GRANKIA CME waterproof 12v 24v mppt solar charge controller 30a-60a tracks the maximum power point of the solar panel exactly and quickly in any condition.
Innovative MPPT technology with high tracking efficiency up to 99% and peak conversion efficiency of 97%. Touch LCD screen and LED indicators for displaying system operation information, customizable parameters, and error codes.
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 mppt solar charge controller is the intelligent, cost-effective choice for low-power applications that require maximum charging efficiency. It can accept max PV INPUT 100Vdc and work with the solar panels which are designed for on-grid applications.
