Understanding the backup hours provided by a 12V 150Ah lead acid battery is crucial for ensuring uninterrupted power supply during outages or off-grid situations. In this blog post, we’ll guide you through the calculations and assumptions needed to determine the backup hours of this battery type. Immortals Solar is your trusted partner in renewable investments, offering expertise in reliable energy storage solutions.
Battery Capacity Basics
- Voltage: The battery’s voltage rating is 12V, indicating its compatibility with 12V systems.
- Capacity: The battery’s capacity is 150Ah (ampere-hours), representing the amount of charge it can hold.
Assumptions for Calculations
- Efficiency: Assuming an efficiency of 80% to account for losses during charging and discharging.
- Depth of Discharge (DoD): Considering a 50% DoD to prolong battery life and maintain performance.
Calculating Backup Hours
- Total Usable Capacity: Calculate the total usable capacity by multiplying the battery capacity (150Ah) by the DoD percentage (50%), resulting in 75Ah of usable capacity.
Total Usable Capacity = Battery Capacity (Ah) x Depth of Discharge (DoD)
Total Usable Capacity = 150Ah x 0.50 = 75Ah
- Power Consumption: Estimate the power consumption of your load in watts (W) or kilowatts (kW) per hour.
- Calculating Backup Hours: Divide the total usable capacity (in ampere-hours, Ah) by the power consumption of your load to determine the backup hours.
Backup Hours = Total Usable Capacity (Ah) / Power Consumption (Amps)
Example Calculation: If your load consumes 10 amps (A) per hour, the backup hours would be:
Backup Hours = 75Ah ÷ 10A = 7.5hours
