On-Grid and Off-Grid Solar System: Connection and CalculatorSolar systems are mainly of two types: On-Grid Solar System and Off-Grid Solar System. Both use solar panels to generate electricity, but their connections and working processes are different.
1. On-Grid Solar System
Connection: Solar panels → DC protection → On-grid inverter → AC protection → Home distribution board → Electricity grid through a bidirectional meter.Works with the electricity grid.Usually does not require batteries.Can export surplus electricity to the grid, subject to applicable rules.Normally shuts down during a grid outage for safety.
2. Off-Grid Solar System
Connection: Solar panels → Solar charge controller (or compatible hybrid inverter) → Battery bank → Inverter → Home loads.Works independently of the electricity grid.Requires batteries for storing electricity for nighttime and backup.Useful where grid electricity is unavailable or unreliable.System capacity depends on daily consumption and the required backup hours or days
.3. On-Grid vs Off-Grid Comparison
