## Overview

The SolarEpic MPPT 40A Solar Charge Controller is a state-of-the-art battery regulator designed for optimal solar energy management. With a negative ground design and advanced safety features, it ensures efficient energy conversion and protection for your solar system.

## Description

If you need to monitoring the solar system or setting the controller, you may have to buy a MT-50 remote meter separately.      Description  The Tracer-BN series controller is for off-grid solar system and control the charging and discharging of the battery.  The controller features a smart tracking algorithm that maximizes the energy from the solar PV module(s) and charge the battery.  At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging.  The battery charging process has been optimized for long battery life and improved system performance.  The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults. In addition, the Tracer-BN series controller has a RJ45 interface to allow communication with other accessory.      Technical Data  Nominal system voltage: 12VDC / 24VDC Auto work  Rated charge current:40A  Rated discharge current: 20A  Max. solar input voltage:150VDC  Max.
