Replacement battery for rechargeable fan. 14.8v 9.8aH li-ion.

Will provide updates if/when I receive it.

Bought a lead acid 7ah last week for ₦16,500. This would've made a better alternative. Assuming paper specs match real world spec

What's the most reliable/best 12v 1kva inverter brand to go for?
I was thinking of felicity 1kva 12v but haven't found it anywhere in Nigeria

Felicity has it in 1.5kva 12v.

Chimarto:
I Will stop SMS alert and enable email alert, we are losing a lot in this country,

Email alert is not as fast as SMS o

Good to see after 2000 pages we still have the Lead Acid vs Lithium "war". Interesting

Dam5reey1:
I dey buy the one my power reach, Will do Haisic soon

Drop video when you do. Thanks for all the work you do.

Dam5reey1:
Hmmm..
Most of them can't send me products to test..

Take one for the team, buy

dollarnaira:
Super true.
While some will need 5 Pv to achieve their aims another will just need just 2 pvs to achieve same energy.

That's the sad truth

abuzz33:
With a roof with that kind of steep tilt I wonder just how much power you lose considering Nigeria is between 6-9 degrees north of the equator. Has anyone investigated this? I have a couple of solar flood lights and noticed that tilting the panel at 45 degrees reduces power capture by at least 20%. Placing it completely horizontal captures the most power.

It is hard to change the tilt angle without a commensurate roof mount that allows for the appropriate tilt. This is one of the most overlooked aspects of renewable energy installations. Nigerians often prefer extremely large tilt angles on their roofs, especially in so-called "modern" architecture.

A lot of power is lost this way. Most of the time, you have to add more PV panels to offset these losses.

Good morning guys

I ordered a nillkin case on aliexpress since 21st April 2025, till this very day it's hasn't been shipped.. What's the way forward?

Buy in Alibaba and use third party shipper.

numericalguy:
Luminous 24v/1.5KVA
This is the type of inverter that i have and I have been using it for 8 years

This inverter doesn't die.

My cousin has one since 2015. Still rocking.

Ahyjo:
please I need a reliable plug here to get these and a good dc cable from.

@linnov8 sells good DC cable and breakers

With all the wealth of info made available here, you are still saying you dont have money for lithium. How much do you know will get you 2 nos of 12v tubular batteries for your 24v system? (Nerver forget you will use it at 50% DOD, let me not even talk about charge and discharge rate) And how much is 24v 100ah lifepo4 battery?

Some peeps may not like lifepo4. This used to be 8 years ago.

Alueheal:
Please who can recommend a good 2.5 KVA Inverter 24v and a good tubular battery brand..
I don't have money for lithium battery please take note. Thanks

Luminous inverter

Luminous Tubular Battery.

Cheers.

Ahyjo:
Please I need guidance on the breakers I need to ensure are used for a 6kw pv and 6kva inverter setup

You'll need

1) a good earth
2) a DC SPD
3( an AC input breaker ~ 32A
4) an AC output breaker ~ 20A
5) a DC breaker 600V/1000v (the amperage will be determined by the configuration of the PV with respect to the Isc)

Dam5reey1:
60A..1000w 18-100V MPPT VOC 125..
I will be testing it with 2 units of 590w panels

That sounds impressive. Update when you finish testing.

Dam5reey1:
JOYKOO + Haisic..

12V 100AH.. BT APP monitoring
12V 1.2KW with 60A CC inbuilt.. and 60 AC charger

Best budget combo... Under 500k

Combo looks good for a beginner and low budget peeps.

Please what's the inbuilt controller PV voltage specs of the inverter?

fuckboys:
You're capping rubbish, even a business minded person knows 200k is a lot of money. And average Nigerian doesn't even care about all these big names yall throw.
He only care about his battery run time and cost effectiveness that's all.

Can we disagree without personal attacks?

Thank you for coming to my Ted talk.

Zoha99:
Please guys I’m new here. I’ve ready about 50 pages or so and I’ve seen the discussions about lithium batteries which I am trying to get. From experience please which would you recommend valto (seen many recommendations here) or vestwoods ( recommended by a friend)

Valto >>>> Vestwoods

clevermugu:
as a business minded person , will u invest your 1.9m on a lower quality hithuim and wait for 3months to arrive, when u can get an Eve for 2.2m in naija instantly.

I like your username.

dayjavoo:
Hello everyone, my neighborhood recently got downgraded from Band A to Band B and the power situation is bad. I would like to setup an urgent backup.
My energy needs are minimal;

I just want to be able to keep the internet (fiber) running, charge my phones & laptops, use fan & use lightbulbs. Maybe use the fridge (and tv) with it occasionally. In fact, I don’t expect my instantaneous power draw to ever exceed 300w as it’s essentially just a backup and I can save my major power demands for the grid.

What are the most cost effective recommendations as I did not plan for this and I’m on a budget. I may not use panels for now as charging the batteries & regular grid usage on Band B are still around 70% less than band A so I don’t mind for now. The focus is power as petrol is simply unaffordable at the moment

1) 12V 1.8kwh lithium battery ₦399k from Valto or Cworth 1kwh @ ₦177k
2) 1.5kva 12v inverter from SRNE around ₦350k

Ahyjo:
Please how about this sticker? Does it seem genuine?

Post terminal junction too. These guys in Alaba are becoming smart

Dam5reey1:
Haisic.. make una buy for science and share experience
It's 200k

I see no big deal here if they have a good after sales service.

Not like one dude that bought a 30KW 240VDC inverter from China. First week after installation it got bad. He was told by the seller to return it to China for repairs

QuoteJust1nce:
Light rains, with a sun afterwards, best recipe for solar panels
The panels have maxed out their 4.6K capacity at this point

Enjoy the sun 🌞

HeavenlyBang:
Higher current means higher cable costs and higher losses.

There's a reason why electricity is transmitted at high voltage, not high current.

By connecting more panels in series what do you think I'd get? More current? Please do help answer me.

Lemme be clear I prefer to run as much panels in series as I can so I'd use lower gauge wire without issues related to the crazy current people get by running many parallels.

HeavenlyBang:
Which is weird because surely we want higher voltage than current. I think Jinko's setup is best. 550w = 41 X 13a or so.

I prefer my voltage to be lower so I can put more panels in series and not exceed a solar charge controller maximum VoC. At the end of the day, power never changes. High voltage or low current the power is still the same - 50V 10A or 40V 12.5A is still 500W

omotoda:
Maybe there is nothing to bother about then but I know my Felicity 260 w panels of close to 4 years have about 36.. something volt as VOC so I was only wondering why higher warrage will have same VOC .Perhaps the experts can shed light on this

Power = Voltage X Current

Vmp (Voltage at Maximum Power Point) and Imp (Current at Maximum Power Point) are the voltage and current values at which the panel delivers its maximum power output (Pmax). The panel wattage rating is calculated as:

Power = Voltage × Current

Vmp (Voltage at Maximum Power Point) and Imp (Current at Maximum Power Point) are the voltage and current values at which the panel delivers its maximum power output (Pmax). The panel wattage rating is calculated as:

Panel Wattage = Vmp × Imp

For instance, a 400W panel can have a Vmp of 36V with an Imp of 11.1A.

Notice that multiplying these two values gives you the panel wattage.

Similarly, a 300W panel can have a Vmp of 65V but a smaller Imp - 4.61A. Multiplying these two quantities also results in the same 300W.

Most premium panels usually have a lower Vmp but obtain their wattage from a correspondingly higher Imp. This is the opposite of most inferior solar panels, which often have a high Vmp but very low Imp.

GloryJoyeux:
I reached out to solar assistant complaining about the new deye inverter not working on it.

They responded by releasing a beta update 3 days ago to address my issue. I can now confirm that solar assistant is working perfectly with the new deye inverter SUN-6K-OG01LP1-EU-AM2.

Kudos to solar assistant team for being so proactive.

Gotta buy that Raspberry Pi and see what I can do with HA. Thanks for the update.

Jefferyzz:
If you haven't bought this panel, I'll advise U don't, that 14a U see has a lot of factor to it. 1 side facing sun might give 10-11a. Unless you install on a carport and there something below to bounce back sunlight on the other side of the panel. Bifacial panels are not made to be installed directly on Ur roof with nothing to reflect sunlight to the other side.

According to Jinko official spec sheet for their 545w JKM545M-72HL4-BDVP solar panels, you can still get up to 545w using only the front facing cells under STC. You will gain more power if it's on, say on a ground mount, where the sun gets to bounce off wall/floor and hit the underside. Attached is a screenshot of the datasheet (did a screenshot of the relevant PV for this demonstration).

Conclusion, you don't really lose anything but the "extra" which the PV panels is not rated for.

Bruteality1:
I'm planning to use 10 of these panels.

I'll hazard a guess you did not read everything I said judging by this reply. Cheers.

Bruteality1:
Is this solar panel compatible for a 48v inverter?

Solar panel compatibility should be checked primarily from the solar charge controller's perspective, not solely based on the inverter system voltage.

Yes, you can use this panel with a 48V system. However, the important questions are: How many panels do you plan to use? And what are the specifications of your solar charge controller?

Without answers to these questions, it would be difficult to provide a proper recommendation or assistance.

Cheers!

Not a fan of welded battery terminal. Great as it provides amazing electrical contact but bad for DIY and tinkering. I love tinkering

Should a cell go bad on welded joints, that's the end of the run.

The only place I may value welded joints over screw/bolt/nut terminals is in my eBike battery build. As long as I'm not jumping over potholes and rough terrain in my home energy use, not a fan of welded joints on that end.

I live for that right to tinker and repair
