Valto: buy a single burner toks halogen electric cooker(consumes max 1600w), minimise other house loads when using the cooker. your inverter can comfortably carry load lesser than 3kw..cheers.
Do not try this so called halogen cooker, instead just go for a recent or for foreign used induction cooker with low watts another benefit is that the consumption rate can be adjusted
HeavenlyBang: I've recently realized that I need to restart my inverter every couple of months for best performance. Otherwise the MPPT just starts doing whatever it wants (sometimes charging the battery at really low currents and only drawing more power from PVs when I add load).
It's ultimately a computer so that's not surprising. Rebooting is the first solution in IT troubleshooting.
To reboot I turn off pv input and shut down the battery, leave for a few minutes, then turn on battery and PV. I've had to do that a couple of times in the last ~15 months and seems to fix any issues.
From my experience it is the breaker from Pv that is causing it, so try that solution first.
officialfestus: na Valto make me never try any lifepo4 build, because he no they respond to my messages. Abi na crime to inquire about prices before I make purchase?
All the time I done message am he replied me oh almost immediately self. I saw e even has the lifep04 that’s why I mentioned it earlier.
CaptainArc: I'm about purchasing an 80kmah DC powerbank from wiremind, can someone recommend a 100w solar panel that can charge it from zero to full assuming peak sunlight of 4 hours daily, (brand new or used)
It depends on two things… 1. The way they were made and 2. The way it is been charged and discharged Some type of cells/ brand are quick to react to issues by Bursting into flames or gasing out
Machiny: want to buy. Asking if the fan is loud, firman was my first choice but all purchase is online from ph, weighing my options. Are you using bread? If yes what's the fan sound like?
I have SMS the fan is not that loud like someone said it could be individual difference I started paying attention when I read some people here always talking about the fan. So mine could be loud but seems normal to me( individual difference) 😆
durodee: The Yohako inverter I have uses 12345. My experience is that quite a number of Chinese electronics use easy to remember default passwords. Try 0000 or 1111 erc
The problem is that it doesn’t even show the numbers so I can input, if I press down or up arrow key it shows I’m imputing something but I can’t see what going in nor do I know what I am pressing, it just shows asterisk blind figures so I don’t know what’s going in
Please does anyone know about this controller. I want to change the battery setting parameters but it has a password. I already asked the person who sold it he has no ideal about the password. It will work very well with acid batteries but now I have lithium. Your input is appreciated.
Is there still any motivation to build 18650packs when it seems the price is already been rivaled by new LFP, factory made packs?
Tetralogyfallot...how much are your cells going for? To help give context to my question.
Lfp are becoming cheap and it makes no sense anymore building huge packs of 18650, when at the end of the day new unused lfp is cheaper, except you are building small projects then I recommend 18650
I hope you still remember me and the wahala I had after being defrauded and given a 2.5Kwh Sako lithium battery instead of a 5Kwh battery which I paid for.
GOOD NEWS: I’ve gotten my brand new 5Kwh battery.
Sako CEO got involved in the matter and promised me a new battery once their container comes back. She fulfilled her promise and I collected the battery yesterday. I must say that the customer service I received from Sako was premium and top notch.
The agent who defrauded me still tried every possible means to stop the company from giving me the battery. It was full blown war. He cooked up many lies and stories and tried to make the company believe that I and my technician are the fraud but the company looked through the whole smoke and saw the truth and gave me what I paid for. SAKO has won my heart shaa and I’ll advice anybody buying from them to go directly to the company. I have their direct link if anybody needs that though.
I want to specially thank everyone here who took their time and wealth of wisdom and experience to advise me on how to go about the stuff. Your advises paid off and I don't take it for granted. Thank you sooooooo much and God bless you all. May people that matter rise up and help you when you need them.
I also want to specially thank @Androblaze and @Dam5reey for the roles they played. @Androblaze took it upon himself to help me. We chatted and talked for long on WhatsApp on the way forward. He was always reaching out to know how far and to advise on the way forward. What a man! This issue taught me a lot and also made me believe more in humanity again. I stopped posting here since as I was advised to stop as my enemy might be reading my strategies from here too. @Androblaze, my brother, thank you sooo much and God bless you and raise people to help you when you need them.
Below is the picture of the new battery. It is way heavier and bigger than the first one.
Sincerely, I thank God that I met this beautiful community of people willing to help each other achieve Solar energy independence. I've learnt a lot here and I keep learning. THANK YOU PLENTY!
barezy: Am building my self the biggest battery I ever build, am planning of adding 6pcs battery to each parallel, I will surely do that before I finish the setup.
I build this cells very well with welding tools but now I don’t advice people building such large battery with 18650 cells anymore, lifepo4 can accommodate very few cells and are becoming cheaper. No body is above mistakes so to avoid catastrophic situations in assembling so many cells that are dangerous. Just an advise though
Hahahahah you carry the most expensive tubular against the one of the cheapest lithium battery even at that you can’t be draining your tubular battery like that soon or later it’s dead 😵 for me lithium tech is still better my car brand has even moved from lithium to sodium ion, men forget it there is no going back
Enyinne: I bought it and I'm regretting it even though I got it from their accredited store .Fake too much .it doesn't work with half current while my Samsung inverter works perfectly on low current.
Because its inverter doesn’t mean it will compulsorily work with low voltage ok. You should have looked at the power rating before buying it. That is always the same with inverter AC. Not all likes low voltage look at the side or back you will see the voltage requirement
dollarnaira: If the cells are not laptop extracted, I see no reason why it should work at a huge 7s. It goes beyond how he soldered. He could even spot weld but used a poor of fake strip.
I have 288 cells at 3s all soldered for a reason but powered 0.5h sumo without blinking.
Yes we can’t overrule that fact, poor soldering or welding can lead to multiple open/disconnected joinings that’s possible what happened
Intellab: I had some challenges with my previous 18650 battery setup. I used 644 cells configured as 92P7S, but it couldn't power my 1HP Sumo pump effectively.
So, I upgraded to 314Ah LiFePO4 batteries — 8 pieces in total, giving me around 8kWh of usable energy. I built the pack using a JK Bluetooth BMS with a 1A active balancer, 4*250w solar panels, felicity MPPT. Batteries and the BMS were sourced from Valto.
I also switched to a 0.5HP Sumo pump, and now I have 24-hour power supply. The Sumo, washing machine and a lot runs smoothly — everything is up and running without issues 24/7.
Probably you did something wrong or the cells where already losing there capacity, 644 cells that huge bro, maybe you used soldering iron to degrade their capacity while assembling it.
chris81964: LIGHTNING STRIKES... BUT MY INVERTER STOOD ITS GROUND! 🔥⚡
Do you remember that video I posted about how lightning can shut down even the best inverters? Well, let me take you behind the scenes of what just happened — and trust me, this was not your average rainstorm.
It started with a LinkedIn post I read some time ago — multiple inverters within a 5 km radius had failed after a ferocious lightning storm. These were properly installed systems, with earthing and SPDs in place — yet they still failed. That got me thinking. That got me experimenting. That got me ready.
Then yesterday happened.
The heavens opened. The sky lit up like a thousand fireworks. This wasn’t just lightning — this was lightning on steroids. Strike after strike. Some so violent they triggered car alarms in the neighborhood. The whole area was under siege from Mother Nature herself.
And there I was… watching… waiting… monitoring my system.
GUESS WHAT?
Not a blink. Not a flicker. The lights held steady. My inverter stood its ground like a warrior. My solution worked. The theory became fact — and it survived a full-scale attack.
Whew. That was intense.
👉 Watch the full video to see how I solved a problem that takes down systems worth millions. If you care about your investment, you NEED to see this.
