DESC:TECHNICAL FIELD
[0001] The present disclosure relates to the field of DSP sinewave inverter and, more particularly relates to managing and controlling functions of solar integrated inverter automatically as well as remotely using a central server.
BACKGROUND
[0002] Traditional inverter systems have been utilized for converting DC power from sources such as solar panels into AC power suitable for powering electrical appliances. However, several challenges have been encountered in conventional inverter designs. One notable issue is the limited capability of traditional inverter systems to efficiently manage power distribution and charging during prolonged power outages. This limitation often results in inadequate power supply to electrical appliances, particularly when heavy loads are involved, leading to inconvenience and potential disruptions in user operations.
[0003] Furthermore, conventional inverter systems typically rely on a single power source, such as the main grid or solar panels, for charging the inverter battery. This dependency on a single power source poses challenges in scenarios where the availability of one power source is compromised, such as during extended periods of mains power outages or reduced solar panel output due to environmental factors.
[0004] Additionally, traditional inverter systems often lack robust monitoring and control capabilities, limiting user oversight and intervention in system operations. Without comprehensive monitoring features and remote-control functionality, users may face difficulties in optimizing energy utilization and addressing system malfunctions promptly.
[0005] These shortcomings in traditional inverter designs underscore the need for innovative solutions capable of addressing the aforementioned challenges and enhancing the efficiency, reliability, and user-friendliness of solar integrated inverter systems.

[0015] Fig. 1 illustrates a system 100 for managing a solar integrated DSP sinewave inverter system. In an example embodiment, the system 100 may include an inverter 102. The inverter 102 is configured to convert DC power from solar panels into AC power for supplying to electrical appliances. For instance, during daylight hours, the inverter 102 receives DC power generated by solar panels and converts it into AC power, allowing connected appliances to operate efficiently using renewable energy sources.
[0016] The system 100 further comprises a charge controller 104 connected to the solar panels. The charge controller 104, which is a MPPT charge controller in this embodiment, regulates the power supply to the inverter 102. For example, the charge controller 104 optimizes the voltage and current from the solar panels to maximize power transfer to the inverter 102, thereby enhancing the overall efficiency of the system.
[0017] Additionally, the system 100 includes a display screen 106 positioned on the inverter 102. The display screen 106 provides real-time feedback by displaying parameters such as battery charge status and connected appliance power consumption. For instance, the display screen 106 may show the current battery charge level and the amount of power being consumed by each connected appliance, allowing users to monitor energy usage.
[0018] Moreover, a memory unit 108 is incorporated into the system 100, storing predefined instructions related to inverter functions. The memory unit 108 enables the system to operate according to specific user preferences and predefined settings. For example, the memory unit 108 stores instructions for prioritizing solar panel charging during daylight hours and mains power charging during nighttime.
[0019] Furthermore, the system 100 features a communication unit 110 configured to support remote communication. The communication unit 110 facilitates remote monitoring and notification of maintenance requirements. For instance, users can receive alerts on their mobile phones via the communication unit 110 regarding system performance or the need for maintenance.
[0020] An integral component of the system 100 is the control unit 112, configured to manage inverter functions based on the predefined instructions stored in the memory unit 108. The control unit 112 automatically controls charging of the inverter from available sources, adjusts power supplied by each source to charge the inverter battery, and switches on the inverter to supply power to the load under overload conditions. For example, the control unit 112 may prioritize solar panel charging when mains power is unavailable or adjust power distribution during peak demand periods.
[0021] In an illustrative scenario, consider a situation where mains power becomes unavailable due to a grid outage. In this instance, the control unit 112, utilizing the predefined instructions stored in the memory unit 108, automatically switches the charging source to solar panels. By prioritizing solar panel charging, the control unit 112 ensures uninterrupted power supply to the load, utilizing renewable energy sources during the grid outage.
[0022] Furthermore, during periods of high energy demand, such as evenings when household appliances are in use, the control unit 112 dynamically adjusts power distribution to optimize inverter performance. For instance, if the load demand exceeds the capacity of the solar panels, the control unit 112 may increase reliance on mains power to supplement energy requirements, thus ensuring consistent power supply to the load without compromising performance.
[0023] Additionally, in the event of an overload condition where the demand from the load exceeds the inverter's capacity, the control unit 112 takes proactive measures to maintain power supply stability. For instance, if the load suddenly increases beyond the inverter's capability, the control unit 112 swiftly switches on the inverter to supply additional power, supplementing mains power and preventing disruptions to critical appliances.
[0024] In an example embodiment, the control unit 112 is further configured to automatically adjust the power supplied by each source based on real-time weather conditions affecting solar panel efficiency. For instance, if weather conditions result in reduced solar panel output, the control unit 112 may increase reliance on mains power to compensate.
[0025] Consider a scenario where the system 100 is installed in a location prone to frequent cloudy weather conditions. During periods of reduced sunlight due to clouds, the solar panel output may decrease, impacting the overall energy generation capability of the system. In response to this, the control unit 112, equipped with weather monitoring capabilities and utilizing the predefined instructions stored in the memory unit 108, detects the decrease in solar panel efficiency. Subsequently, the control unit 112 automatically adjusts the power distribution strategy, increasing reliance on mains power to maintain consistent energy supply to the load. By dynamically adapting to real-time weather conditions, the control unit 112 ensures uninterrupted power availability, mitigating the impact of reduced solar panel output.
[0026] Furthermore, in regions characterized by variable weather patterns, such as coastal areas experiencing frequent fog or mist, the control unit 112 plays a crucial role in optimizing energy utilization. In instances where dense fog reduces solar panel efficiency, the control unit 112 swiftly responds by reallocating power sources to mitigate the impact on energy generation. By seamlessly transitioning to alternative power sources, such as mains power, the control unit 112 ensures continuous energy supply to the load, demonstrating its capability to adapt to changing environmental conditions in real-time.
[0027] Additionally, the control unit 112 may automatically switch off the inverter during periods of low demand to conserve battery power. For example, during nighttime when energy consumption is minimal, the control unit 112 may deactivate the inverter to preserve battery charge.
[0028] In a practical scenario, consider a residential setting where energy demand significantly decreases during nighttime hours when most household appliances are turned off, and occupants are asleep. During these periods of low demand, the control unit 112, utilizing the predefined instructions stored in the memory unit 108, monitors the energy consumption patterns and detects the reduced load on the system. Recognizing the minimal energy requirements, the control unit 112 initiates an automatic shutdown sequence, deactivating the inverter to conserve battery power. By switching off the inverter during nighttime, the control unit 112 optimizes battery usage, extending its lifespan and ensuring sufficient energy reserves for future demand.
[0029] Furthermore, in commercial applications where energy usage fluctuates throughout the day based on operational activities, the control unit 112 plays a crucial role in managing energy consumption efficiently. During periods of reduced activity, such as during lunch breaks or non-operational hours, the control unit 112 employs an energy-saving strategy by automatically turning off the inverter. By proactively deactivating the inverter when energy demand is low, the control unit 112 conserves battery power, reducing overall energy costs and enhancing the system's sustainability. This adaptive approach to managing inverter operation based on demand fluctuations exemplifies the versatility and energy-saving capabilities of the control unit 112 in optimizing system performance.
[0030] In an alternate embodiment, the control unit 112 is configured to implement predictive energy management strategies based on historical data analysis. By analyzing historical energy consumption patterns stored in the memory unit 108, the control unit 112 can anticipate future energy demand trends and proactively adjust power distribution accordingly. For instance, if the control unit 112 identifies a recurring peak demand period during certain times of the day, it may preemptively allocate additional power from mains or solar sources to ensure uninterrupted supply during these periods. This predictive energy management approach enhances system efficiency by optimizing power distribution in anticipation of fluctuating energy demands, ultimately improving overall energy utilization and reducing reliance on backup power sources.
[0031] In another embodiment, the control unit 112 is equipped with machine learning algorithms for adaptive energy optimization. By continuously analyzing real-time data from sensors and feedback mechanisms, the control unit 112 can adaptively optimize power distribution strategies to dynamically changing environmental conditions and user preferences. For example, the control unit 112 may learn from user behavior patterns and adjust power distribution schedules accordingly, optimizing energy usage to align with user preferences and maximizing self-consumption of solar energy. Additionally, the control unit 112 can adaptively respond to external factors such as weather variations or changes in energy tariff rates, dynamically optimizing power allocation to minimize costs and maximize energy efficiency.
[0032] For instance, in regions where weather conditions are prone to sudden fluctuations, such as areas experiencing frequent cloud cover or intermittent rainfall, the control unit 112 employs adaptive response mechanisms to mitigate the impact on energy generation. By continuously monitoring real-time weather data through integrated sensors or external weather forecasting services, the control unit 112 can anticipate changes in solar panel efficiency and adjust power distribution accordingly. In the event of reduced solar panel output due to cloud cover, the control unit 112 may increase reliance on mains power or alternative energy sources to compensate for the temporary reduction in solar energy generation. Conversely, during periods of clear skies and optimal sunlight exposure, the control unit 112 may prioritize solar panel charging to maximize energy harvesting from renewable sources, thereby enhancing overall energy efficiency.
[0033] Moreover, the control unit 112 dynamically optimizes power allocation in response to changes in energy tariff rates imposed by utility providers or regulatory authorities. For example, during peak demand periods when energy tariff rates are higher, the control unit 112 may adjust power distribution to minimize reliance on grid power and prioritize energy consumption from renewable sources such as solar panels. By intelligently managing power allocation based on fluctuating energy tariff rates, the control unit 112 enables users to reduce electricity costs and maximize savings over time.
[0034] This adaptive energy optimization capability enhances the flexibility and responsiveness of the system 100, allowing for intelligent and efficient management of energy resources in diverse operating conditions.
[0035] The display screen 106 may also display real-time power generation from solar panels, including graphical representations of solar panel efficiency and energy production trends over time. For example, users can track solar panel performance and energy production patterns using the display screen 106.
[0036] In a residential solar energy system equipped with the system 100, homeowners can utilize the display screen 106 to monitor the performance of their solar panels in real-time. By accessing the display screen 106, users can view graphical representations depicting the efficiency of their solar panels and track energy production trends over specific time intervals, such as daily, weekly, or monthly periods. This feature enables homeowners to assess the effectiveness of their solar energy system, identify any performance issues or inefficiencies, and make informed decisions regarding system maintenance or optimization. Additionally, the display screen 106 provides valuable insights into the overall energy production patterns, allowing users to gauge the system's contribution to their energy needs and assess the environmental impact of utilizing solar power.
[0037] Furthermore, the memory unit 108 may store historical data related to inverter operations, comprising detailed logs of power consumption patterns, battery charging cycles, and fault events for diagnostic and optimization purposes. For instance, users can access historical data stored in the memory unit 108 to analyze system performance and identify areas for improvement.
[0038] In a commercial solar energy installation utilizing the system 100, facility managers can leverage the memory unit 108 to maintain comprehensive records of inverter operations. By accessing the stored historical data, facility managers can review detailed logs of power consumption patterns, providing insights into energy usage trends and peak demand periods. Additionally, the memory unit 108 archives battery charging cycles, enabling facility managers to monitor the health and performance of the battery system over time. Furthermore, in the event of fault events or system errors, the memory unit 108 records relevant data, facilitating troubleshooting and diagnostics to swiftly address any issues. By analyzing the historical data stored in the memory unit 108, facility managers can gain valuable insights into system performance, identify inefficiencies or areas for optimization, and implement targeted strategies to enhance overall energy efficiency and reliability. This comprehensive approach to data management and analysis exemplifies the functionality and versatility of the memory unit 108 in optimizing the performance of solar energy systems.
[0039] In an example, the communication unit 110 may be configured to enable remote firmware updates for the inverter. For example, users can remotely update the firmware of the inverter via the communication unit 110 to ensure the system operates with the latest features and security patches.
[0040] Consider a scenario where a residential solar energy system equipped with the system 100 is installed in a remote location with limited accessibility. In this scenario, the communication unit 110 plays a crucial role in facilitating remote firmware updates for the inverter. Using a mobile application or web-based platform, homeowners can remotely connect to the system 100 via the communication unit 110 and initiate firmware updates for the inverter. By leveraging the communication unit 110, users can seamlessly download and install the latest firmware updates, incorporating new features, performance enhancements, and security patches to ensure the optimal operation of the system. This remote firmware update capability provided by the communication unit 110 enhances the overall functionality and longevity of the solar energy system, enabling users to stay up-to-date with advancements in technology and maintain peak performance of their renewable energy infrastructure.
[0041] Overall, the aspects of the present disclosure provide a comprehensive solution for automatically charging of the inverter from solar panels. Due to low capacity of the battery of the inverter, the inverter dies out with the use of heavy load appliances in case of power outage for longer duration of time. Thus, this inverter can last for longer durations and provide uninterrupted power supply to the user when the inverter is solar connected.
