This is the few info i can dig up

1. It communicate using RS485

2. The controller can be set to LiFePO4 battery following the steps in picture 2

3. If you are not tech savvy,you will need help pf a network admin for a RJ45 cable setup using the following images RJ45 x2 with one end working normally to goto PC RJ45 port while other is reconfigure

4.this shows the way to set the Rs485 pins for the charge controller and then you can do thing the way you want it

Please note: that this information is not 100% certain to work but 90% sure it should do the job right

Please do you have anyone in lagos who can help me configure it or set up the RJ45 cable?

It's likely the option will have a wind charge controller, is it? Or it's just a socket for extra inputs.

It's an input option

purplekayc:
which wind turbine etc is convinient for home use

Hmm.....good question which I don't have experience on.... however you first need to be sure you have constant wind in your area for a wind turbine to be meaningful....if you are in Lagos maybe you get some wind at the island not sure anything reasonable will suffice at mainland and into the south west axis

Yes, I do but not heading in the direction of the person anytime soon

Why not show this to those cafe guys

Growatt are working to reduce or eliminate power export to the grid and improve more of self consumption which is where Grohome their feature comes in

Grohome is a feature that uses varieties of smart devices like EV charger, lamps, socket, thermostat and a few others which will automatically detect and switch on appliances when there is excess power generated but not used to prevent export to grid

In this part of our hemisphere, for the main time
Working with google or smart devices that can work with it is the way to go for now especially with Growatt

With a Google home device, you can link smart lamps, smart sockets, smart TV, washing machine, microwave, AC and thermostat et. cetera with the Growatt app as a third party to control couple of these devices when you detect you are generating more using google assistance and a chain of trained routine, you can have the smart appliances work just by using words like "Good morning Google"

ojeysky:


Bros could you elaborate on how growatt does this?

Sorry boss but I did not mean it that way at all.

I follow your youtube channel with great interest. It is fun to watch you try out all sorts of new stuff.

I have not yet seen your Pylontech issues video but in my experience with Pylons the BMS positively disconnects after 54v.

Perhaps a combo of factors created a failure mode despite the BMS's efforts e.g Pylons paired with charger in open loop without comms, the BMS will always request the chargers to throttle charge rate from 0.5C to 0.1C once the SoC approaches/passes 90%. Without comms, the charger cannot heed this instruction and may keep passing larger than required amounts of current and ......

Havings comms between BMS and inverters/chargers is absolutely critical especially when deploying an aggressive design e.g large PV array with small battery bank, large loads and large inverter. I know that Schneider finally implemented Pylontech comms with their latest inverters, I don't know if that passed on to SCP and solar chargers as well. If one must do open loop, then one must set the parameters conservatively bearing in mind worst case scenarios and deployed equipment quirks and limitations.

Just random thoughts.

Good morning. Edit original comment to show what you meant.
Schneider has yet to update the older inverters. This setup is an open loop following the parameters as sent to us by Schneider for Pylontech batteries. The array is not overly big and the failure occurred on a cloudy morning. The BMS would normally limit charge which I have seen on an inverter that we remotely reset. It defaulted to lead acid and charged as a lead acid battery. The pylontech BMS managed it fairly well. The board would at worse case fail and the battery would not operate. This is not what happened here. We are waiting to hear back from Pylontech before we replace the batteries.

My Oga - I have edited my original comments for more neutrality per your guidance.

I have been forced to grudgingly support Schneider's open loop arrangement for Pylontech on two occasions now (client already bought equipment marketed as compatible) and found it inadequate - inability to communicate battery SoC limits you and one is left with only voltage based control - even the low battery cutoff voltage is not as high as desirable to secure 80% DoD.

If the Schneider chargers support cold starting and charging - ability to charge a zero volts or deep discharged battery, this would have likely been the cause of failure as they would simply keep trying to push energy into the battery until something gives.

In fact I intended to mention that of lead acid catching fires too earlier on but it skipped my mind. So catching fires is not the exclusivity of lithium chemistries. However my short stint with that 18650 fire made me know that it's not in the leagues of LA fires. It is potentially incendiary and putting out the fire may be the hardest (I think it is a class III - class three- fire which typically defies water and even the common fire extinguishers). That of lead acid isn't so common but not desirable nonetheless and the fact that it is related to the hydrogen gas produced from the vent brings some relief. I hammer it into the ears of clients, most of which are basically naive, that no naked flames near the batteries.

Even one was hell bent on having her tubular installed inside the cramped passage of her house. Being my street neighbour, I know some of her negligent attitudes so I explained why I am seriously uncomfortable with her suggestion leaving out that part about my observation. That I did pro bono installation for her doesn't mean she won't be breathing down my neck for setting her own house on fire. Of course I prevailed upon her to use LFP and still had it installed in her verandah with adequate ventilation.

What gives me some rest of mind regarding 18650 is its use in many commercially available battery packs like MTN lumous and BB jump thingy. And there has been no accidents with such widespread deployment. So once you do the connections right, the ills are avoided. If I have to use 18650s, the BMS must have temperature probes and use of resistor fuses is sacrosanct. In one instance like that I accidentally shorted a bank while connecting the wires, all those resistor fuses to that side burnt. Such relief.

Batteries don't catch fire for no reason except u shot their terminal,,
They are not petrol or cooking gas,
All these quacks. Upcoming technicians wet full these platform

What it means is 5kwh could be 24v or 48v but all 5kwh at thesame price. The power remains thesame.

Namzy:

I'm confused about this pricing: 5kwh 24v/48v for 560k

odimbannamdi:


Boss, who be the Jos guy? Abeg quote any of his chat

I'm right here Sir. Kindly check my post for prices.
Many thanks

omotoda:



I better start putting up my Luminous inverter for sale.The only reason I haven't gone Lithium is because of my inverters. The price sure makes sense when you compare it with Lead Acid batteries that will give you just 50% DOD.Full river battery as at my last check with the sole importer in Nigeria about 3 weeks ago was #155k for 200ah.So technically ,Lithium is better cost wise in the long run.

I have a 12v 1.5 kva Icellpower inverterwith adjustable settings lying fallow in my store.Does anyone know if this inverter can work with Lithium? If not what affordable and durable options are available?

The Good thing with our BMS is that it can work with regular lead acid inverters. We use LiFePO4 with configurations close to the lead acid batteries. It only implies you will be discharging to about 90% DoD. Which in the Longrun is better for the health of your battery. You go use am tire!

ceaser:


Even if it is 100ah, why not brand it 100ah rather than mislead people by false declaration, hyping and inflating the capacity in order to justify a price tag?

Anyways it's Nigeria, SON is moribund.



You no lie about that Jos guy offer.



As at last the time I got a 24/100 from him January, it was for 270k. But it's more expensive now. He blames the worsening naira-dollar exchange. He also admits to have upgraded the BMS in the 24v to Bluetooth enabled one, of course with increased cost too.

So I believe it will now be around 300k.

Edited:

Guy, you don dey Nairaland. .
You kukuma want to dey do the marketing in the first person.

I'm dumbfounded by the reviews I'm seeing here. I feel very emotional. First of all I can't thank you guys enough for your honest reviews. We have good people in this country and this affirms to the fact that honesty pays. I'm still learning how to use Nairaland but I'm all over the place already. I will ensure to maintain the good reputation and deeply appreciate all of you. Never met you, but u have marketed for me already. One love...

I'm planning to procure this particular item in the coming weeks, but the 48 volt and 4000w continouos. Intend to have it as a standby 48v inverter.

By the way, yours appears cheaper. Can you post the link to it here?

Please how do intend to pay for this item considering the 100USD monthly spending limit on nigerian bank cards? It's been a challenge lately, the restriction prevents me from buying stuffs above 100USD or do you use a dollar card?

You have to message the seller and intimate him on your dillema. Of course he will likely know what to do, but you can suggest if there is anything he could do to help. Usually two things:

Some sellers have 1usd listing tagged "shipping" or "extra payment" on their stores. So he will give you the link to that and you can first pay 100usd on that link by selecting "100 pieces", then you use another card to pay up the balance of 12usd also on the same link by selecting "12 pieces", to make a total of 112usd. Immediately all this is done, you should message the seller so that he will acknowledge that everything is done accordingly.

On the alternative if you think you have only one card, wait till 30th or 31st of the month to make your first payment, then in less than 24hrs by the beginning of the new month, you already have another 100usd limit and you can pay up the balance.

Other ways the sellers handle this is reducing the price of the item that will already be in your "unpaid items" folder. You need a seller with good English communication and fast response time to do this. He will reduce the item price to 100usd (only you can access that reduction). Then as soon as you do that, usually in less than 12hrs before the price is restored by the system, you inform the seller. He will then ask you to pick a random 12usd item in his store to complete the payment.

One instance like that, the random item of 9usd that I paid for still ended up getting shipped to me by the seller alongside the main item. One "thermocouple wire sensor" like that. I don't even think I'll ever have any use of it.
