I ran a 1hp non inverter AC pulling about 750w, electric kettle pulling about 1400w, Mircowave pulling about 900w and other loads like ceiling fans and bulbs simultanously, on the battery i was pulling about 64A~66A, all this was powered for a few minutes each cell were at about 3.388v with the highest at 3.399v but after the load went off they gradually when back up to 3.452~3.453v.

For the first time putting my inverter on a 72% load. I guess i will not be trying this any time soon again.

This is my cells right now, I guess they are well balanced.

ask4bk:
55.4v is low? Omo 😁😁. That's 3.46v which is over 90% of full charge. That's a very ok charge voltage.

Don't forget that LFP maintenance are rated based on 25ºc. That's temp for summer in Oyibo land. I'm Nigeria that's a cool temperature coz 90% of 365 days in naija we are above 25ºc ambient temp not to talk of temp of cells in the park as calculated by bms.

Where i stay ambient temp gets to 42ºc. If you charge regularly even at 3.5v in our high temp you are reducing LFP lifespan. That's a fact.

I always set active balancer to start balancing from 3.4v. My max charge around 3.46v. You'll not gain anything from 3.5v to 3.65v apart from heating ur cells and reducing lifespan.

Hello Everyone, please can anyone guide me properly? I use a Felicity IVEM 5048 inverter, with a LIFEPO4 15kWh DIY battery, and I noticed that the Felicity inverter has only two charging stages: Bulk and absorption charge. but in the setting, what is confusing me is that it states Battery C.V charging voltage and Battery floating charge voltage.



When I set the float charge, it works as the absorption charge value, so will I be right to say that the felicity inverter does not have a float charge stage under the LIB? Please see attached for what I am trying to explain.

where is the age limit quoted

It has age limit, not all are eligible, let me apply master for my wife, since I can't....

If you are above 35years, it's not for you, they are looking for young blood😆 😂 🤣

I am at the stage of taking the English test, it will last for 30 minutes.
Anyone with an info on how simple or tough is the test?

I want to apply but i do not know where to start from

why don't you buy a 6kva 48v system instead of 24v system, also what is the make of the inverter

please drop that idea of getting 300w panels, why not go to fouani and get a higher wattage and half cut technology ( you can get 6 panels of 620w Jinko panels from Fouani @ N138 900 which is better than the 12 panels of 300w that was quoted for you), that will also be a tier 1 panel.

so all this you have mentioned is a case of not doing a proper energy audit and system sizing. I have been fully off-grid for close to a year now and it took me back to the drawing board to do a proper energy and system sizing, I can confidently tell you that i power every appliances normally being powered by NEPA with my Solar energy system, come rain come sun i am having 24 hrs of power in my house.

nurudeen181:
But it doesn't work like that, it can be better though, the important part of a solar system are the panels, everything else are a waste of resources but maybe that's what we have now. Solar today is inefficient, it's not replaceable to nepa light, yes nepa light is costly and not stable or reliable but we need stop making people believe solar can replace nepa light now because it cant.
1. When there's no sunlight, no power for you, when sunlight is poor, no stable power, when sun is at it's peak, there's limit to what you can power and the duration it can power you appliances.
2. Affordablility, how many familie can afford a solar system that will power the electronics in their house the way nepa light does even if they'll have to use some at a time and others at other times.
3. Efficiency, the panels are mostly doing great work but the charge controllers and the battery is nothing to write home about. Charge battery the whole day and at night, the charge is down and they tell you that you should have reduced load or put it of during the day...
4. Improvement, i thing a good solar generator should be able to produce sufficient power without the battery connected so that the solar generator can produce power during the day while the battery is charging and the batter can take over at night when the sun is no more. My take
And mind you, solar is not environmentally friendly. The batter is destroying the environment. This is a hard truth. The panels are fine but the batteries, no way. To make 1mah battery, a lot of destruction of the environment has happened not to talk more of making batteries in kwh. The resources can not sustain the demands. Goto germany, go to drc, china and see this effects

Please where can i watch this online

guy ditch that installer, he is used to connecting low voltage inverters and charge controllers. he is even adamant to learn

SourYoghurt:
I called him a few minutes ago, he said he did it in parallel in his words: Na 48volts dem dey connect in series.

Some installer don't read specification and that is the problem I have with them. please run all three panels in series. Also I hope he did not cut the MC4 connectors off.

SourYoghurt:


the installer claims that it was done in parallel.

connect all panels in series

Hoverbird:
Hello guys please I need advise.

I have a 5kwhr/5kva LiPO4 system(Inverter/charge controller/Battery) in a unit.

I purchased 6 units of 650w Sunter Bifacial panels. I posted the specs of the panel and my inverter system. Please what connection is best factoring in the specs of the system.

I already purchased a 6mm2 DC cable and AC/DC breaker. I want to also know if that cable size is sufficient as the recommended charge current for the system is 50A, max 100A.

I intend running a refrigerator and one 1.5HP AC

NB
========================
I intend to Add 2 more units of same panels in 3 months

I experienced the same thing in the Tokunbo panels i bought after two years and one got burnt out. After that i had to change the entire panels to tier 1 panels.

what might caused this are;

1. when you do not use MC4 connectors but rather cut the wires and do the connection thereby creating more resistance for the flow of current.

2. directly placing the panels on the roof without allowing for air flow underneath the panels.

3. using wrong gauges of dc wiring.

I will advice you to replace that panel with a new one

What could be responsible for this burn and cracks?
This is a 6yr panel but two of my panels suddenly one after the other developed this syndrome.

Is this panel by chance still functional?

Using series for 19 panels at V.O.C of 37.2v with inverter VoC of 500v is not a good thing, it will damage the inverter. if you are to ask me i will do 13 panels in series and then introduce a charge controller for the remaining panels.

Edrizz:
It is utmost impossible to have 100% harvest from ur panels, max is always 70%. So going by that u can series 19pcs n discard d remaining 6.

I doubt if those panels are original Canadian panels

what are the panels specification, if possible send picture of the back where the spec is.

prince4pro2:
I hv added two more pannels. What I hv now is highest 8a and highest 90w according to the charge controller

Bros you just said the truth, when you undersize the panel you likely experience things like this that is why I rely on the voltage rather than SOC. Once your panels are well sized and your battery get full everyday the BMS will always recalibrate.

I equally use Valto's battery and I have never experienced this because I sized my panels very well.

princely009:
Dam5reey1 clearly stated that his post is for educational purpose only.
Besides everything he said there is totally true becus i experienceed it with one of my lithium batteries just last week. The battery was barely getting to 100% SOC daily due to undersized panels and a high dust in the area.
Last week, the inverter cut off power, beeping low battery bt the display on the battery was at 48% SOC and i was surprised.
I called Valto whom i got the battery from and he told me to charge the battery until it stops receiving current and also to ignore the display on the battery even if it is showing 100% and charge the battery until it stops taking current that the BMS will recalibrate itself. I did exactly as he instructed and everything is back to normal. The BMS has recalibrated itself.
I believe Valto didn't explain all the details that Dam5reey1 went into in his post with me becus he knows I jst wanted solution and not explanations.
And before you say I am being biased myself, Valto is my plug for lithium batteries. I hav bought over 6 batteries frm him. Three (11.7kwh, 14.3kwh and 16kwh) batteries personally for myself, and more than 3 through my recommendations to my friends and installer). And all are performing excellently well.
Infact, I am planning to buy another 16kwh battery from him for a friend next week.

PS- I have oversized my panels in that location and my battery gets fully charged every day now.

Their new rebranded charge controllers are quiet troublesome. Seen people complain about it.

BigDickProblems:
I’m really seeing this Felicity charge controller as being useless and overhyped. It’s really frustrating.

Apply series configuration to the panels and make sure to use the right gauge of wire

BlueStripper:
Good Morning Bosses,

Please I need your advice before I install my setup. So i bought this inverter with this data sheet and 9pcs of 485w Jinko panels. Kindly advice the best wiring connection for maximum yield.

I was thinking connecting all 9 in series, considering the inverters Imax of 22A.

Panel Datasheet below

Pmax - 485w
Maximum Power Current ‒ Imp [A] - 13.38a
Maximum Power Voltage ‒ Vmp [V] - 36.25v
Open-circuit Voltage ‒ Voc [V] - 43.76v
Short-circuit Current ‒ Isc [A] - 13.93

Please advice me.

the green light was it flashing very fast as at the time of snapping this picture or was it flashing very slow. its likely your battery has entered floating stage.

Greetings
Please I need the help of everyone
Just yesterday I bought 4 pieces of jinko 615kw from fouani

It was installed on 5kva felicity inverter, 2 pieces of 220ah battery and 60ah felicity charge controller

The image below is what my charge controller is showing this afternoon, is this normal or is the connection wrong?

With the number of panels you have does it charge the batteries fully every day

Dam5reey1:
Na so..

DIY all the way!

Growatts 6kw
jinko 8* 550
Deriy 30kwh..

Inverter and BMS configured to my settings... Balancing set....

Thank you very much, i was able to see the error that was been complained about.

Please can anyone tell what they mean by Query raised on the Status Approval and other page i cheked the process it's saying waiting for enrollment.

Not now, the Hamattan is still hanging around.

adrusa:
Time to consider washing your panels guys.

Bros my honest opion which might not count, go and buy tier 1 panels( jinko, Longi, original canadian, Era etc)and save yourself the pain. i bought 12 300w panel that only did a max of 1.6kw, but when i manage to discard them and went for Jinko panels, its like a bunden left my body seeing my panels generating over 4kw.

ManAdii:
No reason boss. I just wanted to patronize a Nigerian brand to grow our economy.

But if I don't see any positive review from existing users I will opt for jinko.

for a 24v

the bulk/ CV= 27.6v
Float voltage =27.2v
Cut off voltage = 24.5v

[quote author=redgem post=133622493][/quote]

unless you do not mind the 615w pannel working as 280w which is a lot of lost then you can go ahead.

my honest advise is get the same rated panels and do not mix panels of different rating, but if you are hell bent of using the 615w then get an external charge controller so you can rip the benefit.

Good afternoon house

I want to make enquiry

I went to fouani office here in Abuja to get 2 pieces of jinko 615w panel to add to 4 felicity 280w panel already installed but the manager said it will not work except I don’t care if the new panel is supplying 280 instead of 615.
I called an installer and was told same thing. later, I was discussing with someone and he said I should not mind them that it will work well if I install the 2 new panel, then connect it to another face on amon the charge controller

I want to confirm from people with experience

Thanks

Order 555w X10panels on the same 20th november and it was delivered in 3days

HeavenlyBang:
You're a lucky guy.
Ordered on November 20, still haven't received. Awful service.

Check you manual its either call Charge voltage (C.V)/ Bulk voltage. then you will see float volatge too, check does settings and see what are the figures there.

redgem:
5 panels in series..... 3 475w and 2 485w... As for the bulk charge and absorb settings, I really don't know how to go about it...

Check you Bulk charge and absorb settings. Also how many panels and wattage of the panels are you using.

redgem:
Hi, good afternoon everyone...pease, I am still very new to this and I'm trying to understand how this works..... I read online that 29v means it's fully charged for lithium 24v batteries and 27v means charged but resting....my system never gets past 27v, is this okay?....
