d. Some routers have 2 WiFi signals, one is 2.4GHz, the other is 5GHz. Most homes
use the 5GHz WiFi as their default WiFi but the charger can only connect to the 2.4GHz
WiFi. So if the charger can connect to your mobile phone hotspot, but cannot connect
to the home WiFi please check the router to see if you are using the 5GHz WiFi. Use the
2.4GHz WiFi for charger connection.
e. Check if the charger is still connected to the computer. Please unplug it from
computer otherwise the charger won’t connect to the back-oce server.
f. Check if server address is correct in the“Server URL” eld. The correct setting is :
ws://ess-charge.atesspower.com:80/ocpp/ws
7.4 Cannot access parameter setting page
a. Check if you have connected the charger to your computer,
b. Check if you have changed the computer’s IP to 192.168.1.x (x can be any value
between 1 and 255 except 5).
To set a static IP on your Windows computer:
(1). Click Start Menu>Control Panel>Network and Sharing Center. (For Windows 8 and
higher, search for and open Control Panel and select Network and Internet).
(2). Click Change adapter settings.

Load Management
7KW
Dynamic Load Management
For dynamic load management to work the CT clamp must be installed correctly and the
following setting must be set:
- Enable Power Allocation - Enabled
- External current sampling method - CT2000
- External monitored max input power (kw) - main fuse size
External monitored max input power is measured in kw and must be set to the main fuse
size so that if the load on the property was to reach the limit set the charger would reduce
it’s output accordingly to not exceed the property main fuse.
60A = 13kw
80A = 18kw
100A = 23kw
Static Load Management
For installations where dynamic load management is not possible you can hard limit the
charger using setting ‘charger maximum output current (A)’ - As default this will be 32A
(7.3kw) however can be downrated to as low as 6A (1.76kw) if required and anything
inbetween.
