READ MANUAL BEFORE USING THIS PRODUCT
1. PRODUCT INTRODUCTION
This AIMS Power PWM solar charge controller is designed to charge and monitor your LiFePO4 battery
to achieve a longer life cycle. It also trickle charges AGM, GEL and lead acid battery technologies.
Using the latest charging technologies combined with state of charge monitoring, this product allows
for optimal battery maintenance and efficient solar power monitoring. The LCD screen displays
operating modes such as; state of charge, voltage, and current. The product also displays symbols for
easy user interface.
Integrated data logger energy meter
Automatic detection of voltage 12 or 24 Vdc
PWM control
Automatic load reconnection
Listed to UL 1741 & CSA 22.2 No. 107.1
Adjustable charge voltage
2. INSTALLATION
Install the charge controller near the battery on a
stable
surface. This surface should be solid, even, dry
and nonflammable. The battery cable should be as short as possible and have a cable diameter size to
minimize loss, e.g. 4 mm² at 20 A and 6ft in length (16 AWG).
Do not install the controller in direct sunlight.
To ensure adequate airflow around the controller, allow a 4 inch clearance around the unit. The
temperature at the installation site may never fall below or exceed the maximum
permitted ambient
temperature range.
Connect the individual components to the symbols provided on the bottom of controller.
Follow the following connection sequence during installation:
1. Connect the battery to the charge controller - positive and negative
2. Connect the solar module to the charge controller - positive and negative
3. Connect the DC load to the charge controller – positive and negative (optional)
The reverse order applies when uninstalling.
NOTE! The automatic detection of 12V or 24V systems functions properly only if this sequence
order is followed. An improper sequence order can damage the battery!
*There are no user serviceable parts inside the charge controller. Do not disassemble or attempt
to repair the unit. Contact manufacturer.

3.2 Description of Button Function
Button for switching display windows
Enter/exit the setting (press for 5 seconds)
Adjust parameters up
Restore factory setting in each parameter (press for 5 seconds)
Adjust parameters down (minus)
Click this button to switch the load in main display
window
3.3 View and Set the Parameters
The controller will auto display the “battery voltage” main display once power is connected (follow
correct sequence from INSTALLATION instructions. This is the main display window. Use the button
to switch between different display windows. If the parameter can be set, press the button
(>5 seconds, numbers start flashing) to enter the setting, then press the
or
to
select the setting, after that, press the button (>5 secs)
again to exit the setting (numbers stop
flashing).
