Please can anyone give me review on affripower 2.5 kva hybrid , i used it with 3.5kva generator but it does not charge and we hardly have public utility.

try to reduce your charging current. Check ur present charging current

temi4fash:
Can you expanciate on this?

from your calculations, the CC cannot be used for the 2 arrays right

this is y i brought this to the elders in d house. I b tital novice. I can as well fo aheaa n use it cos i kno max i can see is 6A which will not hurn my inv as max it can take is 15A

You get time to they explain o.
There are fake and original humans.
Those who buy from you will understand.

valto battery de handle loads wella. One de site de work him arse out

casualobserver:
You clearly did not understand what I said. What I said is that I prefer a hybrid so it powers the load 1st and then charges the batteries with the excess and only draws from the battery when the solar power is less than the load or at night which is what you have described above. What I said is that if I decide to use a SCC to charge the batteries in order to allow for Temperature compensation either in addition to a hybrid or in conjunction with an inverter charger, you are drawing power directly from the batteries or wasting solar power.

It’s not a very efficient way of doing things because it means having to dedicate a set of solar panels for daytime consumption via the hybrid and another set for the SCC to ensure temperature compensated charge of the batteries. In addition you can’t totally stop charging by the hybrid so even if you limit the current to the minimum it will still send a higher than appropriate charge voltage to the battery. One might as well stump up the money for a Deye with BTS or get lithium. In any event should their be a need to charge the batteries via the hybrid either on cloudy days or at night we are still back to the original problem that all these hybrids on the market Growatt, axpert, felicity etc do not do temperature compensated lead acid charging and will degrade batteries in the long (maybe even short) run.

Abeg nor mind me jare. I wanted to edit my post but mtn n nairaland refused to allow me breath. I understood ur post clearly. Hybrid is gud wen u have enough pv in various weather intensity to cover ur loads if not it ends up substituting d renain current with ur battery. GOD B WITH U if u re using lead acid. They wont last becos de will receive partial charging cos of low pv input

casualobserver:
This is the problem I have with tubular batteries. The problem is that when charging a flooded lead acid battery, you are supposed to temperature compensate. For instance you are supposed to reduce the charging voltage by .005v for every cell for every 1 degree increase in temperature above 25degrees. If you have a 48v system that is 4 batteries x 6 cells per battery I.e .005 x 4 x 6 or .12v per degree above 25.

Tubular batteries should not be indoors but even indoors the temperature could easily be 30c. If they are placed outside the temperature could easily be 39c and often 35c. At 35 degrees you are sending a charge voltage to your batteries that is 1.2 v above what it should be. That’s what you call overcharging and this degrades and kills lead batteries. That is what leads to the bubbling sound you are hearing. You are effectively equalizing your batteries all the time….and giving off gases. Bubbling should only happen during equalization. Equalization should only be done once a month a or once every 3 months.

The problem is that most of the hybrid inverters on the market do not have BTS for temperature compensation. The only one I have seen is Deye and we all know deyes are expensive. The only way to properly charge your lead batteries is to use MPPT charge controllers as they tend to come with battery temperature sensors. The problem with charge controllers is that you are constantly pulling power from the batteries not directly from the panels with a hybrid. I would rather power directly from the panels and draw from batteries only when solar power is not enough or at night than constantly drawing power from and working the battery with a charge controller.

This is the dilemma I am trying to solve myself before I pull the trigger. If I go lithium I don’t want to get any of these cheap lithium batteries like Felicity (1st hand reviews/ opinions are hard to find and the few about are spotty at best) and I don’t want to spend 1.5-6m on 8 tubular batteries that may not last because they are constantly being overcharged.

I t will be interesting to hear from the experts how they account for temperature compensation when they 8nstall tubular batteries.

i beg to disagree on the part of drawing current from batteries. When ur pv surpasses ur current load it would power ur serup without touching ur batteries if in excess ur batteries will charge

richmond500:
The essence of these policies is to kill importation business and make Nigeria a production country.
Your business is not the only business that is dying, many business that depends on dollar has closed down and more will close too.

Time is coming when Naira will hit 5000 to a dollar. When this happens, foreign products will be difficult to purchase and we will have no choice but to buy made in Nigeria goods cos even a pair of foreign pants will be so expensive that only politicians can afford it while the rest of us will wear plantain leaves.

It's so annoying that the average secondary school student knows the dollar to naira exchange rate, that shows how we depend so much on the dollar and killing our own naira.
Until we patronize our own companies, we can't grow the economy, this painful stage is called the transition stage from foreign to local, the govt is not the problem but the time it takes Nigerians to accept the Nigerian goods will determine how long the pain will last.

In the next five years, we will fully accept our own economy and in the next ten years, we will have an economy that will beat France and Germany cos we have the market already.

Wat are u even saying. Where are the companies dat wants to do local production. Where are the raw materials. No ekectricity. Abeg nor annoy me this morning. Y is dollar to yuan not affecting the US economy. De judt imported how many SUVs. Wat stips dem from patronizing innoson vehicles or give him support to produce quality standards if de are afraid its not up to.

bassdow:
Would appreciate if you tell us how you arrived at this. that way, next time, he/She would have little reason asking such question.

As for me, so long chargeController max rating exceeds total Voc of panel, I just series everything.
That has added advantage of cooler cables

Make i chuk mouth 4 dis installation . Panels are 380w* 6 exulted eagle with Voc 67v and Isc 7a. Load is abt 900w to 1kw contnious. Batteries na lithium 24v 173ah. We plan to add extra 6.

With all d six panels battery turns out @ predefined cut off of 24.5v. At abt 5 to 6pm in the evening.

The problem now is mppt input current max is 15A. Going by 7*2*1.25(safety factor). Dat is 17.5A. Me n u kno say we nor go see 7A.

Me i was suggesting 6s2p. Another suggestion was 2 use a seperate cc n parallel d incoming six panels 2 charge up the battery.Was ur take oga

Justice629:
@bassdow
I gbadu your inputs here well well but as I no be keyboard warrior I say make I maintain for corner the look many of them do called solar pros here.
Little piece of advice- when you ready to go lithium no make mistake of buying from naija vendors because must times na worst grade cells them dey buy from China, my own experience still the pepper me for body now.

na wa. If d vendor de offline or online postcam make everybody see.

Anyone familiar with Air-conditioners calculations on inverters for both inverter n non-inverter types.

ameh99:
12v 50AH lithium battery packs now in stock

call/whatsapp: 09068448005

location: Abuja

u de rush de post .. u nor fit com defend urself on top cells wen u sell.. the funny tun abt lots like u is dat u feel u wont be caught.

I wonder wat is in those battery packs.

Make i even assume say na me de lie 4 d gp n u re d truth master.

Does dose cells look like a 6 month old cell? As a professor in battery chemistry. How do u explain such battery configuratuons u just made up there? How do u explain to this group thst u built a battery pack with mismatched cells ameh99. Dat ur bsttery pack arrived its destination n refused to turn on despite having chsrging voltage across d terminals. Thst i had to start buying tools just to retighten terminals just becos d cells were moving from one end of the casing to the other. The flexible wire u used as busbars cut off from the terminals because of the movement of d cells. Abi u don forget where u still ask me 2 go n buy spanner n insulate dem just to tighten the nuts on the terminals.

Lastly be bold enough to tell this group how mych you sold the so called 24v 200ah pack to me.

ameh99:
shut up for ones I beg you
is your prismatic cells li-on or Lfp?

you said I used li-ion bms on lifepo4..
tell say you wan learn work n...I'm still open

Oga y u de lie na? Apart from lfp 24v 200ah cells, did u not do another smaller pack 4 me? It was supposed to be 3 packs. What bms did u use in the smaller packs

ameh99:
can you post the picture of the claimed Li-ion bms please


I never wanted to explain anything here because you refuse to be reasonable
you bought battery pack from me and complained after 6months of use and I ask you to return it not ones not twice, did I not ask you?
but you said I should come down to Warri to get it .
who does that?
I should travel from Abuja to Warri to retrieve battery.
there and then I knew you were not reasonable.
when you started sending threats messages and insults I had to block you because you were really childish
i was ready to replace your pack but with the threat insult on daily bases.
I even gave you my address but I realized you are really childish
for calling the 8s bms Li-ion bms then your even dumer than I thought..

and you have been begging to teach you all those years, remember?

did u hear urself? 6 months you said? Well its am open forum so you can lie.. u did 2 pack of mtn lumunious cells. How long did it take u 2 refund d money for d last pack dat was with u. The laptop pack you gave to me. Whsy kind of chsrger did u ask to me to buy for it? A normal laptop chsrger dat does notin but chsrge batteries to infinity.
Even the mtn luminous pack you sent you asked to go n buy a toshiba laptop charger 15 abi 19v for dat matter 2 charge d cells. I still have d adapters.

Yes i was begging u to teach me but tank God u didnt becos i wud have brought in fire services in the near future. Even d job i almost gave to you , thank God the client choose another alternative. U wud have ruined my relationship n business with the client .

u used a bms meant for 18650 l-ion cells 3.7V to couple a lifepo4 pack

u sold damaged crap overused 80ah cells and matched it with crap 105ah cells to couple battery for me.

mctfopt:
I always say that if you run a dubious business, you can only make a one time sale. That's it. No return buying, no referral, brutally honest bad reviews, etc

Not worth it if you ask me.

Lion BMS will allow each lifepo4 cell to charge to 4.2v, that's a death sentence

FYI these cells you uploaded looked older than some cells I bought in 2019

e did use a daly bms on the pack. Na one other small pack e put d li-ion bms.

swagifted:
if na continous should i be worried sir?

yes sir.

dollar4naira.. thank you jor...nairaland and this cloudfare nor gree allow me upload picture.

oya come defend your self ameh99

swagifted:
is there anyone here that have used firman line or hybrid or non hybrid inverters?

if u de use hybrid, abeg buy panels many welll ooo.. there is a reason for the high voltage input.

btw sef ur load na continous usage abi na charge now and use later

ameh99:
you are so childish and I won't respond to you
come out one on one and talk but you just hide behind your keyboard and type rubbish...
you will only kill yourself of hate and stupidity

i know u ve no shame. Wetin i de hate u for? For olodo wen u b? Person wen de couple lifepo4 pack with li-ion bms abi u go deny dat one 2 for the 24v mtn luminous cells wen u couple?. These are the cells u sold to me in d 24v 200ah pack. Am very sure you recognized dem . Cells of different Ah capacity dat u mismatched to give me 200AH. In less than 3 months cells became swollen. Wen i took dem apart, u need to see all terminals with their thread worn out. . My load nor even reach 100w yet small rain go fall. I go de fear not to sleep 4 darkness even witih 300w*4 panels.The whole pack was dead on arrival. Na manipulation dat stuff take on. This one nor b matter of waking up bms. I knew how fustrated i became after spending so much on a pack i cant use.. i had to look 4 alternatives.. To even say dat i was ripped off is an understatement, this nigga showed me love n F****Ked my a***s. ... when i compared the price i bought the pack with that of others in recent times i go just shake my head. If na family problem u add put for gud.. e even pass nigerian problem.. Make i ask u something, the money never finish?

But the "N" de okay for you , how many you need make I go bring am kom?

lol.. typical nigerian seller. Dem nor de shade d original

Oga shopnig24 nor fall ur hand òo

kristien4:
its worth mentioning that the battery that is out of sync, i used it separately for 3days with 12v inverter(light usage), before connecting it with the remaing 3 for a 48v series.... could that be the reason. I bought all brand new from an accredited dealer...

did u check if its d same voltage with d rest before connecting it back?

bassdow:
is it your ignoreRance ?

u n dis ur bad mouth ehh

dollarnaira:
I need them at good price though.

check dm

dollarnaira:
Are those Samsung cells still available?
I doubt!

24v 100A is not a small pack.

The Samsung cell is 2.6A not small.

dem yakpa

I don't know about reliability o. My SSD failed up on me in the middle of a project. In short, the HP SMART feature started reading error with it and made it a real only. Anything you save will not be there on the next booting. The luck I had was that I had cloned a HDD because I wanted the much tauted speed of the SSD. I had to fall back to that SSD. In all my years of using computers, I am not sure any HDD has failed on me while inside a PC. They may fail as external but not inside a PC.

Now I want a hard disk and I am still thinking if I should risk it because I do not know if it was a one-off or it is a prevalent situation.

premium ssds are a little bit pricey. Wetin full market now na shinko. U go see 3yrs warranty on top label. Seller go say e nor gurantee dat one.

dollarnaira:

How many pieces u get?

no one 4 now sef. i b say if i buy some items i go pick up some cells join to arrive by jan or dec sunce we still de oct. But this safety tin ehhh unto li ion e get as d tin take de. The pcb boards de make money de increase. Dollar is not smiling with anyone. DIY route com de won b like factory assembled pack. Na small 24v 100ah i feel like do sef. I b see some clearance sales 4 samsung cells dem cheap but mah small
