[RE-wrenches] cogeneration

[Mark Dickson]

Have any of you had any experience or heard of experiences with the
residential cogeneration systems such as the Freewatt?  Sounded like there
was a lot of potential a few years back, but have heard little since.  Any
reason you couldn't tie one into an off-grid Sunny Island system?

 

Best regards,

Jeff, I greatly appreciate your offer to help us think through putting a
system together in Haiti. For some time we will be prioritizing the loads
not so much for the orphanage but for the doc and his wife. They are like so
many who buy into a project before processing that they are the ones needing
to modify their lifestyles..one of their priorities at our last meeting was
air conditioning. So it is going to take a reality check on equipment costs
for them to come to grips with actually living there. Even then these people
might have enough money to stick out as the Cadillac in a barrio. As we get
closer to a list of indispensable loads (even at that you'll probably have a
better idea of what can be bought in Haiti), then we'll know what size
battery bank, inverter, etc and I would like to get back to you on the
hardware and other design considerations that might be unique to Haiti.

Hi Bill,

If you want to contact me offline, we can refer you to a local dealer in
Port au Prince who ussually has Outback and Rolls products in stock and I
believe he currently has some Solarworlds as well.  For a one-off project
you're probably on the right track.  Importing and going through customs in
Haiti is definately a pain and can be time-consuming.  You may pay more $
locally but will pay less in problems, delays and frustration.  (SELF has
been working there since before the quake)

A doctor in town has started an orphanage in Haiti and while it has
connection with government power for a few hours per day, it of course is
not reliable and is very expensive. We are still in the stage where we are
trying to figure how to shed as much load as possible. I have no
territoriality in this project and will help provide system design and
hardware at my cost, however apparently tariffs can be huge so we may want
to source as much as possible in country.  Can anyone tell me which solar
NGO's (SELF?) you'd recommend to tell us what hardware (deep cycle
batteries) is available in country? And if it is a simple UPS system,
storing from the grid, what grid-connected battery chargers does everyone
recommend for a fairly large battery bank? Used to be Todd chargers and I
wondered if they've corrected problems or passed on to some other company.

 

Thanks for your suggestions.
