Efficiently designing PV and storage projects demands smart hardware that minimizes on-site mounting time and reduces the bill of materials per Watt-peak. With the latest generation of dual- and quad-microinverters from APsystems, professionals combine maximum energy yield per panel with significantly fewer rooftop steps.

To meet ongoing international demand, the popular [DS3 series ](https://www.estg.eu/en-gb/brands/apsystems?system=APS%20DS3%3BAPS%20DS3-H%3BAPS%20DS3-L)and the [3-phase QT2](https://www.estg.eu/en-gb/p/124056/apsystems-qt2eu-microinverter) are fully stocked and available for immediate dispatch.

## Why choose dual- and quad-microinverters?

Dual- and quad-microinverters from APsystems connect two to four solar panels to a single unit on the roof. This cuts the required number of inverters in half, significantly reduces AC cabling and mounting accessories, and ensures maximum safety by converting direct current (DC) to alternating current (AC) directly at the panel level.

Integrating multi-panel microinverters provides immediate operational and financial advantages for both residential and commercial projects:

- **Faster mounting on site:** Fewer enclosures to secure and less cabling required per Watt-peak.
- **Independent MPPT per panel pair:** Maximum energy yield on complex or shaded roofs through isolated Maximum Power Point Tracking.
- **Enhanced rooftop safety:** Direct AC conversion eliminates high DC voltage risks and arc fault hazards.

## Native 3-phase coupling without phase imbalance: the APsystems QT2

The APsystems QT2 is a native 3-phase quad-microinverter that connects four solar panels and feeds power evenly across three phases (400V). This eliminates phase imbalance in the distribution board for commercial buildings and larger residential projects.

With high input current capabilities, the QT2 seamlessly handles high-capacity N-type and Bifacial modules up to 670Wp+ without clipping losses.

## APsystems microinverters available directly from stock

The complete DS3 series (DS3-L, DS3, DS3-H) and the 3-phase QT2 are in stock and ready for immediate dispatch across all your active and upcoming projects.

## Frequently asked questions (FAQ)

- **What is the advantage of a native 3-phase microinverter like the APsystems QT2?**The QT2 distributes power from four solar modules evenly across all three phases, preventing phase imbalance on the main grid connection without requiring external phase-balancing devices.
- **Are APsystems microinverters compatible with high-wattage modules above 600Wp?**Yes. Both the latest DS3 models and the QT2 feature high input current ratings, making them fully compatible with modern high-capacity N-type and Bifacial PV modules without clipping losses.
- **Can APsystems microinverters be integrated into energy storage systems?**Yes. Because microinverters convert power to AC at the module level, they integrate seamlessly into AC-coupled battery storage systems and HEMS environments.
