Customer ServiceCharge controllers keep your batteries from being overcharged by limiting the volume and charge intensity of them. They often avoid the battery from being depleted by shutting down the device if the storage power dropped below 50 percent capacity. The batteries are getting charged at the right voltage level.
Customer ServiceIf your solar array is bigger than the current output of the charge controller it will limit it''s output. For example, a 500W solar array has a charging current to the battery of 41.6A (500W/12V=41.6A) you can use a 30A charge controller without damaging it. You will damage a solar charge controller if you go over the maximum input voltage.

Customer ServiceSelecting the Right Size Controller To size a solar charge controller, take the total watts of your solar array and divide it by the voltage of your battery bank, then multiply by a safety factor of 1.25. This calculation will give you the output current of the charge controller.
Typically, the size of the solar charge controller is calculated by taking the solar panels’ total wattage and dividing it by your battery bank’s voltage. This will give you the minimum amps your controller needs, and it’s often recommended to get a controller with a higher capacity to handle potential increases in power.
Charge controllers are rated according to amperage. Charge controllers are sized to cope with the input voltage and current from the solar panels and how this power is most efficiently transferred to the battery bank. A safety factor of 25% is added to the solar array amperage to compensate for environmental factors.
Only DC loads can connect to the output of the charge controller. You should mount the charge controller next to the battery as the battery voltage’s accurate calculation is an essential aspect of the solar charge controller’s functions. Conclusion
Typically, charge controllers come in 12, 24 and 48 volts. Amperage ratings can be between one and 60 amps and voltage ratings from six to 60 volts. If you haven’t sized your system yet or calculated your energy needs, we recommend using the Renogy solar power calculator.
If your solar system was 12 volts and your amps were 14, you will need a solar charge controller with at least 14 amps. However, you need to add 25% to the minimum amps that your solar charger controller would have at 17.5 amps due to environmental considerations.
