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 control-
ler can increase solar charge utilization in excess of 30%
overpulse 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.

FEATURES
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.
