Hello House; kindly assist.
I have an inverter setup with 2 Amaron quanta 200AH battery and 1.5kva luminous inverter that I have been using for about 18month now. I use nepa light to charge it.
It use to have backup light of about 6 - 10hours when I started using it. My major load is my 65inches TV and 3fans with bulbs.
Now, the setup get fully charge in less than 2hours and get drained in less than 2hours.
What could be the problem.

Amaron quanta is a unique battery, but many dont care to understand it, and hence they damage it.
It requires bulk of 13.7volts and float of 13.5volt....this is clearly written on the body....unlike normal sealed batts that require 14.5volts bulk.

The dumb luminous inverter you are using doesnt hv editable charge voltage settings and outputs about 14.3volts......
Hope u see where am going

How can one measure number of cycles already on batteries?

Not possible now with present known technology...
Its like trying to know how many kilometers a used car tyre has been driven..

solar system installer in Edo state here or any recommendations will be needed pls

Whats your installation plan like?..complete system fresh install or tshoot old install?
What area in edo state..may have 1 or 2 peeps to reco

swagifted:
E be like ur battery de very large or u get abundance of nepa... Cause the cycle is quite low for the duration claimed.

In the village..just fridge..and lights, fans etc...then sumo once a week.totally offgrid.14kwh 48v.

Even if the cycle count was triple that..say 500cycles in 3yrs....thats still 12yrs minimum before degrading to 80%...even if you assume the minimum of say 2k cycles

dollarnaira:

Super true. That 80% part is the real gee.
Imagine cycling sth for 8yrs only to degrade to just 80%. This is what tubular users dont know. In directly LifePO4 is almost for Life.
In Waec 80 to 100% is A1.

Yeah, thats why i find it funny people putting so much emphasis on lifepo4 cycle life ..3k, 6k or 10k cycles...e no too get head.

My first lifepo4 pack will hit 3yrs in oct..and has about 178 cycles....so in 30yrs..will still be less than 2k cycles...so why shud i bother my head about whether its 3k or 6k or 20k cycles??

Any normal lifepo4 pack will easily do 15yrs.....and am sure within 10yrs...newer technology would hv even come out...that many may consider reselling their lifepo4 pack to upgrade

TechGeek777:


I know many won't agree with you, but they can't know more than the manufacturer anyway.

2500 cycles is expected at 43°C - 47°C.

Since the average weather in most part of Nigeria is 27°C - 40°C, we should expect (2700 - 4500 cycles); this result in 7-12 years if cycled daily.

hope you remember/know that the battery doesn't die after this 6k/4k/ or 2500 cycle count, rather its derated to 80% capacity...which is still a hell lot

I used boaster to start a 12v hybrid inverter for a client this morning. The lvd shut down the system last night but the inverter refused to wake up when the sun comes up in the morning.
When I checked the settings, the inverter lvd was at 12v and I've already set the bms low voltage cutoff to 2.5v and I confirmed it.
What could make the inverter not to wake up?
Does anyone have this experience?

so the inverter is a hybrid, solar panels are connected to it?. whats the make of the inverter, whats your UVR setting?

ojesymsym:
That is the value it was set to o

Ok, so the bms didnt obey it?.
If yes..then its time to replace the bms...who knows what else it may choose to disobey some day?

ojesymsym:
This is what my JBD BMS is reporting, what do you suggest I do based on this?

Whoever built this pack no try.
The bms shud hv been set to hv 3.6v as cell hvd on the bms, not good for lifepo4 cell to cross 3.65v.

The jbd has low balance current and it may take upto 1wk to correct the pack, if u configure it properly

AmakaRuby:


Does the welion 4.2kva inverter come with 120a cc or you bought a different cc? Asking because the one I bought is written 80a cc

this is a 3.2kva/3kw 24v inverter that you bought, not a 4kw 24v as you think...return it and get a refund or get the correct inverter...the people in that shop are opportunistic rogues

Mtn wan finish my finances ... i will subscribe to 20gb, its won't last 1 week ... i started becoming broke and at a point, my wife dey give me one kain eye whether i dey get another wife outside ... not until she got to know say na mtn ....

Now, I use the Airtel 5G unlimited internet .... speed based ... limited to 20mbps ... and January alone, i used over 650gb (I was carrying some stock footage packs, my wife was enjoying facebook instagram videos, my son streaming youtube 247) ...

All this for 20k monthly .... Waaaaaaay berra than the shege barawo mtn dey do us!

They also have 40mbps for 35k and 60mbps for 50k which i don't need for now!

Does it switch to 4g, if you travel with it, to a 4g location

Thanks so much I appreciate.
The only problem na say over little thing you wil have to talk and talk before she understand

Lolz...your brain actually knows what to do, but your heart is looking for support to do the other.
I believe u are above 30yrs...the age gap is much, and the avg nigerian girl below 24yrs wants to taste life, hv fun, party, etc....you are a stumbling block to this girls dreams, and she would be resentful towards you, for preventing her from enjoying her younger yrs to the max.

Have a final candid talk with her and free the girl and move on with ur life....if and when she has enjoyed life...and comes back to her senses...other men will wife her

Experts in the house, kindly proffer your advice concerning my inverter setup.

I have a 3.5kva SMK Inverter with two pieces of Cworth Energy 2.5kw Lithium 24V batteries (as seen below) and four 380w PV panels. On Wednesday afternoon, the inverter let out two loud sparks and started displaying error code 09 (this would be the second time within three months). A technician suggested that the inverter may not be compatible with the lithium batteries and suggested I replace it with a 3kva Felicity
brand.

Does anyone have an idea on which inverter brand will be most compatible with the batteries?

Thank you.

The installer is very very ignorant..

Smk inverter can and has been used with lithium battery.
Do you have solar panels attached to the inverter?.
Your installer likely didnt programme the inverter to work with lithium battery...hence the internal bms of the battery tripped off while the inverter was working, unexpectedly cutting off supply.

2nd the way he looped the 2 batteries is crude and improper, best to get a busbar and send each battery there...then the inverter will pick up from same busbar

gadgetplanetng:
This happened again today and the weather is really sunny

I put on the inverter and it was around 27.6v

Connected to the house and the solar charging went off but battery was still draining

I turned off the PV breaker, the inverter then the battery

Turned on the battery breaker,

turned on the inverter it was 27.6v

Turned on the PV breaker, it started charging

When I put on the load in the house, the battery voltage ran up to about 28v plus then the solar charging line went off again

I just tried again, turned off everything

Put on the battery then inverter (27.1v)

Connected the load (It ran up to 28.3v??)

Then turned on the solar and its the same not charging but voltage is now down to 26.9v

I turned on my fridge and the voltage is up to 27.4v but still no solar charging

I'm lost now but the Voltage seems to be all over the place.

LITHIUM BATTERY OR NORMAL leadacid battery?..this is a strange behaviour..battery voltage going up when load is applied

Update

Hello chief, gone there yesterday and did few of the things listed here... (Equalizer also changed the battery settings to flood on the inverter) .. Also went with felicity 60a cc sadly that one doesn't accept more than 145v but was still able to use it to charge cause of the poor weather although when the sun intensity increases, it started blinking the warning red light. Anyways that not where am going... what I noticed myself is that, the battery doesn't take more than 10mins before it runs from full charge to completely discharge which is from 25.+v to 21.8v. and also takes abt same mins (10mins) before it get full even to bulk and float level. Let me also call una attention to this, initially when i did the installation, they had two 100ah battery which i connected to it, after abt few days the batteries became so weak and dead. I was like maybe because they've been using those for going to 2yrs maybe that was why, then we got another one.. Brand new ones this time around two tubular batteries 12v 220ah then this issues again which am just so so confused ... I also noticed the battery will start decreasing just like a clock count down.. It doesn't back up at all ones the PV is been cut off.. Same thing the previous two 100ah did.. what is the way forward, what kind of solution can I use to tackle this problem pls.. Will be in the comment section... Thanks all..

their load is killing the batteries...or a dim possibility is that you got substandard batteries.
the wahala with leadacid battery is that it gets irreversibly damaged anytime the voltage goes below 10v, depending on the battery, some might make a better recovery than others...while some will die outright.

u didnt check the SPECIFIC GRAVITY OF THE ELECTROLYTE?...if weak/dilute, it may also cause similar issues..but its a long shot..

your best option is go for lithium battery, a 3.5kwh 24v lithium battery will handle those loads easy peasy....or get 6kwh pack to have more flexibilty

Sapiosexuality:
Try Gennex technologies dot com.

Gennex has high waybill/delivery methods/charges...
Techland is fairly reliable and use pocket friendly options for out of state delivery...

Energymall, is what we need to hear reviews on...
Till we get that, techland is my recommendation

Appliances can go crazy at anytime. I'ld strongly advise never to leave energized equipment running unattended to for long periods. wether connected to earth or heaven.

LOLZ...so cell stations running in remote locations 247 with inverters and automatic kick over gens......is wrong?
adequate protection is key, i hv been out of town for weeks and left my freezer and inverter with solar and grid powered on..zero issues

Ooreofegrace:
Panels are 568w x3
The only heavy load put on the system is the pump.. Which is abt 750 or so watt..
The fridge and freezer is inverter which sometimes stayed btw 114 and 60w..
Tv is below 30w also decoder..
Then bulbs..

Abt the charging parameters, it was left on default. Will hv to get battery charger to check the level..

ok panels check out, WELION inverter, you need to put it on flooded battery setting, not default or choose user and set bulk to 14.7v and float to 13.8v........and activate equalization immediately and set monthly equalization too for 4hrs at 31v.

am assuming the batterys are brand new, so electrolyte SG is correct, just that its not being charged and mixing well cos of the low/wrong voltage. higher/correct charge voltage and the periodic equalization shud sort you out real quick..

your leaving the inverter on default is the likely cause of this issue, and most average installers are guilty of this as well.
also the pump load is a bit high, but if you run it only during the day, with solar panels kicking in juice, you shud be fine

Good day bosses in the house...

Abeg make una help me with solutions to the below problem ..

Did 4.2kw 24v installation with two 220ah tubular batteries abt 2mths ago.

Now the customer sent me a message this morning that for abt one week now the batteries goes off around 2-3am with just DC bulb load (10pices of 5W each).

Load use on the battery.. 1HP pumping machine.. Once in abt 3 and days,running hrs like 1hr max during the day.

Inverter fridge and freezer from 8am to 6pm now reduced to 3pm

And the DC bulb for night useage..

Kindly note that the batteries get alot of charge before the sun goes of.. It always in the float state before it comes down to the normal 50% battery level and still sound for low battery warning even without much load around 3am max..

What can i do to rewake or b boost the batteries pls..?


Thanks all.

U DIDNT MENTION ANYTHING about solar panels?.
max load you shud put on the system without damaging it is 20amps x 24volts wch is about 500watts....that pumping machine, have you checked the actual draw?..same for the freezer.

what of battery charge voltage algorithm...what voltages did u set the inverter to?..abi you just left it on default?
check the SG of the battery electrolyte with a hydrometer and be sure its good

Xanderone:
Submissions have been apt on this. A hybrid inverter in place of felicity standalone (even 7.5kva felicity hybrid inverter is still okay) and a badass 48v LFP pack within your budget is the way to go. The moment I saw 2 tubular batteries in tbe lineup from your installer, I just made up my mind about him

Is an idiot ignorant kazeem installer....
He should go back to fixing bicycles or farming.
That guy shudnt come near an solar installation job

bbally:


The powmr was my initial setup which I have reserved as backup, so it's not in use presently.
My solar panels is 2000w total connected in series.
My battery is lithium 12v/300ah and it was not full when I have noticed this issue and when I switched off and on back, normal charging continues. This only with solar charge and never with NEPA supply.
No shadow cast over the panels though the inclination is off, "na send down the rain roof".
All these started recently, the inverter was purchased in July 2023 but installed in March 2024.

u sure u don't have a partial connection somewhere in the dc cables

EmmanuelCena:



Good morning,

My question is off the solar discussion.

I intend to purchase a 5Kva stabilizer to boost the low voltage supply.

I intend to connect it to my Freezer, and TV

My question is should I go for the conventional big century Stabilizer or a wall mounted stabilizer?
What are the differences in terms of durability and performance?
If there a re better brands I could get also, I'd appreciate.

cc: Jonescosmos

you miss the the point, when buying a stabilizer, your focus shud be on working voltage, not if its wall mount or conventional. 80 to 270 is a good working range, go for such stabilizers, a few stabilizers also claim 45 to 270 volts......this is even better, but know that this model is more fragile and selective about load. a 10kw stabilizer derates to about 3kw if the input voltage is about 150v, so imagine what it would be at 45v

2ndly, the next critical issh in selecting a stabilizer is if its servo or relay....
personally i prefer servo, as it has less moving parts, a relay stabilizer has more parts/relays clicking upandan...so more things likely to go wrong, relay sticking and damaging the stabilizer....though the pros of relay stabilizer is that its simpler..and the average repairer can repair it...unlike the servo wch is a lil bit more complex and may require you sending it back to supplier..aedunamis or prag as the case may be

Xanderone:


Thanks. How long has it been in use by the client?

I need to take my time on this stab issue and critically weigh my choice before taking the plunge. That LG AC mis-purchase is still giving me PTSD.

buy a stabilizer that picks from low voltage --80v, those that pick from 120v perform poorly if your voltage is very low.
ae dunamis is good, if it has issues, u can send it back for repairs under warranty if within 1 yr...or out of pocket payment if more... if your area is prone to erratic over voltage from nepa..try and protect the stabilizer with these digital avr , zeestone sells it

FINAL UPDATE
At long last, I got my battery back yesterday evening. The bms had to be changed and now the battery is currently working as it should. I just hope the issue doesn’t arise again.

wow, since then?...did you pay for the bms replacement yourself?. why did it take this long?

twinskenny:
My seniors I need your help

I did this setup last week, now we are about to add the second battery to it both Bluecarbon 15kw….


Please how do I parallel both? So I will get a single source out of them ?


Thanks a lot…

Use a busbar..
Use equal lengths of cable to connect both battery packs to the busbar.....then do same busbar to inverters

Amador1:

I’ve opened the battery and these are the pictures I took before closing it back. Please if anyone knows where Or who can help get it fixed, please do recommend. I have to revert back to my generator now in this current fuel scarcity wahala.

These are definitely used lithium ion cells, as i surmised earlier..josboy has a thing for them ..
Chk that each of the 14 bms cell leads are tight and firmly attached to the cell pair...though from the resistance values..they appear to be.

I suspect a failing bms...does the bms have an ON bitton?.
U can try power it down/disconnecting the sense and power leads and then powering it back up again..
I dentify the cells reading above 4.2v and attach a car headlight bulb to it..for 10 to 20 mins....that wud drain the energy to acceptable values...allowing the charge and discharge fxn of the bms....then connect the inverter to it and observe.

If the bms has failed..then a simple bms swap shud get u back and running again

ojesymsym:
It says the charge is off, did you try to toggle it back on?

.

Toggle it on to achieve what exactly...one cell has runaway. At 4.8v...the bms shudnt hv allowed that happen.

Best to discharge the pack...not charge

Penuelseun:
from the picture you posted, the bms is only detecting 14 cells instead of 16, did you tamper with the bms settings?

Its likely a 14s li ion pack.
Jos boy was a fan of used li ion /ev cells
The cells hv a diff voltage profile from lifepo4...so uses 14 cells..not 16.

Lifepo4 cell nominal voltage is 3.2v
Li ion cells nominal voltage is 3.7v

easyyoke:

I am looking for 48v sir. Not 12 or 24v. I am also looking for 1500w and below.

what u seek is almost impossible to find as a single unit...48v 1500w, minimum 48v i have seen is 3.2kw
only option is to buy separate 48v charger and satchet inverter 48v

easyyoke:
Can anybody please reccomend a good 48v inverter with capacity less than 1500w output please. My total load is 350w, 400w so all this 3500W, 5000w inverter is just not it for me. Currently using 12v but I want to move to a bigger 5.12kwh battery but if I stay on 12v with this kind of battery size, I will end up spending too much money on wiring as well as charge controller. Lets not even talk of the heat generated from needing 80A to 100A to charge a 400ah 5.12kwh Lifepo4 battery in 5hours if it was 12v compared to just 20A I will need on 48v for the same battery capacity. So anybody with any good recommendation please. 48v inverter. Less than 1500w(1.5kva). Or even 1000w sef. A good and well known brand please.

THERE IS 2KW 12V HYBRID WITH INBUILT 80AMPS CC..CAN ALSO GRID CHARGE AT 60AMPS
24v 3kw hybrid with same specs.
both are high voltage hybrids.
