4.FAQ

1 What is the difference between PWM and MPPT charge controller?

"PWM charge controllers rely on an older technology. These controllers work to match the voltage from the solar panels to battery's voltage by pulling down the panel's voltage,  in doing so, it lowers the efficiency of the energy to about 80% of the theoretical maximum.

MPPT is a newer technology designed for extracting maximum energy from the solar panel, by maintaining the highest possible voltage from the panel. It can achieve high efficiency rate of 98%."  


2 How is your quality?

CARSPA has successful implemented ISO9001 and a strict quality control process throughout the production process. In addition, we use ATE testing equipment for testing and we keep test data for as long as 5 years.


3  What's the delivery time?
It depends on your quantity, but usually, 7 days for sample order, 30-45 days for batch order.


4 What is your regular package? 

Our regular package is color box or brown box, then packaged in cartons.  


5 How long will it take to develop a new product?

Usually it takes about 60days to develop a new product.
