Description
Your Expion360 Solar Charge Controller utilizes maximum
power point tracking (MPPT) technology to optimize the
energy captured from the sun. Solar charge controllers
are essential to convert the energy from the solar panel(s)
into energy that can be used to charge the batteries in
your chosen energy storage solution. Our MPPT charge
controller can increase solar charge utilization in excess
of 30% more than pulse width modulation (PWM) charge
controllers. This translates to faster charging times using
the same solar panels and more energy to power your
adventures!

SAFETY
Safety Instructions
1. Please read the manual carefully before using the
charge controller.
2. There are no parts inside the controller that can be
maintained or repaired. The user will void the warranty
if the controller is disassembled.
3. Install the controller indoors to prevent exposure
of components and prevent water from entering the
controller.
4. Please install the controller in a well ventilated area to
prevent the heat sink from being overheated.
5. Protecting the charge controller with a fuse or circuit
breaker is recommended.
6. Disconnect the PV input at the fuse or circuit breaker
near the battery terminal prior to installation or
adjusting any wiring at the controller.

Lithium Charging Prole
Charging your Expion360 lithium batteries with our MPPT
solar charge controller is the optimal way to deliver
energy. As the voltage of lithium batteries increases
with additional charge from the charge controller, the
MPPT technology is able to adjust the output current to
maximize utilization of the solar power. Once the charge
controller reaches the end of the constant current stage,
the controller will automatically switch to constant voltage

Installation
Step 1: Choose an installation location
Avoid installing the controller in a location with direct
sunlight, high temperature, and water, and ensure good
ventilation around the controller.
Step 2: Mark the mounting position
According to the mounting dimensions of the controller,
drill 4 mounting holes of the appropriate size at the
4 marks. Fix screws into the upper two mounting holes.

WARNING: Danger, explosion hazard! Never
install the controller and a vented battery in the
same enclosed space! Also, do not install in an
enclosed place where battery gas may collect.
WARNING: Danger, high voltage hazard!
Photovoltaic arrays may generate very high,
open-circuit voltages. Disconnect the circuit
breaker or fuse before wiring and be very
careful during wiring.
CAUTION: When installing the controller,
ensure there is enough air to ow through the
controller’s heatsink, leaving at least 6 inches
above and below the controller for natural
convection. If installing the controller in a
closed box, ensure reliable heat dissipation
through the box.


Input power limited protection
If the power of the solar panel is higher than the rated value,
the controller will limit the power of solar panel to prevent
over current damage. Controller enters current-limiting mode.
Battery reverse polarity protection
If the battery polarity is reversed, the system will not
be operational.
PV input overvoltage protection
If the voltage at the PV array input is too high, the controller
will automatically shut off the PV input.
PV input short circuit protection
If the voltage at the PV array input is short-circuited, the
controller will turn off charging. Once the short circuit is
removed, charging will automatically resume.
PV input reverse polarity protection
If the polarity of PV array is reversed, the controller will not
be damaged. Normal operation will continue after wiring is
corrected.
TVS lightning protection
If a lightning strike were to hit the PV array, the controller will
protect the connected circuit from the high voltage spike.
Over-temperature protection
When the temperature of the controller becomes too warm,
the controller will throttle the charging rate or stop charging.

System Maintenance
In order to maintain the best long-term performance of your charge
controller, it is recommended to conduct the following inspections
twice a year.
• 
Remove any visible dust from the heat sink with a vacuum or
compressed air.
• Verify that all exposed wires are undamaged due to friction
with nearby objects, dry rot, destruction by insects or rodents,
etc. These are common sources of unexpected damage to
electrical devices. If any damaged wires are found, repair or
replace the wires immediately.
• Check all wiring terminals for corrosion, insulation damage,
signs of high temperature or burning/discoloration. Tighten
terminal screws if there are signs of burning or discoloration
after replacing the wire.
WARNING: Danger, electric shock hazard! Make sure that all power
supplies to the controller have been disconnected before maintenance!
