Fronius Primo GEN24 Plus

The hybrid all-rounder with individual back-up power

With need-based emergency power variants, which can operate with or without a battery, the Fronius Primo GEN24 Plus delivers the highest degree of supply reliability for the home sector.

The innovative PV Point provides for the first time a basic emergency power supply even for those customers who do not wish to purchase a battery straight away. For customers who already have a battery, the device offers a tried-and-tested full backup solution that can supply the entire household with emergency power. 

The Fronius GEN24 Plus devices are therefore the ideal solution for a whole range of customer requirements; whether the system is to have a battery from day one, a Fronius Ohmpilot is to use PV energy to heat the hot water, or the PV system is to be integrated into a home automation package. Fronius GEN24 Plus will always be the right choice – for new systems as well as the upgrade and expansion of existing solar systems.

Furthermore, the new devices make installation, commissioning and servicing incredibly easy and can be used in every type of system. Proven Fronius technologies, such as the SuperFlex Design, will also be found in the Primo and Symo GEN24 Plus – devices that offer ideal storage solutions for single-phase and large three-phase systems.

Integrated data communication

We are the first inverter manufacturer to offer a data communication package with fully integrated datalogging, WLAN, Ethernet, energy management, web server and a range of interfaces. The inverter is connected to the internet by network cable or WLAN - without additional cabling - and grants you the perfect overview of how the PV system is operating. Connection to third-party components is provided by means of interfaces such as Modbus TCP SunSpec, Modbus RTU SunSpec or Fronius Solar API (JSON). The open interfaces can also be operated in parallel to the Fronius Solar.web.

Dynamic Peak Manager

The Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts its behaviour when searching for the optimal operating point. Its special feature is that the Dynamic Peak Manager automatically checks the entire characteristic curve on a regular basis and finds the global Maximum Power Point (GMPP), even in partial shade.

Multi Flow Technology

Using Multi Flow Technology, different DC and AC energy flows are possible in parallel. On the one hand, this allows energy from the modules and from the battery to be made available for domestic use at the same time. However, it is also possible for the energy from the modules to be simultaneously fed into the battery and the in-house network. Furthermore, not only can the battery be charged from the DC side, but also from the AC side (for example from existing PV systems or other energy sources, such as a wind turbine). This means the inverter is also suitable for AC-coupled retrofitting. The inverter manages these energy flows in such a way that the highest possible degree of self-sufficiency is achieved.

SuperFlex Design

The Fronius SuperFlex Design is an ingenious combination of technical performance attributes that make designing your PV system not only extremely simple, but also incredibly flexible. The key performance factors of the SuperFlex Design are two MPP trackers, together with a high system voltage and wide DC input voltage range. Every DC input, and therefore every MPP tracker, is able to accommodate the entire nominal output of the inverter. Regardless of whether the inverter has to cope with different roof orientations, shading of one or two strings, or the use of residual modules: a Fronius inverter featuring integrated SuperFlex Design will satisfy every conceivable operational PV system planning scenario using just a single inverter model.

Back-up power

With need-based emergency power variants, which can operate with or without a battery, the inverter delivers the highest degree of supply reliability for the home sector: / Back-up power option possible with and without battery / Basic grid back-up (PV Point) integrated as standard / Full back-up option offers maximum independence

PV Point

The integrated basic grid back-up - a socket that is supplied with power during power outages - ensures that important loads can conitunue to operate should the power fail. The PV Point can be used with as well as without battery.
