*** If for any reason you are not satisfied with this purchase, kindly let us know, we will offer a replacement or full refund without any cost from your side!***

Make sure your battery must be atleast 60% charged prior to connecting to controller, or controller can’t read your battery’s voltage correctly.
Connect the battery to the controller first (When battey LED power on, means controller read battery successfully, if not please reconnect it.)
Connect your solar panel array to the controller after Controller’s LED power on.
Careful your input power and voltage does not exceed the max.
