Im seriously considering a Generac 7000 EXL model which will be tied
into my electrical panel. I just want it mainly for critical loads in
case of a power outage...like : the Furnace Motor (1/3 h.p.) , the
fridge, t.v., and some lights.
What is your opinion of the Generac brand ?? I can buy this model, new,
for $1318.00 delivered.
Lowes often has deals on Generac, a free transfer panel kit valued at
3-400. I bought a 7500 EXL at Lowes for 1200 with free Panel. A 7000 is
alot of power for a furnace and tv. A 7000 exl will power 2-3 houses.
Generac is noisy. The 7000 will weigh 260 lb. For quiet power look at
Honda or Yamaha or Kawasaki, Clean power on Inverter models, 1%
distortion, Generac Exl 6-7%, unregulated crap is 35% distortion.
Generac EXL are good for the money, get a free Transfer panel kit. Honda
are 2-2.5 x more in cost
Bought that exact same model in August. Brought it home, set it up and
ran it for about an hour with various power tools attached as loads.
During this testing it ran fine. Had a three pole disconnect panel
installed to connect to the house. Made up a 50 foot 10-4 cord set to
connect to the outside receptacle to feed the disconnect panel.
After checking everything twice, started it up, hooked it up, turned off
all the breakers on the disconnect panel, switched the disconnect panel
to the generator side and brought the circuits back on one at a time.
Everything was looking good. Fridge and freezer were running fine,
kicked in the oil fired furnace, no problems, cycled the 1 hp well pump
a couple of times and everything was working great. Shut off the furnace
which left only the fridge running at that point. Got out the volt meter
and checked the voltages on each leg while the fridge load was on it.
Had 122 volts on each. Looking good! After letting it run under load for
about 45 minutes the engine pitch suddenly changed. At first I thought
the fridge load had dropped out so I checked the output voltage again to
see what it was with no load on it. This time, the reading was 0 volts
- both legs.
Shut down everything and took he generator over my workshop and carried
out further tests. Everything was dead. Opened it up and looked for
obvious signs and smells of overheating/burning, loose connections, etc.
and found nothing.
A couple of days later, loaded it into the van and took it in to the
nearest Generac repair depot. Got it back a week and a half later. Turns
out that the stator had failed for no readily apparent reason. The
repair shop said that this occasionally happened on new sets and not to
be overly concerned. When I got it home, I fueled it up again, started
it up and ran the same tests as described above. This time I ran it for
2 1/2 hours under constant load and cycling various loads in and out.
The thing ran like a champ. Have had absolutely no problems with it
since. I run it every two weeks for about a half hour with my big shop
vac attached as a load (the only time my shop gets vacuumed out :) ).
Haven't had to use it under a real power loss condition yet but have
used it a few times for odd lobs around the property.
Basically, I'm quite happy with it. I especially like the 12 1/2 kw
surge capability. It is heavy (240 lbs) and is not all that easy to push
around on a soft surface such as grass. Also, I leave the idle-down
switch on the off position. When hooked into the house circuits it seems
to cause the engine to surge up and down continuously when there is only
a light load on it. It is also quite noisy but I suspect the noise will
be somewhat comforting especially during the winter when it's 30 below
and the grid power is down again. Just got to remember to keep a couple
of jerry-cans of gasoline around.
