Interpret results by comparing expected duration against your actual usage patterns. Avoid inputting incorrect wattage values, as this skews results significantly.

Backend Formula for the How Long Will a 200Ah Solar Battery Last Calculator

The core formula is:

Battery Life (hours) = (Battery Capacity in Ah * Battery Voltage) / Device Power Consumption in Watts

For example, using a 200Ah battery at 12V with a 100W device:

Battery Life = (200Ah * 12V) / 100W = 24 hours

Alternative approaches may consider battery efficiency losses, but the above formula provides a robust starting point for standard scenarios.

Step-by-Step Calculation Guide for the How Long Will a 200Ah Solar Battery Last Calculator

Here’s how to manually calculate battery life:

Determine the total power consumption of connected devices.
Multiply the battery capacity by its voltage to find the total energy available.
Divide total energy by device power consumption to find duration.

Example 1: A 200Ah battery at 12V running a 50W fan.

Total energy = 200Ah * 12V = 2400Wh
Duration = 2400Wh / 50W = 48 hours

Example 2: A 200Ah battery at 24V powering a 400W appliance.

Total energy = 200Ah * 24V = 4800Wh
Duration = 4800Wh / 400W = 12 hours

Ensure accuracy by double-checking inputs and accounting for device variability.
