Depending on the result after the manual equalisation

Trippledots:


1. Change your panels location to optimize pv harvest, also increase the number of your solar panels
2. Confirm your installation is well grounded.
3. Of tubular and sealed lead acids, I prefer the latter. But some people here will argue that lithium is the best way to go. I still use lead acid anyway.

Cheers.

Happy sunday everyone. Out of curiosity, i got a multimeter... i have 4 batteries connected in series..after testing all came out 12.2v except one which came out 11.8v. Note that they re not fully charged as i have used them b4 testing... my question is, are they not suppose to discharge on thesame level??.. as same 12.2v for all??

brightk:
Anyone with experience using poly panels for installations.. what are the cons and pros of using dem as regard to mono... I heard de are less efficient than their mono counterparts

TechGeek777:


Big boys inverter

Dam5reey:


As expected..
This is a normal behavior when your batteries have degraded.

Swap the battery and you will notice the same thing with the other batteries as well. The positive end will read 11.8V.

You batteries have degraded.. start saving for new one. Or go Lithium for peace of mind.

Mostly is advisable to use battery equaliser for a 48volt system cos of stuff like this, normally what I do on site when I want to install 4 battery is that I will parallel all battery with a DC cable first thing first, then continue with other activity, I do that to balance the battery voltage to prevent issue like this. Once the battery with 11.8 reaches 11volt, then ur inverter will start buzzing. To solve the disparity in voltage, disconnect d 4battery from the inverter n charge controller, place them on a spacious place, get a 16mm DC cable n connect all Positive terminal together n do same for Negative terminals too... but u have to be extra ordinarily careful when doing it cos d positive cable mustn't come in contact with the negative cable or better still, get an engineer to help u with it. I base in Ibadan in case u also resident here

Same way I stil use HDD, even when most swear and preach SSD. Don't be surprised, most went east, not because they know why they're going that direction, but because it looks like most are going that route

IYGEAL:


Wasn't as pricey as it is today when we bought them.

IYGEAL:


Do you have reason why you still use HDD though?

bassdow:


you mean Lithium batteries don't degrade ?

Dam5reey:


Read between the lines.. I am recommending lithium in case the batteries he is having already degraded.

bassdow:


Yea and most of those reasons, are what you would call CONs.

To me SSDs have got there place.

Also data recovery is much easier on HDD, than SSD

bassdow:
Thanks for this. Recently recommended my charge controller to someone, when I go find am for market, the few places I saw it, the price go make you change mind.
It's same for a lot of other quality items. hence reason there are lots of rubbish in the market. If na by quality, a lot of shops go don close because customers no go dey.

There are lots of PWM charge controllers advertised as MPPT.

Another reason I dey pity those buying all these coupled and packaged lithium batteries. Quality lithium cells are pricey. And there are lots of overRated lithium cells. How many of us sef know wetin 18650 , 21700 , 46800 , etc mean ?

bassdow:
Anything anyone says here would be highly opinionated. Why not use google ?

That way, you get to learn more than just your question.

Myself, by default, always use MoNo. I equally tends to avoid those fancy (including very Black) ones also.

brightk:


This one u de throw shades from sides abt coupled lithium bstteries . Come out n talk 2 us directly lol.

Penuelseun:
The guy knows almost nothing about lithium chemistry, just copy and paste from Google. Who still uses li-ion for diy these days. People that have never coupled or installed an inverter or electrical system before will just come here and be forming overnight guru

Me still dey inside 18650 oo plus LifePO4.
If you have ur way with lithium ion u go fear.
You sold out urs back den probably u didn't do proper balance to max it out.

i i 4 don assemble small pack.. the safety precautions b like text book vol 1 vol 2 vol 3 vol 4 haba..

How many pieces u get?

dollarnaira:
SSDs are generally faster and more reliable than HDDs, but are also more expensive. If you need fast boot and load times, improved overall system performance, and can afford the higher cost per gigabyte, then an SSD is worth it. If you need a larger storage capacity at a lower price, an HDD may be the better option.

Copied.

I have tested the above in the days of running python. While my friend's hdd was struggling to load, mine open under 15sec. SSD no b HDD mate; same as lithium not being the mate of lead acid. You can only compare what you have tasted and used overtime physically.

ojesymsym:
I don't know about reliability o. My SSD failed up on me in the middle of a project. In short, the HP SMART feature started reading error with it and made it a real only. Anything you save will not be there on the next booting. The luck I had was that I had cloned a HDD because I wanted the much tauted speed of the SSD. I had to fall back to that SSD. In all my years of using computers, I am not sure any HDD has failed on me while inside a PC. They may fail as external but not inside a PC.

Now I want a hard disk and I am still thinking if I should risk it because I do not know if it was a one-off or it is a prevalent situation.

brightk:
premium ssds are a little bit pricey. Wetin full market now na shinko. U go see 3yrs warranty on top label. Seller go say e nor gurantee dat one.

brightk:
no one 4 now sef. i b say if i buy some items i go pick up some cells join to arrive by jan or dec sunce we still de oct. But this safety tin ehhh unto li ion e get as d tin take de. The pcb boards de make money de increase. Dollar is not smiling with anyone. DIY route com de won b like factory assembled pack. Na small 24v 100ah i feel like do sef. I b see some clearance sales 4 samsung cells dem cheap but mah small

dollarnaira:


Are those Samsung cells still available?
I doubt!

24v 100A is not a small pack.

The Samsung cell is 2.6A not small.
