1. Dependence on the main grid: Grid-connected systems still rely on the main grid as their primary source of power. They need to draw electricity from the grid to operate, so they can''t operate autonomously during grid outages. 2. One-way power flow: Grid-connected systems typically have a one-way power flow, where electricity flows
