s
Inverter (standalone)
Charge controller (I'm not a fan hybrid system)
AC n DC cables
Earth rod
MCB SPD n DB
rack

Could you give an estimate and breakdown of what this would cost, more specifically the inverter, cc and s?

Abeg help put mouth

Abeg Veterans abi experts in the house. If you are carrying 80amps from your charge controller output to your battery. What size of wire do you use. You guys with 80A, 120A controller for a 12v system. My controller and battery are quite close to each other. This my online calculator is telling me 26mm. How will 26mm wire enter this tiny hole in this charge controllers. Not sure I am doing my calculation right

Probably your batteries are full, if not try put on the inverter to draw some watts and if the cc will draw some current from the .
Also, snap the battery voltage and current interface of the CC.

I am lost o. Is this meant for my post?

icjunior:
I just installed 2*475w jinko s and powmr 60a cc.

My tubular batteries are very low as they're showing 20v on the cc,but the issue I have now is I'm seeing the charging voltage from the cc,but not the wattage,I don't know if that makes any sense.

The inverter also isn't on atm because I intend to charge to 27v atleast before powering it on.

Could the inverter not being on be the reason why I can't see the wattage from the s?

Did you configure it for tubular battery?

Remove solar input and put it back

Then go to settings D4 select 00.

This is default settings for lead acid.

Then proceed to set the voltage of the battery D1 and D2 I think

What type of charge controller are you using? Can we see pictures for PV wire and battery connections on the charge controller?

My ogas in the house, pls i need ur help? Got a must 5kva 48v hybrid inverter with mppt volt range of 60 to 130vdc and VOC of 145vdc. I have 8 s of 300w with ffl specs of Vmp 32.7, Voc 39.3, Imp 9.18 and Isc 9.65. What's best way to connect it. Distance from roof to charger is about 15m. Installer recommends 2 strings of 4 s in series then parallel both strings. Also wud a 6mm solar cable suffice or its too small? Thanks for ur help.

2s4p considering you have just 8

If adding an extra is not going to be an issue,
3s3p

Thanks. My fear is its dangerously close to the VOC. Also what wire guage wud u advice?

Drgreatone:

If you are running high voltage, your wire gauge becomes smaller. For this application 6mm is okay.

However if you will be upgrading in the future, you might have to factor in cost of wires

Drgreatone:

39.8 * 3 = roughly 120v.
39.8 *2 = 80v roughly.

Running 4s is a waste of one to me from experience.
So choose your fate accordingly

All I need is wire guage size sir. Pictures bawo😄. If you want to carry 80amp from Charge controller to 12v system Battery. How many mm wire will sufficiently carry 80A. Battery distance to controller is less than 1yard. Thats what I am asking

25mm+

Obnoxious2001:

25mm+

Will 25mm wire be able to enter those small small holes that most of these MPPT charge controllers come with. Cos 25mm is quite thick

You have to force it.

But yes it will

Pls what do u mean by running 4s is a waste? Is it cos of the VOC?

Why are you running 80amps? That's a lot of current for an SHS.

Well if you must, then use a cable ferrule to terminate the cable before connecting.keep close watch on temperature of that setup too.

10mm x 2 if u want to manage

Trippledots:


Did you configure it for tubular battery?

Nope,I assumed it would detect it's a 24v system and automatically adjust just like it said on the manual.

Can I message you off of here please? Cos I am thinking the cc is faulty at this moment,my battery was very very low prior to that and when the cc wasn't charging it,I had to disconnect and use a generator to charge and when I plugged back into the cc,the case was still the same thing.

@icjunior

My batteries were very low during the time I made the initial post,soI had to use a generator to boost it for 3hrs.
And after the boosting, the cc kept functioning the way it did earlier.

Oh lie oh seas lie lie lie five sea five one

I hope you are able to decipher it

Don't no what kind of system u want or d size of ur load, ur location will determine cost of materials but u can get some items off this thread
Lifepo4 battery from Valto
Jinko , I'm sure u must av notice someone posting that here
SPD MCB DB n cables from zeestone
Etc

Hey Guys

I'm planning to set up a solar power system to charge two 24V, 150Ah batteries during 8 hours of sunshine.
I intend to use a 24V hybrid inverter. I tried SMK but it packed up in months.
Can you suggest the specific components I'll need to buy, along with their ratings, to achieve this?

What happened to the smk? What was the setup like with it in of protective devices/s seeing as its just the inverter that got bad and needs replacement from ur submission. That wud help in advising u further.

Jefferyzz:
Efficiently? Yes but it will charge nonetheless
I may agree with the person cause
1. Ure on a 12v system n ur working voltage will likely b below d required voltage that's needed for ur mppt to work(thats if ur CC is mppt), so ur mppt will function like pwm
Are u using a lead acid battery? If yes, ur battery won't get to float with just 1 300w n u will soon start noticing capacity drop

Decided to go with a 300watt but does any one know if I can get a mppt charge controller less that 40k?

Thank you for coming through boss!!!!!
I really appreciate.

I ed him but the prices have almost doubled because of naira depreciation. The one of 140k two months is now over 270k.

Hero2t:


No, it won't. Try reach out to @cooldipoMPS like @Trippledots recommended. What he sells will work perfectly for you within your budget. His . 0 806 531 6307

Cheapest is 90-100k
