VI.Introduction of power management
and off-peak charging
6.1 Power management
The working principle of power management is as below,
Assume the max current can be supplied to the property is 40A, then the max power
is 40Ax230V = 9.2kW. So you can set the max power import to 9.2kW.
If CT is used to detect power import, then select CT as the power sampling device in
the parameter setting page. The charger will adjust charging power according to the
real-time power import and max power import.
When real-time import exceeds 90% of the preset max import value, the charger will
decrease charging power at a rate of 2A/sec until the real-time value drops between
80%-90% of the max value.
.
When real-time import drops below 80% of the max value, the charger will increase
charging power at 2A/sec until the real-time import falls between 80%-90% of the
max import value
Block diagram of power management

① Connect computer to the charger and enter the parameter setting page.
②
③Connect the CT wires or meter wires properly.
Set the max allowable power import and select power-sampling device. If meter is
used for power sampling, sampling interval also needs to be set.
6.2 Off-peak charging
① Connect computer to the charger and enter the parameter setting page.
② Set the allow charging time according to the local off-peak time period. Charging
is only allowed in this period unless the forced On/Off button is pressed. In peak time
period, plug the car to the charger, charging will wait until the off-peak time arrives.
VII.Home WiFi connection
If the ATESS EV charger you bought is WiFi version, then you can connect it to the
home WiFi and then monitor and control the charging on the Project EV APP.
There are 2 ways to set up the home WiFi connection, do it using a laptop connected
to the charger by LAN cable, or set up the connection directly on the APP.
In this instruction, we will show how to do it using the APP. Procedure is as below,
1. Open the “Project EV” APP, register an account and login with this account;
2. After login, click the “Add device” to add your EV charger to your account;

3. Enter the charger’s serial number, which can be found on the left hand side of the
charger, and click “Yes”;
4. Click the WiFi icon on the top right corner of the APP to connect your mobile to
the hotspot of the EV charger;
5. Turn on the breaker of the EV charger to power it up, then click “Go to the WLAN
page to set up” to connect the mobile phone to the hotspot generated by the
charger. The name of the hotspot is the charger’s serial number, the password is
12345678.

Please note: Every time when the charger is powered up, it will emit WiFi for 90sec,
you can connect the APP to this hotspot and set up charger parameters and home
WiFi connection during the 90sec. After 90sec, the charger will try to connect to the
home WiFi with the SSID and password information just filled in, the attempt will last
60sec. If the charger fails to connect to the home WiFi within the 60sec, it will emit
WiFi for another 90sec again for you to redo the setup.
6. When the charger’s hotspot is connected, your mobile might prompt you that this
is an non-Internet-accessible WiFi, Please select to connect it anyway. Then press the
arrow icon on the top left corner of the screen;
7. Click the “Next” button. Please check and make sure the mobile is connected to
the hotspot of the charger;
8. The APP will then obtain the charger’s parameters and enter the setting page;

9. Enter the name and the password of the home WiFi;
1 0 . S c r o l l d o w n t o s e t t h e s e r v e r a d d r e s s , w h i c h s h o u l d b e
“ws://charge.growatt.com:80/ocpp/ws” or “ws://47.254.157.66:80/ocpp/ws”.
Then click “Yes”;
11. Then click the arrow icon to back to the home screen, the charger will restart
when you exit the setting;
12. Wait for around 3 min, the charger will be online and ready for use.

VIII.Change server URL
The server URL is the address of the back-office server to which the charger will
connect to, it will be preset in factory before shipped out. In very few occasions, you
m i gh t f i n d t h a t t h e s e rv e r U R L i s i n c o r r e c t ( t he c o rr e ct s e t t i n g i s
“ws://charge.growatt.com:80/ocpp/ws”). If this happens, you’ll need to change it
using a laptop. The procedure is as below,
1. Open the front cover of the charger, set the all 4 bits of the DIP switch to ON
position(you need to first remove the film on the DIP switch using a tweezers);
2. Power up the charger, connect it to a laptop whose IP is in the same network
segment with the charger(should be192.168.1.x, while x is any value between 1 and
255 except 5). Then open the web browser to access the parameter setting page of
the charger;
3 . C ha ng e t he se rv er U R L t o t h e c or re ct se tt in g, w hi ch s h ou ld b e
“ws://charge.growatt.com:80/ocpp/ws”;

5. After the charger is restarted, enter the parameter setting page again to check if
you have changed it successfully. After that, please set the 4 bits of the DIP switch
back to OFF position.
IX.How to use power modulation
I. How does intelligent power adjustment work?
Intelligent power adjustment needs a power-sampling device on the incoming mains
supply cables, which could be a power meter or a current transducer and normally
located in the meter box.
Charger will adjust the charging power according to the pre-set power limit and the
real-time power consumption to ensure the total power import not exceed the
supplying capacity and not trip the main breaker.
Block diagram of power adjustment
II. Intelligent power adjustment setting
1.Connect the charger to a computer whose IP address should be set within the
192.168.1.x segment（x can be an y value be t w e en 1 an d 25 5 exce p t 5） ,
Enter the charger’s IP address of “http://192.168.1.5:8080” in the web browser and click
“Enter” to get into the parametersetting page of the charger.
