ultiple load control modes
can be widely used on solar home system, traffic
signal, solar street light, solar garden
lamp, etc. The features are listed below:
3-Stage intelligent PWM charging：
Bulk, Boost/Equalize, Float
Support 3 charging options: Sealed, Gel, and Flooded
LCD display design, dynamically displaying device
’s operating data and working
condition

) 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-Aseries
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
w
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

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