||Generators are one of the
necessary pieces of equipment found in most off-grid solar
installations. These units are also useful for doing emergency
power in residential situations where the grid power infrequently
If the power failing is a frequent problem then a battery-backup inverter
standby power system is a better investment because it will provide uninterruptible
power during the outage. Usually any medium to large scale off-grid system
cannot make it through the winter on solar alone and requires some form
of supplementary power. This is where generators come in handy and some
modern inverters will even automatically start the generator if the batteries
get too low.
As far as types of generators there are mainly low speed (1850 rpm) and
high speed (3700 rpm) units which run on a variety of fuels. The high
speed units are noisier and don’t last as long. The low-speed units
are more expensive.
The ones that run on gasoline are all high speed units and range from
the cheap throw-aways like the Costco models and the Coleman’s
ranging up to the Honda units and similar ones that run on either gas
or propane/ natural gas.
The next step up are the units that run on strictly propane or natural
gas. These are usually also high speed, tend to be clean burning and
are available in industrial versions which can sometimes be found in
the low speed models.
The most industrial and long-living are the diesel powered units. These
are the most durable and expensive of the range of generators. These
typically are low speed and are much quieter and have a longer lifespan.
They can be either air-cooled or water cooled though the water-cooled
units are most common in anything over 5 or 6 KW.
Bio-diesel and straight veggie oil
One advantage to diesel units is their ability to run on bio-diesel which
is fuel made from either virgin or recycled vegetable oil. It pollutes
less, does a better job of lubricating the motor and is completely renewable.
Its even possible to convert the diesel generator to run on straight
vegetable oil which can mean free fuel if a person recycles their own
oil from the home or from restaurants.
Here at Land and Sea Solar, all our vehicles are fueled by bio-diesel
with straight vegetable oil conversion planned for the near future. We
support this technology for its sustainability and offer a number of
generators that run on bio-diesel. Contact us for more info.
