PV Inverters Enter the Grid-Forming Era

As distributed energy sources like solar and storage penetrate the grid at scale, inverters are evolving from simple power converters into critical assets for grid stability. According to SNEC PV+ 2026, more inverter and PCS manufacturers now prioritize grid support capabilities alongside traditional metrics like conversion efficiency and power density.

This shift is driven by updated international grid codes. Standards such as IEEE 1547-2018, UL 1741 SB, and EN 50549 require inverters to feature fault ride-through (FRT) capability, maintaining grid connection during transient under-voltage or over-voltage events rather than disconnecting immediately. Depu New Energy's PV inverters follow this technical direction, with optimized low-voltage ride-through (LVRT) and high-voltage ride-through (HVRT) performance to meet major global grid certification requirements. Through rigorous quality control, Depu ensures long-term operational reliability for household distributed PV systems. As renewable generation continues to grow, grid-forming inverters will become core infrastructure in new power systems, and Depu is well-positioned to seize this opportunity.
