What is a solar charge controller?

A charge controller is an electronic device that monitors and controls the amount of power – current and voltage –going to the battery from a solar panel. It’s an essential part of most solar systems. Without a solar charge controller, your batteries would get damaged and wouldn’t last long because of too much or too little power.

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

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.

What is a PWM solar charge controller?

PWM solar charge controllers are great for small systems where efficiency is not essential. They are common in RV, boat, and camping solar systems. They do a great job protecting the battery but they ‘waste’ some power. A 12V solar panel will typically output 16V-18V of power depending on the weather.

How much power does a solar charger controller use?

The solar charger controller itself is rated at 30amps and 100V, making it ideal or small and medium-size systems. 1. Remote Smartphone Monitoring Instead of trying to squint at a tiny display with small numbers, you can use your smartphone to monitor your battery and check the power flow.

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.
