About this item

The GS-MPPT-320W solar charge controller keeps batteries regulated and prevents them from overcharging and discharging. Applying an intellegigent MPPT algorithm, it allows the GS-MPPT-320W solar charge controller to extract maximum power from the solar array by finding the maximum power point of the array.


Increase your solar panel output with the Grape Solar MPPT charge controller. Intelligent algorithms harness more power from your solar panel. Three stage charging properly maintains your batteries to maximize their lifespan.

A convenient digital display shows instantaneous power production.  Audible alarms will let you know when your battery bank has low voltage or overloads. This charge controller is fully compatible with vented and sealed lead acid batteries as well as gel and NiCd batteries.
