Courtesy of an offer earlier in the week, we have just purchased two fully redundant 40kva UPSs. They are Digital Energy™ SitePro® UPS's and came at a brilliant price.
While they are not as large as we would have liked, they are fully interlinked and run master-master for complete resilience.
Unfortunately we've had to delay the shipping as the previous premises fell through as I guess you've already read but at least they are ready to ship and as soon as we've moved them to NI, we will order up a complete set of batteries
