My Heart Freedom 2500 Watt Inverter (12 VDC/110VAC w/charger) went under water
during Isabel. Fried everything and turned most of the guts into an amazing
mix of metalized dust/dirt/crud.
I bought it about five years ago along with a Heart Monitor/Remote Control. It
was a good, dependable unit.
I'm looking to replace it now and am looking for suggestions. Lots of cheapo's
out there. Saw a "Delco-Remy 2500 w/remote" at BJ's yesterday for $99.00.
Looks like one of the China clones.
I like the Charger/Equalizer feature of the Heart. I note that the Circuit
Board is not Conformal Coated for a marine environment. The Inverter will
eventually be moved onto the Boat so I need it to work.
Additional question: Has anyone coated the main Board and Contacts with
Conformal Coating to prevent moisture corrosion?

trace / xantrex comes to mind.

I've seen 2000w inverters as low as $80, and 3000w for $35. Frankly, I
haven't run across any 2500w inverters.
I have a 1500w, and lust for a 3000w because it produces nearly 30a. That's
enough to run 2hp motors or a small welding machine.
Marine rated inverters are a completely different kettle of fish. They are
costly, but yacht owners can afford them.
I bet in 10 years, 1000w sine wave inverters will be a cheap commodity. I
can't wait. Well, I suppose I have to wait. ;)

I own two Statpower inverters (250 watt and a 1500 watt), a Xantrex 1000
watt inverter (bought at Costco for $9), a Vector 400 watt Inverter (used
in my car for powering my laptop when I travel), and a Trace DR1524 (1500
watts at 24 volts).... all my inverters are Modified Sine Wave with 12 volt
inputs except the Trace1524... there is also an excellent inverter out there
that is a Pure Sine Wave, and has a low Idle current draw and a high surge
capability.... it is called an Exeltech and it is not too expensive, which
will probably be my next inverter...
Exeltech comes in two varieties, one is a stand along unit, and the other
variety is the Rack Mounted unit... I think all Exeltech inverters are Sine
Wave... The only negative thing about the Exeltech is that it only comes
with the 120 volt output (unless this has changed recently)... if you want a
240 volt output, then you will have to get two Trace Sine Wave inverters
which are synced to each other via a cable... these inverters are a bit
When I get my next inverter, it will be the Rack Mounted Exeltech, so that
additional 1000 watt modules can be plugged into the rack as needed (it can
handle up to 20, 1000 watt modules) ... you can even get a rack mounted
Oscilloscope that monitors the sine wave.... I have seen this oscilloscope
in action at the Solar Alternative Fair in Fredricksburg, Texas.... it is
neat to watch... and with the low power idle kit, the idle power usage is
reduced down to 9 wh....

Well, only if you insist on not having a bit of IRON hanging around.
The BEST (and the cheapest) way to do 240Vac from an inverter is to
feed a 2:1 Transformer on the 120Vac side and take 240Vac off the
other side. 3kw transformers in this class cost about $50US each,
and that is a whole bunch cheaper than doing twin SW Series Trace
Inverters Intertied. Works very well with Non-sinewave inverters as
well. I use transformers in my Powerhouse to do the reverse job.
Balancing 120Vac loads across my 240Vac gensets. Iron works best for
both these jobs and they are very efficent.
