Why Is The Solar Micro Inverter

1. The transition from a centralized to a distributed solar micro inverter optimizes energy collection.
2. The converter module integrated into the solar panels can reduce installation costs.
3. Soft switch technology to replace hard-switching technology can improve efficiency and reduce heat dissipation.
4. From cottage industry to mass production, standardized design (hardware and software) to improve reliability and reduce costs.
5. 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.
6. 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.
7. Work required solar micro-inverter power increasingly smaller (only a few hundred watts), which can reduce the internal temperature and improve reliability.
8. Solar micro-inverter system needs to deal with a lot of a particular power level, in order to increase production, thereby reducing costs.
