FRONIUS CL
The Fronius CL combines high-yield power electronics with the unique, modular system design of up to 15 identical power stages. Maximum yield and outstanding reliability are the advantages of this sophisticated system.
Features
Simple planning, easy installation:
The Fronius CL was designed with practicality in mind. It can be used for many different assignments due to its planning flexibility. It is also easy to set up due to numerous design details that make installation and connection as simple as possible.
Wide input voltage range:
Different module configurations are possible: The wide input voltage range ensures high flexibility for system configuration.
Integrated grounding option:
The Fronius CL is well-equipped should modules have to be grounded whether positive or negative. Simply change two wires and a software paramater to change from negative to positive grounding.
Optional exhaust air guide:
The Fronius CL is set up in a closed area, the exhaust air can be channeled out of the space using a connected pipe to prevent extreme heating of the ambient air. An integrated relay contact can also be used to control an external fan that draws the air to the outside.
Low installation height:
The Fronius CL can also fit into shallow spaces due to its low 72 inch height (with base). This compact design is achieved by its three-row arrangement of power modules in the inverter.
Low installation weight:
The power racks can simply be removed for installation. This reduces the weight of the Fronius CL and makes the housing easier to move. The racks can then be re-inserted and the inverter can begin operation immediately.
Generous connection area:
Sufficient space is available for connections and cabling with large cable cross sections. This makes installation simpler and much easier.
Technology
FRONIUS MIX TECHNOLOGY
The clever combination of multiple power stages means Fronius inverters always achieve maximum yield, even with partial-loads. This is due to the unique Fronius Master Inverter X-Change system (MIX), a development of the classic master/slave principle. How it works: All power stages are equal. The “master” is allocated alternately, depending on the operating hours. The result is that loads are applied evenly to individual power stages decreasing operating time on any one power stage.
Maximum efficiency under partial load
With MIX technology, get the maximum power harvest out of partial load ranges, e.g. on cloudy days, through a clever combination of multiple power stages in each inverter. The power stages in Fronius inverters divide up the work depending on operating hours and only operate as many power stages as required to efficiently process available power from the PV array.
Unrivalled stability
The redundant design means that even if one power stage fails the inverter continues to operate, ensuring yields are achieved. In the unlikely event a power stage fails the others will continue to operate.
Longer service life
Depending on the operation hours of each power stage, our inverters decide which power stages run under partial load conditions. This ensures that the work load is distributed equally between the power stages. The result is reduced operating time of individual power stages which increases the lifespan of the inverter.
AUTOMATIC HF TRANSFORMER SWITCHING
Fronius transformer inverters use a high-frequency (HF) transformer. The automatic transformer switching function produces three efficiency peaks. The result: A constant level of efficiency across the entire input voltage range, resulting in higher yields. Other key advantages of HF transformer technology are a compact, lightweight design, and safety as a result of the galvanic isolation.
FRONIUS MODULE MANAGER
The Fronius Module Manager always locates the maximum power point (MPP), even in the case of more demanding thin-film modules. The Fronius Module Manager achieves an outstanding MPP adaptation efficiency of >99.9 % in total.
UNIQUE PC BOARD REPLACEMENT PROGRAM
The foundation of our unique on-site PC board replacement program is laid as we develop our inverters, as PC boards can only be replaced if the device has been designed accordingly. This enables our Authorized Service Provider to offer the fastest inverter servicing on the market.
