Bravo..

I am yet to visit the site, but I asked the client for a screenshot while it's charging this morning and requested for another screenshot when it stopped charging at noon.

I never knew 3.35v is the float voltage, so BMS calibration has 3.45v as 100% indicator, so that's why it stopped charging at 88% yet the average cell there is 3.365.

So I am requesting for his shinephone login so I can adjust the growatt parameters accordingly. Hopefully that will settle the 38% complain also.

Thank you, thank you, thank you everyone for your contributions.

I read later where you said your cells are well balanced.

Two possibilites;

Either your BMS parameters were set too conservative for the charge parameters you want to use OR your cells exhibit a larger voltage drift than you have noted under charge or discharge with high currents.

Do you have access to your BMS protection parameters and can you publish/screenshot them here?

When the BMS cuts off charge/discharge, what error message is logged?

In any case you want far more conservative charge settings on your inverter 55.4v absorb and 53.6v float.

The above settings are 3.46v per cell and 3.35v per cell for absorb and float respectively - at a 3.35v per cell float you can be sure no extra current is making it into the cell and no possibility of overcharging it even over the long run.

Observe the battery pack voltage delta (mV difference between highest and lowest cell as well as highest cell voltage) when the inverter is in absorb and also whatever error message is logged when the BMS cuts off power - these will clue you in what is going on and where to direct your efforts.

I have a 6months used Growatt SPF 5000 ES for sale. Still under warranty, used personally and in mint condition with USB monitoring dongle.

Thank you in advance for your help.

@tsiriman :: thanks for your input, suggestion noted

@earthrealm :: noted, I'll try that.

@Jefferyzz :: no, I haven't tried external charger.

@NiyiOmoIyunade :: I will have to make a trip to the client's house this weekend to get the screenshot of the set parameters. Usually, when the BMS cuts off, there is no error message, maybe I will tell the client to be more observant. For the suggested voltage settings on the inverter, I will try that as well.

@Dam5reey noted sir.

Thank you to everyone for your contribution, I hope to be back with a positive result.

I need help here please.
I use a Growatt SPF 5000 ES,
Connected to 16s DIY LFP cells
And 16s 200a ANT BMS

At first, I set my charging voltage to 3.6 X 16 = 57.6v, float voltage to 3.5 X 16 = 56.0v,
but after so much information gathering here and there, I settled for 56.0v as charging voltage and 55.2v as float voltage.

But irrespective of the times I made the changes above, I am always having problems with the BMS. Sometimes it charges to 90% and stops charging, other times 38%, 68%, but if I reset the BMS, it will continue charging and eventually reach 100%.

This is now beginning to happen on daily basis, but before I go ahead and change the BMS to JBD, I want to be sure what could wrong please? I have sold the system to a client after few months use and I am beginning to look like a bad man now, energy initiates come to my rescue abeg

Ok, noted, but then that doesn't mean it should stop charging at 38% when it's barely 53v yet

@saint2ace, you are right but the cells are balanced
Highest being 3.29 and lowest being
3.288

Valto:
56v a little bit too high, set the charging voltage to bulk 55.2v or 54.4v
float 54v or 54.2v

Accurate response.
I wanted to give my input earlier when the post was made but I do not want to look sentimental because I just advertised a front loader.

That's the best type of washing machine you can use both for your business and domestically. It consumes less water compared to top loader. And if you buy the LG inverter models, they are direct drive motor unlike the Hisense which uses a belt to drive the motor, hence require maintenance often. There are more expensive brands than LG but if LG on the average does the job, what more do you want? And sweet thing is, it's very noiseless when installed properly.

GloriousGbola:
You are honestly asking the wrong people here imho. Most of us here are domestic users looking for deals on items for home use.

Middle class and below buy top loader becaue 1 it does not need to be connected to water supply - you can literally pour water in from a bucket
Same way you can drain it into a basin.

Rich people buy automatic front loader. This has to be properly installed and connected to your water supply and drainage. In addition, if I am not mistaken, it has a heater which means you will run it on nepa or big gen. Can't say if the heater is a must use.

But most of the commercial laundries I have visited use front loaders.

You are better off doing research or googling Nigerian laundries. Then you can do your 'customer' survey and see what works for them. Or even ask the workers

Not awooof!!!
But definitely the best price you can get.

I bought this washing machine last year August and didn't install until September. Bought #370,000.

mangolpupa:
Experienced folks in the house, i have a 1.8kwh agm battery (12v) x 6.

From the information gathered, I need a 5kw hybrid system (i have not made up my mind yet, but considering felicity hybrid, sorotec, growatt for now). the inverter are detailed as 48v. Does it mean that the battery will have to configured to output 48v (?s?p) in other to function.

What are the implications of this configuration and inverter spec on feature solar panel purchase.

Thanks for sharing your experience
How many batteries are you using connected together?
What's your max charging current?
How often do your water needs topping?

Namzy:
I've been using mine for 4 years. Just don't discharge below 50% and I'm sure you can get 8 years easy

House abeg o!!!

I have been hearing this often and often, from your experiences here, do the tubular batteries in our markets here really last 5-8years for real?

My cousin studied microbiology, can he still get a school for May 2023?

Ok sir.
Thank you for the clarification.
I appreciate.
Good work you're doing out there.

Abolarin91:
If all strands spark it means all strands are connected.
On the whole 6lines, some are earth, some are out and some are in. Thereforethey cannotgive you thesame volt or amp.

Yes I did just that now.
It sparked intermittently.
Why I thought so was because my faultfinder equipment showed

9.5kv 0a on 3 lines
And the remaining 3 lines 0.5kv 2a

What does this mean please?

Abolarin91:
Good day sir...
All the wire(either 6lines or 8lines) must be shocking.

Get a cable(covered with insulator), open both end, hold the insulated part of the cable and use each end to touch different wire on the fence at the same time. You will feel the spark.

Give me feedback.

Hello sir, keep up the good work.

I have an existing electric fence wire installed in my house. Recently out of curiosity, I made some research on it, wanted to know if it shocks truly and not just the alarming. So I bought a device by JVA labeled "fault finder" and I discovered few confusing discoveries and the answer my installer gave to me isn't satisfactory.

My fence wire isn't shocking, rather it's the earth wire among the lines that shocks.

Is that how it's supposed to be please?
I suppose all the wires are meant to shock

Can you clarify that please?

Yes, panel is installed in correct position, I understand what you meant by people installing wrongly, I've seen numerous ones too.

I will take the pictures by end of today.
The 2 lights in question here doesn't have motion detection sadly!

earthrealm:
Hope the panels on the street light are inclined horizontally, not vertically, or near vertically?..i see a lot of people ignorantly installing the panels vertically....thats wrong.

2ndly can you post the specs of the unit, say bulb wattage and battery capacity?..u may have to open it up to get battery capacity if it isnt written on the body

3rdly, hope you are running them in motion dectector setting?....ie they run dim till they sense movement..then they activate full brightness till the motion causing body has left the are

Please house, can you review solar floodlights and streetlights? I have had and still having horrible experiences with them. I bought over 25 of keye streetlights and floodlights last year, they didn't survive 6months of good brightness before they all went bad, I returned just 3 to their office last week to rectify based on warranty, they replaced the battery in 2 of them, I charged for 48hours then use one night it worked fine, then next night 5w led bulb is brighter than it as I write, though I learnt my lessons late, it appears that nothing I ever bought from Keye ends up good. Also, this SMS Black 300w floodlight with 2 panels, when I check outside my house at 2am, they are all gone and they are barely one year as well. I'm about to give up and want to revert to conventional lighting from my house AC power but it would be wise to know of other people's experience here too. Thank you

I've always been a fan of net zero homes and living totally off grid.
I am not rich, so in every ways I can cut future costs and reduce bills, I don't hesitate.

The power supply in the area is very OK, no issues at all.

Asking price #30million.
With the properties in it, #40million.

You can make a down payment of 50% and spread the remaining payment over 12months. I am relocating from the country, hence reason for selling.

Anyone in Worcester? Who's going to University of Worcester?

I just got a conditional offer from them 2hours ago

Good evening house,

I got a conditional offer from University of Worcester barely 2hours ago, requesting for deposit of 7200 which is 50% of the tuition 14,400.
With a deadline to pay on or before 7 November, that's just 7 days from now.
What do y'all think? is it worth pursuing?
Only way payment can be made is to go through black market and 7200 is massive for the moment.
I hope they are not one of the schools that will tell you no more space for January intake after one has taken loan to make the deposit.
Please, I just need some sorts of encouragement with an icing of truth .
