Its assets


The SRNE HP solar controller has an improved 3-step PWM charging algorithm. Periodic application of an equalization charge to the battery or during excessive discharge can effectively prevent the battery from not equalizing and causing sulfidation, which increases the battery life.

With the temperature compensation used, the charging parameters can be adjusted automatically.

A wide range of charge operating modes facilitate the application of the controller to different types of loads.

The PWN HP controller offers protection


• against overload
• against undervoltage
• against overcurrent
• against short circuits
• TVS against lightning

Thanks to an advanced load start method, high-capacity loads can be started smoothly.

The user-friendly design of the browser and dynamic interfaces on the LCD screen ensure practical and intuitive operations.

With its industrial quality design, the product can operate in various harsh conditions.
