2.3 Circuit Diagram
The MPPT is utilized for DC input to ensure the maximum power from the PV array at
different PV input conditions. The inversion circuit converts the DC power into AC power
and feeds the AC power into the utility grid through the AC terminal. The protection
circuit is equipped to ensure the safe operation of the device and personal safety.
The following Figure shows the main circuit of the inverter.

2.4 Function Description
The inverter is equipped with the following functions:
CCoonnvveerrssiioonn ffuunnccttiioonn
The inverter converts the DC current into grid-compatible AC power and provide it to
local loads or export it into the grid.
DDaattaa ssttoorraaggee
The inverter records running information, error records, etc.
PPaarraammeetteerr ccoonnffiigguurraattiioonn
The inverter provides various settable parameters. Users can set parameters via the
App to meet the requirements.
CCoommmmuunniiccaattiioonn iinntteerrffaaccee
The inverter is designed with standard RS485 communication interfaces.
The standard RS485 communication interfaces are used to establish communication
connection with monitoring devices and upload monitoring data by using
communication cables.
After communication connection is established, users can view inverter information or
set inverter parameters in a certain remote online portal.
PPrrootteeccttiioonn FFuunnccttiioonn
The protective functions are integrated in the inverter, including anti-island protection,
LVRT/HVRT, DC reversed polarity protection, AC short circuit protection, leakage current
protection, DC overvoltage/overcurrent protection, etc.
PPIIDD rreeccoovveerryy ffuunnccttiioonn
The inverter injects compensatinge voltage to PV strings to recovery PV string
performance when no power is generated.
