Oga valto, I no dy happy with u o. When I be wan buy early this year. u say na only the 1.4m own dy.
Say u never dy construct smaller packages.
When I ready sha, na better discount u go give me.

emmaniche:
I go like know him name o. A DIY pack i got. Just make me loose hope. The guy made use of old cells after I explained to him that I need new materials.
Long and short. I just dy manage am, even though its usage is not convincing. Wish I cud praise lithium packs the way people are accorlading it on this platform.

To crown it all, a lot of my folks dy seek referrals but fear no gree me cause my reputation go just receive insult. If u build be sincere in ur doings.

TechGeek777:
Can you please mention the guy's name?

Penuelseun:
it should work with 3s2p, what is the VOC of your panel?

That I can't confirm, but each sud be about 40voc!

Penuelseun:
2s2p is your best shot

Bosss. Weldone.
My installer did a 2s3p installation on my 24v battery 150max V CC
I called him that I'd prefer a 3s2p. He said that my inverter and cc can't take such config. Please advice me Sir.
Thanks.

If u check properly, people who inflate prices of used items are 2nd or 3rd hand relative to the item they have for sale.
They mark up the cost at which the owner wants to sell with their own interests.
3rd or 4th hand guys, create ur own group and leave this thread.
Thanks.

icjunior:
You should see it from your cc if you're using one.
That's mine last weekend 938.1w

Boss how did u connect ur panels. Parallel or series.
How many panels do u have. Cause this ur yield be like u get 50 panels o.

emmaniche:
6x300w mono. 31v each panel.
See mppt pix.

@6x300w
Parallel connection will give me
31v 48amps.
2s3p will give me
62v 24amps
3s2p will give
93v 16amps

Am a newbie, please which option is more favorable.
Pardon any error u might notice. Thanks bosses.

Drgreatone:
What's ur panel specifications? Voc and Vmp? Imp and Isc? What's ur mppt max pv input and volt?

6x300w mono. 31v each panel.
See mppt pix.

Drgreatone:
That's what's causing ur low yield. You are using an Mppt not a pwm so why parallel all? Who did ur installation for u? For the powmr which i think u are using, max mppt voltage for 24v system is 105v so for me using 4 300w panels with pmax of 43v, I did 2 strings of 2 panels in series and then parallel both. U need a higher voltage input to enjoy ur mppt.

K. Actually have a 60A zinox mppt.
U mean it sud be 2x31v in series and parallel the 3 sets.
Correct?

Drgreatone:
How many volt system? How many watts from ur panel? I have a 24v system with 1200watts of panel connected 2s2p and i get btw 700 and 900 watts using a 60amp mppt.

Mine is all parallel. 24v. What part of Nigeria are u?

Drgreatone:
Ur solar harvest looks poor, 600watts from 1800w panels seems low. Instead of adding panels, u sud find the fault first. How were the panels connected? Is it even facing the right direction? Is it exceeding the max pv volt of ur charge controller? U are using bigger batteries now which wud require more charging time, than the previous 200amp battery, depending on ow much u discharge it.

I think its a region or amount of sunshine.
Have similar setup and the max I've gotten this period is 22amps.
Just myv2 cents.

Dam5reey:
Sure, its enough to give you 5KWH on average.

Get about 21amps. Though the weather no too makes sha. Sun just show up today.

Guys. Is 6x300w mono panels enough to charge a 2.5kw lithium battery?
Thanks.

odimbannamdi:
Jesus!!! That's expensive!

Thanks o. Got my cc delivered.

Gshems:
Please how much did you get this

Someone is offering it for 140k.

My bosses, is it advisable to buy this kind of cc.
See pix.

We up

Good Day my bosses.
What is the best series or parallel combination for my pv.
I have 2 ploy 300w panels.
2 mono 280w panels.
1 300w mono panel.
Will be adding 4 300w mono panels in a couple of days.
Is the 3s3p or all parallel combo best for me.
Thanks.

HUU.

Drgreatone:
Thought the maximum panels for 24v is 1440watts?

Boss. I have 1500w pv already. Planning on adding 900w, is it ok I add it to my 60amps mppt cc?

jboixxx:
[color=#0000ff]Use v. cards or the ways you heard. [/color]

Thats strong from u o.
Never reach fight na

jboixxx:
[color=#0000ff]Just like Jumia but you'll need dollar card for payments. That's the only thing. Get a dollar virtual card or get a prepaid $ cards from any of the deposit banks.

That's all. [/color]

I heard there are other ways asides prepaid or postpaid v cards!

I need guidance on how to successfully pay for items on alixpress. Thanks.

Loving this thread.
Whats the best way to start buying items on aliexpress?
Thanks bosses.

Abeg no need for insults.
Let's accept right and wrong and move on.
All parties should calm down.

bassdow:
you can't, or not adviceAble to mix 450w solar panels with 300w solar panels.
In fact, when using more than 1 solar pael, ensure they're at least, of same Capacity (Current, Wattage, etc) and type e.g MONO, or POLY.

Also, didn't ask for Max-Input Current or Voltage of a single solar panel but for the entire solar panels.

Let's assume the Max input Current of one of your soolar Panels is 20A, and you currently have 5 panels, and intends adding more 5 panels, bring the total solar panels to 5+5=10 solar panels, then you would do 20A * 10 = 200A. Of course that depends on the configuration you intends using because that 200A cound end up being 100A also

pardon my noobieness.
i have 1500w in total.
generates about 400 to 500w on my cc.
get between 12 to 18ahms charging.

Hope thats enough to advice me effectively?

bassdow:
you failed to state if your charge controller is PWM or MPPT. That really matters.

Also why mixing solar panels of different types. Either focus on MONO or POLY.

Would suggest that since you intends adding more solar panels, focus on MONO and not mix up again so that the mixture no go too plenty again.
Would have suggesting removing the POLY entirely but I don't know how healthy your pocket is.

As for if your charge controller would work, just add up the enitire Max input current of your solar panels and if it's above 60A, though most times, the charge controller would handle things accordingly.

should in case the Max input current of the solar panels exceeds 60A, you could change configuration of the solar panels to combination of Series & Parallel to reduce the output current from the solar panels. Just be sure your chargeController is designed for such voltage.

thanks for being very blunt.
boss i currently have an Ipower 60 amps zinux MPPT.
max solar voltage 145Vdc
max solar current 60amps
max current charge 60amps
i plan on adding 4 to 5 more panels.
Ive been advised to get another CC if am doing 450w panels, if i wont maintain 300w panels that i currently have.
