Is this open to negotiation?

Betnomore:
Available

Hi everyone, I'm kinda new to this thread.
Please which is better between pixel 6/7 and redmi note 13(ordinary)? I'll also appreciate the reasons for any answer.

Chief, how much did you get it?

dollarnaira:
Heats up within few seconds. Bros it works like a regular iron. I was amazed. I will try it again tonight.

Trippledots:
Do a fence mount. Just make sure shadow is not cast over it during the day

Landlord said no. I might just have to use just that one.

HeavenlyBang:
Due to roof constraints, west.

How many hours of useful sunlight do you get per day?
Mine will most likely be facing 53° southwest coz of the same restraint. Hope it's good?

FEGEITOK:
I have seen people keep it by the frontage if it is a storey building.

Seen someone whose own was installed by or on the the fence here.

That may also be an option.

I pray you move to a better place

I'll consider the fence as well. Though, we have tall buildings around the house. Thank you.

HeavenlyBang:
I have the 580w. Three of them in series and get ~146v

So you should be getting around 47v from yours typically.

Averagely? That's great!! Are yours facing 0°south as well?

HeavenlyBang:
All you need to charge a 24v battery is 28v.

Oh thanks. Do you use the 550w jinko panel?
What is the average voltage that I can get within 9am-3pm daily?

FEGEITOK:
Why not put them on a car port? Why must it be on the roof?

Is there no space for a car port?

There's barely space for walking. No space at all for the port. Only choice is the roof.

HeavenlyBang:
These days you'll be getting that 250w by 8:30 am.

Hope the voltage won't be too low to charge a 24v battery bank?

Hello everyone. I need your advice please.
I have a 24v system comprising of a 3kva sako inverter and a 3.2kwh lifepo4 battery.

Load is majorly a 100w fan + 130w fridge(on for 4hrs/day)

I want to get solar panels to complement my setup but my landlord will not allow more than one panel on his roof(Lagos landlord wahala).

Will a 550w jinko panel suffice for the load of 24v/250-300 watts?

Please note that I'll be supporting with utility .
Also note that my inverter starts up at 30v according to the specifications on it.

kristien4:
My jinko 580w watts making me proud.
Rated 13.6amp at STC producing 13amps..

Is this just for 1 panel?

Jefferyzz:
Unless u can increase Ur budget. If u can, u can change to 550w

To 2 550w.. Thank you. Why not just an hybrid inverter and the panels? There's a possibility that it's amount to the same amount of not cheaper?

Dam5reey:
I provide on pages back..

Thank you boss. Your answers have been very helpful.

oweniwe:
Brand name: Smarten

Charging profile: SMF Lead Acid/Tubular/Lithium

Built in battery charger

Asking price 290k

Location: Asaba but can waybill anywhere you get it same day

Contact: Whatsapp 08104447220

CC: Chikach

Thanks for the offer. Is this hybrid? Besides, I'm located in Lagos.

HeavenlyBang:
Well, you wouldn't be getting the most out of your MPPT.

For example, I have a 3*580w PV setup connected in series and I'm only getting 320w on a cloudy day like this.

Your system will work, but try and add another panel at the very least. If you don't do it now, you'll still need to later on. And it'll be more expensive for you then.

The only limitation now is space. Even for the two, it will be tight.

Dam5reey:
I have shown you a picture where charging is well with 113V and even less.
and 1.64KW panel deliver 1.47KW at that 111V..
so your 240V nominal headache I don't understand

Wow. Abeg what's the Voc of the panels and how many panels?

HeavenlyBang:
There are. Plenty.

For example, Powmr's datasheet for their 2kva and 3.2kva models.

So, no need for me to have the nominal voltage of 240dc? Na the nominal dey gimme headache.
See this data sheet as well. According to this data sheet, I can even use the inverter with just a panel right?

Dam5reey:
There are low Voltage MPPT and there are High Voltage MPPT.
you select based on your needs.

there is 100V MPPT, 2 panels works
150V MPPT, 2 panel works
30-400v MPPT, 2 panels works
60 - 450v MPPT, 2 panels works
90v - 450v MPPT 4 panels or more
120-450v MPPT 6 panels or more.

options plenty.

Do you know any hybrid inverter with those ranges that can easily work with 2 panels? What I've been seeing is nominal voltage of 120v and above.

Jefferyzz:
2 440w - 260k
1 powmr mppt - 103k
3000w easure sachet inverter - 92k
Cables n odas - 70k
Transport - 10-20k
This is most likely Ur cheapest route

What about cloudy days... Incase I want to use the grid to charge. And can those panels charge the batteries fully? Let assume I just use to 50 dod.

Dam5reey:
Hybrids are here to stay and have stood the test of time already. why are people still contemplating?
Hybrid gives you an Inverter, Charger, and MPPT, cheaper than any standalone.

example with 250K. you can have
a 3kva inverter with 60A charger,
80A MPPT, go and price stand-alone equivalent.

Hybrid allows you to customize slightly when grid charge, how much grid charge, when Solarcharge, Only Solar charge during the day and Grid charge in the night, etc. with standalone, you need to have good know-how and other tools to achieve these.

Alright. Thanks.
But can 2 500w panels start those inverters? If it can, will it charge at all?

Hello. I have a 24v 100ah lifepo4 battery.
Constant load - 240w which is just a fridge and a fan.
I want to get an inverter to match it. I'm also planning on getting panels later on.
Please note that we get up to 8hrs of grid light daily.
Is it advisable to get an hybrid inverter ?
Considering that I'm staying in a rented apartment(limited space), will 2 500/550w panels in series be enough?


Budget is 500k.

Dam5reey:
This model required 120V... If he adds one more 545W it will work fine.

the 30-400V type works with 1Panel..

And the one panel can charge a battery?

Dam5reey:
Both!
you can contact them for more information, I am not a marketer, lol

I'm about dealing with them(a rep on the flier) to send it over to my location. Just a bit sceptical.

Dam5reey:
It was shared here
https://www.nairaland.com/390522/solar-energy-complement-fta/1675#129600884

Did you deal remotely or you went there physically to pick the products up?

Dam5reey:
410W
VMP 31.36V Imp 13.08A
VOC 37.32 ISC 14.00A
108 half cell

Can you share your contact?

Dam5reey:
Sako 410w, 4s configuration. 1640W total capacity

What is the max voltage of each panels

Dam5reey1:
You can get 24V 3.2KA, 2.9KW from Sako. At similar price or even less, I just completed an installation of such

What was the configuration of the panels you used?

adibo:
I actually bought the items myself from Cocharis. I bought the inverter at dealer price, 288k while the batteries cost 240k each at dealer price also. Then the Jinko panels cost 129k each. That's about 1.155m. Then I paid for the installation

Can you share the inverter dealer's contact?

odimbannamdi:
First of all, congratulations on your set up.

I don't trust inverters with inbuilt chargers as they hardly charge batteries optimally. I speak out of experience from using 2 inverters. Most times, they undercharge your batteries and indicate them as been filled, when they aren't. Solar charge controllers are more efficient in charging batteries, under the same conditions, compared to inverters

Next, you need to be able to monitor the voltage of your batteries while charging and during usage to ensure they are always optimally charged and that you always stick to the 50% DoD rule a brother up there mentioned. The life of your battery depends on it. Get yourself a voltmeter and regularly do the checks. Or get this small digital voltmeter and have it permanently connected to your batteries so that you can get the voltage reading immediate

So, you'll recommend a separate hardware? I mean a separate charge controller and then an inverter?

adeshina36:
I use (2) 220ah battery

How long does your panels take to charge your batteries on average?

EduTechTainMent:
This is one of the best alternative energy companies I know. Kept wondering why their products isn't in the 9ja market that much. Nice one

Have you used their inverters before?
