Charging with the intelligent PWM dim way and charging compensation in accordance with the current temperature of the battery, compensation factor is 3mv/℃/unit.LCM could show all of the parameters and modes.

 

 

 

 

 

mt20aSR-MT20A
A solar controller is an advanced MPPT controller with a built-in MPPT tracker and tracing algorithm, it’s easy for tracing the maximum power point for maximum solar power which can Increase the efficiency and decrease the system cost.

 

 

 

 

 

mt30a

SR-MT30A
The full name of the MPPT is maximum power point tracking. It is an advanced charging way which could detect the real-time power of the solar panel and the maximum point of the I-V curve that make the highest battery charging efficiency.

 

 

 

 

mt45a

SR-MT45A/60A
Generally speaking, the MPPT controller’s energy utilization efficiency is 15%~20% higher than PWM controller. The MPPT efficiency can reach 99.97%.
