SW SHS050W User Manual - page 5
Connect the wires leading to the battery with
correct polarity. To avoid any voltage on the
wires, first connect the controller, then the
battery. Keep in mind the recommended wire length
(min. 30 to max approx. 100 cm) and the wire size:
CA06-2: min. 2.5 mm
2
WARNING: If the battery is connected with reverse polarity, the charge
controller will also give the wrong polarity on the load terminals.
Never connect loads in this situation!
Connect the wires leading to the solar array with
correct polarity. To avoid any voltage on the
wires, first connect the controller, then the solar
array. Keep in mind the recommended wire size:
CA06-2: min. 2.5 mm
2
REMARK: place positive and negative wires leading to the solar
generator close to each other to minimize electromagnetic effects.
Connect the wires leading to the loads with correct
polarity. To avoid any voltage on the wires, first
connect the wire to the load, then to the
controller. Keep in mind the recommended wire size:
CA06-2: min. 2.5 mm

Starting up the Controller
System Voltage
The controller is intended for use at 12 V system voltage.
Battery Type
The controller does not generate an equalization charge, and is therefore suitable for use with lead acid
batteries with liquid electrolyte (vented battery) and lead acid batteries with solid electrolyte ('gel' or
'fleece' type).
Recommendations for Use
The controller warms up slightly during normal operation.
The controller does not need any maintenance or service. Remove dust with a dry tissue.
It is important that the battery gets fully charged frequently (at least monthly). Otherwise the battery
will be permanently damaged.
A battery can only be fully charged if not too much energy is drawn during charging. Keep that in mind,
especially if you install additional loads.
Display Functions in normal operation
The controller is equipped with 3 LEDs for display of the operating status.
Charge display
Battery voltage display
Load status display
In normal operation mode, the controller displays the charging status, the status of battery voltage and the
status of the load output.
