Watt is the answer?
How many watts of solar electricity is required to run a Casita? Has anyone tried wind power.
How does one run a refrigerator/freezer on solar power.
How many storage batteries are required?

I believe the answer to this is different for everyone - and it depends upon you, and what your intended needs are (plus what your discovered needs
are once you get going!).

I figured.
But is it possible to determine a sort off. "Baja offgrid standard".
Kind of a beginner minimum?
A tv, a fridge, lights,
When preparing for an offgrid life these are the sort of questions that arise.
Most solar systems are expandable too.
So to figure out the minimum buy in you first have to determine your minimum requirement.
For example. I figure a 3000 watt generator will run a 26 foot trailer.
But my 1st project would be to set up a solar system to replace the generator.

The good news is that solar systems are fairly modular so you can add capacity as your needs change. We started off with 3,500 watts solar capacity on
the roof and 12 huge 4 volt Rolls batteries in the garage to run a normal 2 bedroom house with all the usual appliances you would have stateside.
After adding a swimming pool we increased to 6,000 watts of solar panels with the same batteries. You can easily spend $20,000 on batteries alone.

Check out Dyno Batteries in Seattle. They have been building industrial batteries for the railroad and other applications since 1933, and they are
reasonably priced.

I have no idea what you will need but my place runs on 2280 watts of solar on solar trackers which makes them equivalent out put wise to 3000 watts of
solar panels. I run 2 elec refers, a chest freezer, all my garage tools, table saw, skill saw, small mig welder etc. lights, TV and dvr, microwave and
all kitchen appliances, clothes washer, and gas dryer. When the sun doesn't shine for a few days then I run the gen to charge batteries. All in all it
works just fine. You need to figure out what you are going to be powering and size your system to that estimate. Probably you would want to double
your estimate, there are always things you didn't plan on, like the wife's elec coffee maker, hair dryer, curling iron, washing machine, clothes
dryer, and on and on and on.
good luck with it.

Thanks! About what I thought.
I'm going from "fear of the unknown" to "Internet expert".

I like this little system.
Good little starter kit or waste of money?

Depends on how much you're prepared to adapt your lifestyle. My first place in Baja was a secondhand 5th wheel. Fridge, cooking and hot water were
propane, no TV, no 110V things at all, so my main power draws were 12V lights and the water pump. One 7A solar panel, a couple of batteries, and a
controller (no generator), installed cost well under $1000 12 years ago.
But that's probably more basic than most would be happy with, especially for a full-time place. And things have changed, fridges (and even
minisplits) have become much more efficient, lighting can now be leds.
One item that is surprisingly heavy on power (especially the start-up surge) is a microwave.

don't buy that $1000 set...waste of money
i'd stick with larryc advice
buy outback inverter and charge controller
don't buy a windmill...they are NOISY!!!
not a good investment

Again, also what I was thinking.
I know I will need some good components eventually. Enspecially when I put in my pool and jacuzzi... later. And a sauna. I'm a sauna junky.
I am only planning on living in my trailer 2 years max while build.
I will eventually put the panels on the garage roof and the garage will be the first structure. Then the 1st casita.
So the system is really for the casita and later when it grows into a full casa and maybe even a casa grande.

When designing your garage try to have the roof facing the right way for solar and roofing to allow you to install the solar racks easily. I think a
good starter system would be 4- 220wat panels with an area to expand for 4 more when the casita is complete and you're ready to make it a house with a
the goodies that use power. A 4000watt inverter ( I have a Trace 4024 - almost 20 years old now) and an Outback 80 amp charge controller. You'll want
a combiner box for panel connections and a breaker box / switch for the panels and another for the batteries. Batteries... There are a lot of ideas on
that and newer technology coming out now and in the near future to make the choice difficult. I am still using L-16 batteries and have 8 of them. No
hair dryer, coffee maker or cloths dryer. You can always top off the batteries with your generator that will run a mini split AC if needed. Craigs
List sometimes have some good deals so watch for them. Check with neighbors to see what works for them and what their usage is. Oh, I'm starting to
switch out lighting for the LED type now. They use about 1/2 what I had or less. Put in some serious thought for house wiring and an expandable main
breaker box.
Good luck!

That inverter in the picture does not appear to be an inverter/charger. Typically solar batteries are very high amphour capacity and to recharge them
can take a long time unless your charger can put out high amperage. My outback inverters can put out 125 amps to charge the batteries. So suppose your
batteries are down 400 amphours to recarge them with the inverter acting as a charger would only take 3 to 4 hours (because of the tapering charge)
but to charge the same battery using a small automotive charger could take days of generator time. I find the inverter/charger to be a huge asset in
my system.
And I agree with Bob, rotating machinery breaks, usually when you need it the most. Put your money into solar panels. I would start out with no less
that 1000 watts of solar panels and plan on doubling that. Another consideration is the voltage of your system. If you go with a 24v or 48v system you
will save on charge controllers and wire. You can use smaller wire with a 24/48v system.
Lots to learn.

My wind generator makes very little noise. Works great in our windy climate. I know others in the San Quintin area that say the same thing.
