looking for quiet 300 watt inverter

I will also recommend the Morningstar unit. It has no fan so makes no noise. It is very solidly build with a huge heat sink and large terminals. It's designed to be hardwired and has provisions for a remote switch.

My GoPower 300w sine wave is generally silent with no fan running the tv/dvd/net book and charging phones etc. Only time the fan runs is when running the 300w fridge.

Perfectly silent would be Morningstar as it has no fan.

I recently acquired a 400 watt Wagan pure sine wave. Compact design, the fan does not become audible until it is asked for 175 watts or so and when it does it is no where near as loud as the fan on my 800watt Comeman MSW inverter which also has twice the standby draw, and it basically now goes unused.

I use a samplex occasionally, and have never thought it was excessively loud.
Also a morningstar suresine operates silently.

At 300 watts I think it would be hard to find an inverter that was not Mechanically quite.. Eletroincally a TRUE SINE WAVE is best.

Suggestion: Mount the inverter in an outside compartment next to the one the batteries are in (or if the batteries are on the tong of a trailer, just behind the tong) this way the whisper fan is OUTSIDE the living space..

Then run 120 volt wires from there to the TV.

Now the "electronically" comment.

MSW inverters use stair steps as their wave form.. If you ever visit a farm where their is a set of stairs going over a fence.. .These stairs are called a Stile. That is also the name for a pile of dung.

And the wave form of an MSW inverter.. This generates electronic noise and depending on how well it is filtered it can go all the way up to microwae (There is a piece of electronic test gear that does just this on purpose by the way,, I built one once).

A TRUE sine wave inverter, however, Sings as sweet and pure a note as my daughter's flute can make.. NO noise whatsoever. Just pure 60Hz. (That is between an A$ and a B, the 14th and 15th keys on a piano counting both white and black keys).

I added my small wattage INVERTER with associated fuse block inside a cabinet which is as close as I can get to the battery bank switch and still be inside my POPUP trailer. Then I run 120VAC HD Extension cord with multiple receptacle head to the home entertainment and table near bedroom area. All extension cords are not visible and run behind cabinets or along the walls inside wiremode cable management items from LOWES.

Installing the INVERTER in this fashion keeps the noise down on the INVERTER if a fan is involved. Using larger 4AWG 12VDC cables direct connected to the battery bank insures excellent performance of the INVERTER.

We normally need about 300watts of 120VAC to run all the things we want to have on when camping off the power grid. My INVERTER is a AIMS 600WATT PURE SINE WAVE model from AMAZON $149...

We use a 400 watt unit. When it is steadily powering a TV of around 50 watts, the fan does not come on. If you add a battery charger for the computer, it usually did. Judging from that, most will run up to 20% without the need for the internal fan.

Punctuation please!! On top of the lack of detail, it's not easy to decipher 3 run-on sentences.

Define quiet? Are you looking for one without a fan, or one that doesn't generate trash?
