Run Time Formula:
| From: | To: |
The solar generator run time is the duration a solar generator can power your devices based on its battery capacity and the power consumption of your load. Understanding this helps in planning for power needs during outages or off-grid situations.
The calculator uses the simple formula:
Where:
Explanation: This formula divides the total available energy by the rate of energy consumption to determine how long the power will last.
Details: Accurate run time estimation is crucial for emergency preparedness, outdoor activities, and ensuring continuous power for essential devices during outages.
Tips: Enter battery capacity in watt-hours (Wh) and load power in watts (W). Both values must be greater than zero for accurate calculation.
Q1: How can I find my device's power consumption?
A: Check the device's label or manual for wattage information, or use a watt meter to measure actual consumption.
Q2: Does this account for inverter efficiency losses?
A: No, this is a theoretical calculation. Actual run time may be 10-15% less due to conversion losses.
Q3: What if my device lists amps instead of watts?
A: Convert amps to watts by multiplying by voltage (Watts = Amps × Volts).
Q4: Can I extend my generator's run time?
A: Yes, by reducing load power, adding more battery capacity, or using solar panels to recharge during use.
Q5: Is this calculation accurate for lithium batteries?
A: Yes, but note that lead-acid batteries typically shouldn't be discharged below 50% capacity.
