Basic System Composition and Operating Principle: (Grid-connected Solar Power System without Batteries) The Wenbo Home Distributed Grid-connected Solar Power System mainly consists of photovoltaic modules and their mounting structures, grid-connected inverters, AC distribution boxes, monitoring systems (local monitoring is standard; remote and environmental monitoring are optional), and connecting cables. On sunny days, the DC power generated by the photovoltaic modules installed on the roofs of residential areas or villas is converted by the grid-connected inverter into single-phase AC power with the same frequency and phase as the grid to supply the load. During periods of insufficient sunlight, such as at night or on cloudy or rainy days, the system enters standby mode, and all load power is drawn from the grid. You can use the standard local monitoring software to view the system's operating status and fault information in real time. Alternatively, by opting for the remote communication data collector, you can transmit your power station's data via GPRS or Ethernet to your mobile phone, tablet, or any internet-connected computer, allowing you to remotely monitor the station's information in real time. Main Features of the System: One-stop turnkey service: We tailor a dedicated power station for you based on your actual situation and needs. The selected equipment and materials are of reliable quality and low cost, ensuring your power station offers excellent value for money. The use of grid-connected inverters with isolation transformers achieves electrical isolation between the DC and AC sides, providing strong protection for the grid and your personal safety. Multiple monitoring options are available, with innovative application of IoT technology in photovoltaic remote monitoring, enabling you to access station information anytime, anywhere via handheld devices (such as mobile phones or tablets) or any internet-connected computer. Home distributed grid-connected photovoltaic power stations offer advantages such as being green, pollution-free, local consumption, and low losses, making them a "low-risk, stable-return, long-term" investment. Flexible grid-connection methods: You can choose any of the three grid-connection modes—"self-generation and self-consumption, surplus electricity fed into the grid, or full grid feed-in"—based on your actual situation. Regardless of the mode chosen, you can enjoy financial subsidies from the national and local governments. The grid-connection process is simple. Home distributed grid-connected photovoltaic power stations are a form of new energy power generation vigorously promoted during the National 12th Five-Year Plan. Currently, the National Development and Reform Commission, State Grid Corporation, and local governments such as Jiaxing, Hefei, Tongxiang, and Jiangxi have successively introduced support, subsidy, and service policies.
