Compact, dual-module design for efficiency

The DS3 Microinverter connects to two solar panels simultaneously, cutting installation time and cost in half compared to single-module microinverters. Each input channel features independent Maximum Power Point Tracking (MPPT) for optimized performance under shading or mismatch conditions. With power output options up to 880 VA, the DS3 easily adapts to high-capacity PV modules used in modern rooftop systems.

Advanced safety and compliance

Designed for the latest safety standards, the DS3 meets UL 1741 SB, IEEE 1547, and NEC 2023 requirements, including built-in rapid shutdown and arc-fault circuit protection. Its Type 6 enclosure ensures protection from dust and water ingress, making it ideal for outdoor installations in diverse climates.

Smart monitoring and communication

The DS3 features secure encrypted ZigBee communication with APsystems’ Energy Management Analysis (EMA) platform, providing 24/7 system access via web or mobile app. Users can monitor performance in real time, perform remote diagnostics, and optimize energy output for every module pair.

Reliable, silent, and long-lasting

Built with high-frequency galvanic isolation and silicone-encapsulated electronics, the DS3 achieves excellent heat dissipation and long-term durability. Natural convection cooling eliminates the need for fans, reducing mechanical wear and ensuring silent operation. With fewer components than previous generations, the DS3 offers increased reliability and extended service life backed by a 25-year warranty.
