Product Q&A

Q:How to choose the right inverter?

Tell us your demand, and our sales team at GUANGZHOU BEDFORD ELECTRIC EQUIPMENT CO.,LTD. will recommend a suitable inverter for you.

Q:What's the difference between inverter and solar inverter?

Inverters only accept AC input, but solar inverters not only accept AC input but also can connect with solar panels to accept DC input, making them more power-saving.

Q:How about the delivery time?

For sample orders, the delivery time is 3-5 days. For bulk orders, it takes 15-25 days.

Q:What is the warranty for inverters?

Our inverters come with a one-year warranty, while our VFD controlled pump (B1100 series) has a two-year warranty.

Q:What are the payment terms?

For sample orders, we require 100% T/T payment in advance. For bulk orders, we require 50% T/T payment in advance, with the remaining 50% to be paid via T/T upon completion.
