WARNING – IMPORTANT PLEASE READ
●Advanced MCU control pulse width modulated (PWM) technology, high efficiency
operation.
●Target for Gel, AGM, Conventional lead-acid (WET) 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.
●Come with regulator to prevent your battery from being under charged, in the solar
energy field, battery undercharge always occurs, especially on some Conventional
lead –acid or Calcium batteries; The unit provides an automatic Equalization feature
for deeply drained Conventional lead acid battery or Calcium battery, as well as
provides a cycling automatic Equalizing feature every 28 days.
●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 current flowing back from the battery and into the
solar panel.
●Colored LED’s to easily indicate the operational status and battery conditions.
●Digital LCD to directly display battery voltage, charging current, charging capacity
(Amp hour), battery types and faulty codes.
●Provides plug-in remote digital display meter (Optional).
●Provides external battery temperature sensor (Optional).
●Multi charging protections against reverse polarity, short circuit, over temperature,
over voltage, etc.
●Surface Mount or Flush Panel Mount options.
●Conformal-coating circuit boards and plated terminals apply to hostile environments.

● This charger is designed for indoor use only and should never be exposed
to rain.
● Do not disassemble the controller. 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) with some sort of soft cloth 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 following diagram, mark a 105mm x
130mm rectangle where you wish to mount the controller and cut-out the panel
opening then use the two self- tapping screws supplied to secure the unit.

4
To protect the Battery and the Solar Panel, we strongly recommend that you place a
40A 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.
When the connections are completed, the Solar Controller will start working
automatically.
Please check your battery manufacturer’s specifications to select correct battery type.
The unit provides 4 battery types for selections: Gel, AGM, WET (conventional lead
acid), and Calcium.
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.

Press BATTERY TYPE button and hold for 3 seconds to go into your battery type
selection mode, the battery type you select will be shown on the LCD meter, the
default setting is AGM Battery; the controller will automatically memorize your battery
type setting.
Caution: Incorrect battery type setting may damage your battery.
When the controller powers on, the unit will run self-qualify mode and automatically
show below items on LCD before going into charging process

The VOLT / AMP button can be changed at any time during charging process.
The LCD also can be treated as an independent voltage meter or thermometer.
A voltage less than 11.5V Volts indicates that the battery is discharged and needs
re-charging.
The unit has a 5 stage charging algorithm.
Soft Charge (Level 1) –Bulk Charge (Level 2)-Absorption charge (Level 3) –
Equalizing Charge* (Level 4) - Float Mode (Level 5)
CHARGING STAGES

6
Soft Charge- When batteries suffer an over-discharge, the controller will softly ramps
the battery voltage up to 10V.
Bulk Charge-Maximum current charging until batteries rise to Absorption level
Absorption Charge-Constant voltage charging and battery is over 85%.
Equalization Charge*-Only for WET battery or Calcium battery type, when the battery
is deeply drained below 10V, it will automatically run this stage to bring
the internal cells as an equal states and fully complement the loss of
capacity.(Gel and AGM battery do not run Equalization charge)
Float Charge-Battery is fully charged and maintained at a safe level.
A fully charged battery has a voltage of more than 13.6 Volts.
