Optional Accessory:
Name: Remote Temperature Sensor
Model : RTS300R47K3.81A
Acquisition of battery temperature for undertaking temperature compensation of
control parameters, the standard length of the cable is 3m (length can be
customized). The RTS300R47K3.81A connects to port 0 on the controller.
NOTE: Unplug the RTS, the temperature of the battery will be set to a
fixed value of 25°C.
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 powering on the controller, check the LCD. 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 the 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 has a large start
current to the battery rather than to the controller if the inverter or
other load is necessary.

Troubleshooting
| Faults | Possible reasons | Troubleshooting |
|---|---|---|
| The LCD is off during the daytime when sunshine falls on PV modules properly | ||
| PV array disconnection | Confirm that PV wire connections are correct and tight |
Wire connection is correct, LCD not
display| 1) Battery voltage is lower than 9V
2) PV voltage is less than battery voltage| 1) Please check the voltage of
the battery. At least 9V voltage to
activate the controller2) Check the PV input voltage which should be
higher than
battery’s
Interface blink| Battery over voltage| Check if the battery voltage is higher
than OVD point (over-voltage disconnect voltage), and disconnect the PV.
Interface blink| Battery over-discharged| When the battery voltage
is restored to or above the LVR point (low voltage reconnect voltage), the
load will recover
Interface blink| Battery Overheating| The controller will automatically turn
the system off. But while the temperature decline to be below 50 °C, the
controller will resume.
Interface blink| Overload or Short circuit| Please reduce the number of
electric equipment or check carefully the loads connection.
