4.FAQ

1. When was Carspa founded?

CARSPA was founded in 2004 focusing on the production of power inverters, solar charge controllers, battery chargers.


2. What is PWM?

PWM charge controllers work to match the voltage from the solar panels to battery's voltage by pulling down the panel's voltage, so the efficiency of the energy is only about 80% of the theoretical maximum.


3. What is the difference between PWM and MPPT charge controller?

PWM efficiency is only about 80% , MPPT efficiency rate is 98%."


4.  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
