Li90 10kVA vs APC Galaxy VS 10kVA Compact Tower
The Xtreme Power Li90-10k and APC Galaxy VS 10kVA Compact Tower are 10 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 for longer life, higher thermal tolerance, a slight efficiency edge, and lighter weight; the Galaxy VS Compact Tower offers longer internal runtime in this configuration and a narrower cabinet.
What the Li90-10k brings
- Lithium iron phosphate batteries (longer life, less maintenance)
- Slightly higher online efficiency (94.5% vs 94%)
- Rated to 50 °C vs 40 °C
- Shorter cabinet height
- Lighter (447 lbs vs 725 lbs)

Specifications based on publicly available manufacturer documentation; confirm against current vendor data. At 10 kVA the Galaxy VS Compact Tower internal-battery configuration provides longer runtime.
Choosing between them
The Li90 leads on battery lifecycle (LFP vs VRLA), thermal tolerance, efficiency, and weight; the Galaxy VS Compact Tower offers longer internal runtime and a narrower cabinet at this capacity. Topology and unity power factor are equivalent.
Choose the Li90-10k if you need
- Lithium iron phosphate lifecycle (longer life, less maintenance)
- Operation to 50 °C
- A slight efficiency edge and lighter weight
- Facility modernization with predictable lifecycle cost
The APC Galaxy VS Compact Tower may fit if you need
- Longer internal runtime at 10 kVA (up to 56 min)
- A narrower cabinet footprint
- An established VRLA platform / existing APC standard
Frequently asked questions
Both are 10 kVA online double-conversion three-phase UPS with internal batteries. The Li90 uses LFP for longer life, higher thermal tolerance (50 vs 40 C), a slight efficiency edge (94.5% vs 94%), and lighter weight; the Galaxy VS Compact Tower offers longer internal runtime in this configuration and a narrower cabinet.
At 10 kVA, the Galaxy VS Compact Tower, up to about 56 minutes on four strings versus up to 45 for the Li90 on three. If maximum internal runtime is the priority at this capacity, the Galaxy VS leads; the Li90 leads on weight, thermal tolerance, and lithium lifecycle.
The Li90, narrowly, up to 94.5% online versus the Galaxy VS Compact Tower’s up to 94%. The gap is small; chemistry and lifecycle are the larger differentiators.
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.
