MPPT controllers operate solar panels at their Maximum Power Point improving efficiency up to 30% by adjusting input voltage to harvest the maximum power from the solar panels. It then manages this power to supply the varying voltage requirement of the battery plus load. The MPPT senses when to adjust the output that it is being sent to the battery and will shut down for a few microseconds, calculate and make relevant adjustments. The principle of MPPT is to extract the maximum possible power from a solar panel by setting the most efficient combination of voltage and current - maximum power point.
Load output will prevent the battery from becoming totally flat [which can cause damage]. A preset discharge level can be configured at which point the SmartSolar will disconnect the load preventing the battery draining further. Alternatively, the inbuilt intelligent battery management feature in the SmartSolar can be set. Known as Battery Life the feature is designed to protect and better maintain your battery by ensuring 100% recharge is regularly reached. SmartSolar attempts a daily 100% recharge. During periods of poor weather or low light conditions, it raises the disconnect voltage until successful.

MPPT: Ultra Fast Maximum Power Point Tracking: By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.

Ultra fast Maximum Power Point Tracking (MPPT):
Especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers. In the event of partial shading, the innovative BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.

HOW DO SOLAR 100/20 MPPT WORK ?
A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximises this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. SmartSolar maintains battery health, extending its life. MPPT controllers operate solar panels at their Maximum Power Point improving efficiency up to 30% by adjusting input voltage to harvest the maximum power from the solar panels. It then manages this power to supply the varying voltage requirement of the battery plus load. The MPPT senses when to adjust the output that it is being sent to the battery and will shut down for a few microseconds, calculate and make relevant adjustments. The principle of MPPT is to extract the maximum possible power from a solar panel by setting the most efficient combination of voltage and current - maximum power point.
Here are some safety tips for using a solar battery charge:
- Read the manual: Always read and understand the manufacturer’s instructions and guidelines provided in the user manual. Different solar chargers may have specific requirements and precautions.
- Choose a reputable brand: Purchase your solar battery charger from a reputable and trustworthy manufacturer to ensure it meets safety standards and is of good quality.
- Check for damage: Before use, inspect the charger and its cables for any signs of damage, such as frayed wires or broken components. Do not use a damaged charger, as it may pose safety hazards.
- Place in a safe location: Set up the solar charger in a safe and stable location. Avoid placing it near flammable materials or in areas prone to moisture or extreme temperatures.
- Use in appropriate conditions: Solar chargers work best in direct sunlight, so use them outdoors in sunny conditions whenever possible. Avoid using them in rainy or excessively cloudy weather.
- Keep away from water; Solar panels and electronic components are susceptible to damage from water. Ensure the charger remains dry during operation, and do not immerse it in water or expose it to rain.
- Use compatible devices: Use the solar charger only with devices that are compatible with its voltage and current ratings. Using incompatible devices may damage the charger or the device being charged.
- Avoid overcharging: Some solar chargers come with built-in protection against overcharging, but it’s still essential to monitor the charging process. If your charger does not have overcharge protection, avoid leaving devices connected for extended periods once they are fully charged.
- Do not disassemble: Never attempt to disassemble the solar charger, as it may expose you to dangerous electrical components and void the warranty.
- Store properly: when not in use, store the solar charger in a safe and dry place away from direct sunlight and extreme temperatures.
- Disconnect when not in use: Unplug and disconnect the charger from the device and the solar panel when not in use. This prevents unintended electrical connections and reduces the risk of damage.
- Educate children: If you have solar chargers accessible to children, educate them about the potential risks and how to use them safely.
By following these safety tips, you can enjoy the benefits of a solar battery charger while minimizing potential hazards and ensuring its longevity.
