What Our Customer Say

When I was looking for suppliers in China, I visited Sunflx's website then contacted them and came to their company to discuss cooperation. They have many product models and also support customize, I ordered 200 units of off grid inverters and started using them when I returned to my country. They’re working really well till now.

I think it is wise to use Sunflx inverters in Pakistan. Their inverters are durable and they also have good prices with efficient service. Their off grid inverters are easy to use and cost lower than others, They perfectly fit my requirements.
