INTEGRATION COEFFICIENT IC EDUCATING THE SUPPLY CHAIN
Let's use our Integration Coefficient IC with one of its strongest points that gives us a profound differential advantage in the supply chain: education for maximum customer satisfaction.
On Grid or Grid-tied solar systems are intended to operate parallel with an electric utility company. What does solar energy connected to the grid, On-grid, or Auto consumption mean?
Simply put, the electricity from the solar energy system is connected to the existing service panel of the building, home, or business, supplementing the power supplied by your utility company. While grid-tied solar systems use advanced technology, the principle behind how they work is simple.
During the day, solar panels convert solar energy into DC (direct current) power, which then flows to a grid-connected inverter or micro-inverter where this DC energy is converted into AC (alternating current) used by the connected load on the site.
From there, electricity flows to a circuit breaker in your site's electrical service panel (please check the diagram for a typical On-grid Grid system shown in this post) from where it flows to the load just as it does from your utility company.
If the site needs more electricity than the currently generated by the On-grid-solar system, additional electricity is drawn from the grid or "utility". On the other hand, the excess electricity generated returns to the grid and turns the electric meter "backward", of course, only if the electric utility company allows what we will later explain as Net-Metering agreements.
Using technical words: Grid-tied inverters take DC power and invert it into AC power that can be “returned” to the electric utility company's grid. The On-grid inverter must synchronize its frequency with that of the grid (50 or 60 cycles per second) using a local oscillator and limit the voltage to no more than the grid voltage. A modern high-quality grid-tied inverter has a fixed unity power factor input, which means that output voltage and current are perfectly aligned and its phase angle is within 1 degree of the AC grid. The inverter has a control system that will detect the current AC grid waveform and generate a voltage matching the grid.
On-grid inverters are also designed to quickly disconnect from the grid if it is cut off or presents values outside the normal working operation range. This is an NEC (in the USA) or an IEC (in Eurasia) requirement that ensures that, in the cases mentioned, the On-grid inverter will be turned off to prevent the energy it transfers from harming line workers who are sent to repair the power grid or to protect itself due to the appearance of dangerous voltages at its output.
