SW4024 is an excellent inverter, reliable, robust and if you can find another
stack them for 240 and will have no issues with the 3 HP table saw (assuming
batteries can handle that is). I run my whole home from a 13 year old pair of
them. </FONT></SPAN></DIV>

makes an excellent, robust, and reliable off-grid inverter. Available in 120 or
240 without stack. Stacking Magnums (for more power) is straightforward and the
user interface is very simple and intuitive. There is some different
hardware required for stacking. If a second SW4024 isn't an option then
this is what I would do. </FONT></SPAN></DIV>

<DIV><SPAN class=585101504-30102013><FONT face=Arial color=#0000ff size=2>I test
installed an Apollo unit last year. What a frustrating experience that was. It
requires a computer and a RS485 interface to program the most basic features to
make the unit usable. Nice when I was real remote and without Internet. That
alone makes it unappealing in my books. Seems they are a bit behind the rest of
the crowd. I'd not trust a marketing department claim it will start that
saw unless they can demonstrate it. (with of course some other loads on the
system - having to power down the house so one can work in the shop is hardly
usable). </FONT></SPAN></DIV>

<DIV><SPAN class=585101504-30102013><FONT face=Arial color=#0000ff
size=2>Outback units are common, though suffer from weak battery chargers and
power quality issues while under charge so for off-grid that involves any
significant generator charging they are not ideal. They are complex to program
and operate and end users report lots of frustration. </FONT></SPAN></DIV>

face="Times New Roman, Times, serif">Hello Wrenches,<BR><BR>I have an off-grid
client with a 24V system and an old Xantrex SW4024. He wants 240VAC capability
with enough oomph for sometimes making a cut with his 3 hp table saw without
starting the generator.<BR><BR>I am looking at Apollo, Magnum, and Outback
inverters. I'm most familiar with Outback. I have a couple of installations
out there with stacked 3.6 kW Outbacks.<BR><BR>However, the Apollo marketing
promises that their 3.2 kW inverter will start a 3 hp motor. Will it actually,
and is this a good idea even if it can?<BR><BR>I'd appreciate hearing about
your experiences with 240V Apollo units, stacked Magnums, and stacked
Outbacks. I know from experience that the Outbacks require some hundreds of
dollars of extra fittings and electronics to make a proper stacked
installation. How about Magnum? Any comments on reliability?<BR><BR>Many
