Hello everyone

Im new to this forum from South Africa, doing a small hydroponic project for developing rural settlements who struggle during the crop season! and would like to know if the following items I want to get will work well together. Its basically a solar powered hydroponic tower. I tried to give as much information as possible and drew a picture on how i would put it all together lol ¯\_(ツ)_/¯ idk (Attached!)

Open Circuit Voltage – 21 to 22 V
Short Circuit Current – 1.3 A

L.E.D's x3

( ͡° ͜ʖ ͡°)................................................................................lol
if my drawing offends you im sorry



Thanx!!

 

So, you already bought all the stuffs or you want to build them?

>Control power timer switch (it would be every 20min 24/7)
What's the meaning of 24/7?

>Programmable : 17times(week or day)
More details.

>Normal Power Current Impp (A) – 1.1 A
What's the meaning of Impp? (Amp, Input or what)

According to the block diagram, the device on the right side, they all connected in series, I think their could be have a problem, could you explain all the details according to block diagram, such as when the timer time up what will be happen, and according to what condition to set the timer, what time the water pump, pc fan, led will be active, you didn't describe the spec of leds.

 

I have the battery and i want to buy the rest. Im not to sure what Impp means either .

The water pump, pc fan and the 3 Leds should switch on all together for 20 minutes and then off again for 20 minutes and so on......(for about 30 days)
Link to the timer
https://www.amazon.com/FAVOLCANO-Di...2467026&sr=8-1-spons&keywords=12v+timer&psc=1

something like this

 

24/7 means 24 hrs, 7days a week

 

Hmmm !
A 12V 7AH battery requires 0.7A Current limited charger so that battery life can be maximized, so I would chose a solar charger of around 1 to 2 Amps to cut down cost. A 10 amp Charger is overkill.
plus the charger needs to be a SLA charger type since they require a constant current to charge at max of ~13.85VDC.
Other than that you are good I believe.
Plus everything needs to be connected in parallel.
The LED details are needed as like, RED, GREEN etc. Since different colors take different voltages. You can connect 3 of them in series ( 12V supply ) but still you will need a series resistor which can be identified once you chose the LED color and type (assuming 5mm standard LED)

PS.. the pump will be connected to Timer (so not all in parallel)
and if you like to charge the battery at low sun light, you might need to find a panel than can supply ~20V at 1A in that level of sunlight. But the panel you describe will work in Good Sunlight

 

24/7 means 24 hrs, 7days a week

I thought something like that, but I can't figure out the real meaning, so the timer can be setup to one week long and repeatedly?

 

Average drain about 1 A @ 50 % duty. One day = 24 Ah. Needed battery maybe 2X = 48 Ah.
Solar panel needed, 48 Ah / 8 h. of sun = 6 A, or about 72 W.
Timer, 555 IC & relay.
Review of figures is suggested.

Thanx!!

I want to ask, were you able to complete this project. I am working on something similar and would appreciate your hep. thanks.
