Do you want to generate maximum power from your Solar? Then the initial step is to make your solar smarter. Constructing automation usually has been the automatic integrated control of a building’s heating system, air conditioning, freshening and lighting systems. While this gives enhanced comfort and convenience, low O&M charges, and reduced energy consumption, it is a limited approach.
As solar energy is reaching better grid diffusion and the cost of batteries falls, smart power storage and management are more heavily donating to proceeding constructing automation. When mixing smart energy management and energy storage into a building’s automation procedure, the level of energy independence rises dramatically. To achieve this, it is significant to recognize the essential mechanisms and how they interact.
To syndicate energy sources in an insightful and intelligent manner for storage and making automation purposes, power electronics are required for two essential administrative functions. The first is to convert energy from different sources, for instance, from solar panels, battery, and grid, and then allocate the energy according to different uses and needs (consumption, storage, grid feed-in).
Another main function is to deliver full visibility into manufacture, consumption, and storage status and their individual wants in order to correctly assign power in real time. As the brain of the solar energy system, the inverter is the only component that has all of this info and already holds most of the essential electric hardware.
In terms of the battery, high-voltage DC batteries are seen as the most efficient and cost-effective way to integrate batteries into a PV system. While the quality of the actual battery is important, it is the inverter that is responsible for its functionality. For instance, you can buy a top-of-the-line guitar, but if you don’t have a knowledgeable musician to play it, then it simply becomes decoration.
To properly function with batteries, inverters need to know how to read and control batteries. This comprises having the ability to charge and release the battery according to the set profile and monitor its system status. Inverters that offer backup also need to have the ability to operate without the grid.
A power inverter is also responsible for raising system productivity, ease of design and installation, and safety. There are many key aspects of the connection between the inverter, PV system, and battery that are very significant. For instance, the relationship that reduces energy losses is key.
If one inverter can manage and monitor PV production, consumption, and storage, then this not only reduces CAPEX costs, but it also expands energy efficiency. The DC combined battery system means that there isn’t an additional conversion from AC to DC and back to AC, and therefore there are no needless power losses in the conversion process.
Another key relationship between the battery and the inverter is the aptitude to deliver insight into the battery status. The inverter is the gateway for all communications, such as managing and checking PV production, reading the meter, and analyzing house consumption habits. For example, system owners should be able to obtain full visibility into battery status, PV production, and self-consumption data through a single monitoring platform. Another benefit is that the monitoring platform can also allow O&M providers to perform remote care. Once a PV plus storage system is installed to expand building automation, it is conceivable to take energy management another step forward. With the inverter already in place, more smart energy management can be easily integrated into the building automation strategy.
For instance, the inverter can divert excess PV power to different devices to increase solar energy usage and further decrease electricity bills, improve energy independence, and provide automatic on-the-go device control. Device control can apply to hot water controllers, different electrical appliances, and heat pumps. For the commercial and industrial space, this smart energy can be applied to cold-storage in warehousing. The inverter can divert excess energy during times of high PV generation for the freezer to reach minimum temperatures, while during low PV generation, it will allow the maximum temperature to be reached.
There are so many chances to add smart energy management and storage into constructing automation. As technology advances, we will continue to see more opportunities to further integrate this into our lives; for example, weather and irradiance forecasting integrated into energy management systems can help ensure more efficient planning of building heating, or personalized profiles and thermostat controls that can help increase comfort without additional resources, as well as many more possibilities.
The key to applying energy systems into building management is to ensure that the systems are future-ready and can continue to change as the expertise advances. This will confirm that buildings can frequently mix new forms of automation.
