15Amp Waterproof LCD Solar Controller

 

This regulator has some new features which will not only help maintain your battery charge but will also provide you with information so you are in control.

 

One of the features is the ability not to only show a battery voltage but this regulator will display FUL when the battery is fully charged. It takes the guess work out of knowing if your battery is charged or not.

 

In addition to this, by a simple press of the voltage button the Amps which are being input to your battery will display.

 

By pressing this button again the accumulated Amps output to your battery will be displayed.

 

This regulator will not only charge the standard AGM, GEL and FLOOD batteries it can also charge CALCIUM BATTERIES. Very few solar controllers will charge calcium batteries but this one will.
