Topper33:
Guys, Please what are your take on this:

So i have been following this tread for some time and from poplular recommendations to others , I was convinced and then I ordered and received a 3.2kwh battery from a buider on this forum. The delivery was fast, no delays. Although the set did not come with any accessories, no baterries cable etc . This was as stated by the builder. ....(only the battery box in a plastic build with a small bms screen and a button). All as advertised. So no issues there. This setup cost #550k (delivery inclusive). All i got in addition was the waybill receipt

The truth is, my friend who ordered for a 26.5v(100Ah) itel 2.5kwh battery, received theirs yesterday:
To my supprise, the itel battery Bank alone was 2.5 to 3 times heavier than mine, the setup was built in a solid steel housing case, has 3 internet communication ports, and 3 other advanced looking ports. Came with ALL the comm ports cables, also came with two 20 mm solid +/- battery cables , 3 year warrenty card, thick steel wall brackets, metallic wall screws, some addtional bolts and nuts and many more.
And all this cost #481k (including delivery fee).

Now I know why people crave the itel battery pack.

Although I have to say I over expected much for mine, but the person i bought mine from did not give me the kind of attention(as a first time customer as i would have wanted) the response sometimes was quite slow (had to literally push for any information with response coming anything it comes) no step by step on how to do much. I had to ask about value to set for bulk and float etc, Had to push and ask or most times google some stuff on my own. (I am not saying the seller did anything wrong o) but sincerly I dont think I may patronise the person in the future.I like my business partners to be approacheable irrespective of the value or amount involved in the trade......(my choice)

So, the itel on the other had virtually a full hands on manual that explains EVERYTHING you can do, clearly defined warranty card and many more quality of life stuffs you know.....

Although, I for one became a bit skeptical about the build i received (when i recall the itel heavy weight and quality) but everytime i checked the jk bms app, i showed all the cells adds up to 3.2kwh (see image). Even still, my mind still tells me I should have gone with the Itel due to its solid built, wall handing capability, solid customer and aftersales support, the quality of work and support it has.
(I thought going for "3.2kwh" was better than "2.5kwh" so i had to stop my initial itel order for the local build).

Its well sha


Forgive me for my long epistle...Just wanted to air my thoughts man.

Thanks Guys

My take:

Omo that your friend needs to be very very very careful around you. Infact he should run away from you.

LeSaint:
Hello guys, please help me make a choice between Cola 3600 @ 800k, and Haisic 1.5kW 4kWh @ 830k. This system is for my folks' in the villa. A few lights, 42" led tv, 2-door old fridge, and two fans. The fridge is the only priority load. Diversity will apply. Budget is tight.
Already, 4 nos 340W panels are down.

I'm wondering also, are there 2 grades of Cola, as some insist on 850k and above for the same Cola 3600?

Instead get 3kwh must solar generator that will carry fridge, fans, tv lights. 900k which I have. DM me.

Some of these old inverters stay completely silent in normal user except when it hits like 50% of rated capacity and the fans activate.
But these new ajebo hybrid inverters will just have fan constantly on even on low load, and will increase the fan noise with more load hitting it.

These old inverters are just so robust and working for 5-7 years without any single fault

these dead loads that consume a lot of power on standby.

Don't be surprised that there are low frequency inverter that consumes lesser idle current as low as 20w. Make ya findings

The old inverter don't usually multitask and form factor is usually bigger. Cramped in electronics deserve ventilation

Newer hybrid inverters does three functions...charge battery via mains , has a solar charge controller and inverts. All these generate heat, making that fan necessary, but if you hate fan so much, some premium inverters are out there with huge heatsinks and no fans eg Goodwe, Solis, Sigenergy etc

My 4kw Schneider no load draw is 40w.

Growatt 5000ES hybrid has a no load draw of 45w.

Some LF inverters are not that wasteful.

not only high stanby watts, the charging technology of these ancient things are not compatible with LFP batteries.

Icent99:
Good morning everyone, please I'll love to know if there are any effects if i charge my lithium battery with 120V from the grid. The light in my area can be very low.. As low as 120V.i have a 10kwh lithium battery. Is it safe to allow grid voltage of 120V to charge my battery. If not, what are the potential effects. I'll appreciate any useful response

Won't charge unless the inverter/charger accepts 120vac.


It's likely going to give error 10 output power derating depending on which inverter brand

Shenzhen Deriy, Shenzhen Starmax, Shenzhen Basen, Shenzhen Rowen (this one sell more used cells than new)
Your main challenge will be getting a shipper because most of them are not reliable.

Pabodo:
Hello House,
Doez one know
1. Any reliable store to buy cells on Alibaba?

2. Shipping cost (Sea) to Nigeria and how to claim it

Will appreciate advice on this as I am planning to get some cells

AyobamiOluwole:
You are wrong to do your maths that way and you also don’t understand the energy movement.

Let’s be generous to say that the owner uses a 15Watts chargers in his shop:

10 power banks = 15Watts by 10 = 150Watts
15 phones = 15Watts by 15 = 225watts

Total running loads at a time = 375watts per 1 hour.

Meaning that on the system is 375watts an hour. Nothing like 1kwh of power.

The power banks will take 5hours to completely charge while the phones will at most be filled in 2 hours. That 5 hours is enough to get your battery full and still charge those devices if you calculate well.

The duration of how long he runs the 375watts is most importantly based on his solar panels and battery bank. If he has solar panel of 1kwh, don’t forget that the generation of power on an ideal day is about

1k watts by 5hours =5kw

Meaning he has 5kwh per day. While his load is 375watts which will run for about 13hours a day. Meaning that 10 hours is enough for 20 power banks and the remaining 3hours (375watts by 3 hours) is enough for 75 phones.

Do your maths this way, gather enough research to know how many customers you will likely get a day and buy your set up that matches it.

Back to the shop owner and many others like him, they just don’t know the maths too, and they don’t like to ask before they get into it. Chikina.

You didn't factor charging cord/cable speed into the equation

And devices seem to draw more power when charging from empty than when full

Hello. I sent you a message to your email.

Inverter is still in use.
I upgraded to 4.2kwh

Good afternoon guys….so I’m new to this solar stuff and even though I have read many of the pages o still couldn’t find what I want..hopefully someone will help me.

A friend sold me his old 1.2kva luminous eco volt inverter because he’s upgrading…his batteries are dead so I only got the inverter..

I dont like this tubular batteries and one installer said I can’t use lithium battery with this 1.2kva inverter that I will have to get another inverter….

So what do you think?

Can’t I truly use this inverter with lithium battery? I plan to charge more with solar panels though and perhaps once in a while use the grid since the inverter can charge battery….true at the back of the inverter,,no selection for lithium battery….



Please don’t ignore me …I don’t have money for another inverter o.

snap and send the specs on the inverter, we need to see the charging parameters. Since you plan using solar majorly, right? if yes, then get a good charge controller, CC.

Note a good CC is almost equal to a new inverter

Hmmm, so you took action and made a purchase first, before seeking answers to questions / advice?

bassdow:
you know eh, na this kind innocent question cause the one wey people dey argue currently.

See eh, without knowing your budget, it can be difficult and somewhat useLess making recommendations.

price of some brand new inverters would struggle to buy a (smaller) used version of others.

Anytime seeking recommednation, helps quoting your max budget so those responding would know what category to place you in. Make we no go recommend itell or cworth or SmS, or Haisic when we should be doing the likes of SRNE, Victron, etc

Thanks, budget is 400k

You can use it but it's strictly solar for charging your batteries since it has no lithium parameters

you don’t understand…don’t let me use the word purchase cause it’s more like a “guy come pick this thing for recharge card money””….I dodnt really pay for much but since I sent him small thank you change I used the word purchase cause”sold”

okay boss……which means I won’t connect that wire that goes to the grid for charging to the charge socket Abi?

Finally someBody is speaking along the Lines of things I have been saying.

Hopefully, Una no go later begin say similar things about Lithium based batteries because a Lot of them for market na ...

these dead loads that consume a lot of power on standby.

Depends on quality + nothing stops anyOne from having 2 sets of inverters with changeOver to switch them from one solar setUp to another. na wetin I do last year for a client.
2 Inverters BUT a single Solat + chargeController + battery setup hence

That way, when running heavier loads, they switch to highSolar (whose inverter is rated 10kva) otherWise they switch to lowSolar (whose inverter is rated 3kva)

Funny enough, we both both inverters used with batteries from @ those selling in here.

So long you don't plan using generator or NEPA to charge, and youre willing to buy a good enough charge controller + enough solar Panels up to what the charge controller can handle, you shouldn't have issue.

Mind you, the inverter does not have to have selection to be able to use Lithium based batteries so long you not trying to charge via NEPA or Generator

meanWhile, you didn't tell us if it's 12v or 24v inverter.

Thanks, budget is 400k

This budget would get you 4.2kva or 5kva inverter in category of Haisic.
