P91g-2000 vs APC Smart-UPS SRT2200RMXLI
The P91g-2000 and APC Smart-UPS SRT2200RMXLI are both 208/230 V online double-conversion VRLA UPS for critical IT, networking, AV, and edge infrastructure. The P91g-2000 delivers higher usable real power at unity PF, a far higher programmable charger, faster recharge, and TAA compliance.
What the P91g-2000 brings
- Higher usable watts at unity PF (2000 W vs 1980 W)
- Programmable 1–12 A charger vs 1.5–2 A
- Faster recharge with extended batteries
- Scalable runtime with up to 8 external battery packs
- TAA compliance and longer battery warranty

Specifications from Xtreme Power’s supplied P91g-2000 vs APC SRT2200RMXLI comparison; confirm against current vendor documentation. The APC carries a higher VA rating (2200) but lower usable watts (1980 W).
Choosing between them
Both deliver equivalent online VRLA protection. The P91g-2000 leads on usable watts, charging, recharge, scalability, TAA, and battery warranty; the APC fits APC-standardized environments and carries an extra C19 outlet.
Choose the P91g-2000 if you need
- Full 2000 W usable output at unity power factor
- Faster battery recharge after outages
- Scalable runtime with external battery packs
- TAA compliance for government procurement
The Smart-UPS SRT2200RMXLI may fit if you need
- Standardization on existing APC infrastructure
- Deployments where slightly longer recharge is acceptable
- Projects not requiring TAA compliance
