Good evening house.
Any expert in the house that can assist with a quote for a solar setup with 100ah battery.
Inverter of 500w
Solar panel.
Setup will be used to power appliances not up to 100watts

You can make calls and compare their prices and visit their store to see what you want to buy or your visit alaba or any other close to you and see what you need

Thunderbolt:
Dear House,

Please I am trying to get true 250w or 350w solar panels (used or new).
Please could someone kindly advice me on how to go about it.

Since your battery is 24V lithium, that is what your charge controller sees, and your battery also being 3s or 4s at 12V (x2) for a 24V system

The main thing i see here is your solar panels, it is observed that panels with Trina solar slapped on them from Alaba, there is a 50/50 chance it is

1. Used panel sent over from abroad

2. It has dropped its power due to long time in service or as Dam5reey as said it is a 12V panel falsely labelled as 24V

In short there is no potential flow of power from your panels down to battery,

Try and series your panels together to achieve higher voltage as that should be able to charge your battery ... 50V or higher I guess is the Voc of your Controller so two in series should work with no problem

OkoroPeugeot:
The battery is Lithium so I think it only does the auto switching for Lead acid batteries and does not support 24v for Lithium .

I'd revert the connection to 12v and plan towards the MPPT.

Thanks so much!

Good morning and Happy holidays to all members of this forum, I personally want to thank those that believed in us and those that help us along the way

The year was plagued with a lot of up's and down's, from global pandemic to insecurity but we all still going strong

Happy holiday and a prosperous new year

From Me to you and our team at Rendezvous Solar

Thank you

I stay in an area with bad swift network ( little to no signal) only window works until I tried things out with this antenna

Now I have a stable one bar, and increase in internet speed of 100/200KB/s to 1.5MB/s

You should give it a try... Can work for your normal phone

Then you need to upgrade your panels to produce more power; attached is power production of a typical tier 2 panel

I don't know much about the batteries you listed but I am sure many others who use it can give a better insight

kaziem:
I am actually considering LiFePo4 of 24v 200Ah or 5kw capacity so I feel I am not undersizing.

Now talking about LiFePO4 with good BMS, this is why I need advice on good brands.

Good day guys we are organizing free virtual consultation for people who are

1. Having issues with their installation

2. Gathering information to decide if solar is right for them

3. Looking to upgrade their existing installation to better ones.

Kindly contact us via contact on signature

See this post by Rendezvous Solar on Google: https://posts.gle/c9Syie

Let's assume you
1. Plan to charge with grid and solar - your inverter will charge your battery at bulk/absorption but at float it won't make sense to charge with it being a pre-program parameters

Seek for an inverter with editable parameters or continue to use your inverter but never use grid to charge since you don't plan to monitor

2. Assuming your charge controller is editable, your panels is enough to charge your batteries without loads

3. Since your loads is unknown in your quote, it is safe to assume it abides by 50% DoD of your LA Batteries else you might undersize for the lithium battery too

4. LiFePO4 is a safer chemistry over Li-ion so there is little to zero chance of explosion while charging

5.if yoir battery is built with a good BMS then you only need to install and forget while focusing on productive activities

.

A correction to valto, the company gives a one year warranty

If well used, it is guaranteed to perform well for two years

oliyeniun:
Hello house, please is it true that this amarom quanta has 10years warranty because someone wants to sell this to a friend of mine and said it is even better than tubular.

This seems right up my alley, there is propsective project I am looking forward to and I hope to get four of this if quantity is available.

Still researching more but the info so far is looking promising

Dam5reey:
Seplos BMS 48V, 16s, 100A.. with comms.. Brand New...
85k negotiable
081323-944-78
Also 8s Daly 100A with Fan still available - 45K

Yes, I didn't because they are both produced by the same company and imported by simba group ... Though there are opinion that genus is better than luminous but I believe both are the same.

Hamthablow:
Good day bro, I notice you guys don't talk about Genus battery and inverter. Can you please say something about it.
Waiting to get a response.
Thank you.

Noted, but I believe you got the usage I was referring to wrongly

So between 8pm - 12am/3am -7am

How many hours does these appliances run for?

Saying that they all run for 8 hours mean they will have used 4,400Wh
Equal to 4 battery system theoretically

Kindly give a detail estimated breakdown hours of their running as stated above to give a precise advice

Yes, both NEPA and solar can charge alternative or as you plan or decide it to be.

Bbdealer:
God bless you for this reply

My usage is 8hrs (8pm to 12am and 3am to 7am)
Also can I charge the system with both nepa and solar alternative

For your loads, estimated at
10W bulb
85W TV
80W fan
20W decoders
Total of 550W , a 1KVA inverter can handle this loads

What is confusing is your pattern of usage isn't know meaning if you run these loads full time and inefficiently your energy storage (battery) will be huge
If you can state your usage pattern and let other folks look into it will be cool

Products you can look into
Battery
NXT index battery
Quanta Battery
Eastman

Inverter
Luminous
Eastman
Vmpower
Others

Solar panels
Jinko
Canadian
Yingli

SMS
Flames and others

You will need an MPPT charger for more efficiency of your battery charging

And others

Bbdealer:
Power load:
10 energy saving bulb
2 flat screen
3 celling fan
2 decoder
Please I need a total list of type of battery, solar panels and everything needed for a fully operational setup

Alright, I will be in touch

sethtsadopp:
I can see the prompt on nairaland but didn't see the email. Kindly email me on babatsadopp@gmail.com

You mean this is your operating loads day in, day out or your run them efficiently to make longer backup time?

guente02:
I'm using this to power my 2400watts(running) load. The load comprises of
1. 1.5hp Hisense Inverter AC
2. 1.5hp Copper Inverter AC
3. 32inch LG Desktop Monitor
4. 1 MBP Laptop
5. 1 8kg Hisense WM
6. 1 215L LG Fridge
7. 1 standing fan

In need of a LiFePO4 cell charger, not pack & please state the features

Please kindly reach out ASAP

In need fairly used 200Ah x 3 pieces for patch

Batteries must still be operating within 12.4V and above under operation or battery is subjected to tested with battery loader for health.

Please kindly quote or reach out to me via contact on signature

I have not encounter such error before and the error is not available in Growatt error handbook

What battery is used with the inverter?

You should mail growatt directly at service@ginverter.com

Or contact your seller for warranty claims

jamesid29:
Good morning house. Please has anyone ever encountered an " [color=#FF0000]Internal communication error[/color]" on a growatt inverter before.

The inverter is just giving a continuous ringing sound with an error code of 62. I checked the manual and it says that's an internal communication error.

Please o, anyone knows what caused the error and best fix for it. There's nothing on google and the manual so far. Pls any help or insight is highly appreciated o. Thank you very much in advance

The inverter is a growatt 5000es inverter.
Below is a short video of the issue as sent to me

To you access to the sea or a wave breaker to the sea around your area?

And what fishing gears do you have?

Kindly call me via DUO this evening 7:30pm let's talk for a meet up

babniyen:
I am in Lagos but on the Ftz area.. Thanks

Hi,

I will send you a DM via your Nairaland email, kindly respond.

sethtsadopp:
Greetings,
I was wondering if you have a picture catalog of some of your resent medium to large scale installs that I can check out on any platform or have it mailed to me if possible?

Cool

I work and stay in Lagos but move between Lagos, ibadan and ilorin

Is your axis down these lane?

babniyen:
Please count me in too.

Thank you sir

Daboomb:
That is a job well-done.
You seem to have an eye for details and that is a good thing for an RE Installer.
Keep it Up Sir.

What's your location?

It will be splendid to have a fish together

newinventions:
Finally, I have found people who share my interest. I am very much interested in fishing. The last I went fishing was when I was 7 year old or there about.

Would love to use the hand throw fishing net though.

Thanks for the compliment

Valto:
^^^ nice job @olopan. my epever 5kw hybrid consumes about 40w to 50w. the kartel consuming 240w is still a big waste. he should work towards replacing it with a something like this rugged TBB power inverter that has incredible low self consumption of around 17w to 22w

Sometime recently a member @En0uwem of this forum had a problem with his solar setup not charging well and not serving him as expected, he reached out to perform audit at his site

It was discovered his Kartel inverter consumed up to 240W while inverting and his base loads were hovering between 700-800W, from calculations it is noted that his daily usage had taken the energy generated by the panels leaving him with little energy by days end.

We were able to
1. Add extra panels to allow for more charge time and load provision via self consumption
2. Allow increased airflow and optimised the solar panel angles
3. Arrange the DC terminals to charge and discharge equally
4. Protect the setup against surge arising from lightning
5. Introduced OCPD and a means of shutdown in cases of fault or mainteance

Now the setup has seen improved charge time and usage

our Team will like to thank you for the hospitality and attention given to us while with you.

Evenly maybe!
since you will change it over only one bank is full

I would prefer you charge each bank with the separate solar array this way you only apply the change over on the inverter side alone

samnaija:
Thanks for this the knife change over, will it charge both banks evenly.

Yes a battery switch helps

Assuming that the array you want to use is big enough to charge both batteries

Getting a knife edge change over with the batteries being the two input and the output being the charge controller

Just don't change it over so quickly

samnaija:
The question is I want to charge the two banks with one single array. I know I can't parallel the 2banks because of age,does a battery switch help in this aspect to charge the 2 banks. Or any automated system for this thanks in advance.

Good afternoon everyone,

Please anyone with a faulty axpert VMIII, a friend wants to buy and try out the display to work with his lithium battery.

Kindly reach out please

You have managed your setup quite very well

BTW your battery just enters absorption at said time and on days where you didn't use so much power from your battery, you should notice the battery resting at around 13.7V or 13.x depending on your charge controllers setting

Polaris1:
My battery will float charge (14.2) around 10a.m on normal days, in the evening around 5p.m it's 12.7v. After powering only the fan overnight, it will read 12.5v.
I have been happy since.

Running it continuously for six hours is not advised, two-three hours at a go is Okay, especially for longevity and to do its worth or performance

With more power from the solar panel, the fluctuation of voltage will not matter, as your load is covered

Polaris1:
Will such pump run for 6 continuous hours 5days a week?
Does the fluctuating voltage that solar panels provide affects it's efficiency?
Thanks again.
