I have only had the P10 for a couple of weeks. When it arrived your customer support person strongly recommended that the P10 plug directly into the wall and then all of my components into the P10. No battery backup in that scheme. In South Florida we experience brief power interruptions quite frequently. Just had one minutes ago, bright sunny day, very little wind and zap on then off then back on in the blink of an eye. This is not unusual. I called Tripp Lite, who have a good reputation and they told me that all of the AC powered battery backups include sine wave and surge protection. Seems to me these things could interfere with the P10. Also, assuming there is a suitable battery backup available, should I size it for the actual load plus a 2x safety factor, or for the theoretical maximum load? Thanks.

A number of people use battery backups with their P10 and this is just fine. What you want is not the fancy double conversion type, but the simple UPS that kicks in when the power goes off, as most do. Tripp Lite makes good products and neither the surge protection nor the UPS will bother the P10 - as you might think - as long as the UPS is not always converting power.
Something like this would likely do the job if your original P10 load isn’t too great - and most aren’t. You can always go bigger, but it’s the battery backup part that limits it to 900 watts.
Having written this, there is a downside, but it’s not severe. The quality of incoming power has a small impact on the P10’s outgoing power. This is because the p10 is not perfect. These UPS have fixed power cords of poor quality as well as internal circuitry that’s not the best. So you’ll lose maybe 10% of the P10’s capabilities to improve sound. Having said that, even with this getup the improvement you will get over going straight into the wall is significant - and unmistakable.

The trouble with an UPS that is not Online type is that it might not be able to do a bumpless switchover within a half cycle and then the load might go down. It might be that since the P10 is not SMPS but a more conservative design before regenerating (if my understanding is correct) it might be robust enough to deal with this.
