On-grid systems draw power directly from the utility network, maintaining a steady and dependable supply where outages are uncommon and electricity remains affordable. Off-grid systems function independently by generating power through renewable sources such as solar, wind, or water and storing that energy in dedicated batteries. They serve locations where grid access is impractical or energy costs are excessive. Off-grid setups emphasize long-term sustainability and operational freedom, with higher initial costs offset by greater independence and control.
