What is the prospect of grid-connected inverter?

WVC 1200 adopts IP65 waterproof streamline design, which can effectively prevent rain from eroding the surface, and has built-in high-performance maximum power point tracking function, which can better track the change of solar luminosity, control different output powers, and effectively capture and collect sunlight. Power transmission adopts reverse AC power transmission technology, which is one of our patented technologies. The power output by the inverter can be given priority to the load, and the inexhaustible power can be reversely transmitted to the power grid, so that the power generated by the inverter can be used efficiently, and the power transmission rate can reach over 99%. There are two communication modes. The inverter communicates with the collector through power line carrier signal, and the collector communicates with PC or other devices through RS232 serial port /WIFI wireless mode. The intelligent monitoring system can collect the real-time data of the frequency converter and control the startup/shutdown/power adjustment function of the frequency converter. ? Why use a micro inverter? Changing from centralized inverter to distributed inverter optimizes energy collection. Integrating the converter into the solar panel module can reduce the installation cost. By reducing the converter temperature and removing the fan, the system reliability can be improved from 5 years to 20 years. Using soft switching technology instead of hard switching technology can improve efficiency and reduce heat dissipation. From shanzhai to mass production, standardized design (hardware and software) can improve reliability and reduce costs. Use special capacitors (due to high failure rate). The design needs a higher voltage to reduce the current, and we use a special electrolytic capacitor. Connecting the converter to the power grid can eliminate the need for batteries in many applications. Batteries are expensive, need maintenance and have a short life. Micro inverter needs less and less power (only a few hundred watts), which can reduce the internal temperature and improve the reliability. Micro-inverter solar system needs many inverters to handle a specific power level, so as to increase output and reduce costs. ? Characteristics of Photovoltaic Micro-inverter Intelligent monitoring and management of high-performance automatic power point tracking (MPPT) reverse power transmission Input and output are completely isolated to ensure safe and reliable power consumption. All-digital control of multiple parallel stacks simplifies maintenance (user's own maintenance). Low operation and maintenance cost and flexible installation? WVC 1200 parameter table?
