Compact dual-module performance

The DS3-L connects to two PV modules, delivering up to 768 VA of continuous output power while optimizing each panel’s performance through independent dual MPPT tracking. This dual-input configuration reduces component count, streamlines installation, and enhances overall energy yield, making it ideal for high-efficiency residential rooftops and small-scale commercial systems.

Reliable, efficient, and built to last

With 97.3% peak efficiency and 99.5% MPPT tracking efficiency, the DS3-L ensures maximum energy conversion under varying sunlight conditions. Silicone-encapsulated electronics improve heat dissipation and weather resistance, while a rugged Type 6 enclosure provides protection against moisture, dust, and corrosion for long-term outdoor durability.

Safe and compliant by design

The DS3-L includes integrated safety features such as rapid shutdown capability, arc-fault circuit protection, and ground fault detection, ensuring compliance with NEC 2023 and UL 1741 SB standards. Its fully isolated, high-frequency transformer design provides an additional layer of protection for both the system and installers.

Smart communication and monitoring

Equipped with encrypted ZigBee communication, the DS3-L integrates seamlessly with the APsystems Energy Management Analysis (EMA) platform for 24/7 system monitoring, remote diagnostics, and performance tracking. Installers and homeowners can access real-time data via the web or mobile app, ensuring optimal visibility and control of system performance.

Simple installation, low maintenance

The microinverter’s compact form factor and plug-and-play MC4 connectors make installation fast and straightforward. Its fanless, convection-cooled design ensures quiet operation and minimal maintenance, while the system’s phase-balanced operation enhances grid stability.
