24V System Applications

Solar Power Systems

24V battery banks are common in medium-sized solar installations. They offer a good balance between efficiency and component availability.

  • • Lower current than 12V systems
  • • Reduced wire size requirements
  • • Better for longer wire runs

Heavy Trucks & Equipment

Commercial trucks, buses, and heavy equipment use 24V systems for more efficient power delivery to starters and accessories.

  • • Diesel truck starting systems
  • • Construction equipment
  • • Military vehicles

Industrial Applications

24V DC is widely used in industrial control systems, PLCs, sensors, and automation equipment.

Battery Backup Systems

UPS systems and emergency backup power often use 24V battery configurations for critical equipment.
