For many people who are fond of alternative energy such as installing solar cells, only using ready-made equipment for controlling the power supply or charging “just connect the wires to the hanger and it’s over”.
Note : sumitrapower.com The company was established to support the use of alternative energy that is environmentally friendly by generating electricity from solar cells using new technologies. “Micro Inverter System” If you are interested in the product. or want to find more information Please visit us
But if you try to get a microcontroller board like Arduino Control basic systems such as power supply control systems. It will be able to open up new experiences. To be able to extend to larger projects
Whether it’s an inverter or a micro inverter or a battery charging controller that the solar cell industry is very familiar with. Each must have a microcontroller to control the operation of the device. So if we try to use a developer microcontroller like Arduino, our solar cell system will not just be a power supply system, but the Arduino solar cell will definitely be a big project for us in the future.
Then I would like to present a prototype solar cell system project that controls the use of electricity supply to the load. The power supply of the solar cell system and (2) the transformer This system uses an Arduino to control the distribution of electricity between the battery that stores power from the solar cell transformer. (Telephone charger cable) that receives AC 220V AC power from general household sockets. This indicates that the load under the Arduino system power will never be stopped. (There is electricity for 24 hours a day), which this project is suitable for activities that require continuous use of electrical power automatically without human hands to control, such as lighting systems, water supply systems, etc., and such systems can still maintain the problem. The key is Energy savings are complementary!
Arduino Solar Hybrid Project
Arduino Solar Hybrid is a power supply control system that complements a battery that receives electricity from sunlight (solar cells) and a transformer. (phone charger that gets power from AC 220V power supply. The device used to control both power supply is Arduino, a microcontroller board for program developers.
Solar energy produced from solar panels will be the main source of electricity When electricity from the sun If the power supply (battery power) has weakened, or if the continued power supply is dangerous to the supply, the Arduino will immediately switch the supply to the transformer. Until the solar battery is ready to supply power again, the Arduino will switch back to battery power.
project objectives
Of course, the purpose of the solar cell installation project is Guidelines for saving electricity By using electricity produced from non-consumable materials or materials that are not exhausted. The scorching sun produces heat and light for 6-8 hours a day, a naturally occurring but inexhaustible energy. Therefore, if this natural phenomenon is taken to convert into electrical energy use It will be able to save the main electricity generated from consumables immediately.
The Arduino Solar Hybrid project is designed for powering the load. or appliances that must work continuously Or have to work 24 hours a day, which if we use only one main power supply from the electricity supply can be costly Then if we use electrical power from other sources that can be produced by itself from something that exists naturally like sunlight Supporting the use of electricity in this project It will help us to save more than half of the electricity bill that we pay regularly.
Why did the project name Arduino Solar Hybrid help each other? Electrical energy from the process of converting energy from solar cells. Electricity can be charged to the battery for a limited time, such as 6-7 hours during the day. So during this time the load can be fully powered and cost-free (economical and if we choose to use lithium ion batteries (same batteries as mobile phones) it will be very suitable for this project. Because lithium-ion batteries have outstanding features in charging electricity, for example mobile phone We can plug in and charge our mobile phones without limitation. Even if the phone battery is not depleted, for example, the battery is 55% or 68%, we can charge the battery to 85% or 90% and then remove it from charging. And if we charge the phone like this all day or all week or forever, charging the phone battery like this. It does not cause the phone battery to deteriorate. But it will help the battery life to its full potential. But if we use the phone until the battery runs out (power off) or leave it plugged in to charge all night without turning it off. This type of use is the main reason for the rapid deterioration of lithium-ion batteries.
So why compare phone charging? because the load uses electricity from solar cells during the day Will cause electricity to be charged into the battery all the time and not at all 100% during that time, for example, the lamp uses 10% of the battery power in 20 minutes and in this 20 minutes, the controller will charge. The electric charge was added all the time for 20 minutes, charging at 7% or 8%, but the lantern used 10%, so the battery was not fully charged to 100% (climbed to 80-90 levels throughout the day), which was considered a use. Li-ion batteries work accurately and with the most efficiency. When the light from the sun is gone Electric charge from the solar panel will not occur. But the load must continue to work according to the project’s purpose, so the electric power from the battery will gradually decrease. Until the level where the battery should stop supplying power (20% remaining), the Arduino system will order to switch to the transformer immediately. Until the battery receives a charge of more than 80%, Arduino has ordered to switch to use the battery from the solar panel as before.
and working principle of Arduino Solar Hy project This brid can be applied to the power supply in the alternating current system AC 220V.
