1. Summary:
This series is a series of new intelligent multi-function solar charging controller. Its innovative design makes it easy to install, with friendly OS interface people can use this product easier. Optimized charge and discharge management can greatly extend the battery life. Meanwhile, the controller can display all system parameters, you can set every parameter to meet the various applications.
The controller can automatically identify 12/24/36/48V voltage level, the unique clock circuit allows the product to have more accurate load control capabilities, controller comes with remote communication function an be extended to a variety of host computers such as desktop computers, tablet PCs, Smart phones, etc. through cable, WIFI and Bluetooth, etc. to provide data transmission, external temperature sensor makes temperature compensation more accurate.
