1 What is your production capacity for inverters?

It's about 200,000 units per year.  

2 What is the difference between PWM and MPPT charge controller?

"PWM charge controllers rely on an older technology. These controllers work to match the voltage from the solar panels to battery's voltage by pulling down the panel's voltage,  in doing so, it lowers the efficiency of the energy to about 80% of the theoretical maximum.

MPPT is a newer technology designed for extracting maximum energy from the solar panel, by maintaining the highest possible voltage from the panel. It can achieve high efficiency rate of 98%."  

3 What is the lead time?

It depends on quantity. Usually 7days for sample, 30 working times for batch order.

4 Do you offer OEM service?

Yes, we have many OEM customers.

5 Do you have offices in Shenzhen?

Yes, we have a R&D center in Baoan, Shenzhen.It is mainly for hardware designing.
