Fronius Symo GEN24 4.0 Plus

The hybrid inverter Fronius Symo GEN24 4.0 Plus in the three-phase version serves as the perfect heart for individual PV installations. With the PV Point feature, the Fronius GEN24 Plus offers built-in basic backup power and the ability to provide full backup power on a larger scale by connecting a battery.

Upon battery connection, the hybrid inverter Fronius GEN24 Plus enables achieving energy self-sufficiency in electricity, heating, cooling, and e-mobility.

Key features of the Fronius Symo GEN24 4.0 Plus inverter:

INTEGRATED DATA COMMUNICATION - The inverter offers a comprehensive data communication package, enabling full integration with Datalogging, WLAN, Ethernet, energy management, and network server. The inverter can be connected to the internet via a network cable or wirelessly through WLAN, ensuring efficient monitoring of the photovoltaic installation. Additionally, interfaces such as Modbus TCP, Modbus RTU SunSpec, or Fronius Solar API (JSON) allow easy connection of components from other companies. Furthermore, through the Fronius Solar.web online portal, open interfaces are available for additional flexibility.

DYNAMIC PEAK MANAGER - The Dynamic Peak Manager is a modern MPPT algorithm that dynamically adjusts to find the optimal operating point. It has the ability to find the Global Maximum Power Point (GMPP), even under partial shading.

MULTI FLOW TECHNOLOGY - The Multi Flow technology allows the inverter to simultaneously process different DC and AC energy flows. It can supply energy from modules and the battery simultaneously to the household and transmit energy from modules to the battery and home network. Additionally, the battery can be charged by both DC and AC circuits (e.g., from existing photovoltaic installations or other energy sources). This enables efficient cooperation with the AC network and regulation of energy flows, ensuring high self-powering from own energy.

SUPERFLEX DESIGN - Fronius SuperFlex Design is an innovative combination of technical features that greatly facilitates the design of photovoltaic installations. Key elements of SuperFlex Design include two MPP trackers, high system voltage, and a wide range of DC input voltages. Each DC input and MPP tracker can accept the full rated power of the inverter, regardless of roof orientation, module shading, or diversity of panels used. This flexibility allows the Fronius SuperFlex Design inverter to meet the requirements of any project using a single inverter model.

PV POINT - The integrated basic backup power function, powered socket in emergency situations, allows for the use of essential devices even during power outages.

ACTIVE COOLING - Active cooling technology, using one or multiple fans, not only eliminates potential overheating areas but also regulates airflow inside the inverter, maintaining a low temperature of the power electronic system. This process enhances device durability, optimizes performance, and reduces costs. Active Cooling is a standard technology in all Fronius products.
