Connecting small wind generator to existing solar system

Hi all,

I've got a very small scale solar system on my house which I use to run
a couple of lights and a small 12V marine pump. Circuit details here:


My question is, how would I go about wiring a small wind generator into
the circuit so that I can charge the battery from either solar or wind
- whatever is available ?. I assume I'd need another charge regulator
to work with the wind generator ? Would there be a problem of
interaction if both the solar panel and the wind generator were
charging at the same time ?

Has anyone out there got a setup that includes both solar and wind
generators ?

Most small wind generators have a built-in charge controller. Just
wire the wind generator output parallel to the PV controller output.
Fuse and cut-off switch (if any) per manufacturer's instructions.

You'll likely set the wind generator's controller slightly higher than
the PV controller. Some tweaking may be required if you find the
controllers switching on and off more than you'd like.

I've had both for many years. They compliment each other nicely.

 Is there some rationale to setting the windmill higher than the PV or
is this a personal preference to your situation and environment?
Previos posters expressed the PV slightly higher than the wind gen.

Many of the cheaper, and maybe some better??, wind controllers have no
adjustments on them.

Turbine dump controllers wired in parallel with PV would be dumping
the PV output, or more importantly, dumping more current than the
turbines dump load is designed to handle.

I don't remember seeing that, let's see some quotes.

That sounds like typical Gymmy Bob butt-smoke. Here are some examples
of the most popular turbines on the market, all of which include
adjustable regulation - http://www.windenergy.com/air_x.htm .

turbine controllers which aren't adjustable.

A good PV reg will allow for control of a wind gen.

BTW Do a search on google and see if you can find wayne's site. It seems
to have disappeared. Again.
