3.Product feature and application of MPPT charge controller without LCD

-The classical model of MPPT is aluminum casing,silver colour.The aluminum material and the intelligent cooling fan guarantee good heat dissipating,free you from the worry about overheat on product.

-Tracking efficiency is high as 99%,the solar power has never been used so efficiently.

-LCD digital display function offers a convenience to understand the working status in every stage timely,and it is possible to monitor and control the working status of the system and the battery as you wish.

-After many times of technology improvement,MPPT controller has become the backbone of CARSPA brand.And to meet the widely demand of the customers,carspa team has developed a controller which can charge Li-thium battery combining technology of MPPT and casing design of ENS series products,which opens up a broader space for opening market for CARSPA brand.


1. What products do you offer?

"CARSPA sells electric power related products, such as off-grid inverters, charge controllers, and battery chargers, and we also provide services for solutions to customer's unique situations and requirements.       

2. Tell me more about your inverter. What are the major function? 

Depending on the lines of products, our inverters invert DC intopure-sine-wave or modified-sine-wave 110V or 200V AC. They offers many safety features, such as, power overload protection , over-temperature protection, over-voltage protection. Also, we have other features to relieve human errors, such as short circuiting, and reverse polarity.

3. What is the difference between modified sine wave and pure sine wave?

"Both types of inverters will provide power to AC appliances, however Pure Sine is high quality equal to or better than the power in your home, Modified sine wave power is a simpler form of power and is adequate for simple electronics, but may damage more complex ones.

4. 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 efficiencyrate of 98%."  

5. 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.
