3.Product feature and application of 3KVA solar Inverter

The Caspar KS series is a kind of hybrid solar inverter. The series of products are composed of inverter, solar controller, battery charger and UPS system. As a fashionable high-tech product, this system has LCD display function, realize the monitoring of system status.Press button to adjust the displaystatus and working mode. We have the system production settings default as the public power priority.When the city power is cut off, it automatically shift to the solar mode for power supply, to realize the uninterrupted power supply. For KS series, the built-in controller is PWM control.

-Rated power from 1KVA to 5KVA.

-Transfer time has 5ms, 10ms, 500ms, 10s optional.


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 into pure-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 efficiency rate 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.
