ePropulsion MPPT 35 - 10 User Manual

Notes

Do not puncture, throw, drop, bend or modify the Solar Charge Controller.
The controller should be used in well ventilated, dry, particle free environment.
The controller should avoid direct sun exposure.

The aluminum case is an important means of heat dissipation, thus should not
be covered.

Opening the housing of the charger without prior written consent of the
manufacturer voids the manufacturer’s warranty immediately.

Introduction

Thank you for purchasing ePropulsion Solar Charge Controller. This solar charge
controller is specially designed for SPIRIT Battery. Fast Maximum Power Point

Tracking (MPPT) technology (efficiency ≥99.9%) precisely positions the maximum

power point of PV cells thus drawing more Photovoltaic energy. With improved

system efficiency, the charging conversion efficiency reaches as high as 90%. The

controller is not only designed to work perfectly with a wide variety of solar panels

with input voltage ≤ 35V eg. ePropulsion Foldable Solar Panel, but also can get

power from other sources with input voltage of 12V DC.

Controller

If the red light blinks when well connected, it indicates the charger is in charging
mode. When fully charged, the light turns steady green.

The maximum input charging current is 10A, so if connected to a 12V power source,
the maximum input power will be 120w.

LED Indicator

There is a bio-colored LED indicating mode of the solar charger.
