mayBe @prince4pro2 should tell us their usage patterns. Just like you said, some leave home very early in the morning and come back late at Night. We can't compare their expereince with those who spends more time at home or those with demanding appliances. Or those of us wey get loads that rarely go offLine.

Still would recommend 4pcs minimum to cater for most scenerios especially if there's need to use the setUp reliably while it's recharging.

if money no too dey, e fit do 3pcs but would suggest He / She kukuma waits till the money for 4pcs is complete as by the time you calculate cost of transportations, and installations of the second panel(s), you see you now spending extra. Not mentioning other costs.

He also needs understand He can't easily do Parallel with that inverter

Boss money no dey oo, na cdcare we just the pay small small. the 3 am getting is for the time being . I go still get another 3 making it 6. So that in case of upgrade in battery capacity I won't be immediately needing pannels again. I have already started payment for 3 620w jinko

micxwell:
Same set-up with 4pcs of 615w panels. Battery charges full around 10am.

.
Why am yet to see my battery at 27v charge level. I can see your roof is not send down the rain like mine. I go see how to get at least 3 half cut pannels or if possible 4. Na just money matter .

xzynwa:
Your inverter has 85V minimum solar PV input.

A piece of 620w solar panel ranges from 46v to 50v depending on the brand.

2pieces of such panel may not output the minimum voltage required to start the MPPT charging of the inverter earlier enough, it may during peak sun hours though.

You need a least 3pieces as minimum requirement..

Your inverter can even take up to 6000w of solar power.

With time I will get more pannels. Just looking for something minimum to start up with. I will have to continue sourcing for 3 620w jinko instead of 2

bassdow:
Actually, it tends to depend on specific solar panel as bigger doesn't always automatically mean bigger output.

in your situation, if buying the solar panels brand new OR if buying from someOne who bought them brand new not long, then the 620w is more superior. Also should always be halfCut by default.

So yeah, would go for 2pcs of 620w hallfCut solar panels than even 3pcs of even 450w ones.

As usual, on the flip side, I rather stay with quality non halfCut panel than a halfCut panel that's of very very low quality.

Now you need be sure your inverter is compatible enough for the solar panels.

Inverter spec.

bassdow:
A lot of times, we just understand what we wanna understand.

I have preference for Low wattage solar panels within range of 350w to 450w only when buying USEd ones BUT if buying them BRAND NEW, then the range is 500w to 630w. I wouldn't even attempt buying 400w brand new sef.

na una dey make person type long sometimes.

What I said haven't changed at all.

If USEd, must be between 350w to 450w; max 500w
if Brand NEW, must be between 500w to 630w

Must always be halfCut whether NEW or USEd.

.
Will two 620w jinko pannels perform better than 3 420 non halfcut panels?. I want to get 3 which I Know would be ok for now, but due to fund am looking at just two for now. If 2 can give me up to 900w to 1000w that will be ok for my 2.5kw battery for now

bassdow:
if buying any brand new solar panel, kindly ensure they're at least 620w especially if buying from the Tier 1 brands.

Normally I suggest used solar panels but lately, the prices no longer encouraging when compared to brand new ones.

Another is, Are you sure the solar panels are the issue ?

How did you do your testing to comclude it's not generating up to 700w ? Don't forget charge controllers / hybrid inverters generally only display what they collecting, not what the solar panels are generating.

Have always advocated for halfCut cells BUT that also doesn't mean the non halfCut cells are useLess. Don't be quick to spend money.

tell us your inverter and if it's hybrid, share with us it's sticker, also the external charge controller's sticker if that's what you using. Also type of battery and it's voltage and capacity. Let's not question state of the solar panels yet.

Inverter is itel 4kva hybrid. Battery itel 25.6v. 100ah.

fuckboys:
full cells are an older technology of solar panels. They were used for more of parallel connections.

Get halfcut panels if you're doing series connections.

This solar wahala no the finish

fuckboys:
you should have gotten them all halfcut, even if they are slightly different watts but same halfcut mono.

halfcut panels always have higher voltages and perform very well with high voltage inverters and MPPT CCs.

Am having this challenge, I have 3 420w full cell all connected in series yet I haven't seen 700w before, I thought it was due to LA Batteries I was using then,but now even after installing lithium battery I still haven't hit up to 600w. Now am planning on getting 3 jinko pannels of 590-625 and selling off the full cells. Cuz I bought them as foreign used

Gshems:
Run the earth yourself

How pls

Guys my building no dey earthed not even the popular thunder protector. The installer but breaker/surge protector btw inverter and pv, then Ac output he put breaker . I don't use grid at all and don't intend charging with Generator. Nigga doesn't even know how to communicate the battery with the inverter. After paying the guy I just see the fee as wasted,if u mistakingly touch screw on the inverter e go shock u small. The only thing I think I paid that guy for is just climbing up and connecting my 3 420w Pv in series. Ogas them is there any means I can protect my system against thunder?

HV been trying to post the picture of my new upgrade but Sean and his boys the give me ban. I just tire

Gshems:
Na 24v be your system??

Yes boss.

AyarmBoye:
you. Haven’t dropped your number boss

I did and I chop ban. Will chat u up

bkuranga:
Still available?
I'm looking to buy the SMS.

.
Yes boss contact me

AyarmBoye:
congratulations boss…since you have hybrid now sell me your charge controller now

Powmr pwm 80a and sms mppt 60a, which of them do u need

fuckboys:
how many kva is this?

4kva

Finally here . I don join the hybrid and lithium gang. Installation still on going

dollarnaira:
DON'T TRY IT ON THE MSW

As long as say u don talk am, I no go try oooo. Na same try try put me for the wahala I dey so.

smallsmall:
Give it a try, worst that can happen is that it will shut down due to overload. You Unplug it and reset your System.


Can you please post the link you used in buying it on Konga, here.
And how much was it?
I am considering buying one for one Hostel Student who needs it badly.

.
Item is currently out of stock . Nairalanders una the try ooo lolz

senator282:
Hello guys,who knows if those jinko bifacial panel on cdcare pay small small app are original?
Who have purchased jinko from cdcare app

Hvnt gotten jinko from them but other things. I get from them na direct original,In the previous pages ppl testify buying jinko pannels from them and is pure original. I will equally get from them, just wating for 535watts to be available

Finally arrived from konga. With the free little pot. Sadly am on 12v 2kw sarchet inverter msw for the moment waiting for my already ordered itel 4kva hybrid inverter. Don't know if this guy can work on this inverter pending when my new setup go become functional

Wonderful, could it be what we r thinking

xzynwa:
Which side of Aba are you?

Tonimas express by bicoz

Pls any Installer within Aba? Pls I need a professional installer ooo.

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

.
I did that boss before switching on the Pv breaker. The system I was using b4 trying to upgrade to lithium is a Diy set up. On a normal anything electrical na me the do myself so positive negative no b issue for me. Meanwhile I go replace the inverter with same inverter,while I shop for hybrid, itel 4kwh on my mind, although am also shopping for used hybrid inverter.Godwilling in a month time I suppose done settle

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.

.
The thing be say u can't connect directly to the battery terminal unless unseal the batteries cables close to the terminal and tap from there

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.

Just wanted to experiment sha

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

No I didn't boss. Everything went well untill I tried connecting the communication cable with the battery to the CC. After which I switched on the pv breaker because I been switch am off immediately the inverter that was not even on blow and started displaying 12v likewise the cc. Na so e take happen

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 think this is the main reason y the inverter damaged . So the question now is how do I connect? Or is this battery only for hybrid users?
