P91-2000 vs APC Smart-UPS SRT2200XLA
The P91-2000 and APC Smart-UPS SRT2200XLA are both true online double-conversion UPS on VRLA batteries for mission-critical IT, network, and edge infrastructure. Despite a lower VA rating, the P91-2000 delivers higher usable watts, plus a shallower depth, more standard outlets, longer battery design life, and full TAA compliance.
What the P91-2000 brings
- Higher usable watts (1930 W vs 1800 W) despite lower VA
- Shallower rack depth (20.0 in vs 23.0 in)
- More standard outlets without locking-plug dependency
- Longer battery design life (3–5 yr vs 2 yr) and warranty
- TAA compliance for federal procurement

Choose the P91-2000 if you need
- Edge, IDF, and MDF deployments with limited rack depth
- Federally funded and TAA-restricted procurement
- More standard receptacles without locking plugs
- Longer battery life and lower lifecycle cost
The Smart-UPS SRT2200XLA may fit if you need
- Existing APC-standardized environments
- Locking receptacles for specific loads
- Climate-controlled, full-depth racks where TAA isn’t required
