Sine wave UPS instead of inverter

[dtfeld]

Was thinking about a sine wave UPS as a power source for my TVs and outlets. A 1500VA sinewave UPS is $200. Most have the ability to utilize external battery bank, or in my case the house battery.

Seems like a reasonable way to get a small amount of AC power onboard at reasonable cost. However, I doubt it would meet the ABYC code. Or would it?

UPS contains an inverter + batteries + switching electronics. At that price point, its doubtful the inverter (the only part you really need) is of very high quality.

By far, your best bang for buck if you just care about the TV, is to get a TV that works on 12VDC. Many utilize a 12VDC "brick" which you can just snip off and then wire the TV directly up to the boat's DC. That would be much more efficient (read less battery drain)

I did this with my TV, my Android TV box, and a Sony DVD player and wired it all through an AC relay such that on loss of AC, the devices are switched over to 12VDC automatically, much like a dual-voltage refrigerator.

I cant imagine not running the generator on a 410. The fridge , the freezer all suck battery life. Run the genset.. ITs needs to run .

We run it but I'm looking for a silent option for a quiet morning on the hook or when in don't want the noise and vibration. The diesel 410 couldnt fit a sound shield and ours probably needs new vibration isolators

How are you planning to connect it to your outlets?

My thought is to plug it into an outlet for charging off gen/ shorepower, but the only thing connecting to the ups would be 2 tvs. Probably rarely run both at the same time.

I have room in a cubby between radar arch and the door, so the tvs would plug directly in to the ups, likely not even need an extension cord.
