Re: T&T: Water heaters
We have had very good luck with the Raritan 12 gallon. We changed the
internal anode after 4 years and it still had at least an other year
on it.

I've been to www.theinverterstore.com and have been looking at the AIMS
units.
Intended usage: small 2 cubic foot AC refrigerator and running a laptop to
watch a DVD. Otherwise, perhaps a small fan. Think an auxillary to the DC
side versus powering the entire boat...
So, I'm looking at the 800 watt draws .4
1000 draws .6
and there are two 1250's that draw .5
I'm vacillating between the 800 watt and the 1250 -- the $129 one versus the
$99.
Pure sine wave is not an option, nor required. No television since 1993, so
the likelihood of purchasing same is rather remote.
Is there a reason why an AIMS should be avoided? Is there a reason why I
should spend $130 versus $100 for the 1250 unit, or would 800 be a good
choice. We cook with propane (no microwave)
House bank is 300 amps. Alternator on the engine and an Air Breeze wind
generator provide charging.
We purchased two AIMS last year, one pure sine, installed and have had no
complaints. Pricing was right, and we called before purchasing, decent
advice offered. Very helpful. Have not had to use customer service yet, but
it seems to be a small outfit, and I would assume the same people that we
spoke to.
The units are very quiet. We mounted them under the stairs to the lower
cabin and they cannot be heard. We would recommend them at this point (going
on our second season). Good luck, Laura

I would re-think this if I were you. Contrary to popular belief, modern
televisions and, in fact, many consumer electronics, are perfectly happy
with MSW, due to the type of power supplies they use. However,
induction motors such as the one in the 120-vac refrigerator you propose
to run really want true sine wave power. (Some more sophisticated
refrigerators, with line monitoring electronics, will refuse to run
altogether on MSW power.)
The fridge will probably work on MSW, misleading you to believe that all
is well. But the motor will constantly fight the too-rapid voltage
change, causing excessive heating in the motor. This will have the
effect of (1) reducing the fridge's efficiency, thus requiring more
battery capacity to run it and (2) ultimately reducing the life of the
unit. Also, you'll need a larger inverter than you'd otherwise think
because of the additional efficiency loss.
I would recommend you either go with a true sine wave inverter, or a DC
fridge. Alternatively, call the fridge a throw-away and add 20%-30% to
your power consumption estimate and your required battery capacity.
FWIW.
