How a three phase double conversion UPS carries the load, and where the bypass sits.
The orderable configurations we supply and service:
| Model | Rating | Phase / Voltage | Part number | Status |
|---|---|---|---|---|
| Mitsubishi SUMMIT Series 500kVA | 500 kW | 3ph in/out 480V | · | Current |
| Mitsubishi SUMMIT Series 750kVA | 750 kW | 3ph in/out 480V | · | Current |
The SUMMIT Series is Mitsubishi's silicon-carbide (SiC) UPS, 500 and 750 kVA at 480 V, true online double conversion, unity power factor, up to 98% efficiency, and listed as the most efficient UPS on ENERGY STAR when tested in VFI mode. Its efficiency curve is flat across the load range, so it doesn't need an eco/standby mode to be efficient. SiC's wide bandgap (3.25 eV vs silicon's 1.11 eV) cuts losses sharply, Mitsubishi's own white paper documents a step from ~97% (silicon IGBT, 3-level) to 98.6% with SiC, roughly 70% lower semiconductor losses and ~39% less heat at full load. 65 or 100 kAIC, 1.1:1 generator, lithium-ion or VRLA.
UScellular replaced four aging UPS with SUMMIT units across a 48,000 sq ft data-centre/lab site and reported efficiency rising from 75 to 78% to 97.9 to 98%, with the utility committing over $300k in rebates for choosing the most efficient UPS and payback in just over two years. The install was compressed from a 12-week, one-at-a-time plan to a 4-week A/B-side approach with no downtime. Another operator, DC BLOX, deployed five 500 kVA SUMMIT units with lithium-ion.

Battery strings and cabinets depend on the configuration and runtime. Replacement batteries for the Mitsubishi Electric SUMMIT Series are matched by block type and cabinet.
We service the Mitsubishi Electric SUMMIT Series across Canada: preventive maintenance, battery replacement and emergency repair, including units the manufacturer no longer supports. We are a Canadian UPS service and supply provider, working on three-phase systems since 2012.
Repairs on running and out-of-warranty units are handled under Mitsubishi Electric SUMMIT Series service and repairs.
We engineer the solution: load and growth analysis, redundancy (N, N+1, 2N), runtime and battery sizing, paralleling and switchgear, and custom configurations where the standard catalogue doesn't fit. Because we supply every major brand, the SUMMIT Series is one option we weigh on its merits, not the only answer.
