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 the port (4th) on the controller.

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 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.

distance is within 150mm. (4) The VS-A series

is a positive ground controller. Any positive connection of solar

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

necessary.

5. Protections

 PV Short Circuit

When PV short circuit occurs, the controller will stop charging. Clear it to resume normal

operation.  PV Reverse Polarity Fully protection against PV reverse polarity, c

orrect the wire connection to resume

normal operation.  Battery Reverse Polarity

Fully protection against battery reverse polarity, c

orrect the wire connection to resume

normal operation.

Warning：Shock Hazard!

When the battery is reverse, the load will app

ear the equal

polarity voltage to battery.

 Battery Over Voltage

When the battery voltage reaches to the set point of Over Voltage

the controller will stop

charging the battery to protect the battery from being over

charged to break down.  Battery Over Discharge

When the battery voltage reaches to the set point of Low Voltage Disconnect

the controller will stop discharging the battery to protect the

battery from being ove

discharged.  Battery Overheating

The controller detect the battery temperature through the external temperature sensor. If

the battery temperature exceeds 65ºC, the controller will automatically start the

overheating protection to stop working and recover below 50 ºC.  Load Overload

Load will be switched off when 1.05 times rated current overload happens. Controller

ill automatically attempt to reconnect load for 5 times. If overload protection still exist

after controller’s 5 times attempts, user have to

reduce load appliance, then

SET button or repower the controller or wait for one night-

day cycle (night time>3

hours).  Load Short Circuit

Load will be switched off when load short circuit (≥

4 times rated current) happens.

Controller will automatically attempt to reconnect load for 5 times. If short circuit

protection still exist after controller’s 5 times attempts, user have to

circuit ,then press the SET button or disconnect and restart the

controller or wait for one

night-day cycle (night time>3 hours).  Damaged Remote Temperature Sensor

If the temperature sensor is short-

circuited or damaged, the controller will be charging or

discharging at the default temperature 25 to preven℃

t the battery damaged from

overcharging or over discharged.  Controller Overheating

If the temperature of the controller heat sinks exceeds 85

, the co℃

automatically start the overheating protection and recover below 75

 High Voltage Transients

PV is protected against small high voltage surge. In lightning prone areas, additional

external suppression is recommended.

8. Disclaimer

Damage from improper use or use in an

PV or load current, voltage or power exceeding the rated value of controller.

User disassembly or attempted repair the controller without permission.

The controller is damaged due to natural elements such as lighting.

The controller is damaged during transportation and shipment.

Any changes without prior notice!

Troubleshooting

Confirm that PV wire connections are correct and tight

1. Please check the voltage of battery. At least 9V voltage to activate the controller

2. Check the PV input voltage which should be higher than battery’s Check if the battery voltage is higher than OVD point (over voltage disconnect voltage), and disconnect the PV. When the battery voltage is restored to or above LVR point (low voltage reconnect voltage), the load will recover The controller will automatically turn the system off. But while the temperature decline to be below 50 ºC, the controller will resume.
