Charge controllers are generally used to extend the life of a battery in an energy system, by preventing it from overcharging and complete discharging. As a component of an off grid solar power system, a charge controller is required and regulates solar modules charging current. They can come in many different sizes and can offer many functions that can be specific to a design application and/or protection.
SW Energy has many different types of charge controllers designed to work with various systems.
Morningstar’s ProStar is a mid-range PWM battery charging solar controller for both professional and consumer applications. This second generation ProStar adds new features and protections using advanced technology, providing longer battery life and improved system performance.
The TriStar controller is a three-function controller that provides reliable solar battery charging, load control or diversion regulation. The controller operates in one of these modes at a time and two or more controllers may be used to provide multiple functions.
Solar lighting controller combines the SunSaver design with a microcontroller for automatic lighting control functions. SunLight’s technology provides high reliability, PWM battery charging.
BZ Products – MPPT 250
The MPPT series of charge controllers are fully automatic, current boosting, voltage converting solar controller. The MPPT series incorporates an advanced microprocessor design that brings outstanding performance and many new features to the medium power PV systems. The MPPT series includes universal PV input up to 100 volts and up to 500 watts PV input power.
The Steca PR controllers were launched in the year 2004 as the fifth generation of charge controller technology (up to 900 Wp). This high class state-of-the-art product upgrades the Steca Solarix series by a customer-designed LCD which show the accurate state of charge (SOC) in percent and as a battery gauge symbol.
