1. Keep that PWM charger away from your lifepo4 battery, please. You can get decent MPPTs that are cheap and still charge lifepo4 without issues.

2. Any if the notable brands should be able to charge Lifepo4.

Please for Heaven's sake, recommend 1or 2

HeavenlyBang:
1. You're running a 40A connection? What charge controller is that?

2. 40A DC requires ~8mm wire at least.

It's an hybrid inverter, 60a mppt.

The inverter is a 12v inverter with a maximum voltage of 50v, meaning I can't run the 3 panels in series because each panel is about 25v.

Is there a way I can run the panels to produce at most 30a?

KA24DETT:
Thats not true.. 8mm copper is overkill. 4mm pure copper will serve fine. Unless its copper coated and not pure copper strands

KA24DETT:
with 50v. you can only use 2 or buy another one to make it 4. You cant use 3.

Nteogwuija:
Okay, thanks. I'd have to buy another panel then. Meaning I'd connect 2 strings of series to a parallel line, right?

KA24DETT:
Yeah. get another panel and connect it 2s2p.

dollarnaira:
Did you get him well?
Abi na me no dey see?

Each panel is 25v

Best alternative for now are 2 panels in parallel.

Series of 2s 2p is 50v already which is his max cc.

realpoacher:
How much for 12v 200AH?

maklelemakukula:
AI told me so bro. I, a mere mortal, am not very knowledgeable in this field

KA24DETT:
He is fine because you fail to account for temperature coefficient. He is not seeing 50volts bro. Most measurement are under STC.
Remember when the Charge controller is under load, voltage drops. Yep, he is never seeing 50 volts

jonescosmos:
Please make sure you followed the instruction as stated on your user manuals.
Secondly, It is advisable to always restart your Inverter and Battery when changing protocols.
I would recommend that you also get another patch cord (75cm Lan Cable) to swap out your communication cable and see if it resolves the issue.
Also make sure that your systems (Inverter and Battery) are properly grounded to avoid ESD damages which is common in this field.
If these does not fix the issue, Do it my style.

YANK BOTH THE INVERTER AND BATTERY TO YOUR VENDOR'S OFFICE AND HAVE THEM PROOVE TO YOU THAT EVERYTHING IS OK.

Yes because sometimes these devices may have a factory defects or damages inflicted during logistics and the supplier will always tell you that you might be doing it the wrong way. So I would swallow my pride, storm their office with the device and have them assemble it in their office and most times it turns out that i have been right all along, so they will try to convince you to turn it in for service.

maklelemakukula:
Ask them to send their tech person over.
Also, can you please share the quotation for the materials you eventually got for the installation ?

kristien4:
(1)Connect from battery PCS port to inverter BMS port
(2) Use protocol L51
(3) Your dipswitch settings, number 1 should be on why 234 should be off.
This is how i connected my growatt hope battery to my Growatt Inverter and it works well.

burnerr:
Please find the receipts attached.

Adding to my prior issues, i can't get the shine wifi to power on. It came on but I couldn't configure it the first day. Since the second day I plugged it, it doesn't come on anymore.

Edit: Does anyone know where I can get a spare BMS cable?

burnerr:
I contacted my supplier and they hooked me up with one of their installers, after hours of debugging there was no solution and he told me that my cable might be faulty then before the call ended told me that my installation does not meet their standards due to not having a breaker between the battery and the inverter and also using an incorrect breaker in my installation meaning if my system is to develop a fault it won't be covered by warranty (which I think he said to try to stop me from claiming warranty rights).

Allem:
Try know how many amps the jbd BMS be
Secondly you can't compare jk BMS to JBD BMS. Lastly JK display screen with a lot of information can't be place with regular alaba DC voltage meter.
Iron box etc.
Na this my few points make valto 100 amps reach that e amount

JJacko:
You nor get point, sorry.

omotoda:
So what exactly is your own point? A lot of people have patronised Valto here and never complained.If you feel his item is too pricey for you,just pass. You can't compare the economies of scale of Chinese manufacturers with an entrepreneur in Nigeria.I recently bought s 48v50 ah from him and I am impressed with the build and look ,even though I am yet to connect it as it's for use in another location. Don't try to bring down the hard work of anyone,e get why!!!

JJacko:
The major point of DIY is to reduce costs to match quality. We shouldn't be in the business of pushing pesin market to the point where it gives the chance to turn around and chop people head.
For someone that built his business on the back of this thread/forum, Valto is greedy, call a spade a spade. And never talk about build quality in the same sentence again.

Valto:
mr hater, u no de tire? better use your real popular moniker on this thread for this..
i don't have 12v 100ah in stock, so what is the fuse about
what i have is this 12v 142ah 1.8kwh made with JK 100A 1A active balancer Bluetooth bms for 399k vs the quoted 12v 100ah 1.280kwh made with 100A JBD Bluetooth bms. 290k.
your common sense will tell u the cheaper one!
