Q1.Would you accept to use our logo on your PWM solar controller?
If you have good quantity, it is absolute no problem to do OEM.
Q2.We want to know month capacity of PWM solar controller 40A.
It depends on which model. For example, relay type small capacity, month capacity can reach near 200000pcs and big capacity near 30000pcs.
Q3.Where is your market?
Our products are popular in Russia, Indonisia, Philippines, Italy, America, 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 mutural benifit from our cooperation.
Q4.Does the PWM solar controller connect with solar system ?
Yes. Because of the unique feature that combine inverter, charge controller and AC autotransfer switch into one complete system, it can make inverter not only connect with solar system, but also could be used in office equipment, household items, power tools etc.
Q5.What kind of certificate you have ?
Our company already achieve CE. Any certificate can apply for you.
Q6.What is OEM?
Original Equipment Manufacturer.
Q7.How long of the warranty or guaranty?
Q8.How to pay?
We accecpt paypal, western union, T/T. If you have any good payment, we also can accept.
