30 kVA · 208/120 V Three-Phase · Online Lithium (LiFePO₄) UPS Comparison

Li90 30kVA vs APC Galaxy VS 30kVA

The Xtreme Power Li90-30k and APC Galaxy VS 30kVA are 30 kVA three-phase online double-conversion UPS for facility power in 208/120 V environments, both internal-battery systems. The Li90 uses lithium iron phosphate while the Galaxy VS uses VRLA. The Li90 differentiates on battery lifecycle, thermal tolerance, runtime, cabinet size, and weight; the Galaxy VS holds a slight online-efficiency edge.

Choose the Li90-30k if you need

  • Lithium iron phosphate lifecycle (longer life, less maintenance)
  • Operation to 50 °C
  • Longer internal runtime
  • A much smaller, lighter cabinet
  • Facility modernization with predictable lifecycle cost

The APC Galaxy VS may fit if you need

  • A slightly higher online efficiency
  • An established VRLA platform with enterprise deployment history
  • Alignment with an existing Schneider / APC standard
Questions

Frequently asked questions

How do the Li90-30k and Galaxy VS 30kVA differ?

Both are 30 kVA online double-conversion three-phase UPS with internal batteries. The Li90 uses lithium iron phosphate (LFP) for longer service life, higher thermal tolerance (50 vs 40 C), and a much smaller, lighter cabinet; the Galaxy VS uses VRLA and holds a slight online-efficiency edge (95.2% vs 94.5%).

Which runs longer on internal batteries?

The Li90-30k, about 15 minutes on three strings versus about 11 for the Galaxy VS on five. The Li90 also weighs under half as much (483 lbs vs over 1000).

Is the Galaxy VS more efficient?

Slightly, at this capacity, up to 95.2% online versus the Li90’s 94.5%. Over a lifecycle, the Li90’s lithium chemistry (longer life, fewer battery replacements, 50 C tolerance) is the larger cost factor for most facilities.

Why choose lithium over VRLA here?

LFP batteries last longer, tolerate higher temperatures, and reduce replacement and maintenance planning over the system’s life, which is the Li90’s modernization argument. VRLA remains a lower up-front-cost, established option.
