Li90 30kVA vs APC Easy UPS 3S
The Xtreme Power Li90 30kVA and APC Easy UPS 3S are 30 kVA online double-conversion three-phase UPS with integrated maintenance bypass for data center, industrial, and healthcare loads. Both deliver full-rated power; the Li90 differentiates on LFP battery life, efficiency and heat, runtime, operating temperature, footprint and weight, and warranty, while the Easy UPS 3S is a traditional VRLA platform.
What the Li90 (30kVA) brings
- LiFePO₄ batteries, up to 5× longer life
- Higher efficiency, lower heat (94.5% vs 94%, 5,954 vs 7,161 BTU/hr)
- Longer internal runtime at full load (15 vs 10.5 min)
- Operation to 50 °C (122 °F)
- Smaller and lighter; 5-year battery warranty vs 1-year

Choosing between them
The Li90 leads on battery life, efficiency and heat, runtime, operating temperature, footprint, weight, and warranty; the Easy UPS 3S is a traditional VRLA platform for APC-standardized sites with controlled cooling. Capacity, topology, and bypass are equivalent.
Choose the Li90 (30kVA) if you need
- Lithium UPS technology with long service life
- Higher efficiency and lower thermal output
- Longer runtime without external batteries
- Operation up to 50 °C and a smaller, lighter footprint
- Longer battery and system warranty coverage
The APC Easy UPS 3S may fit if you need
- A traditional VRLA-based online UPS
- Compatibility with existing APC Easy UPS deployments
- Standard operating conditions with controlled cooling
Frequently asked questions
Both are 30 kVA online double-conversion three-phase UPS with integrated maintenance bypass. The Li90 uses LFP for far longer battery life, runs slightly more efficiently with less heat (94.5 vs 94%), tolerates 50 C, and is smaller and lighter; the Easy UPS 3S is a traditional VRLA platform.
The Li90, about 15 minutes at full 30 kW load versus about 10.5 for the Easy UPS 3S at its maximum internal configuration.
Yes, about 5,954 BTU/hr versus 7,161 for the Easy UPS 3S, which lowers cooling load in the electrical room.
LFP batteries last far longer than VRLA, tolerate higher temperatures, and cut replacement and maintenance over the system’s life. VRLA remains a lower up-front-cost, established option.
