Thank you for choosing Grape Solar. This MPPT solar charge controller is a device for solar charge
regulation and direct current output load control. This device is mainly used in small and medium
sized off-grid solar power systems.
The Grape Solar Zenith series MPPT charge controllers have these features:
By continuously checking solar panel power output changes, the Zenith controllers employ
multiple MPPT charge algorithms in combination to boost charging efficiency in different
weather and temperature conditions.
Built-in buffer of 25% exceeding rated current input.
Charging modes available for most common deep-cycle battery types in the market, including
AGM (sealed lead acid batteries), GEL, Flooded, and Lithium. With the Grape Solar blue tooth
controller mobile phone application, additional setting parameters may be adjusted to meet the
needs of any other specialty batteries.
