How Many Amps For Solar Charge Controller. However due to environmental factors you need to factor in an additional 25 bringing the minimum amps that this charger controller must have to 175 amps. If your solar systems volts were 12 and your amps were 14 you would need a solar charge controller that had at least 14 amps.
That multiple may be. A 100W solar panel with a 12V battery bank needs a 10 amp charge controller. Amperage ratings can be between 1-60 amps and voltage ratings from 6-60 volts.
We still want to adjust this value by 25 to take into account any special conditions that might cause the solar module array to produce more power than it is normally rated for eg.
The most common pv charge controllers come in 12 24 and 48 volts.
