1. What is a Solar Generator Wattage Calculator?

Definition: This calculator determines the wattage output of a solar generator based on battery capacity and desired usage time.

Purpose: It helps solar energy users and professionals estimate power output for proper system sizing and energy planning.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W = \frac{B \times 1000}{H} \]

Where:

Explanation: The battery capacity is converted from kWh to watt-hours (×1000) then divided by the desired usage time to determine continuous wattage output.

3. Importance of Wattage Calculation

Details: Proper wattage estimation ensures your solar generator can power your devices adequately and helps prevent system overload or underperformance.

4. Using the Calculator

Tips: Enter the battery capacity in kWh and the desired usage time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply by 1000 in the formula?
A: This converts kilowatt-hours to watt-hours (1 kWh = 1000 Wh).

Q2: What's a typical battery capacity for home solar?
A: Residential systems typically range from 5-20 kWh, depending on energy needs.

Q3: Does this account for inefficiency?
A: No, this is theoretical maximum. For real-world use, consider 10-15% efficiency loss.

Q4: How do I find my battery's kWh rating?
A: Check manufacturer specifications or multiply battery voltage by amp-hour rating then divide by 1000.

Q5: Can I use this for multiple batteries?
A: Yes, simply sum the kWh ratings of all batteries in your system.
