Boss, no vex abeg. I saw ur response to a comment on your YouTube page. In summary, you told the guy to use 14.2 for the boost and float charge setting, that it was an error from the Cworth technical team to have recommended 13.8 as boost charge, 13.6 as float.

I use a 200ah 12v Cworth battery too, and it's the recommended settings that I'm using.

Do you mind explaining the rationale behind your recommendation?

I'm new to this solar stuff, so I want to understand what I'm using.

Thanks for your efforts in answering our numerous questions.

Yes, Recently I help someone troubleshoot his set up, issues was with float Bug on some Axpert Hybrid inverter, If you set 13.6 as Float for example inverter will only charge to 13.6 and not charge to 13.8V at all.

Lithium batteries stays at 13.3 most time so there is not enough potential difference to push current into it if the charge voltage is set to 13.6V..

But 14.2 to 14.4V will increase the potential difference and more current will flow..

There is no way you can push current is the battery has same voltage as the charger.
Trying to break it down as much as possible..

So this person has been experiencing low power from PV, on checking i discovered the battery was set to Flooded or so on the setting 05, then I changed to USER and set Float and bulk as the same thing. Then there was an improvement.

If your Inverter does not have float bug and charges well at 13.8V you are good to go, But LFP can charge to 14.6V without any effect,
I charge between 14 ~ 14.4V to account for cable losses, so depending on cable loss on a set up, I compensate accordingly.

One of my Videos also demonstrate how the charging voltage affects the max power you can get from video.

Nawa o, this person should just come out and be straightforward about what Valto has done to him to make him become this bitter towards him. It’s well sha

Yes we're making progress. Are you all not happy? I know some OGs are secretly happy and if anyone is unhappy then bomb dey your head.
This is DIY not marketplace.

I need 7S BMS 80A. Anyone selling?

Can we go back to sharing tips?

I'm tired after assembling my 14.3kwh pack. Came in here to check what gives and all I see is back and forth about who sells the cheapest.

I'm here for DIY tips only and any other thing related to RE. That's all.

Anyways my 14.3kwh battery pack looks good

It's good to do it yourself. Lol

Thanks, boss, for the explanation.

Dam5reey1:
I have provided clear information, here without harming anyone.

If seller has the conscience to sell a certain Grade of Cell, he should be ready to defend and own it with full chest!

Not calling me hater of the brand I have my share of experience with.

I have provided enough information here, its left for anyone to Decern If I am marketing my own brand and discrediting another.

You are sounding as if you are being employed to act like quality control manager for this group. It is not your thread bro and you don't have such power.

Do your installations, do your online reviews, test whatever you want to test, and get paid bro.

You don't need all these.
You will only end up with more enemies.

Judging by the cost, it's not grade A, though they say it is. Who am I to argue? Lol

Dam5reey1:

I know you will defend it.
I wonder how ppu around you cope.
You rick of arrogance. Enjoy your decision.
Keep on.

Put location and phone number for the Cworth.

Dam5reey1:
This is what is obtainable in today's market..

5 years warranty on Lithium batteries.

This must be the cheapest brand in town now. Are they in the same quality range with the like of welion, Srne, c-wort, growat and others? Can both there batteries and inverter be paralleled?

This is a DIY forum and should be a free learning hub. For chrissakes see this local man talmbout "It is not your thread bro and you don't have such power"? Also, getting paid should be the last sentiment prevailing here. That's the notion some of us are correcting please.

Hmm. Correct me if I'm wrong but from this table, why won't I just get two 1.3Kwh 12v and in series ~2.6Kwh 24v @2x177k = 354,000
Instead of one 2.5Kwh 24v = 555,000

You don't get it.
Won't he get paid for installations?
Read it well.

To clarify, the Model number and cells are different.

I don't really fancy series, but you can do it, ensure to charge both in parallel to Full, before then connecting them in series, this ensure the pack are equalized.

Someone who bought it also did them same.

When in series, charge to 28.6V, cut off at 24V.

Where did you buy the cells from and box as well.
I am considering getting a battery box and eve grade a cells.

Hello house.

Just for curiosity, why charge then both in parallel? What is wrong in charging each separately to full voltage and then connect in series?

Resting time is not needed, having them in parallel or separately will take same time.

This just confirms your review of the cell in cworth 12v 100ah.If not ,why a whole #200k difference .It means certainly the cells are of varying quality. All the same, they still try.Nothing stops them from inflating the price to 280k and one will still think its average price of most 12v 100ah block lithium.The price still makes sense though.

You gerritt, not everyone is Dami, who will tear apart or even do capacity testing.

OK.I get.Faster than doing it separately. Thanks for clarifying

Different cell quality probably.
