Na why I say e fit be clash of egos. Abeg wetin be the difference between this two make I no go buy rubbish

which ego, na your ego maybe.

The guy na really good person. You probably entered his dm for pay on delivery e sure for me.

If it was me I would block you asap. Go jumia go buy am.

Something wey I don buy elsewhere and it will be delivered tomorrow and I'm paying on delivery if you must know. You fit go block the person wey dey sell am to me as u mumu reach

Miss those days of Niyi and co sha. 😊

Abeg I fit use this connector join 2 solar cables?, I no get tools to crimp mc4 connectors abeg.

if e too stress you, pull the cables out, manually join them well and tape it. I don do like this plenty times and heaven no fall

fuckboys:
I don connect am self come down from the roof. Which kind wahala be this now.

well me never use this before BUT should work. Just tape it using black tape, then hide it underneath the solar panel so the sunLight and rain does not get to it else you go still find yourself having to climb back there. issue be say, the symptom wouldn't be obvious enough on time. You go dey suspect something else

fuckboys:
I will leave it for a week and see how it goes. My landlord don tire for my matter.

everyday I dey climb roof.

Ai said it will work but will corrode over time and that is the only issue I see there, I didn’t tape it just left it exposed like that.

If it can handle ac current of 230v, I don’t see reason why it won’t handle dc current of 160+V under 10amps.

atimes what really matters is the current along the wire, not voltage

fuckboys:
well I don’t see reason why I need to retighten those screws over time cos there’s absolutely no tension on those wires. They just lay flat on the roof surface.

The only thing I’m scared of is corrosion over time. I didn’t tape it or anything, just left it bare like that after attaching the wires

taping is often good to avoid stories that touch. Then hide it underneath the solar panels so both Rain and SunLight wouldn't touch it. No be only rain you go worry about, sun sef go follow worry am so hide it underneath the solar panel and you should be fine

Contact @ Dam5reey to get the Haisic 24v Hybrid Inverter, then try add small thing so the remaining cash can get you 4 panels (remember to connect all panels in series this time, not the way it was on the pwm).

With these you are good to go. Then later ehen the funds are available, you can then upgrade your battery to lithium.

there's something I don't like about inverters where their AC in, AC out, PV in, etc termianls are so small you might have to cut of a lot of wire strands in other to get it to fit in. That's like reducing a 10mm cable to like 4mm. Wonder why they not using the standard connectors.

Yea I know you could use those tubes but have handled a project where the previous installer choose to cut off lots of strands to get them to fit in, rather than use those tubes which even sef...

Betnomore:
The current setup is also connected in series. My issue now is that if I get a mppt charge controller, will it significantly improve charging speeds or I should just change panels and go for hybrid inverter. If using mppt charge controller will significantly improve my charging speeds, I see no reason to change panels and inverter.

MPPT is always better than PWM. Just ensure you don't get those fakes in the market.

if I have to use PWM, I might as well size my panels relative to the battery bbank's capacity enough that I could skip the charge controller altogether.

Drgreatone:
Solar alone wont be enough to adequately charge ur batery cos of its chemistry. Reason u didnt notice like u said was because u had NEPA. Tubular batteries take longer to charge so the daily 3-4hrs of peak sun might not suffice.
MPPT would have to be a high voltage one which is rare and expensive compared to just getting an hybrid. The common blue powmr needs a max VOC of 105v for 24v battery which u may overshoot with ur 4 panels as one doesn't know their VOC

still believe issue is starting from his solar panels connection (all series), then that PWM. in fact just changing the connection type should improve performance.

CuteMaro:
Referencing your initial post, you mentioned being unable to set the bms protocol, does your battery come with communication port for such? And the inverter too? (Small battery packs and inverters almost never come with it, usually you just need to know the bms brand your battery came with, download app, connect via bluetooth or wifi and adjust if allowed)

You also mentioned being unable to view harvest data, you're supposed to be able to view that from the typical inverter interface when you toggle the u.i using either up or down arrow. (Most of these stuffs can be sorted by using the inverter manual).

For your third concern, your inverter self-consumption is quite high for a 24v hybrid inverter compared to most out there. You can try to search online to know if this is normal for that brand of inverter.

My inverter do have some data as per PV array voltage, PV array current, PV array power and load.
But it doesn't log the data it only display instantaneous values only. I cannot view the past events, graph etc.

please I need input. My sister is trying to set up a phone charging business. Her budget is 700k and she needs a lithium batteries for peace of mind. Abeg how do we go about achieving this

hmm @ 700,000 naira

Let's see what's possible.

Personally, even 500,000 naira is possible BUT you not me, and don't seem like you could do what I could so let's see what's possible for you.

Forget about Lithium batteries due to budget. Don't feel bad, quality LeadAcid batteries still serves you well. Many of us still use them.



NB:
1. The charge controller is only required if the inverter is not hybrid.
2. The external charge controller should be MPPT
3. Prices of items above, except surge protector and Circuit breaker, are for used ones.
4. If you choose to use sachet inverter, then you save much more money.

4pcs 350w Solar panels @ 40,000 naira per panel = 160,000
2pcs 12v 200Ah batteries @ 150,000 naira per battery = 300,000
24v 3.5kva or 3kva = 150,000
1 Bundle of Made in Nigeria Cable = 018,000
1pcs DC surge protector = 009,000
1pcs Circuit breaker = 007,000
1pcs 40A / 60A charge controller = 056,000
installation = DiY + disturb those that allow you to.

Wow! Bros used batteries for 150k? And it isn't lithium, she will definitely scream my head off

Haykay2001:
Make she manage am reach 1.2 or 1.1M ... So that she go fir run am 24v and upgrade small small later.. That 700k will only get her 12v system..

She no get , even self she deep hand for our last born money wey want japa. Cos the bro they save the money for her hand

And bros that 4 panel set up won't work because you know Lagos shops na, as e dey small. Her roof fit risk 2 panels without irritating the neighbors

Boss let's prioritize the panels and inverter, since she will close early at night. Thanks my questions plenty

Me I dey wait for response from you since ooo

dollarnaira:
Why u no wait for response before you climb up? Pele

Seunmuham:
please I need input. My sister is trying to set up a phone charging business. Her budget is 700k and she needs a lithium batteries for peace of mind. Abeg how do we go about achieving this

Since usage is mainly for day time and on your strict budget, consider this:

* 12v 3000w (1500w continuous) pure sine wave sachet Inverter (Contact Valto or IInnov8)

* Powmr 60a Charge controller aluminium body type (contact Iinnov8)

* 2 panels preferably Jinko 525w or 530w,as you said (connection would most likely be in parallel because of voltage limit for 12v system)

* Cworth 12.8v 100ah Battery (contact Dam5reey)

* then use the remaining money to sort out accessories and installation

Cheers.

Will the set up be installed in a "shop or house"? Does she live there too?

How do you prevent it from burglar?

Seunmuham:

don't allow the Lithium evangelism happening in here make you think leadAcid batteries are bad. See eh, a quality leadAcid based battery is so much better than an inferior Lithium based battery.
Only go for Lithium based batteries if your budget is okay and you trust your source.

Persoanlly, I still use leadAcid based batteries and I run a load of over 30kva @ 48v and about 4pcs of 150ah batteries @ 12v

Also if she so much love Lithium based batteries, she could always increase her budget now or later. your entire current budget can barely get a small low quality Lithium based battery.

nowAdays, thanks to thhe Lithium evengeliism, most are selling off their [quality] used leadAcid based batteries to buy a not so quality Lithium based batteries.

Seunmuham:
She no get , even self she deep hand for our last born money wey want japa. Cos the bro they save the money for her hand

Hope the business is located in a place with enough traffic and already running so She's able to recoup this capital

Seunmuham:

it would work. They are not that big except you looking for excuse opportunity to further drop costs.

Seunmuham:

You mean She closes when the Business is about getting started. Well you free to use 1 battery in that case. Quoted 2 batteries because of those that work into the night + also accounting for days of bad weather or rainy seasons. BUT if you dropping battery to 1pcs, retain the panels at 4pcs.

Seunmuham:
shop and she doesn't live there

wow

is this a small shop not often as tall as a standard Fence or what ?

if the Shop seems like it's less secure, and probably a bungalow low enough it's probably shorter than a standard bungalow building, use sachet inverter so she could often carry it while going home BUT issues would be batteries in which case, we mighht havve a reThink

dollarnaira:

especially the batteries which is hotCake anywhere

Very good question

Seunmuham follow this advice or alternatively,

Get an Itel power tank 1kwh comes with a 500w inverter all in one system for 304k ( inbuilt lithium battery )

1 500w panel at 100k ish.

It's a very good and efficient system. Do more research on tiktok and YouTube.

You can unplug and move at the end of every business day, but e get small weight sha 😂

I think it will be perfect for phone charging business.
