Solar Controller / Battery Charger
Input: DC12V Solar Panel (Max. 25V)
Output: DC12V 30A
Model Number: OC-SR30
User’s Manual and Important Safety Information
Congratulations on purchasing an OzCharge Solar Controller Regulator.
OzCharge Controllers are comprised of the latest technology and suited to Aussie conditions:
Please carefully read these instructions before installing and using this device.
FEATURES
• Suits Gel, AGM, Conventional lead-acid and Calcium Batteries.
• Built in regulator to prevent your battery from being overcharged. Overcharging occurs when the charge voltage is
unregulated. This can result in premature battery failure.
• Can be connected to the battery permanently to keep the battery fully charged by using a process called “floating”.
This means the controller will stop charging when the battery is full and will automatically start charging the battery
as required. This process will also reduce water loss and help prevent the battery from ‘drying out’.
• Protects your battery from discharge at night. Under low light or no light conditions the solar panel voltage could be
less than the battery voltage. The unit contains a special circuit which prevents cu rrent flowing back from the
battery and into the solar panel.
• Coloured LED’s to indicate the operational status when there is power from the solar panel.
• Digital LCD to indicate battery voltage / current.
• Surface Mount or Flush Panel Mount options.
For use with 12 Volt Solar Panels Only.
Suitable for Solar Panels up to 510 Watts.

WARNING – IMPORTANT PLEASE READ…
• This device is to be used with 12V (nominal) Solar Panels only and the Panel(s) should not exceed 510W (30A)
(total) limit.
• This charger is designed for indoor use only and should never be exposed to rain.
• Do not disassemble the charger. Take to a qualified person if the unit requires repairing.
• Lead acid batteries can be dangerous. Ensure no sparks or flames are present when working near batteries.
• Eye protection should always be used. Never short circuit the battery
• 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. We recommend that you
cover up the panel(s) wit h some s ort of soft clot h so you can block all incoming light during the installation. This will
ensure that no damage is caused to the Solar Panel or Battery if the wires are accidentally short circuited.
• Always install a battery fuse on each circuit including the solar controller
• Do not reverse connect the wires to the solar panel or battery.
MOUNTING THE DEVICE
The Solar Controller has two mounting options.
1. Surface mount:
The quickest and easiest way to mount the unit is to use the two plastic spacers and self tapping screws supplied and
mount the unit to a flat surface,
2. Flush (panel) mount:
Before deciding to use this mounting method, please ensure there is sufficient depth behind the controller or in the
cavity. (Refer to Diagram below)
Using the dimensions shown in the followi ng diagram, mark a 95mm x 159mm rectangle where you wish to mou nt the
controller and cut-out the panel opening then use the two self- tapping screws supplied to secure the unit.
Note: You can use the card insert from the packaging as a guide for the CUT OUT.

WIRING CONNECTIONS
To protect the Battery and the Solar Panel, we strongly recommend that you place a 30A inline fuse on the positive
wire on both the “Solar” and “Battery” Circuits. (As close to the Battery / Panel as possible)
The Solar Controller has 4 terminals which are clearly marked ‘Solar’ and ‘Battery’.
There is a (12V) and earth (GND) terminal for each circuit.
Refer to the wiring diagram below.

1. Using the Terminals supplied, crimp the terminals on your Solar Array wires and connect to the Solar Panel like shown.
2. Using the Terminals supplied, crimp the terminals on your Battery wires and connect to the Battery like shown.
OPERATION – L.E.D INDICATORS
When the connections are completed, the Solar Controller will start charging the battery automatically.
The unit has a 3 stage charging algorithm.
Bulk Charge (Level 1) –Constant Voltage (Level 2) – Float Mode (Level 3)
Please check your battery manufacturer’s specifications to ensure the Boost Voltage switch is on the appropriate
setting. Boost Voltage – Is the maximum Voltage used to charge a battery.
Typically for Gel and AGM batteries you would need to select 14.4V.
For all other Conventional and Calcium batteries, you would need to select 14.7V.
The 6 LED’s indicate the charging status and
the battery condition

A voltage less than 11.5 Volts indicates that the battery is discharged and needs re-charging.
Digital LCD Meter – This can either display the battery voltage, the charging current or it can be switch off.
This switch maybe changed at any time during the charging process.
CHARGING CURVE (VOLTAGE)
Correct Wire Size:
Please refer to the wire size chart below
to determine the minimum size wire
needed for each connection. This will
also ensure you get the best
performance out of your solar regulator.
