House I need your help with information needed so I do not make mistakes a novice, that I am, would make. I want to install a solar electrical system for my game shop and I would like to hear what you'd recommend for this setup

Here are the contents of the shop. Note that the wattages I put there are all gotten from looking at the back stickers of each TV

Lg LCD 32 inches TV 140w *2
Samsung 32 inches led 56 watts *2
Samsung 32 inches lcd TV 110 watts *2
Samsung 15 inches lcd TV 40 Watts *4
PS2 fat 3pcs
PS3 super slim
PS3 slim 4 pcs
PS4 slim 2 pcs
Ps5 1 pc

There is an ox industrial 26 inches that I use right now and a plastic fan of 60w. I plan to get rid of both fans and get both DC ceiling fans and DC standing/wall fan so recommendations are welcome pls

All games do not operate at the same time, out of a total of 6 PS3, 2 PS4 and 1 ps5 only 6 can be operational simultaneously, although I plan to add one more 32 inches tV as time goes on which would eventually make the operational games seven in number

The gamehouse typically operates from 9am till around 11pm.


I called an installer to tell me what I'd need to do the installation for the shop and here's what he recommended I do for the setup



SYSTEM REQUIREMENTS
Growatts 6kva solar inverter

Growatts battery (5.5 kW/h x2)

Jinko solar photovoltaic panels(615 watts)

ACCESSORIES AND OTHERS
1 DC SURGE (500)
1 DC BREAKER (32amps)
1 AC SURGE (500)
2 AC BREAKER (63amps)x2
1 DC BREAKER (63amps)
OTHERS:
18 way breaker box
4 way breaker box
Knife switch change over
Trunking pipe(50x50)x3
Photovoltaic panels rails(x3)
Photovoltaic panels bot 'n' screws(14)
Solar connector /MC 4 plug(2)
CABLES:
photovoltaic panels DC cable (17 meter)
AC CABLE (input) (16 meter)
AC CABLE (output) (16 meter)


Would this, assuming the items are all good quality, be ideal enough for the gamehouse?

but they have given quotes now ….10kwh battery won’t be enough to carry everything from 5pm to 11pm…cause all these loads can hit 3000w or more…..even if you think you won’t put on everything at once,,some days you will like December or holiday periods…I operate a game house/viewing center too

See eh, issue is most are used to FAKE leadAcid batteries. Back in the days when I got into Solar newly, My batteries no dey last beyond 8-months TILL I stopped buying the likes of Neptune and the rest. Quality leadAcid batteries dey wether wet or dry cell. Issue be say most of us go run from expensive ones, buy cheap Ones, then later come complain.

Once again, not saying Lithium chemistry ain't superior to leadAcid batteries BUT a low quality lithium based battery can rarely surpass a quality leadAcid battery.

For market, we dey call those fake batteries "Alaba Battery"

you are right..that’s why I said 90% of Alaba batteries…

Gshems:
When I moved from sealed lead battery to a 100ah lithium battery, It was like I was blind and now I can see. The difference is like night and day. I am currently on a 12v system but with a 4kw battery. Next upgrade náà 48v. Me sef Wan dey use a and induction cooker

bro even a taico 1.28kwh battery is better than 90% of lead acid batteries being sold at alaba

prince4pro2:
Started with powmr pwm 80a and 4 200wat used pannels. Later got 4 420w pannels (used) but connected 3 cuz of roof space, connected the 3 420 to sms mppt 60A. So far so good even as I type everywhere good so long as say sun the shine. My Airtel 2.5kwh frm cdcare will soon arrive and moving man go still the move .

sharp… the best investment is that your lifepo4 u just bought…you will enjoy it….. I use a transformer based inverter with my lithium battery (solar for charging with Mppt cc) I want to upgrade to hybrid transformerless but my problem is lightning,,I have much here during raining season and I Dey fear for the inverter..my current inverter is rugged and I haven’t even had issues since I got it even with all the lightning thunder I no Dey put am off..


I just one relate the later innovation but I Dey fear…I heard hybrid is more efficient in term of power consumption

bassdow:
your friend funny . unfortunately, checking for voltage ain't how to check battery health.

that’s because you are experienced and vast in this line

bassdow:
if person carry better battery give una now, na same Una go talk say e too cost. When I got into Solar newly, na so I dey change battery almost every 8 to 9 months till I grew sense.

The Used ones I currently use now, don't see myself having to replace them even in 3 years time. Na so e suppose be.

chief even those used batteries sef nah luck…not many of us can identify good used batteries.A friend used a voltmeter to read one battery showing 13.8v ,.he bought it thinking it’s good and clean..only for the battery to drop to 11.6v under load…Bad battery !

prince4pro2:
Certified rubbish I swear, if sun goes down it will run down if sun goes up it will go up. Na just light and phn I d use am for once sun is down

father Laud…how many panels do you use and what’s the wattage? Which charge controller? Mppt or pwm?

Sorry for too many questions

prince4pro2:
Got it Feb last year. GBM Gel battery. Just wanted to start somewhere at least

at least you have done experiments with it and have knowledge…Cause that GBM battery nah rubbish normally

Dabss:
He clearly said Gel there. They are inferior to Tubular LA so I don't even know what you are trying to say.

im not trying to insinuate anything..I missed the “gel” part..I mean we all know tubular is superior….una like to Dey too attack for here

prince4pro2:
Is Gel battery and is tired already

oh alright..how long have you been using it?

prince4pro2:
Waiting for these to be delivered. HV been on gel lead acid and na shege I d see. Although is been a year plus now. Am equally on sarchet inverter pure sinewave the type vlato sells. Thanks to cd care for there pay small small if not e no for easy for me

how do you mean by shege from Lead acid battery,,I want to believe it’s tubular battery?

adrusa:
Even if it is only one person who is saved from buying 2500W inverter while thinking that they were buying 6000W, my job would have been done. It costs nothing to be totally upfront with a customer who may not be familiar with the fraudulent ratings practice by the Chinese. I will never buy an inverter without knowing the real power ratings even if they are inflated by the manufacturers using Peak power to advertise it.

By the way, keep the insults coming, it tells me the kind of persons you are.

I didn’t insult you boss..apologies if it sounded like that…I just think sachet inverters aren’t worth the stress…

adrusa:
Your response is very interesting and deliberately misleading. It is not everyone that is an expert on the poor ethics of sachet inverter manufacturers that will recognize that a 3000W inverter actually means 1500W. I'm familiar with inverters and even I don't understand a system that inflates inverter powers using their short-lived peak output. That was why I asked you. And I expected that you will respond with their true nominal powers, not hiding under this "manufacturers' claims".

Even Aliexpress sellers clearly indicate the nominal ratings of their inverters, not just leave it to buyers to guess. This is an example from Aliexpress:

[/b]Warm reminder: Dear buyer!

Inverter 2000W, continuous power is 900W, peak power is 2000W.
Inverter 3000W, continuous power is 1300W, peak power is 3000W.
Inverter 4000W, continuous power is 1600W, peak power is 4000W.
Inverter 5000W, continuous power is 2200W, peak power is 5000W.
Inverter 6000W, continuous power is 2500W, peak power is 6000W.
Inverter 8000W, continuous power is 3000W, peak power is 8000W.[b]

When you advertise your inverters next time, please do the same. Include their real nominal outputs so that buyers know exactly what they are getting. It is the honest thing to do. And as you can see, real power is not always "half of their rated powers", it is often less than half.

oga rest abeg,,if you have complaints reach the manufacturers and not @valto the reseller….or go to Aliexpress and order…Or just go into the business and advertise your own like that….You just Dey type type type on top sachet inverter wey no get value

XPaul:
The thing is our light is very stable ( I am on band A) so i need a back-up for router and laptop for the few times there won't be light. My work is hybrid. I am not planning to go off-grid.

If 30ah is about 360watts per hour, it means that a 100ah lithium battery will consume about 1.2kwhs of grid light. That costs about NGN 1k on band A (am I right?). I think that is fair if my analysis is correct.

Do you know anyone selling the charger?

Valto sells or you can order from Jumia (more expensive)

XPaul:
Thank you for your response.

How much would an external lithium charger cost?

12v 20a is about 45k 30a about 60k….but do note that if you are on prepaid e Dey chop light o….30ah 12v is about 360watts per hour…Solar is better 2 pieces of 400-500 watts will do well with better Mppt cc….maybe 45a cc should do the trick sha…..initially it will be expensive but on the long run u will save a lot

XPaul:
Hello everyone

I stumbled upon this thread as I am trying to get a solid power backup. But omo, I can't go through all the 2k+ threads.

So currently, I have a Luminous Zelio 12V 1KVA inverter (pic attached) with 2 Luminous Inverlast 220AH Tubular batteries. However, I think the batteries are weak now as they don't last more than 2-3hours on a simple MTN FiberX router.

I want to ask if I can use a 12V LiFePO4 battery with inverter.

If I can pair the inverter with a LiFEPO4 batteery, which battery should choose between wattcycle and HumsiENK. (you may recommend any other option). I am on a tight budget and I am trying to get the best possible value for money.

Thank you

the inverter is a transformer based inverter which doesn’t support the charging lithium batteries..however as bassdow have said,,you can use solar to charge the lithium battery or get an external lithium charger…but when you connect the inverter to lithium battery don’t connect the inverter to grid cause it will start undercharging the lithium…

Meanwhile using 1kva 12v inverter with 2 200ah batteries doesn’t make sense without external charger…the ikva inverter bearly has 15-17amps charging capacity for the 2 batteries..maybe nah watin cause the luminous batteries to go bad be that..You may have been undercharging them while constantly deep discharging them

bassdow:
Actually, so long an inverter is 12v from any brand, it would work with whatEver 12v battery (from any brand) you give to it.
When it comes to how to recharge the batteries, except you intends using Solar panels, you need be sure the inverter supports Lithium based batteries. What that means is, if you intends charging the batteries using the inverter's built-in charger via Generator / NEPA / PHCN, then be sure the inverter's inbuilt-charger supports Lithium based battery (most old ones don't) BUT if you intends using Solar panels, then no issue.

As for being on tight budget, everyOne is, just came back from Enugu where the client used similar phrase YET spent over 3-million naira. na Big man cry pass

bleexInc:
Hello House, what kind of pressing iron can I use with my 6kva inverter?

you can use any iron up to 1500w,the lower the better..6kva still have about 5000w ratings….

Shebi no be laundry business? Nah once in a while ironing…I say this because of the batteries…Leads acid batteries no like heavy loads

Fremlin:
Here is the thing, the voltage from grid is unstable, but with stabilizer, I get to charge my battery via the AC input of my inverter.
However, when I try to power my load thesame time while my battery is charging from grid, my freezer in particular shuts down often.

So, I was wondering, anyway I can make my inverter not to bypass, but just charge the battery, while I power from the battery that is charged.

your best bet is to get an external charger for the battery….disconnect inverter from grid..use external charger to charge battery while using battery to power freezer

ajabani4allah:
0705 316 1079. Just tell him you are an installer because he said that that price is installer price and for solar dealer buying in large quantities

okay thanks boss

olujosh301:
That's 620k for claimed 7kwh+ but the combo could only output 5kwh+ and don't forget that he also changed the bms at an additional cost. It's not worth it for me though there are other alternatives for for 12v 280ah battery. If you're on a budget it would serve though but the longevity or cycle is uncertain.

can you name these alternatives at affordable prices?

ajabani4allah:
Yes I do

can you share?

ajabani4allah:
310k

waoh e cheap true true …where did u get them? Do u have a contact?

ajabani4allah:
I was never expecting to extract the rated capacity from the battery because of the price so, it's still very ok and it's a good buy

sorry bosss how much did you get the battery?

bassdow:
SRNE is a good brand BUT doubt that's 60Amps because I got the 60Amps and higher. That one on the image is obviously probably 45Amps or thereAbout.

Also when it comes to Felicity, better you buy from where you trust as FAKE plenty for market. Better still buy from their office.

alright boss thanks big

Hi guys I want to order this charge controller from CDcare but I need to ask before I do..

Hope say nah correct Mppt cc and not glorified pwm..

Is this better than felicity 45amps cause this is 60amp and the price difference is 4k…

I’m on 12v system o with 2.5kwh lifepo4 battery….

Your advice bosses
