SOLAR TORRENT
Solar Charge Controller Series
The Solar Charge Controller offers by SolarTorrent.com are for use in solar photovoltaic systems,
which coordinate the working of solar panels, batteries, and loads. It adds protection functions,
so that the entire system can be used safely and efficiently.
WS-C series charge controllers are applicable to all types of photovoltaic panels and various
types of batteries, MCU (Micro-Processing Controller) has PMW (Pulse Modulation
Wide-frequency) 0~100% variable duty cycle process. According to the types and actual
charging situation of the battery, WS-C controller series can provide fast and best charging
voltage and electricity from the PV panel. C30 and C60 series are equipped with advanced
man-machine interactive function, so the user can adjust the charging voltage.

is no less than IOV (as per 12V batter\) or 20V (as per 24V battery),
If voltage or tlJe ballery is less than I ',I\' (or 20V), the button "-"
will stop working.
To reco\er thc default parameters, please keep preSSing the
bullon ",",1c'nu" for more than 5 sec'l:nds.
3. CONNECTION
As indicated in diagram: Connect "+" and "-" poles of
solar panel with the correct terminals l>I' the controller (the first and
second termil,ah from the left).
Connect ., +" and "-" po':, of battery with the correct
terminals on the cOlltroller (the third and fourth terminals Ii'om the
left ),
and

terminah un the cuntroller (the frlil, :lnd sixth terminals from the
left).
Attention'
First eOll'leet the solar controller v\ ith the battery,
Correctly connect the electrode; of solar panels. battery and
loads.
Chuuse the proper wire according to the current of the loads; it
is suggested lhat the diameter of \'/S-C2425 lllust bigger than 4

Installation: Plug the thermoscope into the "'Jeket (top)
of controller before running of controller, and th,:n connect
battery with the controller. The thermoseopc will normally
work aftcr one minute. (Operatc as indicated in the Fourth
Chapter; the environmental temperature of controller will be
showed on LCD).
Optional Accessory: Long-distancc thcrmoscopc
Such thermoscope is suitable to thc following
condition- the location of battery is far aW:lY from the
controller.
Installation: Plug the thermoscope into the socket (top)
of controller before running of controller, and lhen connect
battery with the controller. The thermoscopc \\ ill normally
work aftcr one minute. (Operate as indicated in the fourth
Chapter; thc environmental temperature of contruller will be
showed on I.e Il).
