This function allows the inverter able to control energy exported to the grid.
There are user value and factory value. The factory value is default which can not be charged
by user. The user value setting by installer must be less than the factory value.

6.Set EPS system(For E Version only)
X3-Retro Fit inverter with E Version can work on the EPS mode.
EPS parameters can be set as below.
- “Mute”means you can set the warning of system which has entered EPS mode.
- ”No”means there will be a buzzing and it is the default value.
- ”Yes”means you choose to shut down the warning function.
Besides ,if the buzzing is sharp, it means EPS output is over loads.“
Frequency “here can be set 50Hz or 60Hz please based on correlative loads.
1) Insert L/N wires and the 485cable
into the meter.

Battery will stop discharing to keep higher capacity when the
grid is on. Only when the gird is off and PV energy is not
enough, battery will start to discharge to keep the emergency
load working normally.
This work mode applies to the area where suffering from
blackout regularly.
The priority of inverter output power is:
supplying the load feeding to the grid charging the
battery.
This work mode applies to the area with high feed-in tariff.

The external generator generated power will be used to supply
the local loads firstly, then to charge the battery. The redundant
power will export to the public grid.
When there is no external generator supplied, battery will
discharge for local loads firstly, and grid will supply power when
the battery capacity is not enough.
In this work mode the charging and discharging time can be set
flexibly, and it also allows to select whether charge from the grid
or not.

Firmware Upgrading
Please ensure the inverter is steadily powered on. Inverter must keep the battery on through whole procedure of upgrading. Please prepare a PC and
an U-disk.
Preparation
Warning!
Make sure the battery voltage is more than 180V , otherwise it may result in serious failing during upgrading.
1) Please contact our service support to get the update les, and extract itintoyourU-disk as following: 
2) Press the “Enter” key for 5 seconds to enter Off Mode. Then unscrew the waterproof lid and insert U-disk into the “upgrade” port at the
bottom of the inverter.
“update\ARM\618.00098.00_Hybrid_X3G3_Manager_VX.XX_XX-XX.usb”;
“update\DSP\618.00096.00_Hybrid_G3X3_Master_VX.XX_XX-XX.hex”;
3) The LCD will be shown as the picture. Then press up and down to select the one that you want to upgrade and press “OK” to confirm to
upgrade.
