Will the inverter voltage flow backwards

When photovoltaic panels are connected to inverters, electricity will flow backwards under certain conditions - a phenomenon causing headaches for solar installers worldwide. But what triggers this reverse power flow, and could it actually damage your grid-tie system?. Reverse power flow occurs when the power generated by a grid-connected solar PV system exceeds the on-site consumption and flows back into the utility grid. ” Most power grids have strict regulations against unauthorized reverse power injection, which can lead to penalties. If the local load is not enough to soak up that power it is fed back to the grid it does not leak out into the OPs house or put simply the inverter deals with the excess power. There has to be a preventative measure. Think of it like water moving down a hill. Because electricity goes from high voltage to low voltage, the power "flows" just like that. . In DC, electricity is maintained at constant voltage in one direction. [PDF]
