I have a place in a third-world country with 220V power and occasional power problems (not to mention lots of storms).

I have a decent quality 1500VA AVR which is somewhat similar to this: http://www.johsun.com/upload/img/20131217/Nippotec_Voltage_Stabilizer_SVC_1500VA.jpg

Currently, I use this to power all my computer equipment. It also has a built-in transformer so I can also use 110V on some of the outlets.

I have just purchased an 800VA APC UPS which also has AVR.

Assuming that I want to use the UPS for my computer, what would be the correct way to chain these items? I feel like the stand-alone AVR is higher quality in terms of the AVR function and more capable, but I'm not sure if chaining two AVR capable devices is a bad idea? Should i use the UPS alone?

Or, if I should chain them, should it be:

AVR -> UPS : This way the AVR protects the UPS. The downside is that anything that requires 110V won't be on the battery. I could always put a standalone transformer on one of the UPS outlets I guess (or is that a bad idea as well?)

UPS -> AVR : This gives me the advantage of being able to use the regulated 110V outlets as well.

I know it is bad to connect UPS in series, but what is the bad part of connecting AVRs in series?

For the technical hazards of series linking of these type devices, you'll have to contact westom.
As for the APC 800VA with AVR...
"Connect the UPS power cable directly to a wall outlet.
Do not use surge protectors or extension cords."

If I was to use both together I'd probably plug the UPS in the AVR but there's very little reason to do it. I'd probably stick to just the UPS. Stand alone AVRs are nice but really don't serve that much purpose as any equipment worth protecting with an AVR should probably be on a UPS anyway. An AVR wont protect you against brownouts or 1+ second outages. Those are the ones that are the most damaging to equipment.
