Photovoltaic (PV) Ancilliaries
StecaGrid 2000+
2,000 W up to several 10,000 W
The DualString product range consists of masters and slaves. Like the slaves, the master includes an inverter, but it also provides additional functions: a four-line display, a data logger for storing the yield values, country-specific grid monitoring of the alternating current output, and optional use of an interface card.
Flexible system design
The StecaGrid 2000+ uses the DualString concept. This means that every inverter (master or slave) has two inputs, with each input having its own MPP tracker. One module string can be connected to each input. If required, the inputs can also be connected in parallel.
The advantage of such a system is the low sensitivity to negative influences such as (e.g.) partial shadowing, functional faults, or the dropout of a string. The use of several decentralised master-slave combinations reduces the cost of DC cabling, and minimises electrical losses.
Galvanic isolation
DualString inverters from Steca are equipped with a high-frequency transformer, and are thus galvanically isolated. This enables unrestricted use of thin-film modules. Nevertheless, high efficiency of up to 95 % is achieved.
Diverse application situations
StecaGrid inverters offer constant high-power capability over a wide range of ambient temperatures. This is supported by maintenance-free, natural convection via the large-dimension cooling fins. Since no fans are used, the inverters work in virtual silence. Thanks to the high degree of protection, StecaGrid DualString inverters are also suitable for outdoor installation.
StecaGrid 2000+ D Master and StecaGrid 2000+ Master can be combined with StecaGrid 1900 Slave and StecaGrid 2010+ Slave.
Guarantee service
The StecaGrid 2000 and 2000+ come with a 5-year guarantee. The guarantee period can be optionally extended up to 10 years.

Fronius CL 36.0 48.0 & 60.0
High-yield power electronics
The Fronius CL was designed for continual high performance. The clever combination of automatic transformer switching, the precise Fronius Module Manager, the innovative ventilation concept and the advantages of the high frequency transformer technology make it one of the highest yield inverters of its class.
Automatic transformer switching
The Fronius CL provides constant, high efficiency over the entire input voltage range. This is because Fronius inverters have three efficiency peaks due to automatic transformer switching. In comparison: Devices without transformer switching only have one efficiency peak. The efficiency then decreases steadily with an increasing input voltage.
Exact MPP tracking
The Fronius Module Manager always finds the exact maximum power point (MPP). This is true even with the more demanding thin-layer modules. Overall, the Fronius Module Manager is able to achieve an outstanding MPP adaptation efficiency of 99.9%. This ensures that the maximum yield is obtained from every ray of light.
High-frequency transformer technology
High performance with low weight and a compact design: The use of proven high-frequency transformer technology produces excellent performance results. The Fronius CL uses galvanic isolation, which meets the strictest safety standards worldwide.
Intelligent cooling
An innovative ventilation design eliminates dust and moisture from getting into the power module area. The air required for cooling is drawn in by two fans on the front of the device and passed through a closed channel through the individual power racks. The PC boards never come into contact with the outside air. Inside the hermetically sealed power module, a smaller fan ensures uniform cooling. This sophisticated system increases the operational reliability and the service life of the inverter.

PV Monitoring
The GEO Solo PV
Using the standard GEO display layout (designed to simulate a car dashboard) the Solo PV comes with a colour, backlit screen. These similarities make the display very intuitive and easy for users to understand. It provides live generation information to the user giving a clear picture of how well their PV array is performing. This information can be shown as money earned via feed in tariffs (FITs), kilowatts generated or the amount of CO2 saved. The display also shows generation over the course of the day, yesterday and the last 7-days.
