1. What is Inverter Battery Backup?

The inverter battery backup time indicates how long your battery can power your home appliances during a power outage. It depends on your battery capacity (Ah), battery voltage (V), and the total power consumption (W) of your connected devices.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{Battery Ah} \) — Battery capacity in amp-hours
• \( V \) — Battery voltage (typically 12V, 24V, or 48V)
• \( \text{Load W} \) — Total power consumption of connected devices in watts

Explanation: The equation calculates how many hours your battery can supply power to your load before needing recharge.

3. Importance of Backup Time Calculation

Details: Knowing your backup time helps in proper power management during outages, selecting the right battery capacity, and planning essential device usage.

4. Using the Calculator

Tips: Enter battery capacity in Ah, battery voltage in volts, and total load in watts. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: This provides an estimate. Actual backup time may vary due to battery age, temperature, inverter efficiency, and other factors.

Q2: What's a typical battery voltage for home inverters?
A: Common voltages are 12V, 24V, or 48V depending on system size.

Q3: How do I calculate my total load?
A: Sum the wattage of all devices you plan to run simultaneously during outage.

Q4: Does battery type affect backup time?
A: Yes, different battery types (lead-acid, lithium) have different discharge characteristics.

Q5: Should I include inverter efficiency in calculation?
A: For more accuracy, you can divide the result by inverter efficiency (typically 0.85-0.95).
