Deriy only have 280AH 12.8V 3.6kwh you can reach us..

Seun:
I'm looking for an all-in-one with at least 5-8kw inverter and 15-20kwh battery. What do you guys recommend?

My Sako inverter has been displaying two error codes today.

Error 51 (overcurrent or surge)

Error 58 (Output voltage is too low)

The persistent one is error 58, nothing is coming on.

I've disconnected all inputs and outputs, as well as the battery. It's still the same thing.

What could possibly be wrong?

RickyM:
Thanks for the suggestion…I eventually nailed him, his house is just opposite the pharmacy I figured out.
I got my money back too!

Its been quite a while since I've come on this thread, but a certain video jumped into my feed and I couldn't help but smile that my Solar community would love this soon to be roforofo fight between two well known "solar influencers"

I am only going to post one of their videos on this thread seeing as it summarises what the whole fight is about and if people have really been paying attention to the free interactive university that is this thread, you will see who is erring ( more than the other party) and repeating it with gusto.......

Experienced gurus, please lie back and let the newbies take a shot at finding what is glaringly wrong before adding your own tuppence oooooo... abeg

Video has been taken down or is private.

FEGEITOK:
I was fortunate to watch it before it was taken down.

I will share something on the video later today

dollarnaira:
@Fegeitok and androblaze what is the video all about? Video is no longer available.

tziz:
Hw much pls?

FEGEITOK:
Based on popular request and demand

AndroBlaze:

Lol, can you imagine.

A Solar "guru" with over 23k subscribers uploaded a video at 1am and before 5am he has rushed to take it down after standing on principle that what was witnessed was impossible....lol lol.



Chief to put some context I have posted the link for the original video he reacted too.

Apparently DIY with Ray had long ago (over 2 months now) posted a video of a capacity test for a 10kwh (51.2v 200ah, 10.23kwh) lvtopsun battery where he got pretty impressive results of 10.53kwh discharging over 206ah in roughly over 2hrs.

Smilinsun Solar Energies claimed that people had inundated him with requests asking if he recommends the battery and if that capacity test was possible.

He basically tore into Ray, claiming the test was too suspicious and the results absolutely impossible, without him doing unhealthy things like bypassing the BMS and pretty much faking it.

His argument was centered around DOD. He claimed you are not suppose to discharge a LIFEPO battery to more than 90% DOD and even went ahead posting another video with LVTOPSUN representatives in Nigeria where they also said their battery won't do more than 90% DOD and they guaranteed 6000 cycles.

Now you may ask, that all this seems sound so far..... well it is. But then with all the English he speaks and wonderful carriage he has (compared to Ray oo, at least from the outside), he now came in with his claim that 90% DOD on a 10kwh battery cannot be more than 9kwh!!

He claimed that since LVTOPSUN stated the battery was a 10.23kwh battery, there should be no way it could be discharged healthily to 10.5kwh. He repeated this over and over again insisting the BMS should have shut it down and no 10kwh battery can do 9kwh (awon Felicity brainwashed people), all this on the DC side ooo.

At the end of the video he claimed he'd rerun his capacity test on the battery, making sure he buys a retail unit in case LVTOPSUN had fixed it themselves.

Now, my shock was that this man with over 300 videos and 23k subscribers coud make such an elementary mistake when calculating DOD....as even in the days of lead acid, you cannot calculate DOD based on the metric he used.

Basically DOD (with all the chemistries I am aware of) should be calculated with VOLTAGE and not based on POWER, let alone amperage.

Most agree that 90% DOD on a lithium cell hits @ 3v a cell (12v for 12v batt, 48v for 48v batt) and practically every BMS will cut off way before 2.65v a cell. So LVTOPSUN did not mislead nor lie with their claim.

If he understood this, he would have focused on other things he could have used justifiably question Ray's results in my opinion, like how the battery got such great results being discharged in only 2hrs at such a high C rate (though Damreey has just done the something similar above from what I can see) and if LVTOPSUN sent Ray an overspeced battery knowing he'd do a capacity test.

Anyway, this is why I laud this thread, it's contributors and community as a whole for being a reservoir of great knowledge (both practical and theory), as even though one can be away for months or years, the discussions we've had here ( usually from proper life experiences) would have enriched you with so much knowledge that it honestly feels like you have earned a proper degree in this area.

Enjoy Ray's video, and I actually like the guy a lot as he's pretty practical and just goes straight to the point.

Mr Seun of nairaland....... 🙌🙌🙌. Hope u get to also see our member's complaints abt the bot here and save this page.
About ur question, it’s better and advisable u get seperate systems ie inverter and battery than going for an all in one. Ease of expansion is key here

casualobserver:
i have seen a lot of his videos. the guy is learning on the job. some of the things he says are correct but he makes out like he is more knowledgeable than he really is. There are many things I have seen him say in his videos that are outrightly false.

to me he is a cowboy. I see him as someone who could have studied a non technical subject like history or economics but developed an interest in Solar and turned it into a business but lacks basic technical knowledge.

verify anything you hear from his videos. personally i dont watch his videos anymore.

casualobserver:
I don’t have to watch the video to know. He’s had it coming. I’ve never seen such arrogant quackery in the Solar world.

Smilinsun is a cowboy a quack, I’ve said it long time ago. The annoying thing about him is there is nothing worse than someone with half knowledge who refuses to learn or be corrected and Carries on as if he knows it all. Worse still is he insults or questions anyone who questions him or if he cannot explain a situation because of his limited understanding or knowledge he attacks the installer or the product.

I only pity those who patronize him or watch his videos.

I said it long time ago:

Yes chief, I remember this your last quote then, you did say so and called it right.

PS: I studied History and Economics , abeg take it easy on us in future, our book no "plenty" so we haven't lost the ability to develop new interests , joorr ooo
