Li90 30kVA — slimmest and lightest 30kVA lithium UPS for retrofit and space-constrained installations

The Li90 30kVA is the slimmest and lightest 30kVA lithium UPS available — 12.6″ wide and approximately 483 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.

Retrofit and Space-Constrained Installations

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.

12.6″

Cabinet width — narrowest 30kVA available

Fits through standard doors. Installs in aisles where 24–36″-wide conventional systems cannot maneuver or fit at the installation site.

~483

System weight (lbs) — 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.

0

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.

50°C

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.

VRLA Replacement

Li90 30kVA vs. traditional 30kVA VRLA UPS systems

Many facilities running legacy 30kVA VRLA UPS systems — including the Eaton 93E, Vertiv EXS, and APC Galaxy VS — 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.

Platform Features

Li90 30kVA features

Li90 4.3 inch color touchscreen showing the single-line mimic diagram with bypass, rectifier, inverter, and output stages and operating data
The 4.3″ touchscreen — single-line mimic, phase voltages, frequency, event logging, and ON/OFF/EPO controls

Online double-conversion — zero transfer time

Output is regenerated through the inverter at all times. No transfer delay during utility events. Clean, regulated, isolated 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 30kVA 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.
