Sofar 100KTLX-G4 User Manual

FunctionsFunctions
A. Digital inputs (DRMs)
Theinvertercanbeswitchedon/o󰘯orthegridpowercanbecontrolledviatheexter-
nal control.
B. Feeding of reactive power into the grid
The inverter is capable of generating reactive power and can also feed it into the
grid. The setting of the power factor (Cos Phi) can be controlled via the serial RS485
interface.
C. Limitation of the active power fed into the grid
Theinvertercanlimittheactivepowerfedintothegridtoaspeci󰘰cvalue(asaper-
centage of the rated output).
D. Output reduction at overfrequency within the grid
If the grid frequency is higher than the limit value, the inverter will reduce the output
power; this is required to ensure stability of the grid.
E. Data transfer
The inverter (or a group of inverters) can be monitored remotely via the RS485 com-
munication bus or via WiFi/GPRS.
F. Software update
The device supports local updates via USB stick and remote updates via WiFi/
GPRS.
G. PID recovery
ThePIDe󰘯ectofPVmodulescanberecoveredduringnight-timebyapplyinga
negative DC voltage to the PV Array.
H. AFCI (Arc Fault Circuit Interruptor)
TheinverterdetectsarcfaultsonthePVgeneratorsideandswitcheso󰘯toprotect
the system.
I. IV Curve Scanning
The IV curve for each MPPT can be measured on demand and used in the monitor-
ing portal to analyze potential issues in the PV array.
J. Integrated grid relais
The relais can be operated by a central grid protection device to disconnect the
inverter within 100 ms.
