I use two Honda EU2000 generators to power my trailer. At times when the AC goes on the power to the trailer the power drops and the TV goes out. If we happen to be watching Netflix or something similar it takes several minutes to get back where we were. I've added a hard start capacitor to the AC but that didn't fix it. I'm wondering if a UPS like you would used for power failure for a computer would work or if anyone had any other suggestions?

I've had many a power problem with my Directv receiver, and it takes almost 7 minutes to reboot. I've solved that by putting it on inverter power.

Is ECO mode on or off?A UPS for the tele will solve your issue but not fix the problem. A soft start module may help if the hard start capacitor didn't.

a UPS for tv. pc. dvd player, everything involved with entertainmentshould keep it from dropping outmy RV is a UPS, all electronics our powered via inverter from my AGM battery banka/c MW, generator on /off nothing resetsthe result is the same, dedicated inverter attached to rv batteriesor dedicated UPS, TV , sat box, dvd, PC, internet etcstay on

A UPS will keep everything connected to it powered up during a power interruption, up to the length of time the battery can support that load. I used to have a UPS connected to our home TV, satellite receiver, and sound system as power interruptions were not uncommon. It died a couple years ago and I have not replaced it even though our semi rural area still has the power issues.An inverter is s good idea if you can reasonably isolate that circuit or pull a new one. And knowing it will be pulling from your coach battery and possibly draining it if left too long.

Turning it off helps but then I give up a lot of the advantages of the generators. Will look into a soft start module.

NO not near the TV

the inverter goes near the batteries, then a new 120v circuit aka romex, ext cord etc..
is run to the area near the TV
a power strip is plugged in, and everything needed is plugged into the power strip

short run for 12v to inverter
long run for the new 120v circuit from the inveter

Oh my. That sounds like a major task. Hiding wires, making holes and pulling apart walls. Will I not be able to accomplished rhe same thing using one of those 50 dollar 300 watt inverters plugged into the 12 volt cigarette lighter socket that already by my tv? It's on the same plate where the antenna screws in so I'm kind of wondering if that's not what it was wired for.

Might just be easiest to get a ups or live with it the way it is.

Yes, a UPS is your most reasonably priced solution. I've used an APC on my entertainment equipment at home for many years to protect it from transients and brownouts.

I have this strange nagging doubt. One that has a pseudo sine wave from an el cheapo inverter looking like something out of a Salvador Dali painting.

When I had Xantex in motorhome, I could pull shore plug and the TV would not even blink.

Trying to think through this in my head. How would I go about doing this? I would need to get 12 volt near the tv?

Inverter/chargers do have automatic switch-over.
You put the box close to battery to avoid long cables, hook up shore power to it on one end and RV 120 fuse box to the other end.
This makes "set and forget" setup.
Each time you plug the shore power, after few seconds the unit will switch over and will automatically top up the batteries.
When shore power dies, the switch in nanosecond switches to inverter power.
This way you have uninterrupted 120V no matter what as long as batteries hold charge.
The system also helps in starting AC having small generator.
That would take good battery bank and bigger unit, but you start AC on inverter power and once it is running - let it switch to generator power, thus avoiding the hassle of hard AC starting on generator.
Unlike generators - inverters have huge peak power ratings.

Something like this?

BESTEK 300W Power Inverter DC 12V to 110V AC Car Inverter with 4.2A Dual USB Car Adapter https://www.amazon.com/dp/B004MDXS0U/ref=cm_sw_r_cp_tai_GqTzzb1CG2ZME

I do have a plug for this behind the tv. It's on the same plate as the push button for the antenna. Maybe that's what it's for?

As long as I only run the tv when the trailer is parked to 110 should the batteries be charging as fast as the tv is depleting them?

300W is really small but fairly common. Personally I wouldn't go smaller than that. But as mentioned above, an inverter in the RV serves this exact purpose. A few Lowe's stores still have 300W PSW inverters on clearance for $38. That way you're also not buying yourself another future battery changeout

x2 ... something in the $35-50 range should do nicely for the OP.

Attention: Be aware that UPS's inverters are MSW, not pure sine wave, (at least all the inexpensive ones I know about are) and your entertainment system may or may not be happy with an MSW power supply.
