GRANKIA CMS intelligent rv 12v 24v mppt charge controller 30a-60a can be compatible with various Deep Cycle battery options: Sealed, Gel, Flooded, and Lithium or User-defined.
The solar charge controller is used in off-grid solar systems (stand-alone) to automatically adjust battery charging and discharging. MPPT solar charge controller has an advanced tracking algorithm to obtain the maximum power of PV module to charge the batteries.
Maximum power point tracking (MPPT) is a technique used with variable power sources to maximize energy extraction as conditions vary.
The central problem addressed by MPPT is that the efficiency of power transfer from the solar cell depends on the amount of available sunlight, solar panel temperature and the load's electrical characteristics.
CME series solar charge controller automatically detects 12V/24V DC system voltage. Innovative MPPT technology with high tracking efficiency up to 99.5% and peak conversion efficiency of 97%. LCD display and LED indicator for displaying operation information, customizable parameters and error codes.
It is built-in lithium-ion battery activation function to active the sleep lithium batteries. It protects against reverse polarity, overcharging, over-discharging, overload, short-circuit, etc. Ideal for DC-coupled energy storage applications.
