APsystems DS3 880W Dual-Module Microinverter 117211

The APsystems DS3 117211 is a high-performance dual-module microinverter designed to connect and independently optimize two solar modules. As part of APsystems' third-generation DS3 platform, it combines dual independent MPPT channels, high conversion efficiency, encrypted wireless communication, and advanced rapid-shutdown compliance in a compact grid-interactive inverter.

With a 97.3% peak efficiency, 97% CEC efficiency, and 99.5% nominal MPPT efficiency, the DS3 is engineered to maximize module-level energy harvest. It also supports both 208V and 240V AC systems, encrypted ZigBee communication with an APsystems ECU, and monitoring through the APsystems Energy Management Analysis platform.

Key Technology

• 880VA Dual-Module Microinverter
  Provides up to 880VA maximum continuous AC output while connecting two photovoltaic modules to one microinverter.

• Two Independent MPPT Channels
  Each connected solar module operates on its own independent maximum power point tracker, allowing each panel to optimize production independently.

• 300W–660W+ Module Compatibility
  The DS3 is specified for PV modules from approximately 300Wp to 660Wp+, providing compatibility with a broad range of modern high-power solar panels.

• 20A Input Current per Channel
  Each DC input supports up to 20A maximum input current, making the DS3 suitable for many newer high-current PV modules.

• 25A Short-Circuit Current per Input
  Supports up to 25A maximum PV short-circuit current per DC input.

• 208V / 240V AC Compatibility
  Designed for North American grid-connected systems operating at either 208V or 240V AC.

• 97.3% Peak Efficiency
  High conversion efficiency helps maximize the amount of DC solar energy delivered to the AC electrical system.

• 99.5% MPPT Efficiency
  High nominal MPPT efficiency enables accurate power-point tracking across varying irradiance and module conditions.

• Encrypted ZigBee Communication
  Communicates wirelessly with compatible APsystems Energy Communication Units using encrypted ZigBee technology.

• Module-Level Monitoring
  When paired with compatible APsystems monitoring hardware, production and operating data can be accessed through the Energy Management Analysis platform.

• NEC 2023 Rapid Shutdown Compliant
  The DS3 platform is identified by APsystems as compliant with NEC 2023 Section 690.12 rapid shutdown requirements. 

• CA Rule 21 / UL 1741 SB Compliance
  Designed as a grid-interactive inverter meeting applicable California Rule 21 and UL 1741 SB requirements.

• Galvanically Isolated Design
  Uses high-frequency transformers to provide galvanic isolation between the PV and AC sides.

• Natural Convection Cooling
  Fanless passive cooling reduces moving components and helps support quiet, reliable operation.

• Type 6 Enclosure
  Features a rugged environmental enclosure designed for demanding rooftop PV installations.

• 25-Year Standard Warranty
  Backed by a 25-year standard APsystems warranty, subject to manufacturer monitoring and warranty requirements.

Best Uses

• Residential Rooftop Solar
  Ideal for rooftop PV systems requiring module-level power conversion and monitoring.

• High-Power Solar Modules
  Well suited for modern modules rated up to 660W+ and requiring higher DC input-current capability.

• Roofs with Multiple Orientations
  Independent MPPT channels allow the two connected panels to operate independently when installed on different roof faces or exposed to different solar conditions.

• Partially Shaded Arrays
  Module-level conversion helps reduce the impact one shaded or underperforming panel can have on other modules in the array.

• 208V or 240V PV Systems
  Supports flexible installation on compatible North American 208V and 240V electrical services.
