6 FAQs about [Energy storage inverter DC side voltage platform]

What is a grid-tied photovoltaic (PV) & energy storage inverter?

Introduction Modern grid-tied photovoltaic (PV) and energy storage inverters are designed with control capabilities that can support and/or enhance the existing global grid infrastructure. Inverter-based generation is growing today in the residential, commercial, and utility segments.

What are inverter grid support functions?

Inverter grid supporting functions along with voltage and frequency ride through, provide key behaviors that both support and enhance grid reliability. Today’s PV and energy storage inverters can be deployed individually and in a mixed design affording plant designers’ options for energy capture and grid support.

Should a PV inverter have DC-coupled storage?

Adding DC-coupled storage to a PV inverter in this scenario can overcome these challenges by using the storage as a buffer, helping to smooth out the PV inverter’s output power without increasing the nameplate rating of the plant. Frequency is held to a very strict tolerance, therefore, deltas in frequency must be mitigated.

How do PV inverters support grid frequency?

Grid frequency support is achieved by adjusting inverter real power output. This functionality is limited with PV inverters because the inverters are following the DC energy provided to them by the sun. For a grid high frequency event, PV inverters can be easily set to reduce active power to help reduce the grid frequency.

What type of inverter is used in the utility market?

From a market perspective, the utility market is largely served by central inverters, which will be the focus of this article. The commercial and industrial market is largely served by three-phase string, or mini-central, inverters. The residential market is still dominated by single-phase string inverters and module-level micro inverters.

Why should I increase the DC-AC ratio on a PV inverter?

SMA ENERGY STORAGE SOLUTIONS: RENEWABLE INTEGRATION As module prices continue to decline, increasing the DC-AC ratio on a PV inverter continues to add benefit by allowing more energy production during the shoulder hours. The downside is that there is a large amount of energy loss due to inverter clipping since they have maximum AC power limits.
