WARNING – IMPORTANT PLEASE READ
●Fully independent dual battery charging control, reduce the extra cost of two
separated solar charging system, ideal for Caravans, RVs, Boats and Cottages, etc.
●Charging priority preset, can select the percentage of available charge current to
each battery.
●Provide a wide range of Battery type setting for each battery: Gel, AGM,
Conventional lead-acid (WET), Calcium, LiFePO4, LTO (Lithium Titanium Oxide)
Battery types selection.
●Industrial grade MCU control, Pulse width modulated (PWM) technology, high
efficiency operation.
●Ensure charge current is not wasted, if the first battery is fully charged, more charge
current will be divided to the second battery, and return to the setting charging
automatically when the first battery is in low voltage.
●Built in regulator to prevent two battery from being overcharged. Overcharging
occurs when the charge voltage is unregulated. This can result in premature battery
failure.
●Come with regulator to prevent two 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.
●Protects two 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 each battery and into
the solar panel.
●Colored LED’s to easily indicate the operational status and each battery conditions.
●Digital LCD to directly display each battery voltage, charging current, charging
capacity, percentage preset, battery type, ambient temperature 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-coated circuit boards and plated terminals apply to hostile environments.
FEATURE

3
● 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, LiFePO4 or LTO 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.

Wire < 1m 6m 9m 12m
Size (AWG) 8 or 6 10 8 6
Installation procedure:
1. Using the Terminals supplied, crimp the terminals on your Battery wires.
2. Connect together the Negative polarity of solar controller “-“, BAT1 “-“ and BT2 “-“
3. Connect the solar controller “BT1+” to the Positive polarity of Battery “BT1+”
Connect the solar controller “BT2+” to the Positive polarity of Battery “BT2+”
4. Using the Terminals supplied, crimp the terminals on your Solar Array wires and
connect to the Solar Panel “+” to the solar controller “+” like shown.
NOTE: The 40Amp inline fuses must be connected into the positive wires as shown.
Caution 1: If BT1 and BT2 are different battery type or setting, please do not
confuse or reverse the connection of BT1 or BT2 to the controller, otherwise
may damage your battery.

Caution 2: The dual battery controller installation must be made by
specialized technique person, any wrong size of wires used or loose power
connections or corroded wires can melt wire insulation, burn surrounding
materials or even cause a fire. Ensure tight all connections and use cable
clamps to secure cables.
NOTE: The dual battery controller has a common negative, it does not matter which
Negative terminal is grounded.
When the connections are completed, the Controller will start working automatically.
Charging priority setting: The dual battery controller provides the priority charging
setting for Battery 1# and Battery 2#; the user can select the percentage of available
charge current to each battery.
Press the Button BT1 and hold for 3 seconds until the number flashing, you can
select 10% into 90% setting via clicking BT1 button until you want, it will
automatically save the data after you complete the percentage setting, or you go
into the next Battery type setting by pressing and holding the button for 5 seconds.
Only need to set the charge rate percentage you want for Battery 1#, the controller
will automatically calculate the rest for the Battery 2#:
For example: Battery 1# is set at the charging rate percentage of 50%.
LCD will be shown % and indicated the pattern
Note: in the normal charging condition, the controller will divide the charging current
as your setting, while Battery 1# is fully charged; more charging current will be
diverted to Battery 2#, and return to the former setting automatically when the
Battery 1# is in need of charge.
When the controller detects there is only Battery 1# connected, the entire charging
current will go into the Battery 1# automatically.
Battery type settings:
Please check your battery manufacturer’s specifications to select correct battery
type. The unit provides six (6) battery types setting for selections: Gel, AGM, WET
(conventional lead acid), Calcium, LiFePO4 and LTO battery. Allow the different
battery type for each battery setting.
