-In order to upgrade the firmware smoothly, if the DSP and ARM firmware needs to be upgraded, please note that ARM firmware must be upgraded
first, then DSP firmware!
-Make sure this directory is completely consistent with the above table, do not modify the firmware file name, Otherwise, the inverter may not work!
-For this inverter, ensure that the PV input voltage is greater than100V (upgrade on sunny days). Please ensure that the battery SOC is greater than 20%
or the battery input voltage is greater than 90V. Otherwise, it may cause serious failure during the upgrade process!
-If the ARM firmware upgrade fails or stops, please do not unplug the U disk and power off the inverter and restart it. Then repeat the upgrade steps.
1) Please check the inverter version and prepare a U disk (USB 2.0/3.0) and personal computer before upgrading.
2) Please contact our service support to obtain the firmware, and store the firmware in the U disk according to the
following path.

1) To connect the Communication line of the CT line, the lines need to be
made on both sides, connecting the RJ45 terminal on one side and the
Communication line Adapter on the other.
2) One side of the finished cable, Communication line adapter is inserted
into the inverter, and one side of the RJ45 terminal is inserted into the
CT connection.
The self-use mode is suitable for areas with low feed-in subsidies and high electricity prices.
① When the power of PV is sufficient
Active Charging or Discharge time period: PV will power the loads rstly, and surplus power will charge to the battery.
If the battery is fully charged, then sell the surplus power to the grid; ( The inverter will limit the output if Feed-in limit
or zero feed-in is needed.) (PV＞Load, PV →Load→Battery → Grid)
② When the power of PV is insufficient
Active Charging time period: PV will power the loads rstly, the remaining power will be taken from the grid, the
batter y will not discharge at this time.(PV＞Load, PV + Grid → Load)
Active Discharge time period: PV+BAT will power the loads together. If the power is still not enough, the remaining
power will be taken from the grid. (PV＜Load, PV + Battery + Grid → Load)
③ Without PV power
Active Charging time period: The grid supplies the loads and also can charge the battery.(PV=0, Grid →Load + Battery)
Active Discharge time period: The battery will power the home loads rstly. If the battery power is not enough, the
remaining power will be taken from the grid. The inverter will enter into the standby state. (PV=0, Battery+Grid→Load)
Batter y min SOC can be set:10%-100%; Charge battery to min SOC can be set:10%-100%.
The Feed-in priority mode is suitable for areas with high feed-in subsidies, but has feed-in power limitation.
①When the power of PV is sufficient
Active Charging time period: PV powers the load rst, then charges the battery to set capacity, then sell electricity for
the grid, and continues to charge the battery with the remaining power. (PV＞Load, PV→Load→Battery→Grid→Battery)
Active Discharge time period: PV will power the loads rstly, and surplus power will feed-in to the grid.
(PV＜Load, PV → Load → Grid )
②When the power of PV is insufficient
Active Charging time period:PV will power the loads rst, the remaining power will be taken from the grid. The battery
will not discharge.(PV＞Load, PV + Grid → Load)
Discharge time period: PV+BAT will power the loads together. If the power is still not enough, the remaining power will
be taken from the grid. (PV＜Load, PV + Battery + Grid → Load)
③Without PV power
Active Charging time period: The grid will power the home loads and also charge the battery.
(PV=0, Grid → Load + Battery)
Active Discharge time period: The battery will power the home loads rst. If the battery power is not enough, the
remaining power will be taken from the grid. The inverter will enter into the standby state. (PV=0 , Battery+Grid → Load)
Batter y min SOC can be set:10%-100% ; Charge battery to min SOC can be set:10%-100%.
The back-up mode is suitable for areas with frequent power outages. Same working logic with “Self-use” mode. This
mode will maintain the battery capacity at a relatively high level. (Users' setting) to ensure that the emergency loads
can be used when the grid is off. Customers no need to worry about the battery capacity.
Batter y min SOC can be set: 30%-100%; Charge battery to min SOC can be set: 30%-100%.
The EPS(Off-grid) mode is used when the power grid is off. System will provides emergency power through PV and
batteries to supply power to the household loads. (Batter y is necessary)
①When the power of PV is sufficent
PV will power the loads rst, and surplus power will charge to the battery. (PV＞Load, PV → Load → Battery)
②When the power of PV is insufficient
The remaining power will be taken from the battery. (PV＜Load, PV → Load)
③Without PV power
The battery will power the emergency loads until the battery reached the min SOC, then the inverter will enter into the
idle mode. (PV=0, Battery → Load)
EPS(Off-grid) SOC-min condition is adjustable within the range of 10%-25%.

Note!
The BMS port on the inverter is the communication port for connecting the
battery. The communication port on the lithium battery must be
consistent with the definition of pins 4, 5, 7, and 8 above;
Note:
For AS4777 DRM function, currently only PIN6 (DRM0) and PIN1
(DRM1/5) are functional, other PIN functions are under development.
Note!
Customers can communicate or control the inverter and external
devices through the COM interface. Professional users can use pins
4 and 5 to realize data acquisition and external control functions.
The communication protocol is Modbus RTU. For details, please
contact us. If the user wants to use the inverter dry contact to
control external equipment (such as a heat pump), it can be used
with our Adapter Box. For details, please refer to the Quick
Installation Manual of the Adapter Box.
