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

> I will always recommend Hybrid over External CC (Except for High-end CCs).

> For High end Inverters, choose among: Huawei, Schneider, Deye.
For Voltronic based Inverters go for: Growatt, MPP Solar, Felicity, Senre, (Many More in this class.

> If you must opt for external CC, go for an 80A to 120A CC. (e get why)

> For Battery (Patented): Huawei, Deye, Dyness, nRuit, Blue Carbon, Felicity, CWorth, ETC
> For Battery (Assembled): Contact @Valto straight away.

> For Solar Panels: Make sure 6pcs (I recommend 12pcs) will be enough to charge your battery to full while carrying your loads simultaneously.
Considering that Pmax (NOCT) of Jinko 550w is about 409Wp, 6x409=2,454Kwp, Which might not be sufficient for you on an cloudy day. But 12x409=4,908Kwp (Fair for daytime Charging and Loads), moreover 12pcs of Jinko in series is still in the safe zone for a 500V PV Hybrid Inverter during an STC.
Grid is no longer an option or alternative to dark or cloudy days.

Oh Johnson, so sorry for this terrible experience, but I will blame you a bit. You knew I base in Abuja, You know my capabilities, You have my number, you should have just rang me up.
But in all, has this issue been resolved?.
So sorry you fell into the hands of Engineers without Knowledge.

I had gone to correct an installation last year where an installer connected 2units of Felicity LPBF48300 in series, to 2 Units of Growatt which were in parallel originally. The instruction was to replace 8Pcs of Tubular Batteries with 2x LPBF48300. Thank God one of the LPBF48300 popped fuse immediately with a loud explosion.

The guy still went ahead and connected LPBF48300 in parallel later on without investigating the cause of that explosion.
The client later discovered that one of the batteries wasn't discharging and charging. And that was how I was contacted.

Moral: Be careful of Engineers without Knowledge.

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

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

Dam5reey:


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

dbshaywhy:


Thanks for your input... Am not always at always during the day from Monday to Saturday, except Sundays.
With my rough calculations, instantaneous load in the when back can never exceed 360w, while over the night, 80w with century rechargeable fan(mains will be on wen notice its getting low)

My budget 2.2M

Obnoxious2001:


This your budget .

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

jonescosmos:


oops, my bad, was actually in traffic while responding. I meant to say 12pcs in a 6 Series 2 Parallel is still in a safe zone.

Drgreatone:
Pls ogas in the house... For a 48v hybrid system using 4 220ah tubular batteries, whats the maximum charge current setting on the inverter? Was thinking 20amps was fine but someone advised I can go as high as 40amps. Wont this damage the battery in the long run?
Then wit the recent postings about high current mppts, does it mean a 60amps mppt wud pump 60amps into the battery connected under optimal conditions? Powmr for example only has settings for float/bulk voltage and type of battery but none for max current? Should I be scared? I av 1200watts of panels connected via it to 24v tubular system.

Bettybeauty:
Hello house,

I am a novice here. I need experts to advise on what I will need to power two 319 litres inverter freezers, 6 led Bulbs, charging of phone, and 1 TV.

How many solar panels?
Size of inverter and battery?

What will the estimated cost be in today's market?

I will appreciate any advise🙏

Thanks

Mid January when I wanted to mount my panels on the roof, I contacted (a so called) engineer to do the Job (I have phobia for height), via phone call without any information on my setup baba concluded that 5 pieces of 570w panels won't work, that it's either I get another panel to make 6 or I use 4 out of the 5 and that I need 10mm with for the installation I just ended the call and reached out to another person.

The guy that later did the Job later begged me to teach him how to set up lithium battery on the inverter as he was unable to do that on the 1st Deye inverter installation he did.

Most of the installer and so called engineers are too lazy to update their knowledge on the same things the practice.

Please, I need this urgently before price shoot up again please.....

NOTE: a not always at home during the day from Monday to Saturday, (inverter will be put on when in the night, probably 200w load till 11 pm and 80w with a century rechargeable fan which will only be connected to mains when notice is low), while on Sundays my total can never exceed 360w, hardly will it reach dt self,

A 43 inch lg smart tv 65w

Xboom 720 W RMS 80w

Probably a scanfrost freezer 150w,we are not a fan of cold tins

A small nexus standing fan 65w (sitting room)

And occasionally, 26 inches ox standing, if av visitor and crowded sitting room

what exactly is your question please ?

and if you looking for brand names, you need state your overal maximum budget

As you are planning to buy hybrid, plan for a good protection systems (earthing in particular).
Repair of those equipment is expensive.

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.
