General Information

2.1. Overview

The MPPT PRO-X solar charge controllers represent the new generation of Offgridtec MPPT charge
controllers and were developed in cooperation with the company EPSolar Technology. The function
of limiting the charging power and current, as well as the automatic reduction of the charging power,
increase the stability even when connecting oversized PV modules and at high temperatures. The
IP33 rating and isolated RS485 design improve the reliability of the controller and meet the
requirements of various applications.
With its optimized MPPT control algorithm, PRO-X series controllers can minimize the MPP loss rate
and MPP loss time, track the maximum power point (MPP) of PV system quickly and accurately, get
the maximum energy from solar modules under all conditions, and increase the energy utilization
ratio in solar system by 10-30% compared to PWM charging method.
PRO-X series controller owns a three-stage charging mode, which can effectively prolong the battery's
lifespan and significantly improve the system performance. Comprehensive electronic protection of
overcharge, over-discharge, PV & battery reverse polarity, etc., ensures the solar system is more
reliable and durable. This controller can be widely used for RV, household systems, field monitoring,
and many other applications.
