SMA system technology offers comprehensive yield monitoring while meeting all the requirements of the grid operator regarding the provision of grid services. With the SMA Power Plant Controller, your PV power plant can play an active role in stabilizing the grid. Due to its highly flexible range of control features, downtimes are reduced and yields are maximized.
By offering quick and direct control, the SMA Power Plant Controller allows grid and PV plant operators to maintain target values for responding to requirements from the PV power plant and the grid.
With intelligent algorithms and fastest communication it is an efficient controller for the entire PV system. The SMA Power Plant Controller is the central control unit for all inverters in the PV field.
Thanks to its easy expandability for new communication protocols, standards for inidividual connections and a modular design, the SMA Power Plant Controller is well suited to meet the future requirements of PV power plants worldwide.
Optiprotect is an intelligent string monitoring feature that is installed centrally in the inverter. A self-learning algorithm is used to reliably detect and handle errors in the PV field. String failures are monitored and analyzed.
If insulation faults occur, Optiprotect will disconnect the defective substrings from electricity production via circuit breakers. This avoids having to shut down the entire PV array. Electricity production continues. Your PV power plant achieves maximum yields.
Cyrosh Ebrahimi, General Manager of PV Strom, on his experience with Optiprotect:
"All of simulated faults and those that actually occured were quickly detected and localised.
Optiprotect combines intelligent software and clever hardware, enabling us to selectively monitor the DC inputs. This allows us to individually check the DC inputs as well as isolate faults if they occur in the module array.
It provides us with a huge advantage, since the Sunny Central 500CP offers greater availability, because it does not need to be switched off. This eliminates the need for immediate servicing.
In addition, clever software actively uses a special algorithm that "gets to know" the PV array and can localise, report and if neccessary, manage performance deviations on each DC input after the learning process has been completed. The fact that intelligence capabilities are not required in the DC sub-distribution units and that they are centrally relocated in the inverters reduces costs."
