Li90 30 kW: Slim, Lightweight Lithium UPS
The Li90 30 kW is the slimmest and lightest 30 kW lithium UPS available: 12.6″ wide and approximately 485 lbs. It delivers full 30kW three-phase power with integrated LiFePO₄ batteries in a single compact cabinet, designed specifically for retrofit installations and space-constrained electrical environments where traditional 30kVA VRLA UPS systems cannot fit or exceed floor-loading limits. Factory start-up and 2 years of on-site service are included in the USA.

Designed for locations where conventional 30kVA UPS systems cannot fit
Legacy 30kVA VRLA UPS systems are typically wide, heavy, and dependent on external battery cabinets. The Li90 was engineered to replace these installations in constrained electrical rooms, telecom shelters, and edge deployments — combining the power electronics and lithium batteries in a single cabinet that fits through standard doors and service aisles.
Cabinet width: narrowest 30 kW available
Fits through standard doors. Installs in aisles where 24–36″-wide conventional systems cannot maneuver or fit at the installation site.
System weight — dramatically lower floor loading
Conventional 30kVA VRLA systems weigh 900–1,500 lbs combined with battery cabinets. Li90 reduces floor loading, seismic anchoring requirements, and installation rigging cost.
External battery cabinets required
LiFePO₄ batteries integrate inside the UPS enclosure — no separate battery frames, no additional floor-space allocation, and no additional electrical connections for battery cabinets.
Operating temperature — no cooling required
Deploy in electrical rooms, telecom shelters, and edge sites that exceed VRLA operating limits — without adding dedicated cooling infrastructure to support the UPS replacement.

Li90 30 kW vs. traditional 30kVA VRLA UPS systems
Many facilities running legacy 30kVA VRLA UPS systems, including the Eaton 93E and Vertiv EXS, are managing external battery cabinets that consume floor space and require replacement every 3–5 years. The Li90 provides a direct replacement path with significantly reduced footprint, weight, and lifecycle cost.
| Feature | Li90 30 kW | Typical 30kVA VRLA UPS |
|---|---|---|
| Cabinet width | 12.6″ | 24–36″ |
| System weight | approx 485 lbs | 900–1,500 lbs |

Li90 30 kW features

Online double-conversion — zero transfer time
Output is regenerated through the inverter at all times. No transfer delay during utility events. Clean, regulated output power regardless of input conditions.
50°C operation — harsh and unconditioned environments
Reliable operation to 50°C (122°F) without derating until 40°C. Telecom shelters, industrial electrical rooms, edge data centers, and outdoor equipment rooms where VRLA systems are not viable without supplemental cooling.
Hot-swappable LiFePO₄: 3 modules required
The 30 kW model requires all 3 battery modules — up to 15 minutes runtime at 30kW, 18 minutes at 25kW. Modules are replaced without tools and without powering down the load. Up to 15-year battery service life.
4.3″ touchscreen · SNMP · dry contacts
Color touchscreen with single-line mimic, event log, and security control. Two SNMP/Web card slots. Programmable dry contacts (1 in / 5 out) for facility and BMS integration.
Maintenance bypass — integrated
Input, output, bypass, and maintenance-bypass breakers all integrated in the cabinet. Safe on-site servicing without powering down the load. No external switchgear required.
Conformal-coated PCBs — industrial environments
Circuit boards are conformal coated for industrial and high-humidity environments. The smart self-cleaning fan system extends service life in dusty or contaminated-air environments.
