Good morning

Please if I discharge my battery till BMS shut down, how do I start it again? Will the inverter connected be able to wake it up and resume charging? Or I must use a separate dedicated lifepo4 charger?

Please how do I get it done? The bms of Haisic is limiting charge/float (27.2v/26.6v), and from the info you it was recommended to drain till bms shut down. Please how to I wake it up? Thanks for your reply

These things are automatic. Battery gets discharged, it goes off. Battery sees charge it comes on. No need for manual input to do either of them. Unless there is an issue.

are you in abuja?

Do you have a victron charge controller?

The portion marked in BLUE clearly shows it's a 12-volts panel.

if the area marked in RED is the 12v input port, then you could safely use any 12-volts charger e.g goTv charger on it.

other than the wire you holding on the left that's clearly coming from the burnt board, are there any other wire(s) connecting both circuit boards together. Just being careful so we don't make mistakes.
Although the worst that can help is the fan becomes a single speed Fan BUT that's only if you don't communicate clearly with us

Thank you for your patience and your willingness to help Chief.

•The AC charging port is actually on the Burnt Circuit. The part you marked Red is not a port at all.
• No there is no other wire(s) connecting the Burnt Circuit with the main Circuit Board

After a careful look at it, I can confirm that the main Board that is not burnt is actually where the fan motor, communication, etc are all integrated to. The burnt circuit is just for Charging Purpose. Meaning that I could indeed get an external 12v charger for it like you’ve advised.

This is the charging port on the burnt Circuit as well as the AC cable for more context.

Yes that's right. A 12-volts external Charger (e.g goTv Charger) should work.

Also if your Solar is a 12-volts system, you could tap from it BUT ensure you do the tapping from the part going into the inverter (after the BMS, not before it), not directly from the battery else the BMS fit confuse and loose balance.

I'm guessing the Fan's battery is 6v. abi na 12-volts ?

This is the 2nd time you’ve mentioned something like this in the bolded. And I am curious to know more about what you mean. The system actually have a direct Dc ports of 12Volts and 19volts but I rarely use them. If by connecting to these ports, do you mean that it causes imbalance in the battery pack like you mentioned in your previous comment? And does it also have an impact on how quick the battery runs down or not? Cos I have also noticed that connecting to these DC ports on the battery pack runs the battery on a different Voltage discharge curve when compared to when I use only AC connection via inverter. And I usually have this superstitious belief that running directly from these DC ports connected to the battery pack actually drains the battery faster than using an AC connection via an inverter.

And yes, the Fan’s battery is 6V. Thanks Chief.

Firstly, you can safely replace the burnt circuit board with a 12v charger and call it a day.

Also, As for the Direct DC port of 12volts and 19volts, if those ports are on the Circuit board that is not burnt (the area I circled in green earlier), then you just could use those ports BUT ensure those PORTs are directly on the unBurnt board, and not relying on the burnt board which I believe it's not.

Basically the purpose of the Burnt circuit board is to stepDown the 230v AC source to 12volts hence you could do away with it.

Don't forget, if your Solar battery bank is 12volts, you could just forget about buying any charger and tap from it; essentially replacing your Fan's 6v battery. your Fan actually is 6volts but make we stop here.

If you still no understand, call me so I ask questions that would give me less reasons to ask questions. Verbal communication beats all these plenty typings

I think I just understood what you meant @ the Bolded. Well since your Solar generator already got a 12v and 19v ports, then you need not worry at all as you've got a charger already. Na to use wire connect them together. Would suggest you use the 12v port to reduce wastage as even the Fan no need up to 12. The voltage high up to 12v to give room to battery charging while using said Fan

Now I understand you perfectly Chief. And thanks a brunch for your help. I appreciate and admire your technicality 💪.
You just saved me from this technician here that doesn’t want to understand the situation of the country.

I'm not an expert like yourself, bro.
But I think you are not totally correct.

I have 2 batteries that when you hit the BMS cut off voltage, it won't come ON when there is charge. You have to bring it ON manually.


Does that mean the batteries or BMS is bad?

bassdow:
na Nigeria we dey na. Wetin you expect. I don complain I don tire. Me kukuma dey do ma thing on my side though na the DIY carry me come.

Normally, all these large boxes of Lithium batteries wey there adverts dey flood here, someone ought to have shared how to get reputable sources abroad, ship to Nigeria, how to use wood or PVC pipes to make the battery holders, this and that and have your own low cost quality (or at least average) Lithium battery.

Even Me sef don try do ma own Charge controller though gave up along the way. To make PWM easy, to make MPPT na another thing BUT imagine if there were others with same or similar goals

U can build a full mppt, if you don't want to program it

If you have an ok BMS, it should come on by itself.

If it doesn't, BMS may be of low quality.

I know I could have achieved better BUT Man no dey get time like before. Nowadays, except really necessary, I just buy so long it meets my standard.
Probably if someone has done it before, it would be easier than cranking my head for a first time.

You can do it so we don't get to crack our head .

Probably you can create a thread, let everyone contribute then boom the design should be ready

Boss. Please I need your help ooooo. I need una help o. I hit low voltage cut off for the Haisic 25.6v 8kwh battery and now my battery just shut and wont start. Does not come on. Power from grid wont charge it. Please how do I wake it up 'MANUALLY' like you said. Please Bro. I nor knw say this thing once e reach lvd go shut down totally 🥺

an external voltage source same with the battery voltage will wake it, which type of inverter are you using?

Penuelseun:

Hybrid Powmr 4.2kw

My 2 panels was connected to a separate CC, but I have put it to the Inverter now, hopefully day time, solar power can wake it? I am so unsettled.

Bro, you mean an external battery charger will wake up a battery with shut down BMS? 🥺. Help a Bro

JK BMS? Okay.

Not this particular battery, boss.
And by manually, the batteries I was talking about has a smart BMS and you need to turn ON discharge option again to allow the inverter/charger to sense it.

Wait for today's sunlight first.

I use a JK BMS.

Comes up every time it drains when charging is applied.

hello bro how long does your battery last? I am looking to get one.

we're way past asking this type of questions here. His battery is 280ah 24v battery which has a capacity of 7.2kwh.

The total wattage of your loads will determine. How long the battery would power them.

Update

bkuranga sent me what he found online that the Powmr all in one inverter like mine has an inbuilt lithium battery activation function. So i went back to the manual and found that if i change battery type from user to LIL/LIP while on Grid mode, the BMS would be activated. I did that, the inverter activated the BMS, now battery is up.

Thanks for all the contributions.

All good, the OP managed to solve this issue now.

Any installer here that resides in Abuja??

Tdoctor:

i have one... Bluesolar 150V/70A. But i want you test it and approve cause its used... Its actually paired to be sold with an 8KVA QUATRRO .... But i can sell separately.

Unfortunately, this won't work for me. I need the newer models.
