My personnel feeling is that it is not worth the savings of a couple of
hundred bucks to buy a modified sine wave (MSW) inverter and take the chance
that the devices I plug into it are not going to work or will work at least
than optimum, as in the case of a microwave. No one can tell you Bruce, if
your microwave or LCD TV or cell phone charger will work on a MSW inverter as
they are all different. Why take the chance? Just get a good sine wave
inverter.
In previous boats I have had a Mastervolt, an Outback and I am strongly
considering a Magnum MS2000 with a Magnum ME-RC w/ME-BMK Battery Monitor Kit
for my next boat which is under construction. Notice I do not list any
Xantrax products. I refuse to buy anything from them because of their past
business practices. Maybe they are OK now but they have lost me as a
potential customer.
Of the inverter/chargers I have used, I did not go back to Mastervolt because
of the size of their box and it had an annoying hum all the time. I think
they have all new models so you could look again. I really liked the Outback
and the support but the one thing that is turning me off now is that they
offer no easy way to turn off the charging function. I found many times I
would have liked to do that when it was necessary to cycle the AC input power
on & off. When this happened the charger would start charging in bulk mode
putting 14.4 volts at full current into the batteries. It didn't last long
but I did not think this was good on the batteries and it would have been good
to disable charging.
I am leaning towards the Magnum now for a couple of reasons and one is that I
can turn off the charger with a simple button push. I also like their remote
monitor which not only monitors the inverter/charger functions but also has a
battery monitor for checking on remaining capacity and voltages on up to 3
banks. Also the electrical guru at Fisheries Supply in Seattle, Tim Dies,
recommends it.

Subject: T&T: seeking advice about battery chargers/inverters
Happy New Year! I'm certain this has been discussed before so I may be
redirected to the archives (how do I search for a particular topic again?).
I
am in the market for an inverter. I already have a Xantrex Truecharge 40+
battery charger and, contrary to some negative comments noted here in the
past, and this is my second unit, have had good service. My question to the
group is then - what is the preference as to integrated chargers/inverters
versus separate units? The inverter would be used to power a LCD TV, a
microwave, coffeemaker, laptop and cellphone chargers, maybe the stove
occasionally, the usual. Are any of these of concern as far as possible
harm
from a modifies sine wave inverter? Space is not an issue but cost of
course,
is. Thanks in advance for the wisdom of the group.
