What do the numbers on a charge controller mean?
In other words, the Victron SmartSolar MPPT 100 | 30 can handle a max of 100 volts coming from the solar panels into the charge controller. The 2nd number, 30, represents the max amount of amps the controller can output going INTO THE BATTERIES.
What does the amperage of a charge controller mean?
When looking at a charge controller, there are a range of things to examine on its list of specifications or label. A PWM controller will have an amp reading for it, for example 30 amp PWM controller. This represents how many amps the controller can handle, in the case above, 30 amps.
How far should the charge controller be from the battery?
It is highly recommended that the charge controller be within one meter (approximately 3.25ft) of the battery bank and in the same room or enclosure.
Can a solar charge controller drain the battery?
A solar charge controller manages the power going into the battery bank from the solar array. It ensures that the deep cycle batteries are not overcharged during the day, and that the power doesn’t run backwards to the solar panels overnight and drain the batteries.
How does a charge controller work on a battery?
As the battery begins to discharge, it experiences a slight reduction in its output voltage. This relationship is used in the working of the charge controller. Charge controllers have built-in voltage sensing instruments (potentiometers), which sense the output voltage.
What are the parameters of a charge controller?
Below you find four key parameters that can be programmed in any charge controllers. They are: Regulation Set-Point This is the maximum set-point voltage. Any charge controller will protect the battery to reach a voltage in excess of this Voltage. At this point, it will discontinue any further battery charging.
What do you need to know about a solar charge controller?
A solar charge controller is an electronic component that controls the amount of charge entering and exiting the battery, and regulates the optimum and most efficient performance of the battery.
What kind of charge controller do I need for a 12V battery?
Hi Mark, with a 12V battery bank you would need quite a beefy MPPT regulator, as those panels would provide 65A+ of charge for your AGMs as 12V. This would mean you’d need an 80A controller, which is about as large as they make them, and expensive.
