Product Q&A

Q:What is the difference between an inverter and a solar inverter?

An inverter only accepts AC input, whereas a solar inverter can accept both AC input and DC input from solar panels, which saves more power.

Q:What should be noticed when installing the inverter?

Install in a well-ventilated, cool, dry, and waterproof place. Do not stress it or put foreign objects inside. Turn on the inverter before the appliance.

Q:Do we need to set parameters before using the inverter?

No need. Preset parameters meet normal use. The inverter is AI intelligent. You can adjust parameters in a few simple steps if needed.

Q:What are the payment terms?

100% T/T in advance for sample orders. For bulk orders, 50% T/T in advance and the balance 50% T/T before delivery.

Q:What is your main market?

Our brands are well known in Europe, Africa, Middle East, Southeast Asia, and South America.
