A quick one.
Please is this an inverter AC? What brand, model and what's the power consumption like when the compressor first kicks in and after the room has reached the set temperature?

Thanks.

My AC is the regular AC, bought close to 10 years ago. The power consumption depends on ambient temperature. When the weather is hot, it consumes more power.
I haven't seen any significant initial surge as I see with the pumping machine. When it came up yesterday night about 11:40pm, the starting power was 1457W which came down to 1421W at about 1:20am when it went off. Earlier yesterday in the afternoon, the starting power was 1588W.

Hmmmmm? Like seriously?
Well what you just talked about has to do with your Raspberry PI Distribution Board or Smart DB or even some bunch of programmable timers in conjunction with your Dry Contacts, Perhaps you could tell us with visualizations how your Battery SOC between (30%-80%) would be a determinant for the behavior of your smart setup.

It is smart world, anything you can measure can be used as a condition to start or stop something. Let me just share a snippet of my water heater control.

Bonus: You can see that when my water heater is about to come on, my AC (ACSolar) is first switched off.

sharks776:


You fit try. Let us know if you succeed.

You are obviously limited by what you are exposed to.

In my house,
The pump fills my tank between 4am and 5am.
My water heater comes on between 5am and 7am. If my battery is fully charged in the afternoon, the heater comes on again between 1pm and 4pm.
My fridge/freezer comes on at 8am and turns off at 5pm.

Everything controlled like clockwork with Home Assistant and Node Red.

ojesymsym:
Person non fit use python achieve all these things?

Even more. If I have Deye, I wouldn't even use its smartload function. I have much better control with my smart setup. Unlike Deye Smartload, I can shed high load selectively. I can power fridge and freezer without powering any other thing. If I want my freezer to stay on, when freshly filled, I can just set that. I can power pump without turning the heater on.

Smartload is for people who don't know that better options exist.

Oga, Starlink is not MTN or Airtel , the grandmasters of deception.
Unlimited is unlimited, use 100TB if you can within 30 days; 500TB if you want,
The worse case scenario; your speed might be throttled after hitting FUP.
But guess what, Starlink doesn't throttle Nigerians yet and when they did in their country,
speeds dropped to around 30Mbps. But dey browse dey go till you quench.
They actually have a very detailed legal documentation page; but as a "lazy youth" that you are; i know you cannot find it.
. Do your research, I will not help you.

So, what is "priority data 40Gb" if Starlink is truly unlimited? https://www.starlink.com/legal/documents/DOC-1469-65206-75?regionCode=NG

My fibre connecrion is truly unlimited in terms of data cap. I can do 100TB if I have the need and the time for it. No FUP at all.

For zero, you cannot have an efficient home server
For one. you cannot stream 4K
For "two", download an 50GB engineering template and tell me how long it takes you to complete? mins? hours? days?
For three, You cannot have your kids, you, wife and guests streaming HD at the same time. Some devices will be throttled based on QoS
and the list go on.

What kind of home server? If you are running a busy website from your "home", you are not a regular home user. I run a smart home server and online DVR at home and my 20mbps work perfectly.

I stream 4k regularly on my 20mbps using Youtube or Netflix. Youtube requires 15mbps for 4k while Netflix requires a little more, but with precaching 20mbps is more than adequate for 4k streaming.

I download things well beyond 50GB using torrent or direct download, it takes time. If you need to download 50gb "engineering template" over short period, you are not a regular home user.

My home is not a cybercafe. I don't have all members of the family streaming HD movies on different screens all at the same time. I wonder how often this also happens in your own home.

Of course a gigabit link will solve all world's problem, but unless you have a special need for insanely fast internet due to the nature of your work, 20mbps is good enough.

QuoteJust1nce:


20Mbps is. not fine. Why are people so resistant to change? When Edge came it was fine yea, but then we moved to 3G was was good enough. Then 4G which was perfect "according to your stance" for most users. But then 5G arrived. If Edge was fine, why was the world gunning for more powerful internet tech. It's simply called tech advancements.
Stop that BS of 20Mbps is fine. In most advanced countries even 100Mbps is now archaic no matter if you want to use 1GB per month or 1TB per month. If it was left to people like you, the world would still be stuck with antennaed phones and GPRS.

So, tell me what your 100mbps is doing that a regular home can not do on 20mbps?

QuoteJust1nce:


It doesn't matter if he only uses 10GB per month; Nobody in 2024 should be subjected to a 20Mbps internet speed.
It's like saying he doesn;t use too much data per month; therefore he is good with 3G. But people who use too much can stay with 5G.
Nah brov!

Nigerians and their bragging. 20mbps is fine for the overwhelming majority of internet users. It will do Youtube, Netflix, Prime Videos etc fine. I know because I'm using one at home with fibre.

With fibre all over Lagos for which entry fees are less than 100k, I had asked myself why people are rushing Starlink. When the thing first launched in Nigeria, I repeatedly tried to buy, but I kept finding it difficult to justify that expense especially since I have a good fibre connection that I pay less than 20k for per month. It is also unlimited and there is no FUP. It is 20mbps for one whole month and I have pulled over 1TB data in some months.

Besides, the report I'm getting is that the 100-300mbps is not always guaranteed. I have seen people with 40mbps download. I don't see the noise about Starlink if you live in an urban area with access to high speed unlimited fibre connection. I can not justify paying extra 20k for a bandwidth I really don't need.

Juror:

If one has an inverter with dry ports that get signals based on the SOC, it's just a matter of relays and contactors + timers and one can replicate that. Which is why I love the latest jk bms features.

True, I used to do something like that when I was using Outback.

twinskenny:


Can this smartoad work with srne inverter?

I doubt it. The Deye Smartload system takes advantage of the dedicated Generator Port by converting the Gen port to output under certain conditions. So, it will require that you wire your heavy loads to the gen port. If your inverter does not have this baked into its software, you can not use it even if you have 2 outputs. However, you can achieve the same thing in different ways.

For example, what I did is to put my large loads including AC, Fridge/Freezer, Water Heater and Water Pump on a smart relay that is controlled by Home Assistant. They can then be programmed to work only when battery SOC/Voltage/Current is between certain levels.

Hello @adrusa,

Please assist me with how you were able to connect your Felicity CC to MPP solar's MPPTracker and read the stats. i would appreciate if you could explain how you achieved this.

i am looking for a way to get data off my Felicity Charge controller and may considering selling off my felicity inverter cuz i cant get data off their ports or even find a device that can connect to it.

It is straightforward, just connect and fire up MPPTracker, but there is one little snag, the cable pinout appears to be unusual. You may have to modify your RJ45 to serial cable according to the pinout I previously posted here. If you are using a usb port, you also need a USB to serial converter.

Or you could use ESPHOME if that is something you are able to do. You can follow the guide from here: https://github.com/syssi/esphome-pipsolar

nicodemusic:
Good morning house.. Sorry to bother you guys.. I noticed these ports on my inverter and got me curious what's it's used for.. There also one like this on the charge controller..

RS232 and BMS/RS485

Thanks

The rs232 port is serial port for communicating with your inverter including reading and setting its parameters like Low Voltage and High Voltage disconnect (LVD and HVD), setting charging parameters etc. The BMS port is for communicating with the BMS of a lithium battery.

dollarnaira:

No modern inverter should behave this way, it only just stop supplying. Turn off / on business continues.

True, but some low life inverters will not shutdown gracefully, they will blow a few mosfets if overloaded. I wonder why?

mctfopt:


This is just basic economics, not like I'm selling anything. You don't expect people with old stock to suddenly drop the prices of goods bought at ₦1700/₦1900 simply because there is a ₦200 drop in the price of dollars.

But you expect them to sell old stocks at new dollar rates immediately it happens? Head, they win, tail we lose. God dey.

Dam5reey:


You are missing the point.. topic is about parallel connection, not communication..

You may be the one who missed the point. This was his question. "I know LiFePO4 can be paralleled but I wanted to know if there's provision(PORT) for his battery pack to be paralleled like using RJ Connector to parallel both batteries."

Note the bolded parts.

Dam5reey:


Not totally correct too,
Data communication does not make Good BMS...

So you cant parralle without Communication?

1. If your BMS does not come with the ability to communicate with your inverter and fellow BMS, it may be good, but not good enough. Premium BMSes on premium lithium batteries are able to communicate with each other to synchronize charging and discharging.

2. No, you don't need battery communications to parallel batteries, however, it is good to have. It makes your batteries work together better. For dumb lead acid batteries, there may not be any need, but for smart batteries with smart BMSes, communications between batteries make for better overall experience and health of the batteries.

3. Finally, if it is so useless, premium brands like BYD, Pylontech, Seplo etc will not put it on their systems.

Dam5reey:




What does RJ port have to do with Parallel, Does Solar panels or Batteries need RJ before they give you more AH or A when you parallel them?

When you Parallel a Batteries or Solar panel, you simply connect the + together and - Terminals together to give you combined AH or A.
If you do that for a 100AH and 105AH it becomes 205AH, if you do that on Solar panels of 8A and 10A it becomes 18A.

Not totally correct.

Just like inverters, lithium batteries with good bms can also have data communication such that all the batteries in parallel can work like one single giant battery. Some premium charge controllers like Outback and Midnite Solar also have this data sharing connection mode. However, unlike inverters, parallel communications are not compulsory for batteries and charge controllers, but premium ones do have them. I know that Pylontech batteries have such communication ports. The Felicity lithium also have battery to battery communication.

You can see the picture of pylontech battery to battery connection below.

isangjohnson:

Boss, even with large bank, lead acid battery can still be properly charged and managed very well.
Once you get the basic things right, every other thing takes care of itself.
This issue of comparing LA battery with the Lfp has been discussed extensively some years back in this forum.
George_D has large LA battery bank and he has used it for about 6 years then. Maybe, it's up to 10 years now.
He's one of the founder of this forum and I really learned from his knowledge and I'll always appreciate him.

I won't be surprised if George_D himself has cut over to lithium. With the current prices of Lead Acid vs Lithium, it probably doesn't make sense to build a large Lead Acid Bank. For those who are starting off with small load and few batteries, lead acid may be okay. But for large loads and large battery banks, Lithium is a no brainer.

feflo:

I'm so sorry for the delayed response, I sold some recently but I will check if it's still available and revert back.

Many thanks for your interest

Also interested if this is available.

Do you know that CBN has printed new Naira notes this year?

Yet finance minister blames the previous administration for printing too much Naira.

The pictures I attached are for the doubting Thomas.

The 1000 naira note I attached was withdrawn by me over the ATM.

If truly there is excess naira in circulation, why is the new administration printing more in less than a year in office?

You should stay out of this kind of discussion because you really don't know what it means to "print money". Paper currencies are printed regularly to replace destroyed ones. That is not the same thing as "printing money" as an economic manouvre. Google is your friend.

lacicrips:

Ok. Are batteries not replaceable anymore? Surface Go 1 replacement batteries are sold on ebay for $30-$50. Not that you deserve my response with that rude ignorant comment tho, but lucky you...

Like my people will say, "if farming is easy, why would someone chose to sell farm implements instead of farming"? Why don't you buy the battery and replace it yourself?

lacicrips:


Still available. Who's the lucky owner?

You mean who wants to buy trouble? A swollen battery is a fire hazard. Anyone will be a fool to buy this for use.

Drgreatone:

What happened to the smk? What was the setup like with it in terms of protective devices/panels seeing as its just the inverter that got bad and needs replacement from ur submission. That wud help in advising u further.

SMK inverters are bad. A friend bought two and the two had problems in months.

I bought the first one in November 2020, the second one is March 2023. The two are doing well.

I am looking at FELICITY 80A because it seem like the only one that supports me remotely controlling it. I dont like going to charge controllers to check the screen all the time. I prefer to monitor everything from my ohone. The new Felicity MPPT controller supports that and seem readily available in the Nigerian market. Whats your take on FELICITY charge controllers

Felicity Charge Controller crew here. I have 2 120A models in my house serving admirably.

Don't care.
Just don't say you purchased a new Nvidia shield Pro @ $100 at anytime. The official price from day zero has been $200, the $180 you see on Amazon is just a - 10% promo.

Okay, I didn't buy it, I stole it. You know, I just bought ONN Android TV box for $20. I'm sure that a few years down the line, you will say that I'm lying.

https://www.walmart.com/ip/onn-Google-TV-4K-Streaming-Box-New-2023-4K-UHD-resolution/2835618394

You know what, happy sale.

Ournolly:


I do not know the one you are using but there is no issue with the 2019 pro version.
You are obviously using the Nvidia Shield Tube and not the Nvidia Shield pro.
The tube version will lag on gaming because it's not optimized for gaming.
Also, Nvidia Tube is 2gbram/8gb rom while Shied Pro is 3gbram/16gb rom, even at that there was no time Shied Tube or Pro was sold @ $100 even in the Official store at Amazon. The Tube price has always been $150 while Pro store price @ $200. Adding all the fees in Amazon will be taking it to about $260. If they are currently selling at $180 it's likely a promo price. I prefer avoiding the Amazon fees and sales rejection wahala. Other alternatives like eBay etc work fine for me.

I used Xiami Box S and wasn't impressed a bit about the upscaling, after reading a lot of reviews on Nvidia Shield Pro I opted for it and wasn't disappointed. I ended up dashing it to my cousin Xiami Box S.
Google Tv with inbuilt Chromecast is a streaming box like Roku Tv. Most Smart TVs come with Chromecast inbuilt hence not necessary. There is nowhere you bring them near Nvidia Shield Tv.

I also do not know what the heck you mean by Shield TV 2019 coming to end of life. 2015 and 2017 versions are still being updated and supported. How then can the 2019 version be nearing the eol? There has been a rumour of new version for over 2 years now and yet the Official channel is yet to release any news of such.

The best about selling is that both seller and buyer have choices to make, I place mine at 100k and won't remove a dime from it.
You do not agree with the price you move on, commodities are sold by the value placed by the manufacturers and marketers. Buyers can only negotiate if they are allowed to or move on to the next.

I have the one you advertised. I can send you a picture if it interests you.

Ournolly:

My brother, it's annoying.
Most of them know the price and it's not even in Nigeria market.
I purchased it from Ebay @ $250, not including the cost of the shipping.

It doesn't matter how much you bought it, people will price it based on the value they put on it. While it is true that Shield is possibly the best android TV on the market today and it has been well supported with updates so far, it is not worth a 100k at this time. It is nearing end of life and I doubt if Nvidia will update it much further. In addition, Xiaomi Box S and Google TV with Chromecast are cheaper and are equally capable. The gaming on the shield is almost useless. My children do not use it for gaming despite the fact that I bought a game controller with it.

I can not pay more than 50k for Nvidia Shield at this time. I don't think it is worth more than that. Others may be able to pay a lot more if they value it for more. There was probably a time I would have paid 100k or more for it, but not now and not any more. By the way, I paid $100 for mine during an Amazon sale long time ago and it is currently $180 now on Amazon.
