The charge process is performed in a smart or intelligent way.
Do you need a regulator for a solar panel.
Put simply solar voltage regulators do this by basically disconnecting the solar panels from the battery.
Choosing the right solar charge controller regulator.
The panels need to provide some extra voltage so that when the sun is low in the sky or you have heavy haze cloud cover or high temperatures you still get some output from the panel.
The solar charge regulator features three led indicators high voltage low voltage charging and three connections for the solar panel keyed two pin connector battery keyed two pin connector and 12v output 3 in.
Selecting a solar regulator.
A fully charged 12 volt battery is around 12 7 volts at rest around 13 6 to 14 4 under charge so the panel has to put out at least that much under worst.
If we were to look at the job description of any solar regulator the first item and in some cases the only function is to prevent the battery bank from being over charged.
Why do you need a solar charge controller.
If you have a five watt panel in the above example you take 100 divided by 3 300ma and you come up with 333 3.
In conclusion a solar panel regulator is just a switch that regulates the current and voltage coming going into the battery from the solar panel.
See all solar charge controllers.
This solar charge regulator protects and regulates the charge of a 12 volt storage battery using solar panels.
Since this is larger than 200 you do not need a charge controller.
However you still need a blocking diode to prevent the battery from discharging to the panel at night.
This means that a 1 5a panel is the largest you should use without a regulator on a 100 amp hour battery.
As a general rule panels that produce less than 1 5 of a battery s rated capacity in amp hours don t require regulation.
Do you need a charge controller.
This involves varying charge stages voltages and current depending on the type of battery and other factors.
So what does a regulator do.
A solar charge controller frequently called regulator is similar to a regular battery charger i e.
The regulator does this by simply disconnecting the solar panels from the battery.
Why do we need a solar regulator.
A solar charge controller is designed to receive power from a solar panel or array of panels and use it to charge a battery or bank of batteries.
To determine the size regulator you ll require check the amp ratings of your solar panels and add those figures up and that will give you the minimum size charge controller you ll need or you can use our system builder tool which will tell you the size you ll need based on various selections.
