APsystems

APsystems products for every photovoltaic requirement

APsystems is one of the world's leading manufacturers of microinverters and offers sophisticated solutions for virtually any system size. From compact balcony systems with a single module to commercial rooftop installations with dozens of panels, the product range covers all applications. At PV-24, you can find the complete APsystems product range at attractive prices with a price-match guarantee.

From single-phase microinverters like the EZ1 for quick entry into the field to three-phase models in the QT2 series for demanding projects, the right device is available for every requirement. The product range is complemented by ECU gateways for system monitoring, the EMA monitoring app, and a comprehensive selection of cables.

APsystems consistently relies on microinverter technology, where each solar module has its own dedicated inverter. This concept maximizes energy yield, as shading or soiling of individual modules does not affect the entire system. At the same time, operational reliability is increased because there is no central point of failure.

From balcony power plants to commercial facilities with APsystems

The APsystems EZ1 microinverter was specifically designed for mini-PV systems and balcony power plants . With integrated Wi-Fi and Bluetooth, the device connects directly to your smartphone without the need for an additional gateway. Setup takes only a few minutes and requires no specialist personnel.

For larger residential complexes, the DS3 series, with two MPPT inputs and an efficiency of 97%, offers a powerful alternative. Two modules are operated on a single APsystems inverter, significantly reducing installation time and material costs. The DS3D variant doubles this capacity to four modules per unit, making it ideal for multi-family homes.

Commercial installations benefit from the three-phase QT2 microinverter with symmetrical feed-in across all three phases. Four modules can be connected to each QT2, while the QT2D version can even process eight modules simultaneously. Whether you're looking for a small balcony power plant or a large-scale commercial installation, you'll find the right APsystems configuration at PV-24.

Intelligent plant monitoring with the EMA app from APsystems

The APsystems EMA app enables real-time, module-specific monitoring of your entire solar power system. Performance data, yield figures, and potential malfunctions are displayed individually for each module. This allows you to immediately see whether all components are working optimally or whether a module needs cleaning.

Data transmission is handled by APsystems' ECU gateways. The ECU-B unit collects measurement data from all connected microinverters via Zigbee and forwards it to the cloud via WLAN. The extended ECU-C version additionally offers AC and DC monitoring as well as integrated backfeed limiting for larger installations.

The cloud-based EMA platform stores all yield data long-term and generates automatic reports. Error messages are sent directly to your smartphone via push notification. Suitable microinverter accessories such as current transformers and antennas complete the monitoring system.

Modular system for flexible expansion of your PV system

A key advantage of APsystems microinverters lies in the modular expandability of each system. New solar modules can be added at any time without having to replace existing components. Each additional module simply receives its own microinverter and is automatically integrated into the existing system.

This flexibility makes getting started particularly economical. You can begin with a compact APsystems EZ1 balcony power plant and gradually expand your system to a full rooftop installation. The various APsystems series can be combined as long as the appropriate ECU gateways are available. In conjunction with an energy management system, you can further optimize your self-consumption.

The cabling supports this expandability through standardized connectors. APsystems bus cables are available in various lengths and cross-sections, from single-phase 2,5 mm² versions to three-phase 5-core cables for QT2 installations. End caps, DC extension cables, and release tools are also available from PV-24.
