MCR4048 40a mppt solar charge controller 12v 24v 48v for solar system
MPPT solar charge controller | 40A | 12V/24V/48V AUTO | Max PV INPUT: 170VDC
Prostar MCR4048 40a mppt solar charge controller 12v 24v 48v for solar system adopts die-cast aluminum heat sink to make heat dissipation more efficient.
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.
It protects the battery from becoming over-charged by the solar modules and over-discharged by the loads. By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage.
It is widely used in many fields such as RVs, communication base stations, household systems and field monitoring.
