Question about house type audio receivers

[rusty]

We are thinking about putting a house type audio receiver in our 15. When the 120 volt switches between shore power and inverter power there is always a momentary loss of power. Will this cause a problem to the audio system. If we plug in everyday on a trip that loss will be twice a day.

I don't know about your radio, but our TV has been handling the switch fine for several years now. We don't have Dish any longer, but the dish recver used to be fine switching all the time too and ours is not a Pure sine wave inverter, just an old Heart.

The receiver will turn off for an instant and then turn on again.  It's various feature sets will determine what this means - it means nothing to the basic function, since such receivers are designed for momentary loss of power, but it might cause pre-sets to be lost, a clock function to need to be reset, and so on.  My home receivers don't have preset radio frequencies, but some might - if they do they probably have a battery or similar memory support so you don't lose everything with a power outage.

I always turn our Bose system off, just a habit for me power changes probably would have no ill affects on it but I don't chance it, the repair places hold a gun to your head when repairing it BTDT. They don't seem to like any kind of spike we have Marantz in the house if it gets a spike you can kiss $300.00 good by

It depends how fast the switch is.

Most electronics run on DC current that is transformed / rectified from the 120AC, they use filtering capacitors to clean the DC power, those capacitors will act as a little lifeboat of sorts during the switch over.  As long as it's fast enough .1 to .3 seconds I'd say, you'll be fine.  I've run mine with a few automatic transfer switches, all my computers, tvs and receivers have been fine with it.

Thank You all. I did not think about the TV. I guess I have been doing it to the TV for years. The only thing is with the TV I always have it off when I switch over. I can do the same with the receiver.

Thank You Wayne

Buy a good ups  one that is on all the time not one that switches.  They are a lot cheaper than replacing electronic equipment.

Helps when you get power surges also when on shore power.

This is good cheap insurance in general.

I have some pretty nice Yamaha stuff, but most of my outlets are 100% 24/7 fed off of a sub-panel that is powered by my inverter output.
They never know if I'm on the pole or running my generator.

We up graded our tvs about a year ago with Vizio TV'S and it will drive you crazy having to reprogram the darned thing every time you change locations .There is no fast track either!!

I also agree.   A computer UPS doesn't cost much, and as long as you change out its gelcell 7aH battery every two or three years they'll be ideal.   You can even get 9aH batteries now of the same size for a slightly longer run time.   I plan on using a UPS for my wonderful old Quad 33/303 amps that are too good to not use in the bus!

I was going to suggest a battery backup as well. One caution though, as I've found that some battery backup packs don't work on an inverter and/or don't work on an inverter that isn't PSW.

Last summer I tried a battery backup on our flat screen TV, and it would not take a charge from the inverter at all. It worked well on generator or shore power, but not on inverter. Could never figure out exactly why since the only inverter we had at the time was not PSW, but that was my hunch.

[rusty]

Good to hear from you Ned. Thank you all for the advice. I will be using a battery backup system makes perfect sense.

My microwave is fed from an inverter circuit, but it still loses power for a brief second when the inverter transfers to shore power.  It doesn't seem to hurt it.

Rusty -

I'm old-school when it comes to transferring from shore power to the generator or vice versa.

We just turn off all the a/c circuits at the main panel, then turn them back on once the power comes back online.

We don't have an inverter on board at this time, but will be adding one after we install some solar.

The only thing we have to reprogram is the clock on the convection microwave, which takes what, 30 seconds or so?

Our coach's "sound system" is simply a 12vdc Kenwood AM/FM/XM/CD head unit purchased from an automotive stereo shop.

The TV and Dish box are usually off during the day when we're rolling along, so it's not an issue for them, as they're not normally turned on until after dinner anyway.

FWIW & HTH. . .
