Step 1. Prepare a Grid cable (three-core wire) and an Off-grid cable (two-core wire), and then find the European terminal and waterproof cover in
the accessory bag.
Step 2: The Gridand Off-grid cables go through the corresponding Grid and Off-grid ports of the waterproof cover. Remove the 12mm insulation
layer at the end of the wire. Insert the European-style terminals respectively, and make sure that the stripped ends are inserted into the
European-style terminal ,and finally use crimping pliers to press tightly.

-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 that this directory is completely consistent with the above table, do not modify the firmware file name,Otherwise, the inverter may not work!
-For X1-Hybrid G4, 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.
Upgrade preparation
1) Please check the inverter version and prepare a U disk (USB 2.0) and personal computer before upgrading.
2) Please contact our service support through [e-mail] to obtain the firmware, and store the firmware in the U disk according to the
following path.

Update:
For ARM file:“update \ARM\618.00361.00_Hybrid_X1G4_ARM_V1.01.0710.usb”;
For DSP file:“update\DSP\618.00360.00_Hybrid_X1G4_DSP_V1.01.0710.usb”;
Upgrade steps
Step 1. Please save the "Upgrade" firmware in your U disk first, and press the "Enter" button on the inverter screen for 5 seconds to enter the OFF
mode.

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
battery 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 batter y 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)
Battery 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 will power the loads rstly, and surplus power will feed-in to the grid. If the feed-in
power has been limited ,the surplus power can charge the battery. (PV＞Load ,PV → Load → 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 rstly, 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 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)
Battery 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.
Battery min SOC can be set:30%-100%.Backup mode SOC adjustment range :30%-100%;In Backup mode,
SOC-min under off-grid condition is 10%, which cannot be modied.
The 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. (Battery is necessray)
①When the power of PV is sufficent
PV will power the loads rstly, 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)
