I was only reacting to the photo he posted

DanDeeBoss:
I'm not understanding, unless it's sarcasm

How did the bullets get to them??

SolnergyPower:
Meet those guys selling aluminium products, show them the attached pictures.

Depending on where you live, it is usually between N1800 and N2000

Thanks
I am just a bit skeptic as how efficient the 24v will be as against 48v which supplies more power and possible produce a better pure sine wave
please correct me if am wrong is my assertion

Below is a schematic I pulled from the internet. The contactor is wired as shown. The two switches, red and green are the two switches that control the contactor. When they are both on, the contactor closes and supply power to the pump. To use it for float switch or as a switch, you keep one of the two switches closed by connecting the terminals together without a switch in-between. Then you connect the float switch (or any other switch) to the second switch. When your tank is full, it pushes up your float switch and makes it horizontal. This will disconnect the contact in the float switch and switch off the contactor. When the float switch drops and becomes vertical, the contacts will be made and switch on your pump. I actually leave the other switch connected so that I can turn off the contactor/pump whenever I wish. If you don't connect the second switch, you will have no control over the pump, only the float switch will do the control.

adrusa:
Yes. The contactor will do the switching of the pump. The float switch will just switch the contactor. That way the high current needed to drive the pump will go through the contactor while only the very small current needed to switch the contactor will pass through the float switch. That way you will protect the float switch and not need to change it too often. I haven't had to change my float switch for about 5 years now. If the float switch powers the pump directly, it will get burnt and need to be replaced very frequently.

This birthday, I'm once again reminded of the bountiful joy that I've reaped from my family and friends, and how blessed I'm to have so much love from everyone around me, thank y’all from the bottom of my heart.. it’s all love ❤️ from this side!!

Shalom!

Thanks, based on the price this one na kiv o...make I rest from lifpo4 expenses first

5.4KWH 24V lithium landed, will put to use within the week for testing before sharing my experience compared to my current 300Ah 24v Lead acid.

Is it’s stated on the school website that it is a Christian university?

Go on the website now and read their mission and core values. There is not a place where they made mention that it is a Christian school.

My pure sine wave inverter finally arrived in just 10days using China post and working perfectly after installing. No more humming noise and fear of my gadgets developing fault due to voltage fluctuations. Batteries now last longer compared to when I was using my former modified sine wave. It's definitely a 5star inverter & I'm very happy

mcTrinity:
hi Ola,

you're looking at something like this... the two separate battery banks can be independently charged with inverter or solar...

please, ensure you use a quality Change over switch. I used 100A A&Bt brand ... or you look for MG brand. confirm the thickness of the current-carrying part...

Hope this helps

cheers

ceaser:
I will love to have this type of yours. How can I go about it? Online stores? Walk in malls?

Thanks.

And that polystar 1.5hp AC seems to have a friendly power draw of less than 1kw at full blast. Is it inverter AC?

WHATS STRANGE ABOUT the reading?? IS IT AN INVERTER AC

We use nails. We also have flash bar (you can get this from those guy selling building materials) to seal where there is an opening that will lead to leakage.

After we finished installing the panels, we access the ceiling ie in-between the roof and ceiling, this area is always dark. So if you look at the roof from inside the ceiling, you will see holes or openings if there are any, then you can seal the roof with your flash bar from inside the ceiling too.

ojeysky:
Sure I used the attached recommendation that I got from a friend after we brainstormed about it. Though I didn't get to plan for 12 anymore. I only did for 9 panels. Ingredients:

3" Galvanized poles
1.5" angle bars
12mm rods combined with 8mm that I had at home.

Welder put it all together and then the rest is getting it strongly fitted with concrete. It's standing now. Hopefully next weekend will get to move the panels.

As long as the asbestos roofing sheets are still strong, you should not have any issues. You may use a roofing guy as a precautionary measure if you are not sure of the status of the asbestos.

There are standard solar panels mounting kits sold here, those should help. But if you are low on budget, you can use those aluminium frames used for making windows frames as shown below.

You are indeed a cruel, evil and sadistic sub-human being, to be making jest and taking delight in this terrible violation of an innocent child.

I hereby invoke the almighty power of Ogun, the God of Iron, who will very soon direct you into the hands of armed robbers assigned with the sacred duty of beating you with iron pipes, to within an inch of your life.

Bimpeusman:
Visit hospital.. for check up...

If they beat you, or ur child like this.. what will you do.

Did you know. how much the girl parent have spend still today.. that you are talking trash

Looks good!

Although at first I struggled with the cable gauges used especially 2.5MM wire from panel to CC. If possible you should at least match the wire gauge of the panel cables in the panel to CC connection.

If I understood correctly, you have just 600 watts of panels deployed right now? You must review the suitability of your cable gauges if you ever plan to upgrade.

How is the Knife Switch handling arcing with DC currents passing through when you (dis)connect the PV array?

I have played several times with the idea of using a 200A knife switch as a manual disconnect from battery for my 60A MorningStar CCs (2 units with 1 unit to each pole of the knife switch) but fear nor gree me do am - the copper in the knife switch definitely looks like it should take it but you just never know especially with CCs & PV array fond of doing ~3kw each on a regular basis.

durodee:
Materials:
1) 1 roll of 2.5mm copper wire -red (panels to knife switch)
2) scrap length of 4mm black and red copper cables (knife switch to CC)
3) 10mm multi-strand copper cables (CC to 200 amp 24v battery bank)
4) 100A knife switch
5) 30 amp MPPT EPSolar CC - bought second hand from Bigrover years ago!
6) Aluminum pipe ( left over from window construction) to serve as base for the solar panels
7) 6 nos 100w panels =600 watts

Results:
Instantaneous yields of between 18.5 amps to 19.9 amp around noon . approx 19A×24v= 456W using scrap materials.
Opinion:
Start with whatever you have; upgrade as quickly and as soon as possibly; you don't have to break the bank to enjoy Solar.

Update on my thin film panel experience:
About 3 years or so ago, I got some set of thin film panels- each 100W @ 99+ volts. I installed 14 then and just kept 6 in store. I recently dabbled to a venture that increased my water need and hence power need. I therefore ransacked my store for leftover electrical materials from my building project and here are the results.
