Battery Bank Fundamentals
Amp-hours (Ah)
Amp-hours (Ah) represent the amount of electrical charge a battery can deliver at a constant current for one hour. It's a key metric for sizing battery banks.
- Higher Ah means longer discharge time.
- Crucial for determining backup duration.
Watt-hours (Wh) and Voltage (V)
- Watt-hours (Wh) measure the total energy stored in a battery (Voltage × Amp-hours).
- Voltage (V) is the electrical potential difference of the battery system.
- These two values are essential for converting to Amp-hours.
Key Formula:
Amp-hours (Ah) = Watt-hours (Wh) / Voltage (V)
Calculation Formulas
Amp-hours (Ah):
Ah = Wh / V
Example Calculation
Consider a battery bank with:
Total Watt-hours (Wh): 1200 Wh
System Voltage (V): 12 V
Ah = 1200 Wh / 12 V
Ah = 100 Ah
Result: 100.00 Ah
