Csat africa p-2000 inverter, 60a pwm solar charge controller (no get name ), wires 10mm

Wont be surprised if the issue is how ur panels are connected. If they were all parallelled with no shadowing or shades, u sud be able to charge ur battery full unless there's load running at the same time

Ok

I need a good 12v 1.5kva inverter with a good surge power and lvd.
I also need 60A PowMr CC.

I used boaster to start a 12v hybrid inverter for a client this morning. The lvd shut down the system last night but the inverter refused to wake up when the sun comes up in the morning.
When I checked the settings, the inverter lvd was at 12v and I've already set the bms low voltage cutoff to 2.5v and I confirmed it.
What could make the inverter not to wake up?
Does anyone have this experience?

Peterlove11:


No.... You just need an efficient system to charge your battery. Increase your panels or change your charge controller to mppt , better still you can do both.

any recommendations please? Thanks

Brand New EVE Cells available:

EVE LF280K, 3.2V 280AH
Tested capacity up to 300AH+

8 Cells and below 130K
above 15Cells 125k.

Experts in the house…. Which would you prefer… Fanless MPPT charge controller but with Heat Sink or Controller with fan. Some people believe controllers with fan equal parts failing anytime soon/Big damage to the controller if the fan stops working. While some believe controller with just heatsink tend to get hot often leading to a shorter lifespan. Which do you guys prefer and why?

From 280Ah to 300Ah and additional 20Ah added to each cell for grade B cell?
Na CAPITAL LIE.
Drop the evidence of your capacity test.

This is what my JBD BMS is reporting, what do you suggest I do based on this?

if not name the brand, and how long it has been in use? and have you tampered with any factory settings.

Oga, open up and let everyone understand.
If I've scammed you before, open up here.
I've personally been scammed in this cell business and since then, I've made it my mission to stop these scammers.
Some people (scammers) may not be happy with my post but I also know the disappointment and anger people has when they realized they have been scammed.

Don't bring YouTube into this place. Provide proof for your claim.
You said the 280Ah grade B cells you just advertised has been tested to be 300Ah.
Give the evidence.
I've sold different capacity of grade B cells to people here and I told all of them nothing but the truth.
I've also sold fully coupled battery packs with grade B cells to many people in this forum and I told them nothing but the truth.

You may not like to show a clearer picture of the QR code but taking a close look at the QR code of those cells, there are white stickers on the side of the cells which is a general sign that the QR code has been tempered with by sanding and re-lasered them.
Whoever wants to buy those cells should first of all remove the black cover on top of the cells. There is glue on them, we usually rub
alcohol with cotton pad and remove the glue....
I will drop the sample pictures......

I had similar experience a few days ago. I think there is an issue with your bms.
To confirm it, use your voltmeter and take the reading of individual cells and pay more attention to the cell 3.

Just change that BMS to JK if U want Ur sanity intact.

May I ask how you got to know it’s grade B by just looking at it in picture?

Imagine.

Dam5reey1:
Imagine.

Stop all these mental gymnastics you're doing to divert people's mind.
Provide proof of your 300ah capacity test claim from your BRAND NEW 280Ah cells.

I'm in the same business.....
Just give us time and let him drop the proof first.
I will reveal everything including the company he bought those cells from.

On the 21st of this month, he dropped a message in this forum claiming that his 5kwh lifepo4 battery powered a load of 4kw.
When I told him it's a lie because I knew that 5kwh was grade B cells, he said he would drop the video soon.
Up til today, I've not seen the video.

He came up again with another lies today to scam people.

@isangjohnson & @Dam5reey1, do you people have personal issues with each other?

Abeg make una take am easy oh, guys.

Oginidi?

I do not believe this post is for me considering that you responded to me further down. I guess you meant to quote another person.

Yes I built it myself.

I use JK on my other bank, I wanted to also test JBD. I thought JBD was also a good brand in the world LiFe04?

Okay, I will measure the cells directly. Thanks.

If it turns out that the readings are correct, do you think balancing can harmonize the voltages

Yes Boss.
But if the issue came from the bms, you may see balance cells while taking the reading directly from the terminals.

ojesymsym:

Good, open up the pack, remove the BMS leads, and test with a multimeter directly on battery terminals and report the results.
If you have same Voltages as reported by the BMS, then you need to put the cells in parallel and equalize them.
