This is shows a Hybrid Solar System Wiring layout—how solar + grid power + batteries work together through a hybrid inverter to run a home with backup power.
What each part is
- Solar panel (top right): Produces DC electricity from sunlight.
- Hybrid inverter (center): The “brain” of the system. It:
- converts DC (solar/battery) into AC for the house
- manages battery charging/discharging
- can also use the grid when needed
- Battery bank (right): Stores energy so the house can keep running at night or during outages.
- Electric pole / grid (top left): Utility power supply.
- MCB (Miniature Circuit Breaker) boxes: Safety breakers that protect wiring and equipment from overload/short circuits:
- one on the grid side
- one on the house output side
How power flows in real life (simple scenarios)
- Sunny daytime: Solar → inverter → powers the house first, and any extra can charge the batteries.
- Evening/night: Batteries → inverter → house.
- Low battery / high load: Grid → inverter → house (and sometimes charges batteries, depending on settings).
- Power outage (if your inverter supports backup mode): Batteries + solar keep essential loads running through the inverter.
Important safety note
This is a concept diagram, not a full code-compliant installation drawing. A real hybrid system usually also needs correct earthing/grounding, DC isolators, fuses, surge protection (SPD), proper cable sizes, and approved enclosures—all per local electrical code and inverter manual. If you’re installing one, use a qualified electrician/solar installer.
