Apart from it, we can also provide ODM and OEM services of solar energy system for our customers. You could kindly leave your contact on our company website, so we could send you our factory video.

      Q
      Where is your factory? Can I visit your factory?

      Located in Guangdong Province, China. Yes sure, we can arrange and make an appointment in advance for you.

      Q
      Can send me a sample for free?

      Yes, you could kindly purchase and pay it first, we will reduce this cost on your next order.

      Q
      Do you accept OEM?

      Yes.

      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.
