Off-grid refers to systems that operate independently of the traditional electrical grid, often relying on renewable energy sources such as solar panels, wind turbines, or hydroelectric generators for power generation. These systems are typically used in remote or rural areas where grid connection is impractical or unavailable. Off-grid setups require careful planning and integration of energy storage solutions like batteries to store excess energy for use during periods of low generation. While offering autonomy and sustainability, off-grid systems require upfront investment and ongoing maintenance but provide resilience against grid failures and offer environmental benefits by reducing reliance on fossil fuels.
