Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
Grid connected PV systems always have a connection to the public electricity grid via a suitable inverter because a photovoltaic panel or array (multiple PV panels) only deliver DC power. As well as the solar panels, the additional components that make up a grid connected PV system compared to a stand alone PV system are:
It is important to mention that the system is always connected to the grid but the grid supplies in parallel with the inverter/solar panels the energy demand of the household. Inverter and grid run in parallel feeding power to the loads. Export to the grid can be controlled from 0Watt to maximum power.
Therefore, inverters will be equipped to detect and mitigate faults, ensuring system reliability and minimizing downtime. Moreover, robust control strategies will enable PV systems to operate autonomously during grid disturbances, providing essential services such as islanding and grid support functions.
However, these methods may require accurate modelling and may have higher implementation complexity. Emerging and future trends in control strategies for photovoltaic (PV) grid-connected inverters are driven by the need for increased efficiency, grid integration, flexibility, and sustainability.
When upgrading the grid-tied system to an energy storage system the only part that changes is the AC Coupled battery inverter add-on. The existing solar PV system doesn’t need to change at all. The AC coupled battery inverter is installed alongside batteries which is then connected directly to your panel or mains.
