RE: Why won't 2000w inverter run 900w microwave?

Hi Sam,
Except, in this particular case the microwave is shutting down--but apparently not the inverter.
I agree that there are not enough amp-hours of battery bank.

RE: On demand hot water, to replace regular 6 gal tank unit

Hi Fsad,
I'd measure carefully before I ordered. I'm sure you can find dimensions on line.

RE: Breaktrough in solar

Hi westend,
Thanks for the funny video link. I had heard of it--but had never seen it. I laughed til my sides hurt.
Since many folks who boondock prefer to not run a genny, it may follow that they prefer to park in the shade. From that I'd pick panels that do well in leafy shade. Portable panels are an option--but storage space always seems to be at a premium.
Tilting, unless automatic, can be a pain if the camping style is, as mine is, over night stops. So long as the number of watts needed is met, the cheapest cost per watt panel that will fit may be the best choice. That said, it is better to have too many watts than not enough.
I get great results from my Unisolar panels and have never run out of power, since I upgraded the battery bank.
Every Rv'er needs to meet there own needs, so there is not a "cookie cutter" solution.
There is a good case to be made for having dual battery banks if you plan on nearly always boondocking. That way it is still possible to do saturation charging with no other source than the sun.

RE: Used versus new

Hi,
I would look for a unit no older than five years old. I'd put the difference in the purchase price into a repair fund. If you find a quality used unit a ten year life span (making the unit 15 years old) is quite possible.
Don't buy a unit that has indications of water damage.

RE: On demand hot water, to replace regular 6 gal tank unit

Hi,
I would look for a ten gallon unit instead of the "on demand" type.

RE: Why won't 2000w inverter run 900w microwave?

Hi,
I think the OP simply does not know the wire size. If so, he is in good company for most folks don't really want to know--until there is an issue.
What we do know:
The micro runs fine on shore power
The cable run is short enough (but we don't know the thickness)
Only two outlets are supposed to be powered (but how that is accomplished is unknown)
Two six volt batteries may be an inadequate power source for the demands of the load
Does anyone know if PSW output gets "dirty" when the DC supply is inadequate to the demand?

RE: Why won't 2000w inverter run 900w microwave?

Hi horton,
#10 wire on two feet for 12 volts @ 150 amps gives a voltage drop of 5.1% assuming the wire stays at 20 C (68 F). So 12 volts becomes 11.388
I'd never do that to wire. 1/0 would be my choice which brings the line loss to 0.5%

RE: Almost embarrassed to ask....

Hi Bumpy,
I'm at 103,000 kilometers (61,000 miles) and 9.5 years. No leaks. Class A is no assurance of zero roof leaks. I have the roof inspected every two years, for potential issues. No Eternabond needed yet. Just Dicor once.
Don't get me wrong--I think Class A's are quite wonderful. But, there is no question that wonderful comes at a higher price tag, one that is beyond my resources.
Since you have had a boat I'd not rule out a class C. Much cheaper to maintain. Less storage of course.
and the overhead either has leaked, is leaking, or will leak. take your pick.

Hi,
If you use foam make sure it is closed cell.

RE: Air Tabs Installed

Hi,
I put mine as close to the end of the RV as I could. I did have to trim one air tab on each side due to a clearance light.

RE: Breaktrough in solar

Hi
Doable and sensible are two different things. If you are rich enough that an RV is a toy, you can do what ever you want.
Unfortunately I'll never be in that position, so any modifications must address either safety concerns, make the RV more liveable or have a pay back. Modest solar appears to help battery life, so it qualifies. My rv works for a living as a portable hotel room.

Hi smk,
Oops I did not remember the tongue jack. What is that? three bolts and a #10 wire run?

RE: Air Tabs Installed

Hi,
It reduced the noise level dramatically. There is improved mileage when traveling with the wind, but very little difference when driving into the wind.
I did not have handling issues so I did not notice any difference in handling.

RE: Why won't 2000w inverter run 900w microwave?

Hi MP soldier,
Does the microwave work on shore power?
If so, is there room for more batteries? If not, then about the only solution that may work is to migrate to twin 12 volt marine jars.
Treat the workers with respect--they were only "doing as they were told".

RE: Breaktrough in solar

Hi,
The cells may be smaller--but what about the concentrator? Is it an integral part of the cell? If it is not, then the units would be useless in an RV.

Hi smk,
If you are correct the price for the not working too well installation is outrageously expensive.

RE: Breaktrough in solar

Hi Almot,
I wish I did not agree with you this time. Except I don't think it will be the great grand children. Things may fall apart a lot faster now that the C02 is at 400 ppm.

RE: Why won't 2000w inverter run 900w microwave?

Hi Almot,
The Xantrex Prowatt PSW 2000 watt unit is $355.00 from bestconverters.com
The OP's inverter looks suspiciously similar to the Prowatt, with just the display and outlets reversed.
I would tend to agree that a 2000 watt inverter for $200 would not likely be psw, unless it was purchased used.
I totally agree on the six volt batteries. They are being abused @ 140 amps of load.
