USB output ports provide the power supply of 5VDC/2.4A and have the short
circuit protection.
NOTE: Unplug the RTS, the temperature of battery will be set to a fixed
value 25ºC.
3. Wiring
(1) Connect components to the charge controller in the sequence as shown above and pay
much attention to the “+” and “
-
”. Please don’
t insert the fuse or turn on the breaker during
the installation. When disconnecting the system, the order will be reserved.
(2)After power on the controller, check the LCD on. Otherwise please refer to chapter
6.Always connect the battery first, in order to allow the controller to recognize the system
voltage.
(3)The battery fuse should be installed as close to battery as possible. The suggested
distance is within 150mm.
(4) The VS AU series is a positive ground controller. Any positive connection of solar, load
or battery can be earth grounded as required.
NOTE: Please connect the inverter or other load that it has the large start
current to the battery rather than to the controller, if the inverter or other
load is necessary.
