Hello guys,who knows if those jinko bifacial panel on cdcare pay small small app are original?
Who have purchased jinko from cdcare app

xzynwa:
Which side of Aba are you?

bassdow:
Still believe if you had connected the battery first to the charge controller, before the solar panels, the battery would have dropped down the voltage coming from the solar panels to the battery's nominal voltage. We not there with you BUT if you had connected the Solar panels first, or you connected the battery first BUT did not turn it ON (a lot of these Lithium batteries do have a power switch), then it's high voltage from the solar panels that damaged your inverter.

You alone knows which you actually did BUT if it was properly done, there shouldn't be any issue

cutefy:
That should be the battery terminal.

1. First look for a way to connect the CC with appropriate DC cable size (Positive to positive, Negative to Negative).

2. Then connect the inverter to the battery terminal P to P, N to N.

Or you can do number 1. Then turn on the CC and configure it to match your battery voltage before you move on to number 2.

You should be fine.

Unfaized:
If I may ask, why did you want to communicate your battery though?

In my opinion I think inverter to battery communication is one very needless feature, especially for small systems. In complex systems involving multiple batteries/inverters yes its understandable.

If you think otherwise please educate us.

zenith4biz:
It seems you mistake positive for negative in the first attempt

cutefy:
I just saw your post. Sorry this is coming late.

There's one thing about stand-alone inverters, they need to be connected directly to the battery terminal.

The charge controller should also be connected separately and directly to the battery terminals, (except you're using hybrid inverter where just one wire to the battery serves as both charge input and discharge output).

When you do this, the CC will detect the potential difference between the terminals of the battery and prepare for charging.

The inverter does not have such potential difference across it's terminals.

Now you've learnt your lesson, don't repeat same mistake.

I don go mess up I tried connecting the communication cable to my Cc . As i on pv breaker na so my inverter that was off blow and now reads 12v same with the cc. If u connect 24v battery to the cc, e go the blink error but if u connect 12v the cc go start to the charge normal. Pls guys watin be my hope.

though haven't used this product for any client BUT it looks like it should autoSelect battery voltage.

Are you sure you connected the battery cable to the right terminal and right polarity ? Certain mistakes are easy to make aTimes

bassdow:
what communication cable ?

Doubt that charge controller is meant to communicate anyThing. Na to just connect battery and solar panels.

try connecting again, they show us image of the error you getting and terminals.

AyarmBoye:
yea a good controller should

AyarmBoye:
you need to set the CC to 24v before you connect the battery to it since the battery is 24v….

Ezimuoh:
Your charge controller is supposed to have settings for system voltage, I guess its currently set at 12V, you need to change it to 24v. Share a picture of the cc

bassdow:
This also would work. Either way, just ensure to keep cables as SHORT as possible

bassdow:
Wait Ooo, You guys still doing your every Monday Holiday over there ? Public servants dey enjoy Ooo

Rather than TRYing to say it, attach clear pictures.

But without even waiting for pictures, would suggest you get someone who's comfortable with things like this or follow our lead.

First you got at least 2 Options:

OPTION 1:
Since the battery hehad doesn't use Bolt and Nut, kukuma connect the inverter's cables to the charge controller terminals. Just twist them together firstly, before inserting innto the terminal blocks hole before TIGHTening.

OPTION 2:
Buy long Bolt and Nut + washer. Ensure the bolts are at least 2-inches long. Also every bolt and Nut should have 2 washers.

Now connect the first end of the cable to the inverter. For the other end, attach a screw onto it and ensure it still got enough portion left.

Now take a section of the battery's cable and peel off the rubber protector a little, you see the flexible wires inside, divide them into 2 parts (still don't cut), just divide them, then pass the bolt (alreadying containing the waire coming from inverter) at the center, add washer and tightening with NUT.

After doing that, use enough Black tape to ensure everything is properly covered.

Would have done a SKETCH but just too lazy.

The battery head of that itel battery is not bolt and screw, it is more of socket and plug. That is what he’s try to say

AyarmBoye:
Guys please is this panel up to 300w before I go buy 4 pieces….im skeptical about it..The sticker shows 300w

First get home and get settled. No worry, we understand.

Then it's always RED (+ve) of inverter goes to POSITIVE (+ve) of battery. Then BLACK (-ve) of inverter goes to NEGATIVE (-ve) of battery.

Since you using external Charge controller, the +ve of the charge controller also goes to the POSITIVE (+ve) of the battery, while the -ve of the charge controller also goes to NEGATIVE (-ve) of the battery.

Hopefully said battery came with battery cables else you would need purchase appropriate cables. Don't use just any cable Ooo.

Hopefully your external charge controller is the type that autoSelects battery voltage. Most are, BUT still it's worth mentioning as there are those that ain't e.g the first time I connected my FangPuSun controller, glad I was quick to hear the sound of boiling inside the dryCell battery and my curiousity quickly kicked in to realize it doesn't autoSelect.

micxwell:
It's not heavy. Go and try 16kwh batteries, you'll understand the meaning of "damn"

You mean connect the sachet inverter to the battery or what ?

prince4pro2:
My itel 2.5khw just arrived . Guys hope I can use without charging or do I need to wait and charge fist? Cuz the thing just enter this evening. Is dam heavy!

AyarmBoye:
please charge to full first o….how many panels do you have to charge this?

chadbasin:
Please is Konga the best place to buy it from, and is Dayo the best brand?
Thanks.
