Hybrid inverter Fronius Primo GEN24 3.6 Plus

INVERTER FOR PRIVATE PV SYSTEMS WITH PV POINT OR FULL REDUCTION
Our single-phase hybrid inverter Fronius GEN24 Plus is the ideal core for private photovoltaic systems. The Fronius GEN24 Plus offers an integrated basic backup power supply with a photovoltaic point and even a full backup power solution with the option of connecting a battery storage system.

The Fronius GEN24 Plus hybrid inverter provides energy self-sufficiency for electricity, heating, cooling and electric vehicles using a battery system. This means that the Fronius GEN24 Plus with full backup has a backup power solution that can even power three-phase loads such as heat pumps. Moreover, Multi Flow technology allows the hybrid inverter to supply parallel energy flows to the system even in standby mode.

The main difference between the Fronius Primo 3 GEN24 and Fronius Primo 3 GEN24 Plus inverters is The Plus model has a backup power function. This means that in the event of a power outage, the inverter can provide power to all consumers connected to it, including three-phase ones, such as electric boilers or pumps.

In addition, the Fronius Primo 3 GEN24 Plus inverter supports the Smart Grid Ready function, which allows it to work in harmony with the electrical grid. This means that the inverter can take part in managing the grid load, for example by reducing its output during peak hours.

TECHNOLOGIES

INTEGRATED DATA COMMUNICATION
We are the first inverter manufacturer to offer a data communications package with fully integrated data logging, WLAN, Ethernet, energy management, web server and a range of interfaces. The inverter connects to the Internet via a network cable or WLAN - without additional cables - and gives you a perfect overview of the PV operation systems. Connection to third-party components is carried out via interfaces such as Modbus TCP SunSpec, Modbus RTU SunSpec or Fronius Solar API (JSON). The open interfaces can also be used in parallel with Fronius Solar.web.

DYNAMIC PEAK MANAGER
Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts its behavior to find the optimal operating point. Its special feature is that Dynamic Peak Manager automatically checks the entire characteristic curve on a regular basis and finds the global maximum power point (GMPP) even in the penumbra.

MULTI-THREADING TECHNOLOGY
Using Multi Flow technology, parallel flows of DC and AC energy are possible. On the one hand, this allows you to simultaneously use the energy of the modules and batteries for domestic use. However, it is also possible to simultaneously supply energy from the modules to the battery and the intra-house network. Moreover, the battery can be charged without only on the DC side, but also on the AC side (for example, from existing photovoltaic systems or other energy sources such as a wind turbine). This means that the inverter is also suitable for retrofitting with an AC connection. The inverter manages these energy flows in such a way that the greatest possible degree of self-sufficiency is achieved.

SUPERFLEX DESIGN
Fronius SuperFlex Design is an ingenious combination of technical features that make designing your photovoltaic system not only extremely simple, but also incredibly flexible. Key to the performance of the SuperFlex design are the two MPP trackers, as well as the high system voltage and wide DC input voltage range. Each DC input and therefore each MPP tracker is capable of delivering the inverter's full rated output power. Regardless of whether the inverter has to cope with different roof orientations, shading of one or two strings or the use of residual modules: the Fronius inverter with integrated SuperFlex design will satisfy every conceivable planning scenario for an operational PV system using only one inverter model.

FULL BACKUP
Thanks to the full backup option, the entire house, i.e. both single-phase and three-phase devices, can be supplied with electricity in the event of a power outage.

PV POINT
Built-in core backup—the outlet that receives power during a power outage—ensures that critical loads can continue operating in the event of a power failure.

ACTIVE COOLING
Active cooling technology is based on the use of one or more fans, which not only avoid overheating, but also regulate air circulation inside the inverter, thereby maintaining a low temperature of the power electronics. This has a positive effect for the service life of devices, optimizes product yield and reduces costs. At Fronius, active cooling comes as standard on all devices.
