Pwm Solar Charge Controller with LCD - 30A 12V/24V

solar wind30A Pwm Solar Charge Controller

30A Pwm Solar Charge Controller

Description: Powerful charge controller for photovoltaic applications, provided with an innovative system for calculating the state of charge through an effective adaptive algorithm "fuzzy logic". This calculation system (said SOC) has the function of guaranteeing the best charging process of the batteries and the correct display of the percentage of charge of the same batteries, thanks to a large and practical LCD display. If the charge value displayed is 100%, then it means that the batteries are fully charged. This controller for photovoltaic solar panels is able to automatically detect and charge both 12V batteries and 24V batteries and can handle currents up to 30A. It was developed and manufactured in Germany and presents the protections of overcharge, deep discharge, reverse polarity, short circuit and overvoltage. If you want to know what factors influence the correct choice of the charge controller, please visit the page "How to choose a solar charge controller".

Sequence of connections: First, connect the battery to the terminals of the controller through two power cables with section equal or greater than 6mm² and a length of less than one meter. Although the controller has protection from reverse polarity, pay attention to the connections! Then wait 15-20 seconds and connect the solar panel to the terminals of the controller. The output with the symbol of the light bulb (Load) The output with the symbol of the light bulb (Load) is used to power the battery voltage loads such as for example any of the bulbs. If you use a 12V battery, the maximum load shall not exceed 360W, whereas if you use a 24V battery (or two 12V batteries in series), the maximum load shall not exceed 720W. In the case where the battery voltage drops below a certain value (safety threshold), the loads connected to the output LOAD will be disconnected automatically by the controller. In this way, the controller provides maximum protection to the battery, safeguarding it against deep discharge.
