Q1. What's the payment term?
A. We accept TT,30% deposit and 70% balance before shipment.
Q2. How's the delivery time?
A. It will take about 7-15 days for production
Q 3. What kind of material of transformer?
A. we have two types, one 100% copper and the other is copper with aluminum. It depends on your requirement. The pure copper has longer long life then aluminum one. Copper is better and also higer price.
Q4. Could you offer Form A or C/O ?
A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.
Q5. Would you accept to use our logo?
A. Welcome to do OEM.
Q6. We want to know month capacity.
A. It depends on which model. For example for relay type small capacity , month capacity can reach near 20000pcs and big capacity near 3000pcs.
Q7. Where is your market?
A. Our products are popular in USA, Egypt, South Africa, Middle East, Pakistan and so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutual benefit from our cooperation.
Q8. Does the inverter connect with solar system ?
A.Yes. Because of the unique feature which combine invert,charge and AC auto-transfer switch into one complete system,made inverter not only connect with solar system,also could be used in& officer equipment,household items,power tools ans etc..
Q9. What kind of certificate you have ?
A. Our company already achieve ISO, CCC, and for products, we have CE, SONCAP, GOST, UL(pending) .
