FAQ
● Q: What's your quality control system?
A: We have strict quality control system from raw material procurement, production to product testing, every product is done fatigue testing, calibration, temperature compensation before shipment. High quality is guaranteed.
● Q: Can the input frequency of inverter be 50HZ and output frequency be 60HZ?
A: The input frequency and the output frequency are the same, if the input frequency is 50HZ, the output frequency is 50HZ.
● Q: What is lead time of your product?
A: We are factory, our lead time is about 24-46 working days.
● Q: Is the variable speed drive inverter rainproof? Can we put it outdoors?
A: No, this inverter is not rainproof, we can’t put it outdoors.
● Q: Can you provide packing details for this product?
A: For inverters power below 2.2KW, there are 6PCS in a CTN; for 4KW and 7.5KW inverters, there are 4PCS in a CTN.
● Q: What material is the shell of the regular knapsack inverter?
A: The base is aluminum alloy and the panel is plastic.
● Q: Why should I equip a pressure tank for while installing the inverter?
A: In order to keep the stopping pressure stable, and the water pump can stop normally.
