For larger capacity solar PV plants, arranging a massive land and preparation of ground is a regular challenge. Most of the times lots of elevation differences such as hillsides and hills, there may be shadows cast by peaks or high buildings. The output consistency of photovoltaic modules in these situations cannot be guaranteed and the amount of power generated will be greatly affected. Therefore, the use of Smart inverters with multiple channel advanced MPPT function is essential. For high capacity power stations such as 10MW and above, a distributed inverter solution is recommended. Since distributed inverters utilize centralized on-grid techniques, besides having a good cost efficiency, it also has higher conversion efficiency and power quality and is suitable for use in large power stations. As for smaller power stations, string-type inverters are a good solution. When using string or distributed inverter solutions, there should be a MPPT channel for every 2-4 stringed modules. When compared to central inverters with a MPPT channel for every 500kW, it is able to better track the output power of the photovoltaic panels and greatly increases the amount of power generated by the system. The outdoor distributed power generation unit uses a container solution which integrates functions such as protection, heat dissipation, fire protection , lighting, power distribution, and monitoring devices into one and is easy and convenient to install and maintain, and enables the quick delivery of power stations.
