Who did the audit for you? Are they available in Abuja

QuoteJust1nce:


Impressive I must say. Been following your setup for quite some time because I'm trying to use it as a benchmark for my own off-grid solution in a couple o' months. Thank you for listing your load consumption. It was very beneficial as we share almost the same load setup; just a bit different quantities as follows
1x 2HP standing a/c
1x 1.5 HP split
5 x 1HP split
7x chandeliers
No desktop machines
5x 15Ltrs w/heaters
about 200yards of LED lighting
No electric burners (gas only)
Kitchen hood/Smoke extractor
Electric gate and fencing
1x 1hp pumping machine
1 water pressure booster
1x washing machine

Everyother thing remains quite (almost) identical to yours. Pray tell, if we swapped loads, do you think your setup would conveniently carry mine? If you had my load setup; what would you add to your inverter setup to still maintain power autonomy without worries? Thanks in anticipation.

JK BMS now have data communication and you can link them all.

nicodemusic:


It's PZ.. Front view attached

nicodemusic:


Yes, the manual says hold for 10 seconds but I've held all the buttons for 100 seconds and no adjustable options come up. I can only view events but can't edit or adjust any..

nicodemusic:


I can't seem to find where to reduce the charging current as the [Enter] button on the inverter does not prompt any menu.

The batteries are Quanta Dry Cell..

I noticed the voltage getting higher and the current getting lower from 41A to 40A and now 39A. Perhaps the battery bank is very weak and the inverter is charging it aggressively based on the 3phase charging protocol.. I'll keep monitoring till as much as my fuel can take tonight and tomorrow I will continue.. Note: phcn is not available so it's steady generator so I'm charging it tonight with the generator and I hope this doesn't have a bad effect on the batteries.

nicodemusic:


Thanks again for all you do. I understand that i have to get 2 more panels and connect all as directed..

I'm currently charging the batteries with AC and I have attached a photo of the charge status.. My question now is the 40A the charging current or is it the current in the battery as shown on the inverter screen? I have observed for a while if the 40A will increase as the battery charges but it's been stagnant, sedomly fluctuating between 40/41A so I guess it's the charging current, which I believe it's quite on the highside

brightk:
pls check ur dm

brightk:
i may be tempted to ask

What load do you run on this beast and y u didnt go tru d DIY battery route.

13.5kwh is not as bad

nicodemusic:


Thanks so much for your detailed analysis.. Bottom line is ; should get 2 more panels? .. Would 2 more panels of 400w or 300w in this case (making 6pcs connected in 2s3p) generate up to 4.8kw or more required to match the battery bank?

Also I noticed my batteries sometimes shows 26v (supposedly charged state) but it would not take a long time before it gets to about 23.5, the inverter alarm kicks off and then shuts down.. Does it mean it's just showing 26v but not charged and therefore not strong enough? My load is always below 10% so I guess the load is below 500watts (since inverter capacity is 5kva)..

I just want to be sure if it's more panels I need or if the battery is misbehaving.. Thanks

nicodemusic:


Please review this response of yours.. You only described 5panels @ the bolded.. What connection (parallel or series) would I use to attach the 6th panel?

I'm considering adding 2 more pcs of 400W panels to it if that's what it would take to have a good charge on a daily basis. So far, I haven't been satiefied with the results. I have 2 12v 200ah Quanta batteries.. I particularly went for quanta at a higher price because I learnt it was better. I'm worried because my neighbor's system stays way longer than mine.. I guess cos I just installed mine and perhaps it's not charged.. Note: Neighbor has 3.5kva 24v setup with 2 12v 200ah felicity battery, while I have 5kva 24v setup with 2 12v 200ah quanta battery. Neighbour's uses 8pcs 200w panels while I use 4pcs 400w panels which I think it's technically same from calculation. I want to max out my options to determine if the batteries are the culprit so that I can return them ASAP.. Thanks everyone

nicodemusic:


Please clarify your comment and fix typos.. I currently have 4pcs 400w so adding 2 to it would be 6pcs so how it the connection going to be for maximum results? Also, why did you say I can't get the best out of it??

swagifted:
you suppose buy one electric vehicle de dump energy i tell you.

TechGeek777:


This is 90% of total capacity which is quite fair.

Did you use SPD for the inverter AC Output?

brightk:


What is ur pv capacity and type of inverter?

swagifted:
but wait, is it because of the low voltage that happened days back?

swagifted:
lol, u get light abi you no get light? This days if you see 12 hours na thanks giving

Good day professionals,
Can single core coleman wire (say 4mm and 6mm) be use?
4mm.... A output and input
4mm....pv input (about 8 pcs of 435w jinko solar panels)
6mm...battery to 3.5kva Growatt 48v ES.
Is Growatt better than felicity?

Good morning house.. Please I need some technical support on how to connect 4 pcs of 400W solar panels to achieve maximum harvest..

Available Apparatus

4 pcs 400w panels (specs attached)
60A mppt charge controller (Vmax 150volts)

I think it has to be parallel/series connection.
This is completely a DIY so any assistance would be highly appreciated.

isangjohnson:

Pylontec battery is more superior than lifepo4 battery, hence the price difference.
If the Felicity can give you quality lifepo4 battery with real capacity that can take you for 10 years, I would suggest you go for lifepo4 that has more usable capacity.
REASON: In the next 8 to 10 years, another battery may likely come out that would be superior than these two and you may likely want to switch over...... If you were to compare pylontec 4.8kwh with lifepo4 7kwh at the same price, I would chosen pylontec.
SUBMISSION:Human wants are unsatiable.

dollarnaira:


Baba it is about choice. As for me, I detest hybrid for now. Repairs, complexity, inbuilt cc can be pwm , if one part get damaged it means the whole system need to be admitted by a technician. How long it will take for repairs? Only the gods can tell. If you make use of lead acid and is taking too long to fix, sulphation will gradually set it. With non hybrids you can have different spares. Use your head sha.

swagifted:
where can one get this battery in nigeria.

Obnoxious2001:


This your budget .

You could have stated this first so @jonescosmos no for dey call big names

brightk:
12pcs of 550w in series is over 500v sir

Ferdiwar:
Please can you assist me with the spec sheet of the 625w panel you got.

I am working on expansion of my setup but the Longi panel I'm currently using is annoyingly expensive now (208k for 570w as against 165k I bought them in December).

I earlier went with the Longi over Jinko because of the current as the max current of my inverter is 13A, the Longi 570w have a max current of 13.03A while the Jinko 580w have a max current of 13.38A

dbshaywhy:
My plan solar system set up.

48v system

6pcs of jinko-solar-550w

3.5kva inverter, hybrid or stand alone with cc
(can you please recommend a good brands from the choosing option)

5kwh lithium battery

Please is there anyone that bought from fouani online? Apart from the site being laggy, after I made card payment I can't see my order anymore. It has been over 1 hour Order page is just blank. No receipt/processing and I hope I'm safe guys.

I'm not happy with the behavior of some installers.
Two months ago, dishtech whom I trusted was supposed to handle an installation for my client in Abuja but he went for outside work, which took him longer time to return to Abuja.
I came here and asked for an experienced installer and someone indicated interest and dropped his contact as well.
I called and linked him to my client. Instead of him to go and handle the job by himself, he sent his boys who didn't understand anything about the lithium battery, even as I was monitoring the installation through phone call to make sure all settings were done correctly.
I was surprised to receive a call from my client few days ago that the system had shutdown. I thought it was lvd disconnect. We called the installer and the installer still sent his boy, who went there and told me that the battery wasn't producing power.
I called Dishtech who went there and realized that the battery type was set to tubular battery and lvd was set to 40v. Meanwhile, I set the lvd of the lithium battery to 43.2v (2.7v each).
The installer has collected his money and the overall cost of repairs is on my head now.
SUBMISSION: We should be careful of those people we call for installations.

Dear fellow solar warriors, please persons that have used deye hybrid inverters in Nigeria what was the most common issues you encountered if any.

Juror:


Did they deliver them ? What was their delivery cost like?
