The further developed StecaGrid Configurator offering even more flexibility in the planning of grid-feed photovoltaic systems is now available. Version 3.3 has additional selection possibilities allowing the development of even more individual concepts for the customer.
Among the new features is the inclusion of the new 70 percent rule: If this is clicked on the "Inverter page", the configurator searches for a design relationship where the output power is only 70 percent of the module power. The new configurator also takes reactive power into account. The values "1.00", "0.95" or "0.90" can be selected in the "Cos Phi" field. Based on this decision, the inverters capable of providing the required reactive power are now available for the design process. With this new data entry possibility, Steca also takes into account that the inverter may no longer be able to provide the rated maximum reactive power at the specified cos phi value.
On the "Inverter" page, the system planner can now also specify the maximum and minimum module temperatures to be used by the configurator. The default values of "-10 degrees" to "+70 degrees" can now be freely defined by the user. The StecaGrid Configurator 3.3 now allows subsequent connection of additional modules. The corresponding page allows subsequent modification of the number of modules to be used in the selected system configuration. The effects of this change on the system values and yields is clearly shown. These values are displayed in red if the input parameters are exceeded.
To provide even more professional system planning, the updated configurator integrates the new features into the proven convenient user interface. The company planning the project can store its customer data and a company logo that are then shown on the printouts. A total of 100 locations throughout Europe offer irradiation data to help predict annual energy yields.
In addition to the StecaGrid Configurator 3.3, Steca also offer another professional design program that can be downloaded from the website at www.steca.de. The updated Excel-based StecaGrid Configurator 2.8.1 also accounts for the reactive power specifications of the grid operator. This program provides a convincing performance due to its speed and ease of use. In conjunction with the StecaGrid Configurator 3.3, the update to this proven design program guarantees professional planning of a grid-feeding photovoltaic system.
