GENERAL INFORMATION:
OVERVIEW
Adopting the advanced MPPT control algorithm, the solar controller can
minimize the maximum power point loss rate and loss time. It makes this
product tracks the PV array's maximum power point and obtains maximum
energy under any situation. Compared with the PWM charging method,
MPPT solar controllers can increase the energy utilization ratio by 10%-30%.
Charging current limit, charging power limit, and high temperature charging
automatic power reduction; these functions fully ensure system stability
when access to excess PV modules and high temperature running. Increase
a professional protection chip for the RS485 port, which further improves the
reliability and meets the dierent application requirements.
Based on a digital control circuit, the controller owns a self-adaptive
three-stage charging mode. It can eectively prolong the battery lifespan
and significantly improve the system's performance. They are equipped
with comprehensive electronic protections to ensure the solar system
more reliable and more durable. This controller can be widely used for RV,
household systems, field monitoring, and many other applications.
