MPPT technology introduction:

MPPT means maximum power point tracking. It makes the solar panels work at maximum point(ext Point B) by using power conversion technology. eMPPT is the new charge controller researched and developed by our company, and it uses the MCU to track the maximum power point of solar panels intelligently to generate more power from the solar panels. 

MPPT Solar Charger Controller is a system with advanced MPPT (Maximum Power Point Tracking) Technology. The term “charge controller” refers either to a stand-alone device or a control circuitry integrated within a battery pack, battery-powered solar device or a battery recharger.

This photovoltaic charge controller is the key component in off-grid or stand-alone solar power generation systems. It can track the maximum power point and transfer energy to various types of batteries. The build-in MPPT microprocessor enables the Solar Charge Controller to increase the energy transfer efficiency by up to 30% compared to traditional charge controllers. Easy installation with parallel connection capability makes MPPT Solar Charger Controller the perfect solution for your home as well as any large solar system application.

Solar Charger Controller’s MPPT technology operates in a unique fashion. It calculates the maximum power voltage (V) at which the PV module delivers maximum power, and then the MPPT operates the module at a level, which extracts the maximum available power. The Solar Charger Controller continuously recalculates the maximum power voltage according to the changing operating conditions.

MPPT Controllers converts excess voltage into average. Converting excess voltage into Amps, the charge voltage can be kept at an optimal level while the time required to charge the battery is reduced.

MPPT Solar Charger Controller also regulates the rate at which electric current is added to or drawn from batteries. It prevents overcharging, over and variable voltage which if not controlled can reduce battery performance or life span and may pose a safety risk. It also prevents complete drainage (”deep discharge”) of a battery and facilitates controlled discharge thereby maintaining the battery’s longevity. Equipped with Micro controller and Digital Signal Processing (DSP) technology MPPT Solar Charger Controller is fully protected against transient over voltage and reverse the current flow, and can charge any type of battery.

(1) Maximum Power Point Tracking technology

The controller uses Buck conversion circuit and MCU technology to track the maximum power point to implement the maximum output power of solar panels in different illumination intensity and temperature. The MPPT algorithm increases efficiency of your PV system and decreases the quantity of solar panels.

(2) Multi-stage Charge Control

The starting charging voltage of battery is different, the controller will use the different charging strategies to finalize the charging process. When starting charging voltage of battery is lower than 12.4V (for 12V battery), battery will go through three stages as Bulk, Absorption and Float charging. When starting charging voltage of battery is higher than 12.4V (for 12V battery), battery will go through two stages as Bulk and Float charging.
