Hi Paul and All, I've done cost effective RE
offgrid for 45 yrs now replacing diesel generators, not that hard or expensive
if done right.You can buy a solar system kit or parts online for under $1/wt
grid tie too. Then hire a local electrician to permit, do what you don't want
to. For offgrid you need 2 sources of power which for me was
either small wind or tidal I produced in the 80s plus an engine preferably run
on RE fuel, normally an existing diesel run on used filtered veg oil, B-100.
This engine ran a DC generator and fast charged the battery at 200+ amps
cutting run time and fuel use as run at it's most efficient RPM/load.
Another engine, fuel choice is go cart racing motors can be set up for
ethanol, methanol, butanol, synfuels or other gasoline range RE fuel.
Not sure why people don't still use lead as so much cheaper and all the
equipment is geared to lead. I don't use Volt modules for storage because
there is no equipment for lithium yet in the US. I only use about
.5 day of lead and rarely have to use the generator with wind, solar. Tidal
happened 2-4x/day so even less battery needed. By the time you
need a new pack in 5-7 yrs on golf cart batteries, lithium will have dropped
in price to reasonable, viable. If up north the generator
becomes a CHP unit providing both power and heat done with a water
cooled/marine diesel run on b-100, used veg oil again fast charging batteries.
Those in windy areas should consider a marine/boat wind
generator or an 'axialflux wind generator' you can build yourself or buy.
parts or finished. Maybe start with some PV panels, some used
EV lead batteries, I'm using the best from an EV pack I sold Volt modules to
replace, with an inverter and run parts of your home with. Or
some panels with APS microinverters that if you put on a plug, you need no or
lesser permits to go grid tie. Now PV prices have dropped I'll likely start
using these to make plug and play systems to sell at about $1.25/wt, would have
been $1/wt with tariffs as the only way to get off FFs is put in the equipment
to replace FFs. By driving down the price makes that happen faster. I hope
many copy this. Charging an EV from solar is fair easy, cheap if
you can tap the DC port, you can charge directly with just a timer and a higher
than battery voltage solar output. With panels under $.40/wt well shopped 2kw
of solar is about $1k. And could be portable and left at work to charge while
you work, even shade the car as a carport. Or a lower voltage
solar with an upverter to the EV pack charging voltage with a max voltage cut
off. All that is needed is how to signal the DC port to turn on so it can be
charged. Anyone know how it is done or where the specs are?
