[Features]

1. „System Efficiency“

The key to the highest possible output is “Maximum Power Point Tracking” (MPPT) on a modular level.

In string-inverter based systems, MPP-Tracking is carried out for the entire array, often leaving modules working below their highest possible operating point.

In micro-inverter systems, MPP-Tracking is performed on a modular level, by varying the electrical operating point of the module’s cells according to their IV-Curve (Current-Voltage-Curve) to produce the highest possible power for that module. However, the MPP-Tracking can only work as efficient as their tracking range permits.

2. „Module Compatibility“

The Micro-Inverters are compatible with 48-, 54-, 60-, 72-, 80- and 96-cell modules due to their extra-wide MPP-Tracking range. The product variety with an input power of 250 watts up to 500 watts and an input voltage of 45 volts up to 90 volts offers more choices for increasing panel variety.

3. „MSD“

The Mains Monitoring Switching Device (MSD) according to VDE-AR-N 4105 is already integrated in the Micro-Inverters. This ensures that each inverter definitely separates itself from the power source during a power outage or network disconnection. MSD also prevents island formation and feeding back into the grid, which could possibly lead to dangerous consequences. In contrast to other micro-inverters, besides a protection, the Micro-Inverter does not need further monitoring or shut down devices. This simplifies every installation and reduces installation time and costs.

[Advantage]

1. „Avoidance of high energy losses“

The Micro-Inverter can increase the energy harvested, by eliminating sources causing high energy losses. In case of a shadow, snow, dirt, leaves, or other obstructions on a PV-module in a system using central or string inverters, the energy harvest of the entire string drops dramatically.

Due to the individual MPP-Tracking in micro-inverter-based PV systems, a shadow on one module does not affect others and therefore has only a minimal effect on the energy yield of the systems.

2.“Carefree Retrofitting“

With little effort, each system can be transformed and expanded with additional modules depending on needs and available capital.

Independently of whether the existing system consists of micro-inverters or is intended to expand a string system with new modules: with micro-inverters, you have all the freedom to upgrade your system at any time.
