cdcare don't sell fake and beside u can confirm the panel serial number on jinko website, but easier way to check the panel efficiency if u are using hybrid inverter just put a load of 1000watt during a very sunny they you see that the yield will be much closer to 535watt may around 400watt plus or u increase the charging current of the inverter

what if a seller duplicates those stickers and uses them on different solar panels ?This check of yours would still proof Positive even when the solar panels ain't.

Anyways, let's be very very careful the way we throw around words. No need even uttering the word "FAKE" when no slightest evidence exists.

Bankyshinani:
I have been using 3 ordinary 450watts panels before and now I just both another 4 450watts which are halfcut

Then no issue. COnitnue using them like that. BUT going forward, let it always be halfCut and if you have to remove any solar panel, let it be the ordinary Ones.

the series number is embedded inside the solar panel by the top conner I mean Inside the glass wen cover the solar cells must tally with wat you will see on jinko website and the panel wattage, )

this is the same 535watt jinko panel 7 pieces, total of 3745watt and am getting 3200watt from it in the afternoon and my load On it was 1900watt, it was still charging my battery and powering my pump at the same time

Pls i need the contact of the place you got the luxsun inverter here in Benin.

Load it up to like what percentage mostly?

HeavenlyBang:
My SRNE 3.3kw has been pretty much rock solid for two years. And I load it up all the time.

Hello Goodday everyone. I have been following this thread closely and I see there are lot of experts here.
I am interested in setting up a solar for my house. I am thinking of a 5kva hybrid inverter and 7.2kwh battery. I was told about cola inverter and lithium battery. Please what do you all think based on experience. I’m been careful not to make a mistake in getting something that may not serve.

Btw it’s a 4bedroom with 1hp AC & sumo pump

oloet:

Air fryer - 1.2kw
Microwave - 1.5kw
Pumping machine - 1.3kw

I use 2/3 plus regular appliances like fridge, no issues. Of course only when sun is out, so as not to stress my battery/battery cables.

Reason you need explicitly point that out else most would rely on sticker. Nigerian drugs does similar where they just put it on the carton

We ned not know how many rooms in your house or flat.

What's more helpful is knowing the loads you intends powering e.g 32-inch LED Tv, 1HP submersible pumping machine, 1HP AirConditioner, 200l Chest freezer, etc

Then you also tell us which of those loads are more likely to be used during the day than at Night.

only then can we begin to have idea of what to suggest.

As for Inverter that eats Cola, would allow those who knows such inverter to comment

hoover420:
Guys, I don’t understand how to read the percentage on this Deriy 3.6kwh.
I downloaded the BMS app used to monitor the battery and percentage but checking the app, it usually doesn’t correspond with what the battery percentage is showing on the battery itself.
Is there a way around it or I should just follow the readings on the app?

Free that voltage screen on the battery.

The app is your source of truth

Okay thank you so much

Good day .. y does everyone seem to say a 12 volt system is not worth it. Inverter nd bayyery wise. Most people say minimum is a 24volt system.

On a 12v system there's less room for upgrades, why?

Because at 100A, your solar charging limit is not more than 1,200w. Which means if you plan to increase your battery size in the future, you'll be stuck at this limit thereby giving you the challenge of charging efficiently. This is why higher capacity 12v batteries are not popular.

At 24v, 100A is about 2400w. This will mostly be your charging limit too for most inverters, that is why above 10kwh batteries aren't popular for 24v systems.

So basically it's mostly about charging efficiently with available sunlight. But if you don't care about future upgrades, trust me, 12v is just perfect for your needs.

Anyone help with experience with Itel Energy inverter performance and durability.
Considering the 4KW 24v Hybrid inverter.

Don't be deceived!
You can do wonders with a 12v set up.
I recently upgraded from 12v to 12v bigger battery. Na sense.

12v since 2011 till date....

There are efficient appliances now with low wattage e.g ac, cooker, submersible etc.

Na who get sense they use inverter.

hello chief, do you still have your 12v inverter, i am interested in buying, I am just starting out with the Lithium planning to get a 100ah or 200ah, just wanted to start small on this journey, or anyone who have a good used inverter, kindly link me up.

in addition to what's said by @Unfaized, at lower Voltage, you need more current hence 24v system is more efficient than 12v system BUT same 24v system is not as efficient as 36v system and same 36v system is not as efficient as 48v system and same 48v system is not as efficient as 96v system, and so on.
So you see, the Higher the voltage system, the more efficient the system is and that also translates to longer battery life.

Now when you alre coming from a 12v system, there's always no room for upGrade to higher systemhence you end up dispossing off the entire thing and starting again from begining which means you spend much more.

I also kinda agree with @dollarnaira BUT it really need be stressed that it doesn't always apply + you really need know what you doing which if you do, wouldn't be asking this question in the first place. There's a reason @dollarnaira said you Must use Sense.

Personally, I run both 12v system and 48v system and guess what, I have reasons why I still run 12v system despite having a much more efficient 48v system. mind you, even my 12v system doesn't even run with inverter HENCE it's even much more efficient than a lot of 12v systems out there.

So except you know what you doing (have sense) like said by @dollarnaira, and your useCase favours such 12v system, you are always better off with something higher.

of course if your load is just a small TV, charging of phpoones, a couple of Lights, and a couple of DC fans, then by all means use 12v system as it's much more cheaper. In fact you could add small fridge / freezer and even small pumping machine if you have properly sized solar panels to help. Even at that, performance wise, and battery health wise, it can never belike a much higher voltage system. AfterAll, Tecno or Gionie or inFinix phone can never be like Samsung or Sony xPeria or LG.


In physics, there's reason we have the formular P=IV and guess what, you can't reduce voltage without increasing current and no matter how much sense you wanna use, the P would always remain constant else something would be wrong someWhere. Let's pretend to also notice the formular V=IR which also plays it's own role.

Mind you, 12v system costs more than 24v system which in turn costs more than 48v system,a nd it continues.

Make we no try blindly change wetin other people foreFathers discovered while our own foreFathers were busy doing religion and inventing parables

Hello Bassdow,

What will your advise be for this type of load profile?

Note that the occasional loads will be used only with other appliances turned off.

Grid supply is very very bad here - almost nonexistent to be candid. So PV charging will be the primary means.

Strict energy management will be in place.

I don't know what everyone have against 12v systems ó. But if you are not running hot plate, ac, microwave 12v can work for you. My 12v carries all appliances in my house. I don't use my microwave with it. But my washing machine, fridge and freezer, TV and fans all work well.

I doubt anyOne is saying 12v system wouldn't work. What we saying is, it can't work as Good as 24v or 48v system

Dabss:
loooool this is so spot on. I have a similar setup
60A Felicity CC, 4 PCs of 525w bifacial panels and I can't get beyond 1200w/h. At some point I was thinking my panels were fake. 😀

Is your inverter setup 12v or 24v system?

Baba do you know that there are many appliances out there with great lower wattage?

Just yesterday I ran 2 freezers with a sumo on it?
It was as if I did nothing. Sumo ran for about 18mins. There are better inverters for this purpose.

Now, there are inverter ac (400w or less ) at moderate temperature and up there induction cooker with 300w or so. So what are we not saying?

Wow!
1. What's the size of the BMS on your battery
2. What's the HP of the sumo you used on it and
3. What's the capacity of your inverter and type of inverter?
Thanks.

How long have you been using this your induction cooker and can I see the free pot it came with?
