Sometimes there is waste in the midst of need

You have them for sale?

swagifted:
yes

Good one Pls, send me your WhatsApp number on [email protected]. Thanks, Sir

HeavenlyBang:


Doubt you'll see. Even Longi 350w s are 11A. Same as Jinko 440W.

Dang. I'm trying to see how I can wiggle my way out of Growatt's ES5000 22A maximum input current.

Now available

Avr/current limiter with kwh(energy) display.

Know how much energy you consume.

Price - 18k

Hello good morning everyone.
I’ve just spoken to the Jos guy this morning and he said I should take the battery to someone on his team here in Lagos to help check it out. He has sent me the persons numer.
I Will be updating the group on the outcome. Thanks to everyone for their concern and advice.

What exactly was your issue with the Jos guy? One of the cells of the battery I got from him 3 years ago has gone bad. He wants he to send the full bank back to Jos. I have not made up my mind yet because he is not responding to my WhatsApp messages (even though he is online) only calls.

Just connect in series...

Also, unlike voltage, current needs to be drawn. Even if your setup is supplying 25A isc, your Growatt will only pull the 22A it's limited to. You still lose some power but not much, since it's not like you'll be getting isc anywhere near regularly.

My SRNE has a max input of 13A but a 500v VOC, so I just ran my PVs in series.

Does it have wifi or an app for remote monitoring?

If you check my previous posts, you will see the issue I’m having with my battery. I’m still waiting for the from the guy he told me to go drop the battery with but you’re right, WhatsApp messages sent to him gets delivered but he doesn’t respond back to it.

Infact, I'm also at the Cross road on this subject matter, though it's already written on the manual that high ISC of the solar will not affect the inverter but my concern is that, why waste energy when I could get a with ISC of 13amps n below... abeg help share a with ISC less than 13amps

Hello Guys, has anyone tried this product from felicity?

Any reviews? Does it work with all products.?

This is not the USB version, it's comes with a serial and RJ45 connector.

Yeah, but I want to get close to that 6000w PV capacity. The best I could do is roughly 4500w.

Lol..same issue i had with my growatt 5000es, i could only use 4600w out of the 6000watts cos my voc don near 450v and if i parallel to drop voltage.. 22A isc wont allow. Anytime u find solution, let us know...Lol

No sir

If we're being objective, you probably will never get the max output of your s in Nigeria. When sun is out on full blast, temperatures also rise which then drops voltage.

It's more likely that you get NOCT Pmax, which is around 77% of your s' rated output.

If you're getting around 20KWh daily from your 6000w setup, you're doing about as fine as you possibly can imo.

If you absolutely need to get 6000w, then you just need to oversize your s as much as you can while staying within the VOC limit of your inverter.

Pretty much all the Jinko s will serve you. 580W has about a max amperage of 13A.

swagifted:
person house for florida...using enphase micro inverter... e CHOKE.

I think I'm counting up to around 250 units solar s on that sprawl of building. It may be more. Eachvoanel may not be less than 300w.

I'm helplessly envious. Damn!

The max you can get out of this 580w is 8 in series which is still 4640. Still far from 6000w. I want to go near to 6000w without need for an external charger controller.

Abeg, who's this Jos guy...you don't have to state his name in full and I won't quote the post so that it can be edited later

You may need to go for lower wattage, say, 255w Trina, voc 38v, ISC around 9a I think. You will be doing 12 in series and 2 set in parallel.

Dam5reey:


Attached is one of the functions.
its a Voltage regulator, Current limiter, Grid Delay, volt and current meter, and shortcircut protection.

Thanks for clarifying boss

38v * 12 Pcs = 456v still more than 450v, unless he connects 11s2p which should give him 418v

mctfopt:
Does anyone know of a solar up to 450w with 10A or less Isc? Please share the product name.

JA Solar 460w is around 11a

jonescosmos:


Abeg make una help me look at this again, maybe na my eye dey pain me or some cells are hidden under that bar. If so, who would do such a DIY? Anything that would cross the terminals of a battery cell is bad, no matter how insulated you might make it. Except say that Bar na plastic.

That bar is a clamp. There are cells under it. Its how most battery designer holds their cells in place.

I see lots of that.

Amador1:

No I don’t have a voltage meter with me except I ask around or I place an order for one.
My location is Lagos surulere

Can take a look at it if still interested.

Valto:

Nicely done.

I also had issue with one of the packs I helped someone to buy from him. 24v 102ah pack married to 4 pcs 350w monocrystalline via powerMr MPPT CC. It went bad before one year warranty ran out and I immediately notified him to which he was positively disposed to me sending it back for checks. But cos it happened during the peak of the sunny season, the problem only comes up when the sun is down and the battery runs down within 2 hrs on just 213L deep freezer which is the only appliance person uses it for. And since there was no immediate alternative to keep her freezer working while the pack is sent for repairs, she still hung on to it and kept managing it like that. Then came the rainy season the following year, which was already going to two years after purchase, she couldn't manage it anymore. So I had to remove one of my stacks of 24v 50ah lithium stacks and gave her to use pending the time it's sent for repairs. I have 4 stacks of the Lithium (self assembled) which I use so I'm down to 3 stacks at the moment.

September 2023, I called. He said he wasn't on ground in Jos but that he has his technical person on ground there and gave the details of the recipient. I spent 19k to send it to Jos using speedaf express so as to ensure careful handling. After three days, technician called that he'd repaired it and I spent another 11k5 to bring it back, also via speedaf cos I specifically demanded for that method.

After I received it, I was busy for about 1 week so couldn't even check what he did. The second week upon testing it, I was shocked to discover that ńa still exactly the same problem. As if the guy didn't open it up (although the warranty seal was broken sha which suggested it was opened). But walahi, na like say dude just kept it for 3 days and then called me that he'd repaired it without opening it up.

Dejectedly, I just packed it in one corner and hadn't bothered so much since the woman that owned it is doing well without complaints with the stack I gave her from mine. I chatted the Jos guy (not the technician o) up and he indeed expressed concern that the issue persisted and suggested we do the diagnosis together via video chat. But aswear, I never get time to do that since that time. To even carry the battery alone, cos it's heavy, ńa headache for me. So trying to hook it up to any set up for diagnostics is already worrisome for me.

Please note: This is the only battery that had problem out of the many I bought and referred to him. In total over the past three years, I gave him four referrals and I bought two for personal use from him. It's only that one that had problem. So he scored at least 84% assessment from me.

TechGeek777:

Oh, 500v was in my head. 11 in series then.

bassdow:

You don't expect I start arguing with you. Do you ? Because I wouldn't. We all are RIGHT in our own numerous ways.

Thanks

You're welcome bro.

We all learn new things everyday don't we? So it's okay to be open to updated facts and ideas.

My experience is quite similar. There was this specific pack that was sent back to Jos THREE times before a cell was changed to resolve the problem. About a year now and no new issue. All the back and forth could be distressing with all the logistic logjam in Nigeria. I have four of his packs in my house now ( 3 bought directly from him and 1 as being prior-owned by a member of this forum)

I have 7 different Lithium packs in use - a Felicity 15kwh, a Pylontech US 3000,a 7.5kwh, 2x6kwh pack, 5kwh and a 3kwh and he built 4 of those packs

You can go for 8 x 625w jinko s all in series. Attached is the screenshot of specifications

Dam5reey1:


You can get 24V 3.2KA, 2.9KW from Sako. At similar price or even less, I just completed an installation of such

Hi. Please can I get the link for this "Sako" guys? I want to check it their solar offerings and prices.

I'm hearing of them for the first time though.
