1. General Information
1.1 Overview
Based on common negative design and advanced MPPT control algorithm, with LCD
displaying running status, this product is artistic, economical and practical. Improving
the MPPT control algorithm further, it can minimize the maximum power point loss
rate and loss time, quickly track the maximum power point of the PV array and obtain
the maximum energy from solar modules under any conditions; and can increase the
ratio of energy utilization in the solar system by 10%-30% compared with a PWM
charging method. The limitation function of the charging power and current and
reducing charging power function automatic improve the stability which works even
connecting oversize PV modules and in high temperature, and increase the
professional protection chip for the communication port, further improving the
reliabilityand meeting the differentapplicationrequirements.
With the adaptive three-stage charging mode based on a digital control circuit, the
series controllers can effectively prolong the life-cycle of batteries, significantly
improve the system performance and support all-around electronic protection
functions, including overcharging and over discharging protection to minimize
damages to components of the system caused by incorrect installation or system
failure at the utmost, and effectively ensure safer and more reliable operation of the
solar power supply system for a longer service time. This modular solar controller can
be widely used for different applications, e.g., Communication base stations,
householdsystems,and field monitoring,etc.
