Hi Guys...I'd steer away from inverters since they soak up a lot of
power. You might want to look at some solar stuff with some of the AGM
batteries Marlon mentioned in another thread. Run everything @ 24V is
good that way you don't need any dc-dc converters.

You might want something like an inverter (Xantrex for example) which
includes a DC to AC inverter, battery charger, and automatic transfer
switch. Add the batteries and you're done.

Thank you,
That is very good advice. After some research, I'm leaning toward a
UPS.
A pair of good AGM batteries and charge controller will cost less
and be far less maintainence. Then I'd just run the CMM off the
batteries @ 24VDC.
Thanks again
Jerry

Subject: Re: [WISPA] Small auto start generator
Small generators do not auto start very reliably.
When cold or dampness causes hard starting the starter can overheat
and
burn out. Generally you need an electric choke to start gas engines,
propane can "flood" and need to rest before trying again, diesel can
be
REAL hard to start when cold. Auto starters can not adapt to changing
conditions.
Our best generator is a Propane Ford inline 6 cyl. 25 KW 3 phase.
(1955
Model)
The monitor cranks for 1 min then rests and tries 3 times.
Everything is
adjustable. It knows to stop cranking when it sees AC voltage from the
Gen. so the motor over runs the starter for just a few seconds. Only a
huge starter motor can take this abuse and last unattended.
You may be money ahead to find out why the existing generator is not
starting and get it fixed.

Any recommendations on a small auto-start generator? We only need
to power a CMMmicro - ~100watts.
Thanks
