I recently received my very first wind turbine from, wait for it.. you've guessed it!
https://www.aliexpress.com/item/4000707176751.html
I ordered the 48 volts version.
Images below
Now I do not expect the advertised 6000watts of power generation potential and even the seller admitted only to expect 4000watts which I still do not believe.
I did not order any extra components yet as I first want to test what it can generate as my location is ideal for high wind loads even though in an urban area.
Now how can I test what the 3 phase AC generator is generating in terms of watt, amp, volts and the likes (please forgive me if I include units here that are not relevant in this stage as I am a total newb)
There are 3 wires available (I am assuming one for each of the 3 phases) where I can connect something while it is spinning to see what, if any, flows over the wire.
Could anyone please advice me on how to proceed? what tool to buy to be able to test the power generation on each of the phases.

TL;DR Update
Current verdict = Don't do it!!!
The blades need to spin far too fast for the alternator to generate any useful output. That is not safe.
I am considering a vertical turbine at the moment knowing full well the efficiency will be even less that a horizontal one like this but I believe they are less dangerous.
alternator output with 3 phase full bridge rectifier attached;
with load (details below)
rpm: +- 820 (my poor drill has difficulties)
Vdc: 2.45
Adc: 1.65
The load details (light bulb)
resistance = 2.5
12V
55W
Results at +- 320 rpm and 4 x 12v5w bulb in series (48v 20w load if not mistaken)

Building the sickest ® VAWT ever. Brilliant minds unite please!!
--- TL;DR update UPDATE: 25/03/2024 please allow me to be a little Nordic. Can one please distill all new information into a well defined graph supporting ones intentions when one comes here as a new comer adding new information to the cause. In case that is a little challenging then a well...
