g'day everyone,

Is it possible to have both the windpower generater and solar panels running
directly through the same regulator and same batteries?

or should they be separated? ie 2 regulators, 2 lots of batteries, 2 inverters etc?

thanks bob

Hi Bob

Its good practice to separate the regulation of panel and wind turbine unless you have purchased a controller designed to handle both as some of the more sophisticated wind turbines have.
A wind turbine has specific needs such as a dump load for high winds and high output voltage therefrom that isn't ideal for solar panels.

A common battery bank and inverter system is no problem.

If you could give us some specifics of your proposed system I;m sure that our guys can help you some-more.

All the best

Bob

Yep PLasmatronics do a range suitable for both with one battery bank, and i might add it works very well, just lacks MPPT for the panels.

PL20 also Dingo (same thing better looking case i think)
PL40
PL60

My money is on the PL20 as with an external SSR relay can PWM control a massive dump load and good for 12/24/48V
thus probably upto a 5KW windmill. all for under $300.

I run one, Gordon runs one, Phill runs one so as far as forum members in the know, she's a winner.

The inverter will then be on the other side of the batteries Grid tied or standalone all AOK.

Why do you need a doctor?

You might need to tell us what is your problem first.

Pete.

Sometimes it just works

G'day everyone, thanks for the replies,

my system at present is just a 80watts panel with 600watt pure sine wave inverter
and at present one 110 amp hour battery, this is 12volt system.

as im also looking to buy a small windmill 300watt system to suppliment what
i have at present but i will upgrade my solar panels to 200 watts later.
maybe one of the jaycar windmills as they seem to be cheap.

Over this weekend i visited a farmer i eastern victoria and he had a 300 watt
windmill on one his shacks, hooked up to a huge battery bank running a bar fridge
and a few lights, but he wants to add solar panels to suppliment his present
system, and his system is 24volts.

he told me he can run the fridge for 4 days straight off the batteries before
it shuts down, and he was temporary using 5000 watt modified sine wave inverter.
athough he coulnt get a 2000watt electric grill to work while i was there,
maybe the batteries was down a bit.

However, while i was there i shot some video of his system and of the windmill,
and i noticed that the windmill doesnt always spin constantly,

we were discussing over a cuppa, running the solar and windmill through the same
inverter and regulator, which i thought was good idea to find out, before he
puts up his solar panels.

cheers

Hi Bob

From your description it would need a solar regulator for the panels as the windmill one wouldn't be suitable to run both systems, as one is probably a 3 phase AC for the windmill and the solar would be single DC for the panels.

All the best

Hi Bobt,

that 5kW inverter will be hungry for power all of the time. I had a Selectronic 5kW unit for a while to test, and it consumed 60W,just turned on. This was over 1kWh per day.

Hi All

My 5kw inverter draws .7 amp 25 volt on idle so I put it on a timer so its switched of from 12 pm to 7 am when nothing is being used, it saves running down the batteries for nothing when there isnt any solar input.

The option is to put on another panel to make up the difference, may do that in the future.

All the best

Bob

g'day everyone,

thanks again for you replies about windmill and solar regulator,
i will pass on that info on the farmer bloke next time i see him,

appreciate your comments,

Im thinking also of getting a small windmill or even an 10 amp vawt
for my own system, as im going 6 month camping trip next year, and
my solar panels will be coming with me,

so a small portable vawt hooked up to my battery bank will help top
up the batteries during the evenings or when its wind and rainy and
im stuck in the bush, can keep the waeco going and watch tv/dvds.
without worrying about the batteries running down.

cheers
bob
