AP Systems EZ1: The Leading Microinverter for Balcony Power Plants

Mar 2, 2026

The AP Systems EZ1 is a state-of-the-art dual microinverter, specially developed for balcony power plants and DIY systems. It efficiently connects two solar modules and maximizes energy yield through independent MPPT trackers. With its plug-and-play function, it is ideal for renters and homeowners looking for uncomplicated solar solutions.

Market Trends in Microinverters

The market for balcony power plants is booming in Germany. According to the Federal Network Agency, over 500,000 new systems were registered in 2025, many of them with microinverters like the AP Systems EZ1. The trend is towards high-performance models with higher output power up to 800 watts to accommodate increased module sizes.

Users demand smart features such as app monitoring and easy throttling. AP Systems EZ1 benefits from the increasing demand for Wi-Fi and Bluetooth-enabled devices that provide real-time data. Experts predict a 30 percent growth in the microinverter segment by 2027.

At DRBO Greenenergy, we pursue a clear goal: to drive the decentralized energy transition together with our customers. We already supply numerous hardware stores, specialized dealers, and installation companies with high-quality solar and energy storage solutions, including models such as the AP Systems EZ1 for balcony power storage.

Technical Specifications of the AP Systems EZ1

The AP Systems EZ1 impresses with two independent inputs for PV modules. Maximum output power is 799 to 960 VA, depending on the EZ1-M or EZ1-H model. The input current is up to 20 A per channel, with a voltage range of 16 to 60 volts.

IP67 protection ensures weather resistance, and efficiency reaches a peak of 97.3 percent. An integrated relay provides NA protection, as confirmed in tests. The operating temperature ranges from minus 40 to plus 65 degrees Celsius.

Core Technology Analysis

Two MPPT trackers optimize each module string separately. High-frequency transformers ensure galvanic isolation and safety. The AP EasyPower App enables real-time monitoring and throttling at the touch of a button.

Night Power Consumption is only 20 mW. Natural convection cools without a fan. Firmware updates improve compatibility with bidirectional systems.

Real Use Cases with ROI

A tenant in Berlin installed two 420 Wp modules with EZ1-M. Annual yield: 850 kWh, amortization in 4 years at 0.30 Euro/kWh. Feedback: "Easy to install, app shows surplus live."

A single-family house user combined EZ1 with storage. ROI: 25 percent due to 800-watt release from 2025. Another case with an East-West setup yielded 15 percent more income than string inverters.

Buying Guide for AP Systems EZ1

Choose EZ1-M for standard balconies up to 800 Wp. Check VDE-AR-N 4105 compliance for Germany. Combine with full-black modules for aesthetic systems.

Look for original Stäubli MC4 connectors. Budget: 250-350 Euros per unit. Test app connectivity before purchase.

Future Trends and Forecasts

By 2027, balcony power plants will reach a total output of 2 GW. AP Systems plans an EZ1 successor with 1,000 VA and Matter integration. Bidirectional charging modes will become standard for electric cars.

AI-supported Energy Management optimizes surplus utilization. Forecast: 40 percent more installations due to subsidies.
