The MPPT series controller is suitable for off-grid solar 

applications. It protects the battery from being over-charged by the solar modules and over-discharged by the loads. 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 MPPT Charge Controller 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 charge controller has an RJ45 interface to allow communication with a Tracer meter for remote monitoring.

 

Key Features

1. Using Single Chip Microcomputer and specialized software make it smart control.

2.With over-charge, over-discharge, short-circuit, over-load protection, and specialized anti-reverse protection; above protections will not damage any parts, and do not burn insurance.

3.The controller is made by MPPT technology, the voltage loss the charging circuit is less nearly half than using diode charging circuit, charging efficiency is 3% higher than Non-MPPT, increases the power use of time; the improving charge of Discharge recover, normal direct charge, floating automatic control mode will extend the battery life

4.Intuitive LCD display interface, allowing users to understand the use of the situation. Well.

5.All controls are made by the industrial-grade chip, can run freely in cold, high temperature, humid environment.

6.One stop solution design with a key operation, to make it more easy and convenient to use 

7.Built in 12V/24V battery automotive identification function

 

MPPT Technology

The MPPT Charge Controller utilizes Maximum Power Point Tracking technology to extract maximum power from the solar module(s). The tracking algorithm is fully automatic and does not require user adjustment. MPPT technology will track the array’s maximum power point voltage (V) as it varies with weather conditions, ensuring that the maximum power is harvested from the array throughout the course of the day.

WARNING: Connect battery terminal wires to the charge controller FIRST then connect the solar panel(s) to the charge controller. NEVER connect solar panel to charge controller before the battery.

 

WARNING: Do NOT connect any inverters or battery charger into the load terminal of the charge controller.

 

WARNING: Once equalization is active in the battery charging, it will remain in this stage as long as there is adequate charging current from the solar panel. There should be NO load on the batteries when in equalization charging stage.

Maintenance

WARNING: Risk of Electric Shock! Make sure that all power is turned off before touching the terminals on the charge controller.

For best controller performance, it is recommended that these tasks be performed from

time to time.

1.Check that controller is mounted in a clean, dry, and ventilated area.

2.Check wiring going into the charge controller and make sure there is no wire

damage or wear.

3.Tighten all terminals and inspect any loose, broken, or burnt up connections

4.Check to make sure none of the terminals have any corrosion, insulation damage,

high temperature, or any burnt/discoloration marks.
