We ended up adding an Uninterrupted Power Supply (UPS) before each of our TV's and DVR's. Ours would only reboot about 50% of the time when switching between generator and inverter but as you say, it was annoying. Less than $40 each solved our problem https://smile.amazon.com/gp/product/B001985SWW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Whenever my generator starts while I'm on battery power my satilite receiver reboots and I have to wait to get the signal back. Aggrvating because everything else seems to switch without a blink.

I think it has to do with the efficient modern switching power supplies. Previously the old heavy transformer, diodes and large capacitors would carry the device as the power switch was made.

The OEM TS between shore cord and generator
Has a time delay before 'ON' to allow the generator to come up to speed and stabilize

When shutting down, the generator head will try to maintain voltage but it will drop, the TS will maintain/hold the contacts until the voltage has already dropped below the threshold needed for the modern power supplies in electronics to work
So the electronics are turned off power loss before the RV TS can switch over

As I keep messing around with this, I've isolated that really just the HD TV is turning off when switching back and forth from inverter to generator. The DVR and the satellite box stay on. Just looked up UPS's, I'll get one ordered and plug the TV into it, and might as well plug a couple other things into it as well. Should solve the problem, and cheaper than replacing the inverter.

Now I need the batteries to not run down so fast when the inverter is left on. I just ordered an SG200 battery monitor system, the newest one from Balmar, which gives both accurate SOC and SOH and has Bluetooth. See how good my battery bank is. Probably go from 4 to 6 batteries.

Thanks for the info and ideas.

Try visiting IRV2 they have a forum for National RVs .
Someone there will probably know the answer .

I don't think my Monaco Windsor does as you describe .
I suspect the manufacturers wired coaches up differently
resulting in behavior like yours .

Thanks.....will do.

Mine does the same thing and has done so since new. I can hear the switch activating when switching over. Monaco techs said it's a safety feature built into the coach and is normal....Dennis

You could be referring to the main transfer switch for the shore power, mine makes a click that can be heard. My understanding is that keeps shore power isolated from the on board power sources. There is also a transfer switch inside the inverter/charger. I found on the Freedom 438 that I have that the switch time is 25-40 ms. Like someone else here shared, my HD TV still clicks off but the other stuff I found is staying on. The newer pure sine wave Freedom 3012 has in internal transfer switch speed of only 10 ms which they say is fast enough to not disturb electronics. I have experience on a sailboat with the 3012 and none of the many electronics are disturbed when switching from inverter to genset and back, and the genset is on auto start. I was ready to buy a new 3012 inverter if needed, but using a UPS is a great idea and I have one ordered.

Please post what you get and how well it works.
