MPPT solar controller is designed for solar power system design; equipment can not only efficiently transfer issued by the solar panels to recharge the battery power, but also provide powerful control functions.  

Features: 
Characterized by intelligent adjustment of the operating voltage solar panels. 
Solar panel always working at the VA characteristic curve of the maximum power point. 
LCD display battery voltage and power. 
Professional digital intelligent control. 
Perfect protection. 
CE、RoHS testing approval.
