20a Mppt Solar Charge Controller 12v 24v With Lcd Display - China

Maximum Power Point Tracking solar charge controllers (MPPT) are different than the traditional PWM solar charge controllers in that they are more efficient and in many cases more feature rich.

MPPT solar charge controllers allow your solar panels to operate at their optimum power output voltage, improving their performance by as much as 30%.

Traditional solar charge controllers reduce the efficiency of one part of your system in order to make it work with another.

Features

1 - High-speed MPPT high technology: MPPT with LCD display, efficiency > 99%, Employs a DC converting circuit, conversion efficiency > 96%.

2 - More selections for your need: five output modes: Manual, Standard, Timer, Light sensor, the Light sensor on + Timer off.

3 - Advanced electronic protection: overcharge, over discharge, overload and short circuit protection.

4 - 3-stage charging algorithm, impulse, bulk and float.

5 - Power meter function: LCD display shows the battery voltage, charging current, charging power, output status.

6 - Built-in timer, suitable for a periodic discharge system such as solar street lights, solar pumps etc.
