Principle of Operation  SYSTEM  PIN  SOLAR  grid  SolarCity 40 KWP 3 PHASE

– The electricity obtained from the battery panel (Solar Panel) is DC, via the grid tie (Grid Tie Inverter), with the function of converting DC – AC electricity in the same phase with the same frequency as the grid, then the system will be In conjunction with the grid:

+ When the grid capacity is equal to the load capacity, the load consumes completely electricity from solar cells.

+ When the load capacity is larger than the grid capacity, the load will get additional grid.

+ When the load capacity is less than the grid capacity, electricity from the grid will be returned to the grid. (Do not charge money when the balance is over because EVN has not yet turned the clock back.

When designing grid system (until now), design such that grid capacity ≤ consumption power consumption)

– SolarCity grid system works automatically, disconnects when it is dark or when there is no power grid to ensure the most economical and safest. (Advantages of the system: Efficiency reaches over 97% .. do not use batteries should not require any maintenance)

Grid  system is open system, system capacity does not depend on the load capacity used.

For example: An office with a capacity of 10KW / h. Use from 8 am – 4 pm. Total electricity used is: P = 10 * 8 = 80KW:

– If the office invests in a 10KW grid system, the amount of electricity connected to the grid per day is about 40KW, counting 8 hours of sunshine (depending on sunny conditions in each region). The amount of electricity saved about: 40/80 = 50% of power consumption

– If the office invests in a 20KW grid system (maximum), then the amount of electricity connected to the grid is about 80KW / day (average in Vietnam 1 day 8h peak sunshine). The amount of electricity saved in a day is about: 80/80 = 100% of the electricity consumed.
