Unique selling points of Fronius inverters in comparison to competitors

1. Dynamic Peak Manager

Fronius Dynamic peak manager

Fronius inverters are equipped with a Dynamic Peak Manager feature that enables them to manage temporary overload situations, such as sudden spikes in solar energy production. 

It is a shade management solution that is integrated into the Fronius inverter, designed to maximize the yield of a photovoltaic system even when there is partial shading

This shade-tolerant algorithm detects any shade and optimizes the yield at the string level, resulting in maximum yields despite shading.

By scanning the entire voltage output curve, the Dynamic Peak Manager always finds the most efficient operating point of the photovoltaic system, resulting in higher yields despite shading.

This helps to prevent system shutdowns and ensure that the system operates at peak efficiency.

Fronius conducted a study that showed a 7% higher yield on a 3.3 kWp photovoltaic system with partial shading when using the Dynamic Peak Manager compared to systems without shade management. 

2. Advanced Monitoring

Fronius inverters offer advanced monitoring features that enable real-time performance monitoring. With the Fronius Solar.web platform, users can access comprehensive data on energy production and system performance, enabling them to detect and address potential issues before they become significant problems.

Solar.web can be accessed from a smartphone or computer and offers a range of functions, including extensive analysis functions, automatic notifications, remote updates, and simulations.

With Solar.web, users can access important system data, such as energy production, consumption, and feed-in data, as well as performance ratios and environmental impact statistics

The remote update feature allows users to update their inverter software from a distance, ensuring that the system is always up-to-date with the latest features and performance improvements.

3. Advanced Grid Management

Fronius advanced grid management

Fronius inverters are equipped with advanced grid management (AGM) features that enable them to respond to changes in the grid voltage and frequency in real-time. This helps prevent system shutdowns and ensures that the system operates at optimal efficiency.

One of the key features of AGM is the ability to limit the power output of a photovoltaic system to ensure that it does not exceed the maximum allowable limit on the grid. This is important in areas where there is limited grid capacity, as it can help prevent overloading and reduce the need for costly grid upgrades.

In addition, AGM supports the integration of energy storage systems, which can be used to store excess solar energy generated during periods of low demand and release it during periods of high demand.

4. Wide Input Voltage Range

Fronius inverters have a broad input voltage range, enabling them to function with various solar panel configurations. This makes Fronius inverters a versatile choice for a wide variety of solar energy systems. 

Additionally, Fronius inverters are designed to operate efficiently even in low light conditions, which further enhances their versatility and performance.
