0.5kw hydro electric project

That is an actual Pelton wheel (in plastic). It has one nozzle, could be fitted with more.
When you redo you system larger, consider bronze.

Check out the chart giving head loss per 100' of pipe, vs. water flow and pipe diameter.

You would be able to determine its optimum operating point with your pipe.

With the listed turbine's 5mm orifice & 28PSI, the flow thru the turbine will be about 5gpm or a bucket full at best.

I repeated the bucket test today multiple times with stop watch and you were correct its around 6.8 seconds +/- 2 tenths to fill a 5 gal bucket. So around 41-43gal/min flow rate. I also today hooked all my 24v lights laying around totaling 65w and the batteries were still gaining charge so turbine is putting more out then that i presume.

I swear, that looks like the impeller for a vacuum cleaner.
Suspect it is much lower efficiency than one actually designed for hydro.

The toothed pully is also a sign of something repurposed.

First order of business is determining flow x pressure representing max power delivered, as Russ is guiding you through.

From pressure you can determine velocity of nozzle output. For a Pelton wheel, maximum power transfer when buckets move at 1/2 that velocity.
Select a turbine to support operating conditions. There should be some way to tune load to hit that RPM; one might be adjustable constant-voltage charge controller. Don't know if any MPPT do a good job for turbines.

Obviously much larger pipe would have worked better for the flow you want to use.
Depending on terrain, could divert and run in a ditch across hill, make shorter steeper run in pipe.

Actually the fan from a lawn mower engine.

Hopefully he discovered his need for a proper PWM controller like a TS-45 or TS-60 from Morningstar and a proper Turbine like Harris or some from Hydro Induction Power. One that you can get in 12v/24v or ideally 48V.

The following figures are for a pelton turbine by Powerspout.com. With 1100ft of 2" pipe (you don't say if that's internal diameter or not), 65ft head and 41gpm flow rate available this calculates out at 55W output for a 1.6" internal pipe diameter (2" external) or 111W output for a 2" internal diameter pipe. Your pipe is just too restrictive to allow your available flow if it's a 2" external pipe (assuming smooth bore plastic) and at best would be reduced to around 30 gpm. Here's links to help you with the calcs:
