APsystems Microinverters for Modern Solar Systems

Explore the APsystems collection at Portlandia Electric Supply, where advanced microinverter technology meets long-term reliability for residential and commercial solar setups. This trusted name designs scalable, high-efficiency equipment that enhances energy harvest with strict safety and grid-compliance. Whether upgrading or new building, microinverters like DS3, QS1, and QT2 series provide performance, flexibility, and easy installation.

Why Choose Microinverters?

Microinverters convert solar energy efficiently by giving each panel its own power-processing channel. This means better system resilience, less impact from shading, and optimized power even under varying conditions. With wireless communication and robust construction, these devices deliver reliable results.

Installers also value streamlined architecture, simplified wiring, and flexible design. Whether needing dual-module inverters for rooftops or three-phase units for commercial projects, these microinverters adapt easily.

Leading Microinverter Models & Specifications

DS3 Series (Dual-Module, Single-Phase)

The DS3 Series is a refined microinverter platform, great for high-output residential use. Models include:

• DS3-S – 640 VA
• DS3-L – 768 VA
• DS3 – 880 VA

Each DS3 has two PV modules, up to 550 Wp each, with independent MPPT channels. It uses encrypted Zigbee communication to connect securely to the ECU gateway and monitoring platform.

These microinverters comply with CA Rule 21 and NEC 2020 Rapid Shutdown. Their compact, silicone-encapsulated housing reduces thermal stress and boosts waterproofing for longevity.

QS1 Series (Quad-Module, Single-Phase)

The QS1 connects up to four solar modules with four independent MPPT channels. It delivers 1,200 W output for high-power residential and small commercial systems.

It cuts the number of microinverters needed per project, reducing installation time and BOS costs. It supports Zigbee communication and meets NEC 690.12 Rapid Shutdown for safety and compliance.

QT2 Series (Three-Phase, Commercial Applications)

The QT2 is designed for large arrays needing three-phase output. Key traits include:

• Up to 1,728 VA continuous output
• Peak efficiency of 96.5%
• MPPT efficiency of 99.5%
• Built-in encrypted Zigbee communication
• IP67 rating for harsh weather conditions

The QT2 excels in durability, monitoring, and reliability. Its scalable design suits warehouses, schools, retail, and multi-inverter fields.
