Cheap electric appliances

Dr. Trinh Quang Dung from the Ho Chi Minh City Institute of Physics and the research team recently completed the model of solar power system connected to grid electricity for household use.

Excess solar power will be stored in the storage system
(through the device) for redundancy at power cuts.

This is the first time this research has been successfully applied in Vietnam. The system has a solar array of 8.400Wp, providing about 15,000KWh per year. 24 hour security; Providing 100% of electricity demand in case of power failure. The solution is to design a system to harness the power from a straight-line solar array for the load, which would otherwise take power from the net.

Excess solar power will be stored in the storage system (via equipment) to provide backup power at the power cut. When the net sells cheaply, the device will start to buy the full power of the storage system (from 22:00 to 4:00 am) to use during peak hours to support the load. The whole process of this activity has been researched and designed to operate fully automatic.

Experimental results showed a very positive result in a building in Binh Tan District, Ho Chi Minh City. After more than two months of operation, the solar panel with a capacity of 8.400Wp will produce 15,118.4KWh / year, meeting 100% of the demand for electricity, 30% of the total electricity demand of the building. . According to calculations, reserve electricity capacity will reach about 62KWh / day, buying about 30KWh cheap electricity per day.
