Lorentz pool pump HELP!

[Villaella]

I will be installing a Lorentz P600cs-15-1 ( formally: PS600 Badu Top 12 ) to filter my swimming pool in Spain. Today I have bought: panels of
2 x 220w 29.5v.
1 x 230w 29.5v

And one that I could not refuse at the price: 1 x 190w 36.6v.

Here is some info on the pump controller:
Max power Input ( Vmp ) min 68.
Open Circuit ( Voc ) max 150.
Nominal Voltage ( Vdc ) 48-72.

Here's the questions:
How do I wire the things?
Can it be possible to include the 36.6v panel in the set up along with the 29.9v panels, or do I stick a for sale sale sign on it?
Would it be possible to run this pump with just three panels?

Any help would be a big help.
Oh I am OK with pipes.

You really should not have went out and bought panels before you know what you need to start with. The 0dd=ball panel is useless. Reading the spec you need anywhere from 500 to 1000 watt solar panel depending on lift and solar insolation.

In addition you are going to need a charge controller and batteries.

Hi, I installed a PS 600 Lorentz swimming pool pump. I have the pump running with a 500w/48v solar system (2 panels of 250w/24v). Anyhow, the vacumm inlet doesn't seem to be very strong and I wonder if I should add another panel of 250w/24v?. My question: would it be ok have a 750w/72v running the pump?
thanks for the advice

[Villaella]

Cheers

Thanks for that.
So I have enough panels then, and a double my money on ebay with the spare 190w.

[Sunking]

So I have enough panels then,

I never said that or implied that. In fact I suspect you do not have enough panel wattage nor compatible with your intended battery and charge controller.

[Villaella]

No bateries.

Hi
The system does not include batteries, I only want it to pump durring daylight hours.the panels can be wired direct to the controll panel or with batteries if wanted.
There are a couple of snips on Youtube where the same pump is powered by 3 x 180w panels, I have 670w.

What I need to know is how to wire them, series or parrallel or some otherway?
Thanks

Do it just like the one you saw on youtube.

There is a good chance that youtube is the worst source of information there is - it is directly after wikipedia as far as reliability.

[Villaella]

Thanks

Is there any one who can answer my question.
Please.

[Sunking]

If you would read the specs you would know the answers to your questions. Minimum pump voltage is 48 volts DC nominal. If you wire the 3 panels in series should work for at least an hour or two each day.

Question is that going to be enough to keep your pool clean. That depends on the size of your pool, how much water the pump can move, and your location. The pump is not very large and about the right size to keep a soaking tub clean.

What is the pool volume?

[Villaella]

40,000 Ltrs

[russ]

total lift flow rate power input current input
[m] [m3/h] [W] [A]
2 12.8 507 10.6
3 12.3 502 10.5
4 11.4 496 10.3
total lift is (static + dynamic) head

The numbers are per operating hour

If there is a filter in the system the available pressure/flow will be reduced.

So say 12 m3 per operating hour with full sun - you need to turn the pool over (40 m3/day) at least once a day for sanitation - many places call for 3 plus turnovers.

The pump requires 500 watts to operate at spec - panels are rated at STC which is 1000 watts/m2 and 25

Thanks Russ

Thanks Russ
So will it make a difference in that there is only a maximum 2M lift required?
From your calculations what panels will I need to add to the 670watts I have to cover the shortfall?

Thanks.

I am going to ask Mike or Sunking to chip in again - to try not to get you into trouble.

Here is my estimate - based on PV Watts insolation figures and rules of thumb.

1) You can depend on a 100 watt panel to produce roughly 80 watts of power (derating from STC conditions that are not realistic). A 100 watt panel will only put out 100 watts on a perfectly clear midsummer day when it is cool and the sun is perpendicular to the panel.
2) For every

Dear Spain i have the same system it doesnt require batteries to run the pump just wire the 29.5 panels in series and the pump should run just fine

[Villaella]

Thanks to all.

Dear Spain i have the same system it doesnt require batteries to run the pump just wire the 29.5 panels in series and the pump should run just fine

I have now completed the installation of the solar pump system and it works perfectly.

I used 3 x230 watt panels wired in series, no batteries.

I have left the ac pump in the system so I can still clean the pool after the sun has gone down.
