What is a solar charge controller?

A solar charge controller is an essential element in any solar-powered system, whether it be a home or an RV. This gadget regulates the power flow between the solar panel and the battery, ensuring that the battery remains at a consistent state of charge.

What batteries can a solar charge controller charge?

The solar charge controller is compatible with batteries ranging between 12V and 48V, another reason why it’s the best for large systems with large batteries. It can charge four types of batteries: Gel, Flooded, Sealed, and User-defined (you can set your battery parameters. Ideal if you have a lithium-ion battery). 4. Easy to Use LCD display

Which solar charge controller is best?

Best Bluetooth-Connected Solar Charge Controller: SmartSolar MPPT 100V 30A Charge Controller If you’d like to check your battery or power flow status without having to look at the display on the charge controller or a connected meter, we recommend the SmartSolar Bluetooth-connected MPPT charge controller.

How does a solar charger work?

The solar charger converts light energy from the sun into 12 volt DC electricity which is then transported to the rechargeable batteries through lead wire and connector of choice, replace the self-discharge of a battery in storage, so that the battery wouldn't "go dead".

Do you need a solar charge controller?

Not everyone using solar panels needs a charge controller. Generally, a charge controller is essential in situations involving a significant amount of current, which could overcharge or damage the battery. But if you are using small solar panels that output a limited amount of current and voltage, you likely don’t need a solar charge controller.

Can a 12V solar panel charge a battery?

A 12V solar panel will typically output 16V-18V of power depending on the weather. But to charge a 12V battery, the charge controller has to step down that voltage to match that of the battery. If you want to capture this lost power, get an MPPT controller.
