Solar Battery Bank Size Calculator- Off-Grid Battery Size Calculator
To calculate the required solar battery bank size, determine the total energy needs, days of autonomy, depth of discharge, and system voltage to size the battery bank effectively.
The Solar Battery Bank Size Calculator is a valuable tool for designing off-grid and backup power systems. Proper sizing ensures your solar battery bank stores enough energy to meet your needs, even during low sunlight or high usage.
Factors like total power consumption, days of autonomy, depth of discharge (DI), and system voltage (V) play a crucial role in calculating battery bank capacity. Whether you’re designing an off-grid solar system or upgrading your existing setup, this calculator simplifies the process and helps ensure optimal performance.
Formula:
BB = (P × D × DI) / (100 × V)
| Variable | Description |
|---|---|
| BB | Battery bank capacity (in amp-hours) |
| P | Total daily power consumption (watt-hours) |
| D | Number of days of autonomy |
| DI | Depth of discharge (percentage) |
| V | System voltage (volts) |
Solved Calculations
Example 1: Battery Bank for a Small Off-Grid System
| Step | Value |
|---|---|
| Daily Power Consumption (P) | 2,000 Wh |
| Days of Autonomy (D) | 2 |
| Depth of Discharge (DI) | 50% |
| System Voltage (V) | 24V |
| Battery Bank (BB) | (2000 × 2 × 50) / (100 × 24) = 83.33 Ah |
Example 2: Battery Bank for a Medium-Sized Solar Setup
| Step | Value |
|---|---|
| Daily Power Consumption (P) | 5,000 Wh |
| Days of Autonomy (D) | 3 |
| Depth of Discharge (DI) | 60% |
| System Voltage (V) | 48V |
| Battery Bank (BB) | (5000 × 3 × 60) / (100 × 48) = 187.5 Ah |
