Power shuts off with Monster controller

[PaulD]

Recently set up a small home theather in my new house and I included a Monster Power electrical power controller to filter and control power to all my components. Seems like the electrical power into my house has a high line voltage level around 125VAC+ early in the mornings (based on voltage reading on power controller) until around 9AM and then settles down to 115 to 122VAC the rest of the day. When voltage exceeds 125VAC, my power controller cycles the power off when it hits 125VAC then back on when it drops below 125. Not good for my components plus wife is very unhappy about it.

Have not called power company yet but that is my next step to see what they say.

Anyone else experienceing this behavior with the power grid? How did you deal with it?

My line voltage is also often high. I use a UPS, so when the voltage is high it just shifts to battery. You could also go with a true online UPS that will always condition the power without having to go to battery, but they are more expensive. I think a UPS provides all the benefits of a power conditioner, and then some. I bought mine from refurbups.com and it has served me well for several years.

I talked to my local elec company. They monitor and control the VAC from 113 to 126. My Monster Power unit (HTS5100MKII) kills power output to devices at 125. I talked to Monster and they said there is no way I can modify the 125 limit other than to step up to their AVS2000 ($1500) unit which regulates any input level VAC into 120VAC output. As a result, both say their system is operating as designed.

If your UPS approach works to keep my Power Controller operational, I would be interested to know how you do that. Do you just plug your power conditioner directly into UPS? Not sure I understand how that will fix my problem.

I have used a few UPS's which switch to Battery at preset (high or Low) voltage points. So you set these points if adjustable just inside your threshold, which would switch from AC passing through the UPS to the Load to the battery generating your AC and keeping it stable at ~120 VAC. The problem with this is I do not know if it still charges the system batteries during this time and you have a large window when it goes high which may discharge the battery if it doesn't maintain the battery voltage during the high period. Also another note is most UPS's will beep during this period, be sure to look for one that you can disable.
