KOHLER GENERATORS
Back-up (stand-by)
Generators can
be set-up to go on
as soon as an
electric outage
occurs, giving you
uninterrupted
electrical service.
There are several
ways which your
system can make the
transfer ranging
from automatically
making the transfer
providing you with
uninterrupted
service to manually
making the transfer
where there would be
an interruption of
service. How you
choose to
 make
the transfer depends
on you and your
needs.
Using only the
Generator as a Grid
Stand-by, to
come on if your
Utility Power fails.
You would want to
use a Transfer
Switch or an
Automatic Generator
Start Relay (AGSR)
which will allow you
to have electric
when there is a
problem with your
grid source.
When the switch
detects an outage it
turns on the
generator to provide
you with electric
and than shuts off
the generator once
your utility
electric is
restored. This
method gives you
basically
uninterrupted
service, meaning
that once your
electric source
stops (no electric)
the switch has to
turn on the
generator, the
generator in turn
has to stabilize
before it can send
electric to you.
Meaning that you
could be without
electric for up to a
minute or two.
If you have
equipment which need
to have no
interruption than
you may want to
consider using an
inverter in place of
the transfer switch.
Using the Generator
as a System Back-up,
to come on when
your system falls
below a certain
voltage and or when
there is no electric
from the Utility. In
this instance, your
system would include
a battery back-up
and your system
transfer would be
done by either an
Inverter or an
Automatic Generator
Start Relay.
Here, your main
source of electric
is the utility
company. When
you loose electric
from the grid, your
system switches to
the Inverter which
uses the batteries
to make your 120 VAC
electric. Once
your battery voltage
drops below a
certain voltage, the
Inverter or an AGSR
starts the
generator.
Once the batteries
reach a certain
voltage level or the
grid is back on
line, the generator
is shut off until it
may be required
again. With this
set-up, you could
incorporate Solar,
Wind and or
HydroElectric as
your main source of
electric, keeping
your batteries
charged and using
the inverter to
supply electric to
the house.
Using the Generator
as a Back-up for
your Solar, Wind and
or HydroElectric
System.
This example can be
used with or without
a Utility
connection.
Your main source of
electric comes from
your own power
plant, whether it be
solar, wind or
hydro. When
your system has
depleted your
batteries to a
certain level, your
Inverter or AGSR
turns on the
generator and once
the batteries are
filled to a certain
level, the generator
is shut down.
Some inverters will
see if the Utility
is available before
it starts the
generator.

When it comes to
back-up / stand-by
generators we
prefer the
stationary
generators as oppose
to the portable
generators for a
number of reasons.
Mainly because they
interface with both
solar systems and
with utility service
and they can be
started
automatically as
mentioned above.
However, sometimes
there are other
considerations one
must take into
account and for this
reason, I have
attached an article
by Bill Hoffman so
that you can make up
your own mind.
For Solar
Electric System
backup generators
we have found
that Kohler makes
the best on the
market. They
run on either
natural gas or
propane by just
making a few
internal adjustments
and can be started
automatic so that
there is no power
outage. They
are also the only
generator on the
market today, whose
warranty isn't void
if used with solar
applications.
For Solar
applications we
recommend either
the 8 or the 12
kilowatt models as
they are large
enough for most uses
yet small enough to
operate to conserve
on fuel consumption.
If you really
require a larger
generator please
contact us and
we will supply you
with OUR PRICEs and
sizes.
Our most popular
unit is the
Kohler 08RES that
puts out 8 kW with
an output of 110 and
220 volts. It comes
with a pre-heater as
does the 12RES for
those colder areas.
Both generators come
on its own platforms
which makes
installing them easy
as they can be
simply placed on a
bed of gravel.
The gravel is used
so that water can be
shed away form the
generator.
Our generator has
been in service
since 2004 and
replaced our earlier
units which were
Onans and before
that, a Generac. We
have been very happy
with our Kohler. In
2006 they replaced a
circuit board for
us, but as it turned
out the problem was
caused by some warn
linkage parts. It
has been our
experience that the
linkage parts do
need to be replaced
whenever they start
to show some ware.
Attached is a
copy of Kohler's
warranty which
does not mention
anything about or
against solar
applications.
Most other brands
will specifically
warn that if you use
their units in solar
applications that
you void their
warranty.
Kohler does require
that once you have
your generator
installed that it is
started by one of
their certified
personnel who will
activate your
warranty.
After reading the
below warranty you
should contact
Kohler to clarify
any additional
questions you may
still have.

Replacement Parts ---
Filters, Fuses, and Throttle Linkage Replacement Parts* for Kohler 8RES, 12RES, 15RES Generators
*Here's a helpful hint. We have found a that
sloppy throttle linkage can lead to generator malfunctions.
Symptoms may include over or under frequency shut downs as well as over
and under speed shut downs which can be easily fixed by replacing the
linkage part in question. We have made it part of our regular
maintenance inspection and replace the parts as soon as there is any
sign of ware.We recommend that you change your oil
and air filters as outlined in the maintenance schedule and that you
replace these three plastic linkage parts about ever five hundred to a
thousand hours to prevent a service call and to keep your
generator running smoothly.

Onan Propane Generators |
|
Although Onan makes a good generator, resently we are not
offering them until Onan upgrades their warranties to include generators
which are used for solar back-up.
Onan offers generators for use in motorhomes, utility trucks,
and crossc ountry haulers, and feels that it is okay to warranty this
type of use but does not offer their warranty for solar back-up
applications.
We keep this space available in hopes that Onan will someday
come around and make their policy solar friendly |

CHARGE AND GENERATOR START CONTROLS
Generator Start Control Module
The GSCM is a micro-processor based generator starting controller that
receives start commands from the 12 volt output from an Outback FX inverter
aux relay, a user supplied switch, an auxiliary relay in an inverter, a
voltage controlled relay, a timer or any user-supplied contact closure and
automatically controls a gas/propane or diesel powered generator or pump. It
is totally sealed for harsh environment operation.
The GSCM provides contact signal relays to start the engine and
disconnect the starter when a minimum generator frequency output is
measured. It monitors the generator operation, shutting it down if one of
several fault conditions is detected. LEDs are flashed to indicate the cause
of the shutdown. Manually resetting the GSCM removes the lockout and allows
the generator to restart if called.
The GSCM is powered by 12 to 24V DC from
a battery bank and will start generators for 12 to 48V systems.
For 48V
systems the GSCM must be powered by a 24V or less tap on the 48V battery
bank. The GSCM provides a 30 day exercise function which can be synchronized
with a photovoltaic input to only start each 30 day period at the beginning
of the solar charge day.
- Dimensions are 5.5" x 3.3" x 1.5"
2-year limited warranty.

Magnum AGS – RV Auto Generator Start
The Magnum AGS is compatible with most major generators, including Onan,
Powertech, Generac, and Weterbeke. Please check
with us for specific model compatibility. The Magnum Auto Generator Start
(AGS) is designed to automatically start your coach
generator based on low battery condition or the inside temperature of the
coach.
You can set the battery start voltage from 10-12 VDC or 20-22 VDC, the start
temperature from 65°-85°F, the run time from one
to five hours, and the quiet time with an easy-to-set clock. Auto
Gen Start settings do not interfere with the manual start / stop
operation of the generator. Just use any existing start / stop
switch in your coach.
Two models are available. The standalone version of the AGS
works well for installation and operation without an inverter.
The network version of the AGS allows operation of the AGS
via the ME Series remote panel.

Generator Start Control by Battery Voltage The Solar Converters GS2-AC automatically controls starting and stopping
of generators used as back-power sources in off-grid systems. It starts the
generator when battery voltage drops below the low set point. When the
battery gets to the high set point the GS-2 stops the generator.
Supports
2, 3 and 4 wire systems as well as advanced control systems. The set points
can be adjusted for 12, 24 or 48 volt battery systems. Circuitry can operate
between 10 and 63 volts DC. The generator may be remotely started by a
single pole switch or any dry contact closure.
A 5 second time delay on
voltage sensing prevents false triggering during motor starting surges.
Circuit uses less than 20 mA when not starting generator.
Optional
temperature sensor allows the voltage set points to be temperature
compensated.

IOTA Automatic Transfer Switches
Web
Site
Safely connect an inverter and an AC generator to the same house wiring.
These automatic transfer switches can be used with inverters that don't
have built-in transfer switch capability. If the generator is not
running, then the inverter is connected to the house wiring. When the
generator is started, the house wiring is automatically disconnected
from the inverter and connected to the generator. A time delay feature
allows the generator to warm up before the transfer takes place.
These transfer switches are
particularly useful in RV and Marine installations where both the hot
and neutral terminals must be switched. They can be used between an
inverter and a generator, between an inverter and shore power, or a
generator and shore power. Two transfer switches can be used if
switching between all three
 power sources is desired.
Indoor rated housings have conduit knockouts on all four sides.30A
and 50A units have a plastic housing and 100A units have a metal
housing.
