UPS for ReadyNAS 6 + ReadyNAS Duo

i have an APC BR1500G UPS that protects just a recently acquired Pro 6 and a 2 1/2 year old NVX. The Pro 6 has basically the same PSU as your Pioneer, but your Pioneer will draw more because of the drives (I have 2x3TB Hitachi Green and 2x1TB WD Red Label drives). The NVX should have a slightly higher power load than your Duo because of it's drives (2x3TB Hitachi Green and 2x1TB Seagate 7200RPM drives). The total load according to the front panel display is 116W or 13% of the capacity and has an estimated run time of 48 minutes. So, I would estimate that a 700W unit would provide less than 24min run time even without the laptop. The 1350W unit would provide about 40 minutes. But, again, the purpose of the connection is the orderly shut down of the NAS units. I have my UPS connected to the NVX (backup unit) and the Pro 6 monitors it over the network.

I have two older 1250 watt UPS units (one on the entertainment system to avoid resets) and one that powers the PC, monitor, router and switch. I was going with a BR1350G until I got the detailed specs of the BR1350G and BR1500G off the APC website and discovered that I can get a 1500 watt battery pack (BR24BPG) that plugs into the back of the BR1500G and is controlled by it and extends the run time. The battery pack will not connect to the BR1350G, nor will it connect to the BackUps XS BX1500G. In the US on Amazon the BX1500G is $3 less expensive than the BR1500G and except for the external battery pack plug has virtually the same specs. I wanted the possibility of future expansion.

Update: this post has typos in the use of Watts and VA. In the paragraph above 1250 watt UPS s/b 1250 VA UPS. In the first paragraph 700W should be 750VA and 1350W should be 1350VA. I have left the typos in place because a following post refers to this one and corrects most of the errors.
