2.2. Function Description
DC power generated by PV arrays is filtered through Input Board then enters Power
Board. Input Board also offer functions such as insulation impedance detection and
input DC voltage/ current detection. DC power is converted to AC power by Power
Board. AC power is filtered through Output Board then AC power is fed into the grid.
Output Board also offer functions such as grid voltage/ output current detection,
GFCI and output isolation relay. Control Board provides the auxiliary power, controls
the operation state of inverter, and shows the operation status by Display Board.
Display Board displays fault code when inverter is abnormal operation conditions. At
the same time, Control Board can trigger the replay to protect the internal
components.
Function Module
A. Energy management unit
Remote control to start/ shunt down inverter through an external control
B. Feeding reactive power into the grid
The inverter can produce reactive power thus to feed it into the grid through
the setting of the phase shift factor. Feed-in management can be controlled
directly by the grid company through a RS485 interface.

C. Limited the active power fed into grid
If enable the limited of active power function, inverter can limit the amount of
active power fed into the grid to the desired value (expressed as percentage)
D. Self-power reduction when grid is over frequency
If grid frequency is higher than the limited value, inverter will reduce the output
power to ensure the grid stability
E. Data transmission
Inverter or a group of inverters can be monitored remotely through an
advanced communication system based on RS485 interface or via Wi-Fi
F. Software update
USB interface for uploading the firmware, remotely uploading is available.
2.3. Electrical block diagram
E- 75~136KTL has 16-24 DC input strings. 8-12 MPPT trackers that converts the direct
current of PV array to grid-compliant, three phase current and feeds in into the utility
grid. Both DC and AC side has Surge Protection Device (SPD).
