The Xtreme Power Conversion P91-1500 and WattBox WB-OVRC-OLUPS-1500-1 are true online, double-conversion UPS systems designed to protect network, IT, AV, and edge infrastructure. Both deliver continuous sine-wave output and enterprise-grade protection from power disturbances.
However, the P91-1500 differentiates itself with greater installation flexibility, full TAA compliance, more built-in receptacles, lighter weight, and stronger battery warranty coverage, making it especially well suited for space-constrained deployments, government and public-sector projects, and installations focused on long-term total cost of ownership.
