A Solar Charge Controller is a device which limits the rate at which electric current produced by solar panels is added to electric batteries. Solar Charge Controller is the heart of your solar system. It keeps your batteries charged and maintains the health of your solar panels.
Solar charge controllers are used to maintaining the proper charging voltage on the batteries. As the input voltage from the solar array rises, the charge controller regulates the charge to the batteries preventing any overcharging.
Since the brighter the sunlight, the more voltage the solar cells produce, the excessive voltage could damage the batteries. A charge controller is used to maintain the proper charging voltage on the batteries. As the input voltage from the solar array rises, the charge controller regulates the charge to the batteries preventing any overcharging.
The solar charge controller is the brain of your solar power system. It installs between your solar panel array and your batteries, where it automatically maintains the charge on the batteries using a 3-stage charge cycle. This cycle ensures that the batteries are always fully charged, yet never overcharged.
Your solar energy system has four major components.
- 1. Solar Panels collect the sun’s energy and convert it into DC power.
- 2. Charge Controller is installed between the Solar Panel array and the Batteries where it automatically maintains the charge on the batteries using the 3-stage charge cycle just described. The Power Inverter can also charge the batteries if it is connected to the AC utility grid or — in the case of a stand-alone system — your own AC Generator
- 3. Batteries store this DC power until it is needed to run your appliances and lights.
- 4. Inverter, the inverter is the heart of your solar array. It converts the DC power from your panels into AC power that matches your home’s needs. When paired with solar panels and batteries, it can turn the sun’s energy into clean, renewable electricity for your home!
Can solar panel be connected directly to battery?.
- No, you can’t connect a solar panel directly to a battery. You need a solar charge controller to protect against over-charging.
What is MPPT charge controller?
- MPPT stands for Maximum Power Point Tracking. This means that the charge controller can track the maximum power point of the solar panels and battery, and adjust itself to meet that point. So it’s a lot more efficient than a non-MPPT charge controller, which will always be set to whatever voltage your battery can take (which might not be at its maximum).
- The MPPT solar charge controller is a device that can be used to improve the efficiency of your solar panels.
- Maximum Power Point Tracking uses MPPT technology to transform your solar panel system into a more efficient device.
