APSystems DS3-H Dual Microinverter 1050VA AC

SKU: APS-DS3-H

Mfg. SKU: DS3-H

APsystems DS3-H Microinverter

Overview

• Mounts on standard solar rails behind each panel, converting DC into clean 240 V AC for Canadian grid-tie systems.

• Two independent PV inputs optimize up to two panel strings—each string tracked separately for mixed orientations or partial shade.

Key Features & Specifications

• Dual PV Inputs & MPPT

  • Two independent MPPT channels track “sweet-spot” voltage (32 V–55 V within a 26 V–60 V operating range), harvesting up to 99.5 % of panel potential.

  • Maximum input current: 20 A per channel.

• Module Compatibility

  • Panel power range: 450Wp-730Wp+

  • Maximum open-circuit voltage (Voc): 60 V

• AC Output

  • Continuous power: 1050 VA at 240 V, 60 Hz (4.4 A nominal)

  • Adjustable power factor: ±0.8

  • Maximum units per branch: 3 on a 20 A circuit; 5 on a 30 A circuit

• Efficiency

  • Peak conversion efficiency: 97 %

  • CEC-weighted efficiency: 96.5 %

  • MPPT efficiency: 99.5 %

  • Night power draw: 20 mW

• Durability & Safety

  • Operating temperature: –40 °F to +149 °F

  • NEMA 6–rated enclosure with passive (fan-free) cooling

  • Built-in protection: over/under-voltage & frequency (UL 1741, CSA C22.2)

Installation & Monitoring

• MC4 plug-and-play connectors for fast, tool-free wiring

• ZigBee communication to APsystems EMA portal for real-time, panel-level monitoring

Mechanical Specifications

• Dimensions: 10.3″ × 8.6″ × 1.7″

• Weight: 6.8 lb

Fun Fact & Sizing Tip

• Solar panel voltage drops on hot summer days and spikes on cold winter mornings.

• Keep Voc at least 25 % below the 60 V max (aim for ~45 V) to allow cold-weather headroom and avoid over-voltage trips.

Why It’s Ideal for Canadian Solar

• Maximizes net-metering and rebate programs (Ontario, Alberta, B.C., Québec, Canada)

• Lowers energy bills by squeezing extra kWh from every panel

• Provides carbon-tax relief by generating clean power to offset Canada’s carbon levy

Support

• AP Systems North American 25 year warranty

• 24/7 technical support via phone, email, and online resources
