1. What is a Solar Generator Wattage Calculator?

Definition: This calculator determines the continuous wattage output a solar generator can provide based on its battery capacity and desired runtime.

Purpose: It helps users understand the power capabilities of their solar generator systems for various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Continuous wattage output (Watts)
• \( B \) — Battery capacity (Watt-hours)
• \( H \) — Hours of operation (hours)

Explanation: The battery capacity in watt-hours is divided by the desired runtime in hours to determine the continuous power output in watts.

3. Importance of Wattage Calculation

Details: Proper wattage calculation ensures your solar generator can adequately power your devices for the required duration without overloading the system.

4. Using the Calculator

Tips: Enter the battery capacity in watt-hours (Wh) and the desired runtime in hours (h). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my battery's watt-hour rating?
A: Multiply the battery's voltage (V) by its amp-hour (Ah) rating (e.g., 12V 100Ah = 1200Wh).

Q2: Does this account for inverter efficiency?
A: No, for more accurate results, divide the result by your inverter's efficiency (typically 0.85-0.95).

Q3: What's a typical watt-hour rating for solar generators?
A: Portable units range from 200-2000Wh, while whole-home systems can be 10,000Wh or more.

Q4: Can I use this for battery banks?
A: Yes, this works for any battery system when you know its watt-hour capacity.

Q5: How does solar charging affect this calculation?
A: This calculates discharge rate only. Solar charging capability depends on panel wattage and sunlight hours.
