System Requirements for 48V 1200W Induction Cooktop (6 Hours Per Day)

1. Cooktop Power:
   • 1200W induction cooktop for 6 hours of daily cooking.
2. Energy Consumption Calculation:
   • Energy used per day (Wh) = Power (W) × Cooking hours (h)
     • 1200W × 6 hours = 7200Wh per day
3. Battery Storage:
   • Lithium Battery Voltage: Each battery is 12V.
   • Battery backup is required for 2 days (assuming evening cooking will charge the battery during the day).
   • Total required battery storage for 2 days = 7200 Wh × 2 = 14,400 Wh.

Battery Capacity (Ah) = Total energy required (Wh) / Battery Voltage (V):

• 14,400 Wh / 12V = 1,200 Ah capacity required.

Required Number of Batteries:

• If each 12V battery has 100Ah capacity, then:
  • 1,200 Ah / 100 Ah per battery = 12 batteries.

4. Solar Panel Requirements:
   • Solar Panel Wattage: 200W each panel.
   • Daily energy requirement (7200 Wh) from solar panels:
     • Required Solar Panel Wattage = Total energy required / Solar panel daily output.
     • Daily panel output = 200W × 8 hours of sunlight = 1600 Wh per panel per day.
     • Number of panels required = 7200 Wh / 1600 Wh ≈ 4.5 → 5 solar panels.
5. Charging Controller:
   • Charging Controller Specification: The controller should be capable of charging the batteries from the solar panels. The controller should handle the energy output from 5 panels.
   • Controller capacity: 35A.
   • Estimated cost of 35A Controller = $10 USD.
6. Cable Requirements:
   • Solar Panel to Charging Controller: 15 meters of cable.
   • Charging Controller to Battery: 1.5 meters of cable.
   • Battery to Cooktop: 1.5 meters of cable.
   • Estimated cable cost: $1 per meter.
   • Total cable cost = 18 meters × $1 = $18 USD.

Price Breakdown (in USD)

1. Solar Panel:
   • Each 200W solar panel costs $60 USD.
   • For 5 panels:
     • 5 × $60 = $300 USD.
2. Acid Battery (12V):
   • Battery capacity required = 1,200 Ah.
   • Estimated cost of 12V 100Ah Acid Battery per watt = $0.146 per watt.
   • Cost per 12V 100Ah battery:
     • Each 12V 100Ah battery provides 1,200 Wh of storage capacity (12V × 100Ah = 1,200Wh).
     • Cost per battery = $0.146 × 1,200 = $175.20 USD per 12V 100Ah battery.
   • Required Number of Batteries:
     • 12 batteries × $175.20 = $2,102.40 USD.
3. Charging Controller:
   • 35A charging controller for the batteries:
     • $10 USD.
4. Cables:
   • Solar Panel to Controller (15m): 15 × $1 = $15 USD.
   • Controller to Battery (1.5m): 1.5 × $1 = $1.50 USD.
   • Battery to Cooktop (1.5m): 1.5 × $1 = $1.50 USD.
   • Total cable cost:
     • $15 + $1.50 + $1.50 = $18 USD.
5. Induction Cooktop (48V 1200W):
   • Estimated cost of 48V 1200W induction cooktop = $76 USD.

Total Cost Breakdown:

Summary

For the 48V 1200W induction cooktop, with 6 hours of cooking per day, the total cost breakdown (in USD) is approximately $2,506.40. This includes:

• 5 Solar Panels (200W each): $300.00
• 12 Acid Batteries (12V, 100Ah each): $2,102.40
• 35A Charging Controller: $10.00
• Cables: $18.00
• Induction Cooktop (48V 1200W): $76.00

This configuration provides a reliable, solar-powered cooking solution with enough backup to support 6 hours of cooking daily while maintaining the ability to recharge efficiently during daylight hours.
