MPPT Solar Charge Controller | 40A | 12V/24V(Auto) | PV Voltage: 100Vdc | IP43
GRANKIA CME4024 cheap 12v solar battery charger mppt 40a 24v is a technique to observe and regulates the energy going from solar panel to the batteries.
Solar panels show changeable outputs according to weather conditions. MPPT charge control devices can match the solar panel voltage with battery voltage to maximize the charge efficiency.
MPPT 12v solar battery charger can be up to 30% more efficient, depending on the battery voltage and operating voltage (Vmp) of the solar panel.
The main difference between PWM and MPPT charge control devices is that the MPPT devices are more efficient. MPPT charge control devices have 30 % more efficient in charge efficiency according to PWM type.
20W and 50W solar panels are good for fast charging small 12V batteries. For example, a 20W solar panel can charge a 20Ah 12V battery in around 17 hours of direct sunlight. A 50W panel can do it in around 8 hours. 80W and 100W solar panels are good for fast charging large 12V and car batteries.
You need around 610 watts of solar panels to charge a 12V 200Ah lithium battery from 100% depth of discharge in 5 peak sun hours with an MPPT charge controller.
