Inverter for grid-tied solar panel Three-phase grid-tie inverter for large solar panel systems. A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, normally 120 V RMS at 60 Hz or 240 V RMS at 50 Hz. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric. Step 6: Synchronising Phase and Frequency. Synchronising to the mains phase and frequency is what makes a grid tie inverter. We use a digital implementation of a PLL (Phase Locked Loop) to achieve accurate phase tracking of the mains signal. We do this by:

While connecting the TR2 output with the grid, connect a 100 watt bulb in series with one of the wires. If the bulb glows, means the ACs are out of phase, reverse the connections immediately and now the bulb should stop glowing ensuring proper synchronization of the ACs. You would also want to see this simplified Grid tie circuit design. The schematic diagram of the grid-tied three-phase inverter is depicted in Fig. 27.1. The main objective of such a system is to regulate the active power extracted from the PV panel while maintaining the reactive power equal to a specified level [5].

Rated nominal/max input voltage at 800V/1,000VDC. Max 10kW/10KVA output power at 400VAC 50/60Hz grid-tie connection. Operating power factor range from 0.7lag to 0.7lead. High voltage (1,200V) SiCMosFET based full bridge inverter for peak efficiency of 99%. Less than 2% output current THD at full load. The grid-tie inverter ensures that the AC electricity generated by the renewable energy source is synchronized with the grid's AC electricity, making it possible for the electricity to be used directly or sold back to the grid. There are two main types of grid-tie inverters: string inverters and microinverters.
