Our solar controllers are designed for solar home system, ideal for rural electrification systems,and many advantages compared to other controllers:
Low Cost
Solar controller has specifically designed to meet the needs of the rural electrification market. The low cost resulted from using the latest electronic technology and high volume manufacturing.
High Reliability
We are manufacturer of solar charge controllers,power inverters,and solar power systems. All our products are designed for high quality and high reliability. The controller has a low failure rate and will last a long time, and got very good feedback from customers until now.
Electronic protections
The solar controllers are built-in electronic fused that do not require replacements.
Tropicalization
The solar controlers electronics are protected with moisture-tight coating, minimizing damage from humidity and from nesting insects.
Easy to use
Solar controller is fully automatic and requires no adjustments or user selections.
