LG, I may be biased as I use LG.

Their Dual Inverter model is just so energy efficient.

Maximum cold running wattage <= 1000w for the 1HP version (drops to around 600w when room is cold)

Dehumidifier mode = 230w to 600w (depends on time of day; outdoor temperature)

Fan Mode = 120w

1000W is quite high for a 1Hp AC.

Does this dehumidifier mode cool the room?

HeavenlyBang:
My Hisense as well.

Which of the hisense because the feedback I got from I got from one guy who jse the product was not so wonderful.

Which model is this boss?

mctfopt:
Red temporarily indicates the cell with the lowest voltage. This is dynamic and changes as the active balancing is in progress.

OK thank you.

The BMS does this on its own or do we have to manually activate this?

Hello Boss,

Why is one of the battery showing red?

Thank you

Hello everyone,

I drive a 2009 Honda Civic and I’ve only used it about four times over the past month and a half due to frequent travel. Lately, I’ve been experiencing a starting issue — the car won’t start unless I jump-start it using my neighbor’s battery. Even after driving it for several hours, once I park it overnight, it still won’t start the next morning.

I’m unsure if the battery is completely dead and needs to be replaced, or if there might be another underlying issue. If it’s likely a battery problem, I’d appreciate any recommendations on a good replacement battery to buy, including price if possible.

Thanks in advance for your help!

Are you sure something is not draining your batteries. Maybe some lights e.t.c

You might need a good rewire to check for you..

Dam5reey1:
AI and Theories everywhere..
Make una dey try test and show workings.

Never depend on what some inverter display shows. For PV generation.

Tested 2 inverter:
one overstates PV input while the other slightly understate PV input

Please how can i get this meter?

Pictures and location?

Hello Guys,

I drive an Honda Civic 2008

I noticed that once in a while when i put the gear in drive or reverse, I notice a vibration for about 3 seconds but its stops immediately and the gear selects well.

What could be wrong?

GloryJoyeux:
Hi,

I believe these are not real time figures, most times there is a 5 minutes refresh delay. And sometimes it doesn’t refresh all the figures. So it probably didn’t refresh either the pv or the battery charging figure.

You can try refreshing again in 5 mins, alternatively, you can confirm physically from growatt inverter.

This is why solar assistant has an edge, it provides live monitoring information and not at 5 mins intervals like most inverters do.

PLease how we get to use the Solar Assistant with our Inverter?

Do i need to buy a different module aside the one from Growatt?

Coolcash1:
Nah! I’ll rather wait for stock split. Truly, Agriculture is a hidden gold mine and that’s why I have been mopping Ellah lakes every month for a long term play.

When you say stock split?

Does it mean after a while they would divide the shares and the price would fall?

HeavenlyBang:
Recommended charge current - 40a. 40/314 = 0.127c

Recommended continuous discharge current - 75a. 75/314 = 0.238c

Thank you

HeavenlyBang:
0.13c recommended charge current and 0.25c recommended discharge are brutal.

Please how did you cal to get the bolded?

Thank you

emmaodet:


When you come, you come to your senses

Boss

Thank you for all you do..

Since i started following you on NL is being blissful.

I read your story about your family, i would just encourage you to be prayerful and try to shield yourself from your extended family.

Have being following your recommendation on stocks.. Am looking forward to more..

Thank you

Please what is TIP?

Please how do i claim my dividend payments?

Dam5reey1:
BIY installation completed

You are a chairman oo..

Kayla does not have this item is stock again..

More grace and thank you for all you do

God bless you

Sorry what type of adaptor did you use on the batteries because my Growatt does not have this?

Thank yoj

NL1960:
The branch staff will even start convincing you to open a Fixed Deposit instead.

Exactly how they convinced my mum.. And all my discussion about MMF didnt fly again.

Ferdiwar:
Does Deriy have packs with EVE or Catl cells or they only use Hithium cells?

They have packs with all of them.

Just depends on the battery size..

Dedynast:
I have 2 Pcs available... I bought them from Future last week but they do not fit my car's headlight sockets.

Still unopened. Found out they do not fit while trying to read how to install.

Available for 10k each (Bought from Future at 15k).

Location??

Haykay2001:
Not sure PV is connected to that set up.

Look at the inverter closely, you Wont see any PV in there...

He also label it as powerbank..

More like use light charge and discharge.. 😂 🤣

Maybe the installation has not being completed yet.

Would still like to know, which is better hutuim or EVE Cells.

I keep seeing them in some products catalogue

Dam5reey:
My Cells are almost 4 years and this is the pattern I have been preaching. Me I charge as fast as possible and to Voltage that get my cells balanced.
100-20% on point, see attached is 30 days pattern, mostly charged and discharged to 20% range and cycles continues.
My Cells already Paid themselve and I still have as much as 95% capacity.

Which battery product is this?

GloryJoyeux:
Hi again, sorry another long read.

I noticed some folks, especially those who have solar installed in an area with good grid availability and don’t mind using the grid to supplement their battery charge, usually only discharge their batteries to around 80-50 percent.

Some others do this because they believe they want to pamper their batteries.

It’s a bit counterintuitive, but both research and real-world testing with LiFePO₄ (LFP) batteries show that:

Deeper discharges (like going from 100% down to 20%) can actually give you more usable life than shallow ones (like 100% to 80%), especially when you look at the total energy delivered over the battery’s lifespan.

Now, I don’t mean you shouldn’t size your battery storage for poor solar yield days, but, even if you have double the storage capacity you usually use daily, you should intentionally allow deeper discharges some days.

Energy used now is the best energy, not a future promise (cycles). And the reality is that most of this cycle tests are done in a lab with compression. And either ways you loose capacity (ah) gradually till it fades to End of Life at 70-80 percent of original rating. Calendar aging is also a major factor to consider.

Let me explain why that happens:

⸻

What Most People Think:

“If I only use a little of my battery each time, I’ll get more cycles and the battery will last longer.”

That idea makes sense — and it does hold true for some chemistries like NMC. But LFP works a little differently, and it depends on how you define “life.” Is it how many times you can cycle the battery? Or how much energy you can actually pull out of it before it wears out?

⸻

Here’s What Actually Happens with LFP:

1. Shallow Discharging Isn’t Always Better
• LFP cells are happiest when used in the middle 60–80% of their charge range (say, between 20% and 90% SOC).
• If you’re only cycling from 100% to 80%, you’re:
• Not really exercising the battery
• Letting calendar aging (just sitting at a high state of charge) take over
• Getting very little usable energy per cycle
• Missing the chance to reset internal chemistry through normal cycling

2. Deeper Discharges Make Better Use of the Cell
• Discharging from 100% down to 20%, or even 90% → 10%, allows the battery to go through its intended charge range.
• This leads to:
• Better energy throughput per cycle
• More value from each cycle
• Still staying within the safe voltage range (2.5V–3.65V)

So while shallow cycles may give you more charge/discharge “events”, they deliver far less actual energy, and they may age the battery faster due to sitting at high voltages too long.

⸻

Real-Life Testing Shows:

Discharge Range Depth of Discharge (DoD) Cycle Life (to 80% SOH) Lifetime Energy Yield

100% → 80% 20% DoD ~15,000 cycles Low lifetime energy yield. Calendar aging will get to it before then

100% → 50% 50% DoD ~8,000–10,000 cycles Moderate lifetime energy yield. Calendar aging will also affect this.

100% → 35% 65% DoD ~6,000–7,000 cycles High lifetime energy yield

100% → 20% 80% DoD ~5,000–6,000 cycles Very High lifetime energy yield.

So ironically, 80% DoD gives you more usable energy over time than 20% DoD, even with fewer cycles.

⸻

Why Very Shallow Cycling Can Be Worse:
• The battery never resets chemically — it stays in a narrow, high-SOC zone.
• Oxidation and side reactions build up near the top (especially 90–100%).
• Calendar aging becomes dominant.
• You’re basically wearing it out without really using it.

⸻

Best Practices for LFP Longevity:
• Try to operate between 90–95% charge down to 15–20% — a good balance of depth and safety. (Pointless charging to 58.4v! 55.2v to 56v is very ideal for 16s (divide by 4 or 2 to get figures for 24v and 12v systems)
• Avoid leaving the battery parked at 100% for long periods. Like 24hrs straight with full charge voltage (cv)
• Let the cells “breathe” — regular charge/discharge cycles are good.
• Don’t be afraid of deep-but-reasonable cycles — LFP was built for them.

⸻

Bottom Line (TL;DR):

Shallow cycling sounds safer, but with LiFePO₄, it’s often less efficient over time. If you’re always going from 100% to 80%, you’re aging the battery without getting much out of it. Deeper cycles — like 100% to 20% — may reduce your total cycle count, but they deliver way more usable energy over the long run.

Thank you very much for this information

If i get you appropriately,

You are saying its safe to use our Life04 battery to 20%..

Also, What is better EVE cells or Hitium?

Trippledots:
Some BMS allow for parallel connection to increase amperage.

This man get time for NL today..

Its being a while.. Hope you good boss?

eben123:
I run monthly investment with them, I'm actually looking at running the 6months investment plan after my current investment expires in few days time....

Can you share your experience?

Also, What is the interest rate like?

ojeysky:
Simply put, full bid happens when people wants to buy but no one wants to sell

chimex38:
On Bid: Demand to buy a stock is so much that a long queue has been created and yet little supply quantity from sellers at the moment.

Full bid: Demand to buy a stock is so much that a long queue has been created and yet no supply at all from sellers at the moment.

Reverse is the case for offers and Full offers.

Thank you very much

ojeysky:
It could be true o, because I just saw their financials and it's amazing. They moved from 750m loss to over 8bn profit with EPS of over 5naira coming from -2 naira.
It's almost on full bid already sef, so likely people have gotten insider info

Please what does full Bid mean?

Dam5reey1:
High frequency, Natural cool no fans

Please what is the difference between low and high frequency inverters?

omotoda:
Bros thank you. I just ignored because it amazes me how people openly want to extort people on a platform that isn't a sales thread. A lot of people on this platform join to see how they can commence their renewable energy journey with reasonable cost and yet some Shylock will brazenly come here and post these outrageous prices.

I know its retail price but I just ignored him ni!

Are this hybrid inverters very reliable?

Hello Sirs,

Please can you recommend an Hybrid inverter with Pure Sine wave output. I present use a 24V system.

CC Dam5reey1 Heavenlybang

Olamlag:
Was thinking of doing the module authentication from there website before accepting the delivery, for the jinko I was thinking that the transportation will be costly since it's a bigger size because I will have to transport it from lagos to osun and also it will be way pass the max pv array of the inverter which is 600 watt. the inverter is suppose to have 80ah mmpt

Buy directly from Fouani they will take care of the delivery for you for orders above 250k.

However, even they charge you am sure it would be cheaper than the regular cab

Dam5reey1:
Yes for sure it will make an Impact. I was able cook and Microwave at the same time, even with my going to 4 years 5kwh LFP Batteries.

If there Sun and batteries are full the Hybrid HV Inverter is happier to Supply Power from Panel Directly to Load.

Thats 2.13kw from 6X 440w panels, Battery was almost full

Which Hybrid inverter is this?

tianny:
Thank you so much for this. So, what test can he carried out to know if the sperm is infected? Also, what drug can he use to boost?

Same sperm test but with the test would be called Sperm Test with culture.

He needs to be checked to confirm if there are no underlying health conditions that caused it.

Am not a doctor please. Just following this thread has helped to understand some basic things
