Challenge Problems
Push your limits with advanced challenges
A community center relies on a 24V battery bank (100Ah) to power its lighting (loads of 300W). Calculate the backup time considering a 70% system efficiency.
💡 Hint: Calculate the usable energy first, then find how long it can power the lighting.
If a battery can supply 600W for a load but has a total capacity of 200Ah at 12V. What is the maximum time this battery can last with a 50% DoD?
💡 Hint: Account for DoD in your calculations.
