Sunsynk Ridgeblade

Don’t you just mean a controller as most of the turbines have?

I know the Sunsynk’s are turbine aware, so maybe that’s all it means.

The literature I found specifically called it a wind inverter.. what exactly they are referring to, I don't know.. they didn't go into specifics about the so-called wind inverter..

Most wind turbines output 3-phase AC. For it to be used on a Sunsynk MPPT controller, it needs to be DC and within the MPPT's specific electrical parameters. Or a single phase needs to feed the Aux of 3 single-phase Sunsynks, within the Aux's electrical parameters.
 
The other thing about wind, as far as I am aware, you can’t just ignore the output if you don’t need it as you would with PV. If the wind is blowing then the electricity needs to go somewhere. I think the controllers for the Tesup (spelling?) wind turbines dump excess electricity through a resistor and just heat it up if not in use.
 
Call me back when these are production ready. They have been around for years but never really got anywhere.

No thanks. Electricity at the price of diesel? I'm not that desperate.

Short memory? Where do you live?

Cheaper to run it for 2 hours to charge the batteries than having 7 days worth of battery storage.

Durban, PV still generates power when its cloudy.

Huh? How can it be cheaper. Please elaborate.

Of course PV still generates power when cloudy, just not enough to run a dishwasher / tumble drier / water pump for any length of time.

70kWh of battery = R462 000 vs 1 x 10kW genny = R30k

Get more PV, use the grid/battery/generator of the few times a year you have this situation. You wont run those things off wind either.
 
The whole idea behind the wind aspect is that it's uncorrelated with the sun. "moar pv" only helps up to a point - the electricity only comes when the sun is up, while wind can happen at any time. Since you already have battery storage, presumably you are in a position to stash the wind power whenever it comes up.

Generators are loud and messy and require maintenance and refuelling. I'd much rather stick a wind thing on my roof (assuming the costs and output are reasonable).

But then my goal isn't 100% off-grid, it's "I'd like to live my life and not worry too much about availability of Eskom". If grid is there on a cloudy day, I'll use it.

PV doesn't work at night whereas the wind does blow at night..

The point here is NOT use wind in place of PV but, use wind to supplement your PV.. This, of course, assuming that this is cost effective depending on the price this ends up being..

You are fighting every one in this thread, seemingly on the premise that everyone here wants to use this in place of PV, when they don't.. purely supplemental..

And all I’m saying is the money spend on some wind blowing sometimes is not worth the money imho.

If you want to get turbines, go ahead.

Do you know how much the system is going to cost..? Until there is a solid idea on pricing, you can't say it's not worth it..

How can you compare kWh with kW? How about adding runtime and maintenance to the equasion?

PV does nothing at night and is sub-par on heavily overcast days. That's the point of an alternative. I already have 400ah of battery.

Sorry, 10kW genny R30k plus R20 of fuel for 20kWh.
