Thanks man. I av been to thermocool showroom n u're correct. Price is 2x. I'll go for ac type jeje.

earthrealm:
what is the main reason you want to buy a dc freezer?.......
if its for energy savings dc freezer consumes about 70w, while ac of samesize is about 120watts.
purchase price of dc freezer is about 2x of ac type.

repairs::: would the local repairmen be able to work o them, on the off chance that it developes a fault?

would recommend you buy the type that has an ac adapter...so you can switch to ac--shud you want

This setup go far oo.. Lifepo4 or not.
12v system with 2760wh battery n 2160w panel don turn expensive shiii. The price of this 12v is enough to get any1 a decent 24v setup.. lithium or not

ojeysky:
Dropping small backup setup with 230ah lifepo4 for someone that may be considering it.

230AH 12v setup
- 4units of lifepo4 320k
- BMS 4s - 50k
- 540wx4 panels - 640k
- High V 1.5kw inverter - 110k
- Cables and other - 40k

230AH 24v setup
- 8units of lifepo4 640k
- BMS 8s - 50k
- 540wx4 panels - 640k
- High PV 3kw inverter - 210k
- Cables and other - 40k

With the above you should be good for at least 6 years (subject to natural occurrences/incidences).

Have a good work week ahead

Is anyone here using DC freezer

I wan buy DC freezers. any recommendations pls?

60a solar charger is perfect for 200a AGM battery as AGM are required to b charged at 30% of their capacity. My only concern would b d brand of ur batteries. AGMs av grade too.
Wen getting your panels.. go with a multimeter to measure the volt n amps (if u don't no aw to do dat, u can check YouTube). Do not believe wat u see on the sticker. U should take ur time. Keep reposting this till you get all d advice u need. N for every one u get. Do small research to b sure they are fact n not fantasy. And u don't need to reply every post. Take wat u need n move

Ferdiwar:
Good morning all,
Please I am planning to go green and need your input on which is a better option between flooded and AGM/SMF batteries as I plan on getting it.

With the proper maintenance (battery rotation, equalization, etc) which amongst the 2 will last longer (I can't currently afford to get a new 24v lithium bank).

Proposed set up.
1. 1.5kva 24v luminous hybrid inverter
2. 4x 350W panels
3. 60A Techfine or Powmr MPPT CC
4. 24V 200AH to 305AH battery bank.

Any other other advice will be very much appreciated

Thank you

The 60 is sharp

Ferdiwar:
Are you getting upto the 60A front the CC? Or does it also max out at 50A?

You are correct. I read something similar to what you mentioned online as regards 60 powmr. Some claim the display n actual readings are different. But powmr mppt cc is actually mppt(internal components). Techfine mppt cc is accurate. What d display shows is dsame as d figure on my bms

zeestone99:
So I had an experience with a clients mppt.

Not all these mppt are mppt.

When I got there I measured with my clamp meter. And there was a 28 to 30a difference.

The particular Mppt controller is rated 80a and it was showing 70+ Amps on its screen. When I measured with clamp meter I was measuring around 40 amps. The gap was wide. We went to his house to measure the other one of 100a and we got same result, which is around 30a deficit. Home and office controller useless just like that.
I just gave him 80a fangpusun flexmax for the office and he testified good result even in poor weather. It's expensive but then you get value for your money.

So when you get controller of unknown brands do your checks very well. Below is a picture of the said mppt.

I got mine from jiji. D guys office dey alaba. I went there to inspect b4 I paid.

That particular powmr cc no dey consistent with values of the BMS according to reviews online. I'm not using it but I once considered it b4 going for techfine.
According to what I read. Without load he go show 61a on d screen, meanwhile it's outputting around 50a to battery. So just no u're getting 50a. If u're lucky u might get full 60a. U should check out reviews on AliExpress, Amazon, YouTube n oda purchase/review sites

Techfine mppt cc has info of harvest, Lifepo4 charging profile n editable voltages plus u can use it for wide voc of up to 150vdc, even has password to settings so any1 won't come n change ur settings, app option dey sef but u'll need an adapter for that which will allow u make adjustments without touching the cc.

TechGeek777:
Please drop link for this.

How effective is PowMr 60a MPPT cc?

Jumia n AliExpress. Both are 50,500 with shipping

mctfopt:
Where can you get PowMr MPPT for 50k? Drop link. Thanks

Techfine mppt

TechGeek777:
What's the name of the CC you bought?

Breakers are circuit breakers. SPDs mean surger protective devices. SPDs work with breakers.. which means u connect it very close to ur breakers. Or better still just get fast acting fuse with appropriate rating. U'll just b ready to buy multiple fuse Incase dey blow out

TechGeek777:
Is it the same thing as DC Breaker?

If u're looking for 60a mppt cc. I'll recommend this type. I got it 85k last week. It readings are accurate with figure on my BMS. If u're looking at Budget 60a for 50k. u can go for powmr cc. But the max u'll get from it is 50a. Powmr cc is on jumia, konga n AliExpress.

TechGeek777:
Thanks a million for your direct answers I greatly appreciate it.

I still have some questions itemized below:

1. Will 60A charge controller be suitable with this system that can charge Tubular battery?

2. Which budget (50k - Max 80k) quality MPPT CC would you recommend & Amp?

3. Do I still need battery charger since am using MPPT, if yes how many Amp?

4. With the above devices, do I still need Battery Desulphator/Desulfator Rejuvenator?

5. Which budget (50k - Max 80k) quality 300W 24v Panel would you recommend?

NB: Please I know the questions are much, but it's good I know what am going into to avoid regret!

$100 currently. Might change anytime though. Place d order now

ojeysky:
Please do you know the limit on GTB card? I was surprised a 21usd sent through recently. I thought gtb stopped using nairacard

GTB card
Gomoney card
Payoneer virtual card

ManAdii:
Please how do you guys shop from Aliexpress.com?
They keep declining my ATM card.

Directly without PayPal

Juror:
You use it directly on eBay or via PayPal ?

It works on AliExpress and ebay. Avnt tried Alibaba

Enyinne:
Does the gtb card work with Alibaba.com

I guess most people don't no that GTB card dey do 200. I don make purchases of $100 with my card this month. At times it won't work. Give it few days n try again. Infant try it now.

odimbannamdi:
Bros, sorry to ask, you follow us dey this Naija?

Just place d order. It will go through.

microgiant:
Bros, Please how do you spend $200 on you GTBank Cards, share the secret.

I also noticed him. It's a 30/70 chance he'll deliver. Some people claim he's too new to b trusted. He's less Dan a yr on alie. Most of the good reviews on page are US buyers. If he doesn't deliver within 3months you can ask for refund. To b on a save side. Use GTB card. Message him to split ur order into 190$ and 32$ so you can use 2 different GTB cards to make payment. U cant do more than 200 on ur GTB naira card n Rate is 495/$. So if he doesn't deliver. Ur money will b returned with the same rate.
This is my opinion

ajabani4allah:
I saw this lifePo4 battery on AliExpress, the 4 pieces goes for just $222 with free shipping fee. There are about 10 reviews on it and are all positive thought none is from Nigeria. Pls advice me on this. Can i place this order, it looks too cheap for the price

Those are Lifepo4 cells. Some come with 3500, 5000, 6000, 7000 cycle. D 3500 cycle if charged n discharge daily should get u somewhere close to 10yrs. U can contact valto on this thread to buy some

Intellab:
I learnt some batteries last up to 10 years.
My batteries are no longer holding charge. I use solar. How do I revive them?

God bless you. This will really save me the alot. I think it's 50k or thereabout
[quote author=bbally post=114755221][/quote]

My budget no carry epever. Nah y I dey look for 90-100k type

zeestone99:
Oops my bad. Can u do epever 60a.
125k

Yh. That's the point. I didn't really carefully check out the sticker. I just carry multimeter n saw it was between 43.7-44.2v each n I guess it was due to the intensity of d sun at each test periods.

Namzy:
Producing 380w from 400w even with tier 1 panels depends on a lot of things and is asking for too much. Meanwhile your panels from the specs are not even 400w. Why do our people keep doing this fraud? If you multiply the vmp and imp, it gives you the panel watts eg below. Infact I'm beginning to doubt your panels specs is even up to 330w maybe that's your problem all along and your panels are not hitting the voltage required for charging all the time

Got them for 78k

earthrealm:
the advice supplied by TheBestGovernor: while being theoritically correct, is not relevant for your scenario, i guess he didnt read all ur posts to undertsand what is going on.

then @ poster, this ur panel is a fake one, the true capacity is 330 watts, not the 400 watts sticker they put on it. hope u bought it less than 80k

I just checked the datasheet of this. Is it's 15-95vdc input n 100vdc max for 12v. My pv is 131vdc

zeestone99:
Must mppt 60a - 100k

Call/chat - 08117398294 to order

Thanks man
1. My inverter manual states 14awg cable since all panels must b in series.. i used 8awg just Incase I av any reason to go parallel
2.i did. Each had above their normal volt but not up to d stated amps. I guess it's due to the sun's intensity.
3. I checked the mc4 twice just to b sure the metal inside are out enough to make firm contact
4. I don't no of this orientation thing. But I nailed my panels where dey focus on the sun. The other side of the roof cant receive enough sunshine as it not facing the sun directly unlike the side I placed d panels
5. It's a 400w panel n I know it won't produce less than 380w. I attached d picture of the panel
6. No damages.
7. I reduced it to 40a already. Still won't go above 30a wen it working at full power. N it only for few minutes sef. It goes down to 12a afterwards.

TheBestGovernor:
Before you buy a new charge controller, have you actually found out what the problem is?

1.What type of cables and cable size did you use for the installation?
2. Have you tested the solar panels independently? - Test them in pairs to see the performance since your current inverter can handle the voltage range, test the solar panels independently with multi-meter to see voltage output of each.
3. Are there loose connections between your solar panels and your inverter? - Check all the connectors, confirm your MC4 connectors have proper contacts.
4. What is the orientation of your solar panels? - best orientation for Nigeria is True South if your solar space can be titled in this direction, Optimum is between True South and South-West.
5. What type of solar panels are you using - are you sure your panels are actually rated at 400W - many dubious solar panel sellers in Nigeria print labels for low rated panels as high power panels?
6. Inspect each solar panels to see there is no damage(s).
7. Does your charger have a setting for current limit? Have you confirmed the limit was not adjusted to a lower limit?

Eliminate all these one by one to see if you can locate the problem.

After you have done all these, then you can decided whether to buy a new CC or not. I can see some people are against hybrids, but good hybrids will save you the headache of overcharging your batteries if you use public utility + solar charging as an option.

God bless you. I'll go for d 80a variant then. It's 105k. That 1 can take 1100w

earthrealm:
I personally dont like the felicity cc, cos it doesnt log daily solar harvest.

The one you posted above appears ok, hope you saw the 800w solar panel limit @ 12 volts. Since u have 3 pieces of 400 watts panel, thats 1200 watts on a good day. most decent cc will throttle down the harvest on super sunny days if perchance 1200w comes in, some poorly designed cc may get damaged.

The cc you posted above is not a common or popular make, so i dont know how it would behave.
Alternatively you can consider buying 2 pieces of the cheap powmr cc, ie if you check the voc of 2s panels can work.

Las las..this your 12 volt setup isnt optimal, if i were in your shoes...wud consider using this oppurtunity to upgrade to 24 or 48 volts

I'm using a 12v system. powmr can't handle more than 100vdc for 12v system. I already dropped am an mppt charge controller above n asked for opinions. Kindly check. It's a 60a mppt being sold for 90k. If I don't get any suggestions. I'll go with Felicity cc den.

earthrealm:
most cheap cc cant handle above 80 volts for 12 volts battery pack.
try fangpusun separate screen cc and epsolar .
the famous powmr can only handle above 100 volts for 48 volts inverter

Yh. The down side is it requires alot of panels.

ojeysky:
12v system with CC of 80A 12v charger, are you sure about that?

Any opinion on this charge controller pls

Any opinion on this cc before I buy it

Jefferyzz:
Yh. I'm planning on getting this. Which charger controller under 100k that can handle 130vdc do you recommend.
