48V System Applications

Large Solar Systems

48V is the standard for larger off-grid and hybrid solar installations. Lower current means smaller wires and less power loss over long cable runs.

Telecom Infrastructure

Cell towers, telephone exchanges, and network equipment standardize on -48V DC for reliability and safety.

Data Centers

Modern data centers increasingly adopt 48V DC distribution for improved efficiency over traditional AC power.

Golf Carts & EVs

Many golf carts and small electric vehicles use 48V battery systems for a balance of performance and safety.

Why Choose 48V?

  • 4x lower current than 12V for same power
  • 16x lower power loss (I²R losses)
  • Smaller wire sizes save cost
  • Still considered "low voltage" (safe)
  • Wide inverter/charger availability
