Toshiba G9000 Series, 100-2000 kVA

Toshiba's monolithic UL 1778 double-conversion UPS and the only model here with a published new-price curve

Toshiba G9000 Series, 100-2000 kVA is one of 22 UPS systems tracked in the SecondWatt catalogue, each with specifications, lead times and indicative secondary-market pricing.

Toshiba G9000 dossier: 100-2000 kVA, UL 1778 listed, up to 97% efficiency, new pricing from 312 to 397 USD per kVA, and a full used-unit inspection checklist.

Why it matters

A dealer-published 12 to 16 week lead time on a new 500 kVA G9000 sits against a market benchmark of 30 to 48 weeks for static UPS in the 500 to 1,500 kVA class. That 20 to 32 week schedule advantage is unusual in this category, where UPS is already the shortest-lead major electrical asset in a build. It also caps what a used G9000 can command, since the new alternative is not far away.

Who buys it

Data center operators, hospitals, industrial plants and public-sector buyers who specify a UL 1778 listed monolithic UPS and do not want an eco-mode transfer in the design. The G9000 also has an unusually active rental channel, with Global Power Supply running trailer-mounted G9000 units and CI Group listing rental systems, which is the classic origin of ex-fleet secondary stock.

Role in the data center

Facility-level primary UPS from a single 100 kVA cabinet to an 8-unit 4 MVA parallel bus, with external batteries and no eco-mode transfer in the design.

Key specifications

Pricing and availability

Trend: up New dealer pricing falls cleanly with frame size across the range: 397 USD per kVA at 160 kVA, 361 at 300 kVA and 312 at 1000 kVA, all now marked sold out. Within the Toshiba brand, a 2015 4400 80 kVA with bypass and two battery cabinets sold at roughly 350 USD per kVA while a 4200 80 kVA sold at roughly 97, a 3.6x spread driven by age, condition and battery inclusion. Lead time, new: 12-16 weeks at 500 kVA (dealer published), against a 30-48 week class benchmark. Lead time, used or refurbished: 1-4 weeks from dealer stock. Warranty, used: 1-year typical from refurbishment dealers.

Lifecycle and maintenance

Static UPS cabinets serve roughly 15 years, the figure Mitsubishi publishes directly alongside a lifecycle-parts-or-replace decision at 10-12 years. The wear items are documented: Eaton rates DC bus capacitors at 7 years of continuous duty and up to 10 under favorable conditions, while Vertiv field data gives 6 years for capacitors and 5-6 years or 40,000-50,000 hours for cooling fans. Batteries turn over far faster, at 3-5 years for sealed VRLA and 12-15 for flooded cells. Service life extension programs rebuild the power train inside the original shell, which is why cabinets routinely outlive their electronics.

Common failure points

• Battery strings — VRLA capacity fades below 80% of nameplate and takes the ride-through with it
• DC bus capacitors — Silent open-circuit loss, or a short that pops and sprays electrolyte across adjacent boards
• Cooling fans — Overheating transfers the load to bypass and leaves it unprotected
• Air filters and dust — Restricted airflow raises internal temperature and shortens capacitor life
• Static bypass switch — Failure to transfer strands the load during maintenance or overload
• Controls obsolescence — Discontinued display and logic boards turn a routine repair into a scavenger hunt

Inspection checklist

Battery age — sealed VRLA turns over at 3-5 years per Eaton lifecycle guidance; assume a full string past that Battery capacity — reject any string below 80% of nameplate capacity under IEEE 1188 practice Battery impedance — ohmic readings above 20% of the commissioning baseline condemn the cell Float voltage — verify 2.23-2.27 VPC at 25 degrees C; float current above 3x steady state flags thermal runaway Intercell connectors — thermal image every joint; a delta above 5 degrees C against neighbors triggers a capacity test DC bus capacitors — Eaton rates 7 years of continuous duty (10 optimal); Vertiv field data gives 6 years at 45,000-50,000 h Cooling fans — Vertiv field data gives 5-6 years or 40,000-50,000 hours; listen for bearing noise at the intake Air filters — pull every filter; a clogged element is the best single proxy for a cabinet that ran above 25 degrees C Load bank test — run 100% and 50% load bank steps; load banking is the de facto acceptance standard in this channel Static bypass — transfer to bypass and back under load 3 times; verify the SCR assembly and breaker interlocks Battery inclusion — get cells, cabinets and racks in writing; a battery package can reach 76% of a 30 kVA class deal Firmware and cards — verify current firmware and a working network card per Eaton's 11-point used-UPS guidance Lifecycle stage — check OEM support status; Mitsubishi's 4-stage table is the only dated public one in the category Documentation — manual, factory startup report and service history; Eaton flags 7-10 year units for capacitor work Removal conditions — verify rigging path, door widths and shutdown window; a 225 kVA cabinet runs 3,605-4,805 lb

Procurement channels

Toshiba's US dealer network (Global Power Supply, CI Group, Critical Power Warehouse, Quality Power Solutions, Toromont) sells new, refurbished and rental G9000 units. The rental fleets are the most likely source of ex-fleet secondary supply.

Regional notes

US 480 V builds carry UL and cUL 1778 listings. A separate 380/400/415 V series covers international markets at lower published efficiency, with full-load efficiency of 95.1% on the 400 V model.
