2.Street lamp Function
When the load is set to Dusk to Dawn or Evening mode, the voltage and the
Day/Night delay t can be set b IoT, RS485 or bluetooth APP, and the load can be turned on or off by
the test function during the day charging process.
2.1
The controller recognizes day and night based on the solar array open circuit voltage.
This day/night threshold
voltage can be modified according to local light conditions and the solar array
used. Max - EU defaults to 5.0/10.0V.
Day/Night threshold setting range: 3.0~10/6.0~20/9.0~30.0/12~40V(Default: 8/16/24/32V)
2.2 Day/Night delay time
In the evening, when the solar array open circuit voltage reaches the setting day/night detect voltage , you
can adjust the day/night delay time to make the load turn on a little bit later.
Day / Night delay time setting range: 0~30min(Default
:
0min)
2.3 Test Function
When the controller is working in Dusk to Dawn or Evening mode, press the MENU key for 3 s to turn on
the load. Press the MENU key again or the load turns off automatically after 1 minute.

1.If the controller turns off the load due to low voltage protection 、 overcurrent
protection 、 short-circuit protection or over temperature protection, the load will turn on
automatically when the controller recovers from protection state.
2.Please note: Pushing the MENU button can still activate the function of the key, even
during of the above four kinds protection states.

Check if other sources overcharge the battery.
If not, controller is damaged.

6.4 USB interface(Max-EU)
Max-EU series have two USB interfaces, maximum output of single USB is 5V 1.5A, maximum output of two
USB is 5V 2A, for charging mobile phones and other smart devices.
The USB stops output only when the controller is in low voltage protection.
