section 690.11 DC Arc-Fault <br />circuit Protection; NEC2014&NEC2017&NEC2020 Section <br />690.12 Rapid Shutdown of PV systems on Buildings <br />APsystems <br />8627 N.
