SNAPINVERTER TECHNOLOGY
The new generation of SnapINverter inverters is characterized by a simple mounting system, which makes installation and maintenance easier than ever before. A special design feature of these devices is the separation of the connection and power parts. Each is installed separately. The extremely lightweight connection part, including all cables, is first mounted on the wall. Then the power part is mounted. The innovative rotation concept allows the user to install and service extremely conveniently. The inverter is simply hung in the wall bracket and then secured. In the event of service intervention, it is therefore not necessary to dismantle the entire inverter, but only its power part. All cabling remains intact.
INTEGRATED DATA COMMUNICATION
We are the first inverter manufacturer to offer a data communication package with fully integrated data logging, WLAN and Ethernet technologies , energy management, web server and many interfaces. This allows the inverter to be connected to the Internet via network cable or WLAN (without additional cables) and provides an optimal overview of the operation of the photovoltaic system. Interfaces such as Modbus TCP SunSpec, Modbus RTU ensure connection to third-party components SunSpec or Fronius Solar API (JSON). In addition, open interfaces can be used in parallel to access the Fronius Solar.web software.
SUPERFLEX DESIGN
Fronius SuperFlex Design technology offers a sophisticated combination of technical parameters that now allow you to set up your photovoltaic systems much more flexibly and easily. The most important performance factors of SuperFlex Design technology are: Two MPP trackers in combination with a high system voltage and a wide DC input voltage range. In addition to This means that each DC input, and therefore each MPP tracker, can receive the full rated power of the inverter at any time. With different roof orientations, shading can be used with one or two branches or with the remaining panels.DYNAMIC PEAK MANAGER
The Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts the behavior to find the optimal operating point. The special feature is that the Dynamic Peak Manager algorithm automatically periodically it checks the entire characteristic and therefore can find the global maximum power point (GMPP) even in partial shading.SMART GRID READY
Fronius inverters are ready for the Smart Grid technology of the future. The inverters are perfectly equipped for future requirements in the field of grid technology. The devices are equipped with a number of intelligent functions, so-called advanced grid functions. These are various control functions for the optimal supply of reactive and active power to the grid. The aim of these functions is to enable safe grid operation even with very high densities of photovoltaic cells. And also to prevent unwanted interruptions in the power supply due to exceeding the grid parameter limits and the associated loss of profit. With Fronius inverters, the yield of the photovoltaic system is therefore optimally secured. In addition, Fronius inverters can also be used to dynamically regulate the power supply to the grid taking into account self-consumption in the event of supply restrictions. Just connect the electricity meter and set the supply limit.ZERO FEEDING
Electricity grid operators in many countries are increasingly demanding the ability to limit the feed-in of photovoltaic energy to the grid as a condition for grid connection. With dynamic power limiting, Fronius offers a solution for optimally managing the feed-in of energy to the grid. Inverter first supplies household appliances. It then limits the power to the maximum power consumption permitted by the grid operator. With Fronius inverters, this function also makes zero-feed possible. No current is therefore fed into the grid and the grid operator's requirements can be met by simply setting it in the inverter's web interface.ACTIVE COOLING
Active cooling technology uses one or more fans to prevent local overheating and at the same time regulate the air circulation inside the inverter. This keeps the power supply temperature low. electronics, noo leads to a longer service life of the device, optimal yield and lower costs. At Fronius, active cooling is the technological standard for all devices.NOTE ON TECHNICAL DATA
