I bought one of these Victron PSW inverters.

It has a remote switch that I wired to a switch near our tv and have been happy with it.


Interesting. Sort of priced midway between the bottom and the top. I'm looking into this more. They also have a 250 watt model for under $100.

It's just Mrs. SpeakEasy and me now (empty-nesters). But we can choose from among 7 grandchildren to drag along with us!

I have the 600W AIMS PSW in my off-road POPUP. It has two 120VAC outlets on it and I run an extension cord to two different locations in my POPUP, This unit is always ON...

Here is a drawing of my floor plan showing where this is located...

Having these two multi-socket drop cords does just fine for us when camping off grid and not having the regular 120VAC sockets activated...

Having the PURE SINE WAVE model eliminates the possibility of burning something up.. Some items will not run on MODIFIED SIGN WAVE types.

Made an interesting discovery as I've been researching this and following suggestions made by you guys. If you look at weight as an indicator of quality...

Bestek 300w......... 1.54 lb ($46)
Giandel 300w.........1.61 lb ($46)
Victron 375w..........6.6lb ($122)
GoPower 300w.......7.7lb. ($146)

So even though the GoPower is the "most expensive," it only costs $19 per pound, as compared to $30 per pound for the Bestek.

I do believe weight correlates with quality in this kind of product. Don't you?

Some have plastic casings and some have metal casings that affect their weights, but it is still what is inside that counts.

I’ve been happy with the Bestex brand but I don’t push their rated limits.

Most of the Bestex brand inverters are modified sine wave and the one that are pure sine wave do NOT maintain that sine wave as the load increases.

I am in the cry once crowd. Would look hard at GO Power, Morningstar and Victron in this inverter size class. Victron would probably be my choice. This company is customer focused, innovative, and not excessively expensive.

Yup. I ordered the Victron one. Glad I asked for your opinions, and feeling pretty satisfied that I made the best choice for my needs.

excellent. You're likely to never have to replace it.

At 300 watts I would say that how you plan to connect the inverter to the RV electrical is just as important as the inverter that you buy. If you plan on plugging into a dash mounted cigarette lighter type socket, you'll generally find that the wiring to the socket is sizes/fused for 10 amps DC at 12 volts. (it may be more but you should check that) Many RV's have 1 or more auxiliary sockets (provided by the coach builder) that is/are wired for 20 amps at 12 volts DC. If you buy a 300 watt inverter and load it up, it will try to draw up to 25 amps. Even more as the batteries discharge. See the problem? With lots of use at high loads, the socket will eventually overheat.

IMO, at more than 240 watts continuous, it's better to hard wire the inverter directly to the battery posts with terminals or at least use temporary spring loaded compression clamps rather than the cigarette lighter type battery socket if provided with the inverter.
