Anyone with Victron charge controller?

I have epever 60ah used

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

I reside in both Lagos and Ogun state (Around Sango Ota). You didn't state your budget. Wouldn't want to disturb the client unnecessarily.

There's
Kartel 5kva 48-volts (Minimum 4-batteries)
3.5kva 24-volts
2kva 24-volts
2.5kva also.

The 2.5kva are of different brands including Felicity and groWat.

My contact is on signature should in case you okay with the difference in distance. Also the budget I asked of, is to help talk with owners first, rather than constant to and fro

I have a 24v system not 48v
Talking about the budget, that has to be open for discussion and that was why I stated used.
I have to know what price the seller is planning on selling before knowing what to offer and if we can reach a deal then cool but if not then we may deal some other time.

Tbf the title of the thread says nothing about DIY. And DIY doesn't necessarily mean coupling everything from scratch yourself either way.

Our understanding differ.
Simple!!!

Dam5reey1:
Its still DIY, but you mean Lithium batteries, cause no one was doing DIY solar panels or inverters.

DIY battery is now expensive compared to ready made.

To you it is expensive
To me it is cheap and sure of my cells.

bassdow:
yea No be when dem Cut tree e dey die.

If it can't handle it, it would have burned at that first instant.

well to be fair, it doesn't often happen at just first or 4 attempts. Also the duration, and Capacity of the Solar panel matters also.

Me don mistake before where I connect Solar panel to battery port.

You can't compare effect of 20pcs of 555-watts panels vs 4pcs of 300-watts panels. The effect would always differ.

Haven't had a bad charge controller via that method BUT it's something one needs be careful about whether you using quality brand or not

Depends on the capacity being built. The bigger the cells (up to 314ah IMO) the cheaper it is to DIY.

Funny enough, DIY is not inherently CHEAPer. You just pay in some other ways e.g time.
But you know the satisfaction when you built (or coupled) something yourself, for any slight issue, you know where exactly to touch.

In building a House, One got 3 options
1. Buy ready made Sandcrete blocks,
2. or go through the process of molding mine which involves getting required quantity of Sharp sand, optionally stone dusts, Bags of Cement, water source, block mould, hire labor (or do it myself), and still get to supervise things myself.
3. Buy an already built house

Now depending on the value of your time, You could either go for option 1 or 3 or 2. The final quality depends mostly on what option you took, among other things. As for costs, that's an entirely different ball game

Pls any idea how easy it will be to get this Lontor DC fan Charger Circuit replacement?

How much could it be? The man here in my street is telling me 20k.
Can I get it at Ikeja or Arena?

@bassdow and co pls

Epever is difficult to integrate into the victron system.

Actually, a lot of the epEver's out there are kinda old version. To configure them for Lithium, means you would have to use the USER config where you get to set the actual values. Probably the newer models have direct Lithium battery support.

20v charger suppose full market na. Alternatively, show this to an electrician - make He help you repair am.

Also, a 19-volt or 18-volts [laptop] charger should work perfectly

Circuits such as this, ain't battery friendly at all.
Do you currently use Solar ?

Yes I use solar.

I burnt this circuit unknowingly. So I just need to replace it. What do you think?

I am technical to an extent, so kindly pardon my naivety. Do you imply here that I can actually use a direct 18V or 19V charger and discard this circuit? Then run the terminals directly to e.g., a spare laptop charger, and it will still work fine? After all it serves the same purpose?

NO

What I meant is that a 19v or 18v laptop charger can replace that 20v charger of yours without issues. Please don't connect directly ooo

if you are technical enough, try reading output of that circuit board - Could be 12-volts, or an electrician could help you check it even while it's bad.

if output of that bad circuit board is 12-volts, then you could easily replace it with a charger of smaller voltage e.g goTv charger, etc

Now you said You use Solar power. In that case, do you use Lithium or Tubular or normal Dry/Gel cell solar battery and what's the voltage of your battery bank

I'm sorry but at times I make mistake because I respond while heavily multiTasking at work.

Share with us the image of where you removed that circuit board from. We need to be able to know it's output. That's what would decide what we replace it with.

Also if you use Solar, and not Lithium battery, kindly do let us know

Lol, one wrong thing with the Terminal or BMS, it wont be same story.

You've got multiple options
1. Buy another in the market
2. Give it to an electrician to repair
3. Check it's output (might even be written on it's board, or the point you disconnected it from) and replace with a charger (which you might already got lying around) of similar voltage
4. Use Solar - depends on your battery type.
5. ...

I use a locally produced (Joshnka) LiFePo4 battery system. My appliances are connected via AC through an inverter. This fan is a 12V DC input Lontor fan. But this circuit Board clearly is an AC charger that helps takes only 12V and few Amps to charge and power this fan. I happen to have burnt it while testing it on an 18V DIY battery I built myself.

Now you actually made a nice suggestion about using an external charger and I have a feeling that that option will serve. In this case I need to get a 12V AC charger and connect directly to the DC terminals wires depicted in the attached image below. Or what do you think?

bassdow:
WHY

Cos i asked nicely 😁😁

Hello all. I noticed a battery voltage irregularity between my inverter and the battery a difference of about 0.9v. is this normal?

Since you said the Fan has a 12v DC input, I want to guess now the Fan is open, that port should be on the Circuit board that's not burnt. if Yes, then just use a 12-volts charger BUT if said port is on the burnt board, then don't.

As for the Solar, since you use Lithium battery, would suggest you don't tap out current from it so as not to unBalance your cells. We would take a look at that later

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
