1. System Requirements for 48V 1800W Induction Cooktop (4 Hours Per Day)

1. Cooktop Power:
   • 1800W induction cooktop running for 4 hours per day.
2. Energy Consumption Calculation:
   • Energy required per day (Wh) = Power (W) × Cooking hours (h)
     • 1800W × 4 hours = 7200Wh per day.

2. Battery Requirements

1. Battery Voltage:
   • System operates on 48V.
   • Using 12V batteries, they must be connected in series to reach 48V.
2. Battery Capacity Calculation:
   • Required Battery Capacity (Ah) = Total Energy (Wh) ÷ System Voltage (V)
   • 7200Wh ÷ 48V = 150Ah required.
3. Number of Batteries:
   • Each 12V battery has 100Ah capacity.
   • To achieve 48V, batteries are connected in series (4 batteries per set).
   • To reach 150Ah, we need two sets of 4 batteries (total 8 batteries).
4. Battery Cost Calculation:
   • Estimated cost of 12V 100Ah battery = $0.146 per watt.
   • Cost per battery = $0.146 × (12V × 100Ah) = $175.20 USD.
   • Total cost for 8 batteries = $175.20 × 8 = $1401.60 USD.

3. Solar Panel Requirements

1. Daily Solar Energy Requirement:
   • 7200Wh per day.
2. Solar Panel Output:
   • Each 200W solar panel generates about 1600Wh per day (200W × 8 hours sunlight).
   • Panels Required = Total Energy / Panel Output
   • 7200Wh ÷ 1600Wh ≈ 4.5 → Round up to 5 solar panels.
3. Solar Panel Cost Calculation:
   • Each 200W solar panel costs $60 USD.
   • Total cost = 5 × $60 = $300 USD.

4. Charging Controller Requirements

1. Current Calculation for Controller:
   • Required current = Total Power (W) ÷ Voltage (V)
   • 1800W ÷ 48V = 37.5A.
   • A 50A charging controller is recommended.
2. Controller Cost Calculation:
   • Estimated cost of 50A Charging Controller = $15 USD.

5. Cable Requirements and Cost

1. Required Cable Lengths:
   • Solar Panel to Charging Controller = 15 meters.
   • Charging Controller to Battery = 1.5 meters.
   • Battery to Cooktop = 1.5 meters.
   • Total cable required = 18 meters.
2. Cable Cost Calculation:
   • Estimated cost per meter = $1 USD.
   • Total cost = 18 × $1 = $18 USD.

6. Induction Cooktop Cost

• 48V 1800W Induction Cooktop Cost = $100 USD.

7. Total Cost Breakdown (in USD)

Summary

For the 48V 1800W induction cooktop, with 4 hours of cooking per day, the total cost breakdown (in USD) is approximately $1834.60. This includes:

• 5 Solar Panels (200W each): $300.00
• 8 Acid Batteries (12V, 100Ah each): $1401.60
• 50A Charging Controller: $15.00
• Cables: $18.00
• Induction Cooktop (48V 1800W): $100.00

This setup ensures sufficient power storage and solar charging for a reliable, eco-friendly cooking solution.
