Rob,
I'm also a bit of a technical misfit when it comes to electricity but the
following thought occurs to me -- the technical specs mean that is what it
can do, not what it must do.
I know in the area of sound that specs on amplifiers, speakers, etc. mean
that. I always bought above what I actually needed in the event I might
slip up and actually hit the limit. So, having 60 amp capacity doesn't
mean it'll be doing 60 amps.
In my mind the main thing to watch is the watts. 1000 watts is for wimps.
A hair dryer will eat that up as will a coffee maker or microwave without
even trying. Of course, if all you intend to run on AC from DC is your
computer, charging your smartphone, or watching a bit of TV not designed
for DC then 1000 watts works for a while.
I could be wrong, of course, but at least there's a target to shoot at.

Rob,
The specs all look good. I'm wondering: Are you going to run everything
on-board at 120 vac vs 240 vac? I thought you'd said something about
having had the Onan rewired for 240 vac, so I was surprised at the 120
vacoutput inverter. But not as surprised as I was by the
specification of
input current protection: 12 each 40A fuses!!!??? I guess they don't like
big fuses down there, huh?

G'day,
G'day,
Thanks for the comments! I'll respond to each commenter in order:
A,
Comment 1: What kind of battery pack are you going to run that inverter from?
Response: I'm hoping to run it off two Trojan 6 VDC golf cart batteries.
http://www.alcobatt.com.au/Editor/assets/trojan/golfspecs.pdf
Comment 2: 3000W will run a roof A/C or electric water heater with room to spare. But on two golf cart batteries it will only run
that load for a few minutes (maybe).
Response: The inverter will be used to run the microwave and one wall plug for our Keurig coffee machine, toaster, or sandwich
grill. That way we can prepare breakfast or lunch without having to start the generator and piss off our neighbors!
Comment 3: I think you will find that at lower loads the efficiency goes down. It might run your house pack down pretty quick, even
with low load.
Response: You're right! If I read the specs correctly it draws 300 amps at 3000 watts! I may have to go to two banks of two 6vdc
Trojans to be able to power the inverter.
Comment 4: My preference is to run each appliance from its own inverter, sized to the appliance.
Response: I don't have the specs for the microwave handy but IIRC it draws over 1000 watts when it first starts the cost difference
between a 1500 watt and 3000 watt inverter is negligible so I might as well buy the 3000 watt mode.
Comment 5: That way you can turn the inverter off when the appliance is off and not burn any juice in an idling inverter.
Response: The inverter would only be turned on when I want to use any of the appliances listed above. I can by a remote control with
a 25 foot cable and mount it in the galley.
Here's a link to the photos of the Xantrex inverter installation in Double Trouble. as shown in these series of photos:

Byron,
Comment 6: I'm also a bit of a technical misfit when it comes to electricity but the following thought occurs to me -- the technical
specs mean that is what it can do, not what it must do.
Response: Agreed
Comment 7: I know in the area of sound that specs on amplifiers, speakers, etc. mean that. I always bought above what I actually
needed in the event I might slip up and actually hit the limit. So, having 60 amp capacity doesn't mean it'll be doing 60 amps.
Response: Most people install a PD 9145 (45 amps) converter in the USA and it handles the DC power supply / battery charging
requirements. I installed a PD 9160 (60 amps) and its overkill.
Comment 8: In my mind the main thing to watch is the watts. 1000 watts is for wimps. A hair dryer will eat that up as will a coffee
maker or microwave without even trying. Of course, if all you intend to run on AC from DC is your computer, charging your
smartphone, or watching a bit of TV not designed for DC then 1000 watts works for a while.
Response: The TS-1000 is a confusing part number; the inverter is actually 3000 watts with a surge capacity of 6000 watts.
Dan,
Comment 9: keep in mind that with a small 45 amp charger you can use a 1kw portable generator to keep batteries up to snuff. If you
go with a larger one you will need a 2000 watt generator. AND, you might not care if you can plug in all the time or just use the
Onan.
Response The PO removed the Onan and installed a 6500 watt 240VAC / 50 Hz generator.
Comment 10: Before being totally solar sufficient I bought a 45 amp just for that reason.
Response: I will compare the size and cost of the 40 amp and 60 amp converters, I'd like to install it under the shelf under the
bathroom sink which is where I installed the PD9160 in Double Trouble.
Comment 11: Also, a 700 watt inverter will run most everything. Wont run a microwave or vacuum cleaner and you can't use a hair
dryer.
Response: As I noted in Comment 4 above the TS-3000 seems to be the "best fit." Helen and both use a hair dryer that consumes 0 amps
- a towel! ;-)
Ken,
Comment 12: The specs all look good. I'm wondering: Are you going to run everything on-board at 120 vac vs 240 vac? I thought
you'd said something about having had the Onan rewired for 240 vac, so I was surprised at the 120 vac output inverter.
Response: Oops! I should have noted that I would buy a TS-3000-212 (240 Vac / 50 Hz), the specs are in the fourth column from the
left.
Comment 13; But not as surprised as I was by the specification of input current protection: 12 each 40A fuses!!!??? I guess they
don't like big fuses down there, huh?
Response: Hmmm, you're right 12 fuses does seem strange. I will email Meanwell to clarify what 40*12 means.
Regards,
Rob M.
