Very Easy Setup
This is NOT a stand-alone UPS. You will need a "master" unit, but you probably already know this. I Added this unit to a APC Smart-UPS XL Modular 1500VA. Just remove from packaging and connect the cable into your existing configuration. Done. There appears to be no auto-detect feature for this hardware, so I had to run a battery load test to prove it was working (don't like to wear the batteries like that but calibration was necessary to know what my expected runtime would be). This unit more than doubles the battery time of an existing primary 1500VA unit. It is very, very heavy. It weighs over 120 pounds. It will require at least two people for installation in a rack, but that kind of battery power isn't going to be light. Shipping is through a freight service, NOT UPS or FedEx. Detailed package tracking is not available and they contacted me to arrange a day for delivery (between 10 and 4). I recommend this to anyone who needs 24/7 uptime but cannot use a generator for long-term backup power.
