Why Is The Solar Micro Inverter
- The transition from a centralized to a distributed solar micro inverter optimizes energy collection.
- The converter module integrated into the solar panels can reduce installation costs.
- Soft switch technology to replace hard-switching technology can improve efficiency and reduce heat dissipation.
- From cottage industry to mass production, standardized design (hardware and software) to improve reliability and reduce costs.
- Using a special capacitor (due to the high failure rate). Design requires a higher voltage to reduce the current, we use a special electrolytic capacitors.
- The converter can be connected to the grid to eliminate the need for many battery applications.The high price of batteries, require maintenance, life expectancy is shorter.
- Work required solar micro-inverter power increasingly smaller (only a few hundred watts), which can reduce the internal temperature and improve reliability.
- Solar micro-inverter system needs to deal with a lot of a particular power level, in order to increase production, thereby reducing costs.
