Solar Power System k Working detail mein:
1. *Solar Panel (Photovoltaic Module)*:
– Sunlight ke photons solar cells (silicon) pe hit hote hain.
– *Photovoltaic effect* se DC (direct current) electricity generate hotī hai.
– Output voltage ~18-20V DC (12V system ke liye).
2. *MPPT Solar Charge Controller*:
– *Maximum Power Point Tracking (MPPT)* algorithm panel se maximum power extract kartā hai.
– Input DC voltage ko optimize karke battery charging voltage (12V) mein convert kartā hai.
– Overcharge, over-discharge, short-circuit protection providē kartā hai.
– Display shows: solar voltage, battery voltage, charging current.
3. *Battery (12V LiFePO4)*:
– Solar controller se DC enerġī store kartī hai.
– 300AH capacity means 12V × 300AH = 3600WH energy storage.
– LiFePO4 safe, long life (5000 cycles), stable chemistry hai.
4. *Power Inverter (3000W Pure Sine Wave)*:
– Battery se DC 12V input leta hai.
– *Inverter* DC ko AC 220V/230V (50Hz) mein convert kartā hai.
– Pure sine wave output sensitive appliances (TV, fridge) ke liye perfect hotā hai.
– Overload & short-circuit protection built-in hotī hai.
5. *Disconnectors (Isolator Switches)
– Manual switches jo circuit ko isolate karte hain maintenance ke liye.
– Safety device jo electric shock or fire se bachātā hai.
6. *AC Load (Appliances)*:
– Inverter se AC power miltā hai.
– Devices: lights, fan, TV, washing machine, refrigerator.
– Total load inverter capacity (3000W) se match karna chahiye.
Step-by-step energy flow:
1. *Sunlight → Solar Panel* → DC electricity.
2. *Panel → MPPT Controller* → Optimized charging voltage.
3. *Controller → Battery* → Energy storage.
4. *Battery → Inverter* → DC to AC conversion.
5. *Inverter → Disconnectors → Appliances* → Power supply.
Key points to ensure efficient working:
– *Proper wiring*: Correct gauge (thickness) cables use karne chahiye to voltage drop avoid ho.
– *Maintenance*: Panels clean rakhein, battery terminals check karte rahein.
– *Load management*: Inverter capacity (3000W) se zyada load na lagāyē.
– *Safety*: Grounding & fuses lagānā zaroori hai.

Key wiring points:
1. *Solar Panel → MPPT Controller*:
– Solar panel ke positive (+) & negative (-) wires controller ke input terminals se connect hote hain.
– Use MC4 connectors for panel connections.
2. *MPPT → Battery*:
– Controller output battery ke (+) & (-) terminals se connect hota hai.
– Cable size: 6mm² or 10mm² (depends on distance).
3. *Battery → Inverter*:
– Battery se inverter ke DC input (+) & (-) connect karen.
– Use thick cables (10-16mm²) for high current flow.
4. *Inverter → Disconnectors → Loads*:
– Inverter AC output disconnectors se, phir appliances ko jātā hai.
– Use 2.5mm² or 4mm² AC cables.
5. *Grounding*:
– Inverter & disconnectors ka grounding earth pit se connect karen.
– Safety: Prevents electric shock & surge damage.
Performance Calculation (Energy Yield):
– *Solar panel output*: ~1kW peak (depends on location & efficiency).
– *Battery backup*: 3600WH (12V × 300AH).
– If load = 1000W, backup ~3.6 hours.
– *Inverter capacity*: 3000W, can run:
– 2 LED bulbs (20W each) + 1 fan (50W) + 1 TV (100W) = ~200W load.
– Runtime: ~18 hours (3600WH ÷ 200W).
Safety Tips:
1. *Fuses*: Add fuses between battery & inverter, controller & battery.
2. *Cable protection*: Use conduit/trunking for wiring.
3. *Ventilation*: Inverter & battery ko ventilated area mein rakhen.
4. *Check connections*: Loose wires or corrosion check karte rahen.
