6 FAQs about [How to choose between 12v and 24v solar charge controller]

Should I use a 12V or 24V solar charge controller?

When it comes to choosing between a 12V and 24V solar setup, using a 24V system requires a smaller solar charge controller compared to a 12V system. However, a 12V system needs a higher amperage load controller, which increases the price. You can save 84% by opting for a 24V system. Inverters convert the power from your batteries from 12V to 110V to work with wall outlets.

How many volts does a solar charge controller have?

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.

Why should you use a solar charge controller?

Using a solar charge controller in a 24V solar power setup is important because it regulates the voltage, protecting the battery. Compared to a 12V setup, you can get away with half the size of the solar charge controller in a 24V system. However, a 12V setup requires a higher amperage load controller, which drives up the price. You save 84% when using a 24V system.

How much wire should a solar controller use?

On a 24V system (41.7 amps), a 50 amp wire is recommended (6 Gauge AWG). When the battery bank is nearly full, the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off. By being able to regulate the voltage, the solar controller protects the battery.

How do I choose a solar charge controller?

This is where we recommend choosing a charge controller that can exceed the amp rating of your solar array, as it can spike. A good practice is to exceed the amp rating by 25%, which means multiplying the amp rating of your solar panels by 1.25 and finding a charge controller with an amp rating that exceeds that number.

Should a solar charge controller be connected directly to a battery?

• Certain low-voltage appliances must be connected directly to the battery. • The charge controller should always be mounted close to the battery since precise measurement of the battery voltage is an important part of the functions of a solar charge controller.
