●Advanced MCU control pulse width modulated (PWM) technology, high efficiency
operation.
●for LiFePO4, LTO (Lithium Titanium Oxide), LI-95, Gel, AGM, Conventional
lead-acid (WET) Batteries.
●Integrated regulator to prevent your battery from being overcharged. Overcharging
occurs when the charge voltage is unregulated. This can result in premature battery
failure.
●Integrated regulator to prevent your battery from being under charged, The unit
provides an automatic Equalization feature for deeply drained Conventional lead
acid 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’sto 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.
For use with 12/24Volt Solar Panel; Suitable for Solar panels up to
760 Watts on 12V mode; 1520Watt on 24V mode

●
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, LiFePO4, 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
WARNING – IMPORTANT PLEASE READ
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.

To protect the Battery and the Solar Panel, we strongly recommend that you place a
50A 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’.

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 6 battery mode for selections:LiFePO4, LTO, LI-95, Gel, AGM, WET
(conventional lead acid).
Correct Wire Size:
Please refer to the wire size chart
below to determine the minimum
size wire needed for each
connection. Thiswill 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.

The VOLT / AMP button can be changed at any time during charging process.
You also can visually monitor your battery charging condition for each battery; there is
a LCD bar to show the percentage of charge, you can easily see the battery is charged
to 25%, 50%, 75% or 100%.
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- When batteries suffer an over-discharge, the controller will softly ramp
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 type, when the battery is deeply drained
below 10V, it will automatically run this stage to bring the internal cells as
an equal state and fully complement the loss of capacity. (LiFePO4, LTO,
LI-95, Gel and AGM battery do not run Equalization charge)
Float Charge-Battery is fully charged and maintained at a safe level.
A fully charged Lead acid battery (GEL, AGM, WET battery) has a
voltage of more than 13.6 Volts; A fully charged LiFePO4 or LTO battery
has a voltage level of 13.4V.
Lithium batteries wake-up-If the BMS under-voltage protection has been triggered in
the lithium battery mode (LiFePO4, LTO or LI-95 ) , Pressing both VOLT/AMP
and BATTERY TYPEbutton, the solar controller will wake up the "dead" Lithium
batteries, The LCD display will showthe rotation of moving bar in this wake-up period.

The controller provides two optional devices ( excludes in the packaging box).
Optional external Battery temperature sensor:
As an option, the unit provides a port to connect the external battery temperature sensor;
if the external battery temperature sensor is connected, the unit will optimize the chargin g
performance subjected to the battery temperature detected and also provide the battery
over temperature protection, in some cases, if battery over temperature occurs, the
controller will automatically stop charging.
Optional external Remote display meter:
As an option, the unit also provides a port to connect the external Remote display meter
for some special location needed. The display content on the Remote meter is same as
the display on the controller.
