Inverter Usage Calculator

Formula

To calculate the Usage Time (UT):

\[ UT = \frac{BC \times 12 \times IE}{LP} \]

Where:

\(UT\) is the Usage Time (hours)
\(BC\) is the Battery Capacity (Ah)
\(IE\) is the Inverter Efficiency (decimal)
\(LP\) is the Load Power (W)

What is Inverter Usage Time?

Inverter usage time refers to the duration an inverter can supply power to a load before the battery is depleted. It is a crucial factor for those relying on inverters for backup power or off-grid power systems. Understanding the usage time helps in planning energy consumption and ensuring that critical loads are supported during power outages or in remote locations.

Example Calculation

Let's assume the following values:

Battery Capacity (\(BC\)) = 100 Ah
Inverter Efficiency (\(IE\)) = 0.9
Load Power (\(LP\)) = 500 W

Using the formula:

\[ UT = \frac{100 \times 12 \times 0.9}{500} = \frac{1080}{500} = 2.16 \text{ hours} \]

The Usage Time is 2.16 hours.
