This product range consists of masters and slaves. Like the slaves, the master contains an inverter, but it also offers additional functions: a four-line display, a data logger for storing the yield values, country-specific grid monitoring on the AC output side and the possibility of using an optional interface card.
Flexible system planning
Each inverter (master or slave) in the product series has two inputs, each with its own MPP tracker. One module string can be connected to each input. Depending on the requirements, the inputs can also be connected in parallel.
The advantage of this kind of system is its lower susceptibility to adverse influences such as partial shading, malfunctions or the failure of a string. By using several decentralised master/slave combinations, the costs of DC cabling can be reduced and electrical losses can be minimised.
The StecaGrid 2000+ inverter is equipped with a high-frequency transformer and is therefore galvanically isolated. This enables the unrestricted use of thin-film modules. Yet efficiency levels of up to 95% are still achieved.
The most diverse operating conditions
StecaGrid inverters offer constant performance over a wide ambient temperature range. This is supported by maintenance-free and natural convection via the generously dimensioned cooling fins. Since there is no fan, the inverter operation is virtually silent. Thanks to their high protection class, the StecaGrid inverters are also suitable for outdoor use.
The StecaGrid 2000+ and StecaGrid 2010+ (masters and slaves) can be combined with each other.
The StecaGrid 2000+ and 2010+ have a 5-year guarantee. The guarantee period can optionally be extended to 10 years.
