GRANKIA CMR best pv 12v 24v 36v 48v mppt solar controller 30a-100a adopts advanced DSP digital control technology, it is the intelligent, cost-effective choice for low-power applications that require maximum charging efficiency. 12V/24V/36V/48V system automatic recognition, user-friendly for different systems.
There is advanced MPPT control algorithm to minimize the maximum power point loss rate and loss time, and can quickly track to the maximum power point of the photovoltaic array in any environment to obtain the maximum energy.
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.
CMR series mppt solar controller is an advanced maximum power point tracking solar controller for large off-grid photovoltaic(PV) systems. Glass panel with multi-function touch screen, the users can easy to read and set parameters.
This mppt solar controller has been proven in solar installations around the globe and remain the first choice for designers of mission-critical system where failure is not an option. It features dual RS-485 communication protocol allowing for easy programming, control, remote monitoring.
