Maximize Operational Efficiency with the

QS2 single-phase Quad

The cost-efficient, flexible, and safe microinverter solution for residential and small-to-medium commercial rooftops — built for the latest generation of high-power PV modules.

Driven by innovation in solar energy transformation, the APsystems QS2 single-phase quad microinverter is purpose-built for distributed solar applications. With 4 MPPTs, it delivers greater power generation capacity reaching 1920VA AC output and combines key advantages—safety, reliability, high efficiency, flexibility, and intelligent management. The components are encapsulated with silicone to reduce stress on the electronics, facilitates thermal dissipation, enhance waterproof properties, and ensure maximum reliability of the system via rigorous testing methods including accelerated life testing. A 24/7 energy access through apps or web-based portal facilitate remote diagnosis and maintenance. The new QS2 is interactive with power grids through a feature referred to as RPC (Reactive Power Control) to better manage photovoltaic power spikes in the grid.

APsystems is #1 global multi-platform MLPE solution provider, offering microinverter, energy storage & rapid shutdown devices for the solar industry.

🔎 APsystems Tech Explained: what makes MLPE differ 🔎 APsystems Tech Explained: what makes MLPE different?

MLPE, short for Module-Level Power Electronics, places power inversion, optimization, monitoring and rapid shutdown functions directly on each solar panel, enabling fully granular, panel-by-panel management and precise system control.

With independent module-level MPPT, every panel tracks its unique maximum power point separately. If shading, orientation gaps or module aging drag down one panel’s output, the rest operate without interference to maximize overall energy yield. ☀️

MLPE also delivers safer, smarter solar operation: it cuts high-voltage DC hazards, supports panel-specific monitoring and instant fault pinpointing to streamline routine O&M.

For 16 years, APsystems has specialized in MLPE innovation, delivering solar systems that are safer, more productive and far simpler to manage.

Before APsystems microinverters power your system, Before APsystems microinverters power your system, they pass multiple rounds of rigorous testing.

🌦️ Cold. Heat. Water. Salt spray.

Laboratory testing verified stable operation of APsystems microinverters across temperatures from −40°F to 149°F (−40°C to 65°C). IP67 water protection remained effective after one hour of immersion at a depth of approximately 3.3 feet (1 meter), while corrosion resistance testing further verified performance in demanding salt-spray environments.

For installers, partners, and project customers, long-term confidence begins with evidence. Here, that evidence comes test by test, across the conditions that shape real-world performance.

A solar project years in the making is now helping A solar project years in the making is now helping the Ronald McDonald House of Southern Colorado reduce its electric costs by nearly two-thirds.
 
Planning began in November 2023, and after an incredible community effort, the $300,000 project was completed in June 2026. The system includes 196 solar panels, two inverters and 108 APsystems rapid shutdown devices, with every component and service made possible through donated products, labor, materials and funding.
 
APsystems was honored to contribute rapid shutdown devices to help support a safe and reliable installation. Most importantly, the energy savings will allow Ronald McDonald House Charities of Southern Colorado to redirect more resources toward the families it serves.
 
Solar can do more than run a building. It can help power a community.
