Ejiyke24:
An urgent advice is needed please,Can i buy a solar panel and charging comtroller plus deep circle battery and use my ups as an inverter itself?

Yes..

earthrealm:
your plan is doomed from the start, make effort to read previous pages, this issue has been discussed a thousand times.

max load u shud put on a 12v 200ah battery is c/20 wch is 10amps which is equal to 120w, since u hv 2 of them, then its 240w...u may not do serious harm to the bank if u intermittently draw x2 of this say 480w for short periods ie c/10, but anything higher than this...spells premature death for the battery.

google well, to gain more knowledge about what you are about to enter into

Thank you.
I have been reading through since Sunday afternoon I saw a link to this thread.
But, you know how it can be. I seem confused along the line, regarding which choice to make and pursue.

Please help me with this...
1. Outline what I will need to run a continuous load of say 500watts for 18hours.
2. Outline what I will need to power same 500watts with water pumps.

This will guide my budget please.

Guys, Guys.........,
do re-check ur energy requirements. How can u/want to run 500 w for 18 hr, haba! don't you go to work?

Note; answer to 1 above
@50 % dod u will need nothing less than 1100 Ah 24V batteries, panels not less than 5500 w, CC of about 140A @24V. So do u still want to continue?

You don't know what I need it for.
Don't I go to work? No need for such line bro.

Stating 18hours, do you know if I want the powerbank to be capable of that?

And yes, I need it to capable of running continuously for at least 12hours when not being charged.

Donsco:

Yes, I would like to continue and I believe these responses will tailor my options and decision aright.

Good morning,

please, can the DC flex cable (used in Solar wiring) be used for Thunder arrestor and grounding installation ..?

I know, normally copper tape or stranded copper is used for thunder arrestor and stranded copper is used for house earthing... just wondering if the DC flex cable can also be appropriate.

thanks

Let move forward; things to note
1. @50% DoD for the batteries, a very good brand @12v will give u around 2yr of use (I would not recommend 50% DoD and would not recommend 12v, go for 2v to achieve ur desire voltage).
2. 24v system is not recommended here, y? cos u have to know what u re doing in terms of wire gauge, for this amount of current, u need to go max on the wire size! So i would recommend a 48v systems (500 w continuous is a lot of load)
3. Inverter? u may need to go or at least near premium brands here.
4. For pumping machine, I don't know if I have missed the rating, how many hp are we looking at, how often do u want to pump in a day, do u wish to pump during Sun down hrs too, if yes, how long?

Let start with this first.

Topmost11:
It is the combined panels, not a single panel o. If a single panel has that, then life is really good

Lol

earthrealm:
that has an inherent problem, and would need expert supervision to make sure damage doesnt occur.

am thinking along the lines of overcharging the batts..., assuming his pumping machine is 1.5hp..ie 1200w approx, he would need panels of that wattage to scale by, factoring in losses and all. say he has a 1500w array, at 24v, thats about 55amps or so...though average wud be 30a to 45amps, i averaged same when i had 1500w on a 24v inverter. let him steer clear of flooded batts, as they dont like such high currents, as i dont think it would be possible for him to always be available, monitoring the harvest, so as to go switch on his heavy loads, when harvest is high...

Yes it needs supervision or/and automation, I believe some of our veterans here have once used or currently have similar system in use, though he may need to double the battery he quoted.

I also align with your opinion but I believe there's a way around it. a timer would definitely come in useful and also opportunistic loads like a fridge or freezer to mop up excess current which would prevent overcharging of the batteries during the day and periods when the pumping machine isn't in use and also a good battery disconnecting module to disconnect the heavy loads during periods when the weather is bad or for a particular SOC of the battery.
These are assuming he only runs such heavy loads during the day.

I think you will be fine with 600ah 48v battery bank, or at least 400ah 48v if you can do an energy audit of your appliances. A rugged 3.5kva Indian inverter should be fine with 80a 48v mppt cc, then 6kw of solar panels. Just make sure you hire a professional to install as this is not a project for amateurs.

Thank you.

I based my calculations on the fact that I power same stuffs with Sumec gasoline generator SPG 2500.
5.5HP
Rated AC current 9.1A
Rated output power 2.0kw

Pump twice a day. Morning and night.

I have decided to use a 48v system.
I will start with 12v 200ah batteries and upgrade to 48v lithium battery later.

Have read through.
Considering cost and efficiency.

Options in view:
1. Prag 7.5kva 48v (can set DoD between 50% to 100%)
Prag 80a MPPT cc
8 units of 12v 200ah

2. Fangpusun xtender 4000va 48v
Fangpusun flex max 80a mppt
8 units of 12v 200ah

Still checking out.

Yes, but.... Any conductor can be used, but it will not be as effective as copper. The idea of a lightning arrestor is to provide the path of least resistance to the earth, that is why pure copper is used since it is the best available and affordable conductor.

But I will definitely make use of solar pump in my other project next year.

You can use that. Just make sure you use the right size.

NextDayPP:
If you decide to use the higher rated MCB for the same cable, you need to understand that it is a risk and maybe it will make you more vigilant (constantly looking out for any signs of a fire).

To prevent a fire, you should use an MCB with a lower amp rating than the cable not higher



Messrs Waziri and Richmond, I think you missed the context of my post entirely. I was just trying to make a joke out of it, if anything, I was eager to see more inputs/corrections on Mr Makevele's installation. I quoted myself and copied your post above incase you dont want to go back and read over again. I used the word 'Oga' and said thank you at the end. I can't see where I said anything against you, or maybe my use of English is bad. I AM SORRY.

Let me use this opportunity to tell everyone how much this forum has helped me and why I think it is the BEST in entire nairaland.

I started in 2010 by buying 200AH battery and a 1kva inverter at Bluegate in Ikeja for my shop following someone recommendation. I plugged my 1.2kva UPS into the outlet of the inverter thinking I needed to regulate the inverter power as I did gen and PHCN, plus I had in excess of 400w constant load. The battery died in a couple of months. I was told at Bluegate my load was too much and that I shouldn't have used the UPS. I didn't care much about the money lost because I was to exited that it actually worked. Bought another battery and took the system home because I could not reduce the load in the shop. That lasted about 2 years because I didn't know I could add panels to it and PHCN was better then.

Today, still on 200AH battery, with the help of this forum, the max I put on the battery is 100w
This forum has taught me to check device power rating before buying
You pro taught me the importance of accessories like breakers, fuses and meters, (even on basic and small systems) so much so now that I have a meter for USB devices like phones.
This forum made me know there are DC pumps, and have since ported to DC pumps for my farm use. I could go on and on.

Since I came across this thread about 4 years ago, I have done close to 20 small and basic installations for myself and friends, and when some of my friends are ready to go big with 48v systems as they have indicated, I already note down who to call from here to help. Those that will attend to you even when you are buying just a single panel and will not ignore your messages because you are on low budget.

I come here to learn not to contribute and will also learn as long as I live, unless telling Mr Dmerciful where to get low AH batteries is a contribution

In agric section on nairaland, everyone wants to get paid for every little info, even though some of them are internet farmers and not practicing, reason this place is my best. You ogas here don't know how much you are valued, you don't. there are hundreds even thousands learning from you secretly.

It makes me really sad to see your comments yesterday which was my birthday. Again I am sorry.

I wish everyone a fulfilled week.

Makevele is a clown and fake programmer tho.
Now takes him serious

I got about 18amps from my 260watts solar panel yesterday, it was delivering about 8.5amps at 36v before which is highly inefficient for a 12v system, was thinking of buying an mppt controller but was short on cash, researched and came up with a way of splitting the solar cells into two groups of 18v each thereby increasing the current. Now my battery enters float before 1pm

throw more light on this your research...you had a single 24v 260w panel? and u somehow managed to split it into 2..and solder cables to them?, effectively convert them into dual 130w panels, or you wrongly hooked it up to your 12v pwm CC asa single 24v 260w panel

or you have 2 units of 12v 130w panel, which you wrongly connected in series for a pwm CC, but u hv now realized your error, and hooked them up in parallel?

It is a single 260w 36v panel, with a total of 60 cells, I divided it into two making it 130w 18v outputting around 18amps from the previous 9amps

does anybody have any experience with voltron 24/48v mppt charge controller?
which major brand is it a clone of?
i am in need of the manual....who can help?
