earthrealm:


you have a point,
however i have seen several dumb yphako inverters/charge controllers.
foolish inverters without editable charge voltage settings and proper smart battery type switch useless or non existent LVD & HVD settings......... in this day and age, how can a company make such products?. luminous and mecury are also fond of this poor design philosophy issh

OK, I want a hybrid inverter, which product would you advise I go for?
i also saw a yohako charge controller, same issue-- it just has low and high for battery type, ,
until they wake up and start producing smart user friendly products...i will continue rating them low..

Any company still making products with such poor designs is not serious...
Luminous, mecury, yohako, etc are on this table

OK, thanks, which product would you advise I go for? I want an inverter that can take my 138l fridge and my nexus 5.5kg washing machine. Was thinking of going for a 2.5kva hybrid inverter

The reason why I was considering mercury is because they are the only ones I have seen offering installmental payment. I don't have the money to pay for everything at once

earthrealm:


very very funny.
what manner of logic/reasoning is this?

Observe Nigerian market.
I will love it if any one can point out an Indian lithium battery and inverter.

Besides, the aim was to control waste dumping

Does anyone know where I can get this kind of charger in Nigeria? 3.65v 5a

i really really dont understand your logic.....
innovation is the lifeblood of the world
as per inverter&batteries india is like nokia, .... they refused to evolve and switch to android, but choose to stick to the old symbian OS......and the world left them behind...

indian inverter and battery makers are still stuck in the past, they have refused to evolve and innovate...still churning out rubbish in 2024!!!.

take luminous for instance--- the produce flooded batterys that they themselves know requires 14.7volt bulk and 13.8volt float and periodic/monthly desulphation at 15.5volt for 4hrs, yet they design/produce inverters that output only 14.4volt bulk and 13.5volt float, has no periodic equalization function whatsoever....they also use a useless fixed LVD of 10.5v which at that voltage the battery is irreversibly damaged as well
whats really is their aim for this bad/destructive design philosophy??, which they have stubbornly refused to change/upgrade for more than 15yrs now, ....na only them sabi

..i call this stone age design or design to fail. same people u are prasing & defending

anybody still buying any luminous inverter and their likes in this day and age is largely ignorant or not well informed

The aim is to collect your money every 9 months. They will say you abused the battery, hence it didn't last.

It's a deliberate act!

Omo Na really finishing

At least one point Is clear, there is no hybrid inverter with lithium profile coming from India.

Am speaking in respect to Nigerian market.

My point is this countries are operating on certain government regulations(am very sure why India is not producing lithium stuffs, it's due to environmental hazard).

You see that flooded batteries, luminous are not the only ones guilty many big name are on that table.

For the LVD Na true , then no go sell market if they do it at 11v😆, besides users will complain that the battery goes off too early.

I have met a clients that asked me to adjust the low battery. (Some inverters has option for you to choose the LVD)

The best battery for 10.5 lvd is lithium ion.
No inverter that i know of can drain it to 9v (3v per cell) despite the fact that spec sheet says 2.75v. However, one souer like data drained it to 9.45v.

UR MATH IS WRONG.........
though lithium can handle draining to 10.5v ie 2.65v per cell, it may unbalance the pack, if you dont hv a good balancer.

How boss

I've about 15 pcs of 12v inverters that the lvd has been set to 10.5v and that was very unfortunate.
I will only make sure that the cells are well top balanced and set to 2.5v lvd. One major advantage is that the 12v lithium battery hardly get out of balance when compared with 24v and 48v pack.
Though it's wrong to allow the bms to handle the lvd instead of the inverter, but what are the consequences of allowing the bms to do that job?

Not true.
I eat and dine with lithium ion
You divided by 4 instead of 3.
So it is 3.5v per cell super safe.

Reason for an active balancer esp for 24v.
As for 12v na extremely safe configuration.

ok yours is lithium ion - nominal voltage 3.7v

I deal mainly with lithium phosphate - lifepo4---nominal voltage 3.2v

that's what caused the confusion. ur maths is correct for lithium ion, but not correct for LIFEPO4

No need draining to 2.5v for lifepo4. there is not much capacity below 3volts. frm my battery capacity tester..its just about 10% capacity between 3volts and 2.5volts. i set my lvd to 3v, peace of mind. for new well balanced cells, no need for balancers sef

No comment about the rest but Sorotec: a big NO. Gennex will outlast the Sorotec by far under the same condition

earthrealm:


yohako isnt among the good inverters...also mecury.

why not get growatt or felicity hybrids...or even powmr or sorotec. those hv a decent track record

adibo:
Thanks for your response. I spoke about Yohako because my brother is an inverter installer. He told me that he used Yohako for some years that it is a good product. I dont really know much about it. I assumed that Mercury inverters are good because of the brand name. Ok, I will look at the ones you mentioned

I got a Yohako a few months back on an emergency basis. doing fine so far. I however have an habit of not stressing my inverters pass 50% of rated capacity on daily usage. its still early days yet to comment on the components surviving wear and tear

I got a notice of price increase about a week ago. Maybe that contributed to what you encountered,

I disagree with your submission in terms of lfp battery quality in USA.
Most of us here are members of other forums dominated by foreigners including USA residents.
Maybe I would drop some lfp battery USA warehouses including reviews from various companies (Docan, Luyuan etc) and perhaps the issue some people are facing there regarding the genuineness of the products in question.
Someone shipped 280ah cells last year October from New Jersey with no signs of use and the manufacturer date of March 2023. He was happy that he has gotten quality cells but when he dropped the pictures of the cells in the forum for confirmation, Steve_S and others told him after the analysis that if he removes the black cover from the top of the cells, they're certain it would show signs of sanding and re-lasering. Of course the cells were not legit.
Most of us are facing the same issue from these dubious vendors. The latest Eve grade A 280ah version comes with double screw terminals and test out at 292-298ah and will deliver the full 280ah working voltage as intended.
We should take note of the terminals being used on the cells. As usual, grade B cells will have welded studs instead of dual hole mountings.
Unfortunately, some vendors are still flogging cells with tapped holes.
Submission: A lot of people from USA are buying fake cells just as Nigerians do.....
If you don't know, you don't know.

What reliable seller will you recommend in Nigeria? In the US for example, signaturesolar is a go to seller of good solar systems, there are other good sellers I can think of. Who can you say is that way in Nigeria, where I can buy these things with confidence? It's been too hard to figure this out.

It's either overpriced, or fake. The point I was trying to make is that it's easier to get good solar panels, batteries and inverter here in the US. I never said there was no fake or shady sellers in the US. In fact, solar installers are known for their shady business practices.

sites like batteryhookup.com and 18650batterystore seems to have the double holes on thier eve 280ah cell. D price now nor b here judging our current dollar rating

I initially thought my YOHAKO inverter was dumb too until i experimented a bit with it. By pressing down on the ESC and ENTER button together for about 3 seconds, you will enter an interface requesting for password. Generic password is 12345. You will then enter advance settings where you can modify quite a lot of settings including LVD etc

Interestingly, another Chinko inverter I saw somewhere ( i think Kartel?) has exactly the same MO

This one testimony are coming from yohako users .

Good day,

I will strongly advise not getting your equipment from the US based on
* warranty claims
* Aftersales support and other factors too relating with sub-region
* Voltage output differences.
* Logistics (Shipping cost)

Plus, quality is kind of relative to how much you can spend on a robust product. There are products available locally found in the EU and US markets known worldwide for their strong performance. For the lithium batteries, good brands here give their best too.

To answer your question
You need to have a solar consultant who will go on to recommend products that you can research and make an educated and informed decision on.

I hope this helps.

Yes! you can.

Since this move is likely to be observed manually, try to note or track the movement of the sun through the day and check if the better part of the sun moves over the proposed solar installation.

Buy Deye lithium battery from authorized dealer in Lagos. I've been reading positive review about that products. Their inverter and lithium battery are good.
I can't think of any pasted sticker or false nameplate on their products for now though I'm still afraid of Alaba boys.
Buying it from the direct dealer will give you peace of mind.

Yes! it is working fine.

Typically, solar panels will produce 85-70% at peak of their working conditions locally here.

You were doing 78% of your capacity, i'd say that's a good one.

Congrats though! Enjoy !!

kristien4:
Thanks bro. The thing is i upgraded my panels yesterday.. 6pieces 580w solar panel. 2 panels connected in series into 3 places. Thats 2_2_2 in series, all paralled together. I just put it under heavy load. My growatt charge controller displayed 2730watts pv input.. 18amps pv and 90v pv. Its a 48v inverter... 4 pieces 12v LA battery is series..
Each panel 51v
13amps
580w. Just wanted to be sure its working fine. Under the heavy load, pv input amps stays at 18amps, While batt says 43amps. Was thinking the pv amps would get to 30amps and above or something. I should just believe everything is fine since I'm getting 2730watts from 3480w panel on heavy load.
