GRANKIA CMS4024 small 40 amp mppt solar controller 12v 24v auto 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.
MPPT solar controller 12v 24v 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.
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.

MPPT Solar Controller 12V FAQ
-
What size 12V solar regulator do I need?
If you are putting your batteries together in a 12V bank, you’d need regulators for 165+ amps of current. Eg. if you are putting your batteries in a 24V bank, you’d only need 85 amps or so.
-
How does a 12V solar charge controller work?
A solar charge controller is used to keep the battery from overcharging by regulating the voltage and current coming from the solar panel to the battery. It is programmed at 15-A/200-W unit and uses MPPT (maximum power point tracking) to accelerate solar charging of the battery up to 30% per day.
-
What does solar controller do when battery is full?
The charge controller protects batteries and solar panels by managing the energy flow. Battery charge controllers stop electricity flow when they signal that batteries are full. Many solar power systems incorporate inverters and charge controllers to ensure trickle charging and redistribute excess charges.
