The product is the new generation of intelligent solar charge and discharge controller, it has strong stability and high service life. This series is 12V/24V automatic identification, with automatic detection battery voltage function, PWM charging way and comprehensive protection function: overcharge, over-discharge, over-current, short-circuit, reversed. Custom design about adjustable control parameters is accepted.

The solar controller has household type and street lamp type in the design of an organic whole.
The solar controller has 12V, 24V auto identification of the design.
