Brotherman, it's best you have an adequate surge protection in place, get some DC SPDs and connect it to the earth of the building, that saves you from any guess work.

I'll post pictures of low cost but effective SPD that one can connect without any technical skills. But pls let's protect our little investment. Naija no dey smile

It's very obvious you didn't read my post before making this comment. In Ur haste to comment and sell Ur goods, you didn't do ur due diligence before making Ur comments public, cos if you had, you would have found out that your product was the first link I shared with her on the post you quoted.

While I appreciate Ur doggedness at making sales, I would advise you refrain from calling out people without due cause. Cheers

I really appreciate your response. Thank you!

I need to mention that I stopped using the inverter and battery as soon as it stopped charging, I worked from a friend's place whenever there's no power till I got the battery charger, neither did I ever use it when it's low. You need to see how I pamper it cos it's important to my job. As soon as it beeps once I turn it off immediately! and the beeping sound only started happening when I started charging with an external battery charger and this is because it doesn't last beyond 2 hours.

So it's most likely number 1, the guy installed a fake Chinese battery without warranty for me and failed to let me know. Funny enough I got to know him from nairaland here!

Please can the battery still be redeemed, if yes, please let me know how to go about it, if not, kindly tell me more about the laptop battery bank as I haven't heard of it before. If I knew about it before I wouldn't have gone for the inverter honestly. The information I'd like to know is: How much should I budget for the laptop battery bank if I have to go for it, and what quality should I look out for to forestall any issues in future.

From my experience, you battery is gone, lead acid especially cheap Chinese brands cannot be saved, you might have a slim chance if it were the premium brands.

As for the laptop power banks, there are various models and capacities out there mostly based on your budget, from brand new ready made to locally fabricated.

On nairaland you can look at offerings from the following:-

https://www.nairaland.com/390522/solar-energy-complement-fta/1431#124263369

https://www.nairaland.com/390522/solar-energy-complement-fta/1433#124327564

https://www.nairaland.com/6808693/super-laptop-powerbank-extended-runtime

https://www.nairaland.com/7566401/solar-inverters-cost-implication-durability/1#120873962

https://www.nairaland.com/7542130/pastor-sam-adeyemi-wife-return#120398591

https://www.nairaland.com/7527435/know-there-powerbank-laptops-more#120087971

The list above were just randomly selected from their posts on nairaland, I can only vouch for the first 4, while others were selected to give options.

Lastly, if cost becomes an issue, you can simply swap out your existing battery and get a new one, there are premium lead acid batteries available in the market ( Fullriver and quanta Amarin) or off you can afford it contact @valto to build you a small lithium battery pack, that will last you a guaranteed 5yrs and more.

Hello here. Please I really need some help here.

I installed this inverter and battery in November last year for my remote job. I didn't install solar panels because we normally have up to 18 hours power supply in my area except on some bad days when power could go off for 2 days or more.

I use it to power just my work laptop and phone and it normally stay up to 2days or more before draining out. I work 9-5. I don't use it to power any other electronics, not even my bulbs.

All of a sudden in April, the battery stopped charging, when I informed the guy who fixed it I was told the inverter is bad, that high current led to it, even though we didn't experience any high current situation in my area during that time. He said I'll need to buy an external battery charger which I bought and have been using.

Problem is, since I started charging with the external charger the battery no longer last beyond 2 hours before it drains out and this is really affecting my job.

I have informed the guy who installed it but he's not proferring any solution.

Please I need help on what to do to get it to last 2 days+ as it used to as this is affecting my job badly.

I hate to be the bearer of bad news but your battery is dead. Haven gotten that out of the way, let's look at the reason why?

1. Your battery is a fake Chinese battery, so the internals are crappy. Even under optimal condition it wouldn't have lasted 1year.
2. Constantly draining Ur battery below 50% deep of discharge will kill Ur battery in no time, as the battery cannot tolerate the abuse. These singular reason is why the world is going lithium.
3. Ur inverter is one of the worst in the market as it can drain your battery to below 11v cos one cannot edit the parameters to a desired set point especially for low voltage disconnect, and if done a couple of times will put ur battery in a coma and the effect might be irreversible.
4. While I applaud your journey so far, not minding the setbacks, there is a saying that one's system is as good as the materials we use for it, quality hardwares aren't cheap so you might spend a little more to get Ur desired results.
Lastly and as an advise, since u're only charging Ur laptop and phones, getting a full inverter system isn't efficient as there are individuals here on nairaland who build laptop battery banks with lithium batteries for such task and these are more efficient and durable than the system u have.
I would advise you search for such and enjoy ur investment.
Once again sorry for the stress. Cheers

billyG:
What of d 1st question
I thought 12v battery needs 12v rated charging devices(12vbattery charger,12vsolar panels) PLS explain.

With the right charge controller, it doesn't matter the panels you use in as much as it is within the VOC of the charge controller it should work flawlessly.
Just invest in a good controller and the rest is history.

It's funny I only hear of 12v and 24v panel discussions on nairaland, seems the world has left us behind.

I HAVE DONE BUSINESS WITH ANUOREANGEL AND I CAN SAY IT ANYDAY ANYTIME, SHE IS NO SCAMMER 100%
She may not be the best when it comes to responding to chats but that does not make her a scammer.

Business can go wrong but banking on "She must tender an apology online" to defame her personality is totally unacceptable.

The truth is I personally started paying close attention to this thread because of sellers like her and @futurefocus.

This matter should be quashed by both parties, let us move on once and for all.

@Seun please come into this matter before they derail a very interesting thread.

Thank you.

Though I might not like the line towed by people here, but the core of the matter is that she needs to defend herself.

You made a comment that "the matter should be quashed by both parties", unfortunately I only see one party talking, so where's the other?

I stay in the same locality with the said seller but immediately I mentioned pickup of a particular set of sneakers, she stopped responding to my messages. I just left her and moved on.

If u have her personal contact as you say you do, why not contact her to come clear her name. Just my 2kobo. Cheers........

SOLD....

Take it to Idioro Mushin they'll fix it there...

Valto:

Reach out to Idyllic Technologies Limited for their range of fullriver batteries, they always honour their warranty.

Joshkid:
I've been trying to update my RN9S manually and I've been getting this particular error message everytime,

Updates are incremental and must be followed in sequence, you must get the exact update after version 12.0.3. I also noticed that most people who didn't update as at when 12.0.3 was released, that they couldn't update afterward, so the only option then was to unlock bootloader and flash a more recent firmware, I might be wrong but I don't think that has changed, I stand to be corrected.

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

Check your individual cell parameters and confirm that they are equivalent to the total pack set parameters as cell parameters over-rides pack parameters.

Lastly, use settings as provided by @Valto

The day I stopped all these custom rom flashing was the day I found peace.
It got to a point I could no longer use Firstbank mobile app cos I have exceeded the device limit, I went to the bank and the customer care agent was shocked, he said I changed devices 69 times.
He didn't know it's not a change of device but flashing several roms.

Jesu.... Thank God I no do reach that level. Flashing 69 times?, I salute you my oga

olayinkajnr:
Lmao!!!! Your reply to him didn't even age well self. Custom ROM flashing ehnnn.

Every traveller must surely come home. Even when such devices no longer have support, the default ROM is always best, but I can be wrong oh

hello, can I take 4 of the batteries for 120k?

Good morning boss mi, am selling off the whole pack at a time and the best price is 35k per unit totalling 280k

NiyiOmoIyunade:
Dear Boss,

In our private backchannel thread, this same matter has come up for discussion with other users sharing similar experiences

The ones marked pass are the ones I have found to go the distance. The more complex ones with multiple pages of functions including delay and recovery settings and notably a voltage calibration function easily go off kilter and become unreliable.

See pics below - first one is a pass - the others not so

Thanks My Oga for your response. While I might be knowledgeable about our back end discuss, folks here who have read your write up might not be so lucky, the question was aimed at enlightenment and also at providing information to those who might want to thread the path of purchasing the said item but do not possess the right information.

Once again thanks for the info and do have a great season.

Cheers

NiyiOmoIyunade:
Without raining on anyone's parade, those particular models - Tomzn branded - tend to be very failure prone - the ones with complex functions numbered from 1 to 13 or so.

Meanwhile the older gen ones with just 3 - 5 menu screens/functions were rock solid reliable.

Some people may have or have had a better experience with them than I did

Can u share pictures and specs of models that has worked for you, links will be highly appreciated...
