Hi,
For a university project we have to build a solar inverter. A solar panel will be supplied to us, and the challenge is to design a circuit which converts the output of the solar panel to 20VAC which can then be fed into a 20VAC (not 220VAC because of safety) power grid. The main issue we are facing is the synchronization with the grid. We know that the frequency and phase of the power must be equal to the frequency and phase of the power grid, but what is the easiest way to synchronize a solar panel system with the grid? The only possible method we have found so far is the so called 'dark lamps method', but we have been unable to obtain a schematic and explanation for this method.
Thanks in advance
