Fronius and Tesla have partnered on a global level to offer Powerwall in combination with the Fronius Symo Hybrid inverter as a seamless solution for residential PV systems. For new PV installations, homeowners can use the Fronius inverter to operate both the PV and Powerwall, which reduces the overall system cost. For homeowners that already have solar PV, the Fronius inverter can be added to the system (AC coupled) or replace the existing inverter (DC coupled), and the Fronius solution will function with any type of solar energy system. This makes the Fronius plus Tesla solution a highly flexible solution across the globe.
Fronius is a leading inverter manufacturer in the global market, with nearly 1 million inverters installed worldwide. Fronius is known for both innovation and high quality, with 1,008 active patents and 23 years of solar experience. Its products are exported through 22 international Fronius subsidiaries and sales partners/representatives in over 60 countries. The company is a multi-industry leader in the fields of energy storage, battery charging, and welding technology. Fronius and Tesla are pleased to expand a current successful relationship into the realm of energy storage.
The new SnapINverter generation of inverters features a simple, standardised mounting system, making installation and maintenance easier than ever. The special feature in the design of the device is that the connection area is separate from the power stage set compartment. They are installed separately. The remarkably light connection area and all its cabling is fitted to the wall first. The power stage set is installed afterwards. The innovative hinged system makes installation and servicing extremely user-friendly. The inverter is simply placed in the wall bracket and then secured. This means that it is not necessary to remove the entire inverter for servicing, just the power stage set. All the cabling remains in place.
We are the first inverter manufacturer to offer a data communication package with fully integrated data logging, 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.
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 in conjunction 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. A Fronius inverter with integrated SuperFlex Design will satisfy every conceivable operational PV system planning scenario using just a single inverter model, including different roof orientations, shading of one or two strings, or the use of residual modules.
The Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts its behaviour when searching for the optimal operating point. The 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.
Fronius inverters are ready for the Smart Grid of tomorrow. The inverters are optimally equipped to meet the technical requirements of grids in the future. A series of smart functions, known as Advanced Grid Features, are built into the devices. These include a number of control functions for optimum feed-in of reactive power and effective power. These functions are designed to enable stable grid operation even when the PV system density is very high and to prevent unwanted interruptions to feed-in and associated yield losses if grid parameters exceed the thresholds. Fronius inverters therefore help to guarantee the yield of a PV system. Furthermore, where feed-in limits are imposed, Fronius inverters can provide dynamic feed-in control with self-consumption taken into account. Just connect the meter and set the feed-in limit!
The storage solution from Fronius is a compact system which can be adapted to individual requirements thanks to its modular design. All the functions are built into the inverter so that it can be expanded into a comprehensive storage solution at any time. The device can be used simply as an inverter with emergency power function and no battery, or as the full version with a battery and emergency power function. The result: sun by day, sun by night and sun during power outages.
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.

The personal storage solution for 24 hours of sun.
The Fronius Symo Hybrid allows any surplus of a photovoltaic system to be stored in a battery. The result: maximum self-consumption of the available power as well as maximum energy independence.
Advanced Grid Features for a stable grid
The Advanced Grid Features (AGF) incorporate a range of functions that support reliable grid operation. They prevent grid faults and unexpected failures leading to yield losses. In line with new guidelines for energy fed into the grid, these features can be activated at any time.
