WARNING
• Please read these instructions completely prior to installation.
• Lead acid batteries can be dangerous. Ensure no sparks or flames are present when
working near batteries. Eye protection should be used. If mounting on a vehicle follow
all manufacturers’ instructions.
• Given sufficient light solar panels always generate energy even when they are
disconnected. Accidental ‘shorting’ of the terminals or wiring can result in sparks
causing personal injury or a fire hazard. It is recommended to cover the front face
of the panel(s) with a soft cloth to block incoming light during installation.
• For use with 12V or 24V (nominal) solar panels.
• For indoor, out of weather use only.
• Do not exceed the total limit of the solar controller –
P/No. SC310: 120W/10A
P/No. SC320: 240W/20A
FEATURES
3 STAGE CHARGING
Ideal for deep cycle batteries, SC310 & SC320 deliver 3 stage charging, maximising
battery life and performance. The in-built temperature sensor adjusts the output
guaranteeing a thorough charge in all conditions.
• aintains your battery ready for use
• Safe to leave permanently connected
• Prevents solar over-charge/discharge
LOW VOLTAGE DISCONNECT (LVD)
LVD will disconnect the DC load before the battery voltage falls too low, preventing
damage due to over-discharge. Once the battery is recharged, the DC load will be
automatically reconnected.
LOAD CONTROL
The SC310 & SC320 allow you to switch the DC load on/off from the controller without
having to physically disconnect the load or appliance. When switched to ‘off’, the DC
load is isolated from the battery ensuring maximum power conservation.
ELECTRICAL PROTECTION
• Short circuit & over current protection
• Reverse polarity protection
• Conformal coated for protection against dust and moisture

INSTALLATION
Projecta solar controllers are designed for indoor, out of weather use only.
ount to a suitable flat surface as close to the battery as possible and away from
moving parts or high temperature components. Ensure there is clearance around the
controller to allow for adequate ventilation.
The controller terminals are illustrated for easy identification:
Ensure connections are made to the correct terminals and polarity.
1. Connect the b ttery to the solar controller using suitable cable. It is recommended
to install a fuse close to the battery positive terminal. When correctly connected,
the Battery L.E.D will illuminate.
2. Connect the sol r p nel to the solar controller using suitable cable.
When correctly connected and in sunlight, the Solar L.E.D will illuminate.

C ution:
Given sufficient light solar panels always generate energy even when they are
disconnected. Accidental ‘shorting’ of the terminals or wiring can result in sparks
causing personal injury or a fire hazard. It is recommended to cover the front face
of the panel(s) with a soft cloth to block incoming light during installation.
3. Connect the lo d or ppli nce to the solar controller.
When first connected, the Load is switched to ‘On’. If correctly connected the
Load Off/On L.E.D will illuminate and the load/appliance will be on. To turn the
appliance off/on, press the Load Off/On button.
OPERATION
The solar controller will automatically begin to charge and maintain the battery.
The temperature sensor will automatically adjust the charge output according to
the ambient temperature.
During operation, three L.E.Ds indicate the operation status.
