1. What is Battery Capacity?

Battery capacity is a measure of the charge stored in a battery, typically measured in ampere-hours (Ah). It indicates how much energy a battery can deliver at a specific voltage over time.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Wh \) — Watt-hours (energy capacity from Amazon Australia)
• \( V \) — Voltage of the battery system

Explanation: The formula converts energy capacity (Wh) to charge capacity (Ah) by dividing by the battery voltage.

3. Importance of Battery Capacity Calculation

Details: Knowing your battery's capacity in Ah helps determine how long your solar system can power your devices and ensures proper system sizing.

4. Using the Calculator

Tips: Enter the watt-hour (Wh) rating from Amazon Australia product specifications and the nominal voltage of your battery system. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why use Amazon Australia Wh ratings?
A: Amazon Australia provides standardized Wh ratings for many solar products, making it a reliable source for calculations.

Q2: What are typical battery voltages?
A: Common voltages include 12V, 24V, or 48V for solar systems. Check your battery specifications.

Q3: How accurate is this calculation?
A: It provides theoretical capacity. Actual capacity may vary due to temperature, age, and discharge rates.

Q4: Can I use this for lithium batteries?
A: Yes, the formula works for any battery type as long as you have the correct Wh and V values.

Q5: How does this relate to solar panel sizing?
A: Battery capacity helps determine how much solar panel output you need to recharge your batteries effectively.
