Solar Power Storage & Monitoring System
This technology is mainly used in solar power generation systems and can be expanded for use in other renewable energy systems. Through this technology, the DC power generated by the solar panel can be converted into an AC power source or other DC ratings and connected in parallel to the utility system to provide a load.
The core technology completes the parallel current sharing control technology of the converter, which can be achieved according to the power required by the client. The Monitoring & Control system is integrated to provide a total solution for many applications, such as aquaculture & water treatment.
The long-distance communication module (7-10 km wireless transmission distance) is employed to make it smarter.
MPPT technology of PV
MPPT is a technique used commonly with wind turbines and photovoltaic (PV) solar systems to maximize power extraction under all conditions. As the amount of sunlight varies, the load characteristic that gives the highest power transfer efficiency changes, so that the efficiency of the system is optimized when the load characteristic changes to keep the power transfer at highest efficiency. This load characteristic is called the maximum power point (MPP) and MPPT is the process of finding this point and keeping the load characteristic there. A power converter can be designed to present arbitrary loads to the photovoltaic cells and then convert the voltage, current, or frequency to suit other devices or systems, and MPPT solves the problem of choosing the best pump power consumption as the system load to be presented to the cells in order to get the most usable power out.
Microbubbles are bubbles smaller than one hundredth of a millimeter in diameter, but larger than one micrometer. They have widespread application in industry, life science, and medicine. The composition of the bubble shell and filling material determine important design features such as buoyancy, crush strength, thermal conductivity, and acoustic properties. By injecting the microbubble into an area (such as fish farm), the Dissolved Oxygen (DO) can be improved and it could enhance fish and water quality.
Dissolved Oxygen (DO) is the amount of oxygen dissolved in a unit of water. Oxygen gets into water by diffusing within the surrounding air, aeration (turbulent movement), and as a waste product from plants through photosynthesis. PH indicates acidity or alkalinity of the water. By implementing galvanic and optical principle, the DO value can be measured. Whereas, by considering the activity of the hydrogen ions in the solutions, the PH value can be measured. Therefore, the DO+PH measurement result can be sensed, monitored, and controlled by integrating them with automation system.
The Internet of things (IoT) enables the extension of Internet connectivity into water quality and solar power measurement system. Embedded with electronics, Internet connectivity, and an arrangement of DO & PH sensors, these devices can communicate and interact with others over SMS, local network, and Internet communication, and they can be remotely monitored and controlled.
