into 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 in abnormal operation conditions. At the same time, Control Board
can trigger the relay so as to protect the internal components.
Function module
A. Energy management unit
This control can be used to switch the inverter on/off through an external
(remote) control.
B. Feeding reactive power into the grid
The inverter is able to produce reactive power and can therefore 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 dedicated RS485 serial
interface.
C. Limiting the active power fed into the grid
The inverter, if enabled can limit the amount of active power fed into the grid by
the inverter to the desired value (Expressed as a percentage).
D. Self power reduction when grid is over frequency
When the grid frequency is higher than the limited value, inverter will reduce
output power which is necessary for the grid stability.
E. Data transmission
The inverter or a group of inverters may be monitored remotely through an
advanced communication system based on RS-485 serial interface, or remotely
via the WIFI/GPRS.
F. Software update
Support usb flash drive local upgrade software and WIFI/GPRS remote upgrade
