System Block Diagram & Application 


In order to achieve higher power, we can use this inverters in stack. For example: 10 pcs of SPWVC1200 1200W grid tie inverters used in stack can achieve 12KW. And the stacking number is unlimited.


Easy Installation



Single-phase & 3 Phase electrical schematics



1. Please install the inverters according to the user manual and connect the ground safety.

2. Forbid openning the shell with non-professional person ,only qualified maintenance person can repair the product .

3. The inverter should be installed in the low humidity and well ventilated place,and remove the flammable things surrounding the inverter for avoiding overheating .

4. Avoid children play when the inverter is working.

5. Ensure the DC input and AC output when connect with PV.

6. The Vmp and Voc of PV should be fit for the Inverter MPPT input voltage for get output max.


 Why is the use of micro-inverter?


  1. The transition from a centralized to a distributed inverter optimizes energy collection.
  2. The converter module integrated into the solar panels can reduce installation costs.
  3. By reducing the temperature of the converter and remove the fan, you can enhance system reliability from 5 years to 20 years.
  4. Soft switch technology to replace hard-switching technology can improve efficiency and reduce heat dissipation.
  5. From cottage industry to mass production, standardized design (hardware and software) to improve reliability and reduce costs.
  6. 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.
  7. 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.
  8. Work required micro-inverter power increasingly smaller (only a few hundred watts), which can reduce the internal temperature and improve reliability.
  9. Micro-inverter solar inverter system needs to deal with a lot of a particular power level, in order to increase production, thereby reducing costs.
