FAQ

Why rack-format three-phase UPS?

When the whole data hall is standardized on racks, keeping the UPS in the same format simplifies layout, scaling and service versus floor-standing towers.

What batteries does it use?

The 33ET is designed around external LiFePO4 packs — higher cycle life and one-third the weight of VRLA strings.
