Q

What is the difference between MPPT controller and PWM controller?

The MPPT controller has Max.PV open circuit voltage reach 150VDC, charging efficiency 30% higher than PWM, automatically match various voltage of 12V/24V/48V.

The PWM controller is weight light, intelligent and economic, automatically match various voltage of 12V/24V.

Q

What is the difference between high frequency inverter and low frequency inverter?

High frequency means from about 300Hz down to 50Hz, low frequency is from 0Hz up to 50Hz.

Low frequency inverter comes with large power transformer, stronger and good for loading those home appliances which build-in motor, such as refrigerators, air conditioners, water pumps, etc. High frequency inverter has a small volume, light weight, economic and high efficiency.
