grid-tie system
[/ɡrɪd taɪ ˈsɪstəm/]
nounpl: grid-tie systems
sistema conectado à rede
1. A renewable energy system, typically solar or wind-powered, that is connected directly to the electrical utility grid, allowing excess energy to be fed back to the grid
The house has a grid-tie system installed on its roof that reduces electricity bills by feeding surplus solar energy back to the utility company.
A casa tem um sistema conectado à rede instalado no telhado que reduz contas de eletricidade alimentando energia solar excedente de volta à companhia de energia.
2. A photovoltaic or wind energy installation that operates in synchronization with the public electrical grid without requiring battery storage
Unlike off-grid systems, a grid-tie system does not need expensive batteries because it relies on the grid as backup.
Diferentemente dos sistemas isolados, um sistema conectado à rede não precisa de baterias caras porque depende da rede como backup.
Grid-tie systems have become increasingly popular in Brazil due to government incentives and rising electricity costs. In the USA, they are the most common type of residential solar installation. The terminology varies between regions, with Brazilian Portuguese preferring 'sistema conectado à rede' while European Portuguese uses 'sistema ligado à rede'. This technology is central to discussions about renewable energy adoption and energy independence in both countries.
