Solar Charge Controller, MPPT Solar Controller 48V

1. Introduction

This MRWS-MPPT30 20A solar controller (also known as MARS ROCK intelligent solar charge controller, solar charge controller, PV controller) can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by 10%-30%. MARSROCK MRWS-MPPT solar controllers 10A-60A include 12V series, 24V series and 48V series.

 

2, MPPT advantages

Maximum Power Point Tracking (MPPT in short) system is a system which allows PV panels to outputs more Power by adjusting working condition of the electrical module. If for the ordinary controller, which makes PV battery work on 12V ,only outputs a power point of 53W (a general power point), while. the MPPT controller makes PV battery always work at the maximum power point, thus outputs the power point of 75W (the maximum power point).

We also have passed ISO9001, CE and RoHS certifications. MARSROCK products can be designed and produced according to clients’ special request. Welcome agents from every area.

4. MPPT principle

The maximum power point is mainly affected by the ambient temperature and the intensity of sunshine. The intensity of sunshine being constant, the maximum output power decreases with the rise of the temperature. The temperature being constant, when the sunshine intensifies, the open circuit voltage of PV battery basically keeps unchanged. But the short circuit current increases substantially, thus the maximum output power increases substantially.

This MRWS-MPPT solar controller can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by about 30%.

However, due to many different factors, such as the difference in solar panel making, the change the Sun illuminance, change in temperature, the efficiency of the controller etc, the actually available increased rate is 10%-30%.
