Yup and basically less/same price to that of a 200Ah lead acid, yet this will give better performance. Isn't that a good deal

Link to the seller pls.

Dam5reey:
It will keep the System balanced, as main goal, then inverter will handle protection

I learnt from people experience on YouTube

Could you share the youtube reference so I can learn how the BMS will effectively function without getting in between the inverter and the battery

I will check, maybe I watched too much nonsense

queenfav:
it has never beeped battery low,talkess of going off.The lowest i have seen it go is 23.3v

Fair usage then... I dnt use my 12v systems below 12.5v on the average.

queenfav:
lolz..he has to bring out the money biko.I have seen it firsthand that in order to enjoy solar energy, you can't afford to be stingy.

Topmaike007:
yeah you get it, that guy na my tutor from dummie to pro, God bless him for me

Yeah... I like him very much. He is smart, dexterous and is making some good money from his YT and affiliate marketing stuff.

BetaTechnicians:
Has anyone here come across/used 250w Flames solar panels ?

It’s 270w and not 250w sir

360w flame solar panel available, #40000. Call/WhatsApp us on 08168986461

5w DC bulbs available, #400 each. Call/WhatsApp us on 08168986461

275w lionstar mono solar panel available, #29000. Call/WhatsApp us on 08168986461

Bought mine 135k. Fyi it not my topmost hybrid, but it's what I use for now and it serves

Where did you get this one?, I'm interested as it is the same price...
Hope they have the same programmable settings.

If your inverter has LVD, set to 24.4V, anything below 24V will shorten the life of those batteries..

House is there anyone selling or can direct me on getting (d.c heating) element for water heaters .will appreciate thanks.

You can check the felicity Nigeria website contact as you may get it cheaper there, else PM for the contact I got mine from. As to settings, well they are all clones hence should have similar features. One thing though, it does not have eq which I guess you don't need anyway, since you are using Lifepo4.

What's it's surge capacity?
The 27V DC output, does that mean it can't charge batteries above 27V ?

justcallmenuel:

Ok, thanks sir.
That means the 250w being talked about here a while ago must have been a clone.

2* rated capacity and yes to the vdc question

Are there 24v inverters that allow you to set LVD above 24v? Especially the hybrids

Trippledots:
Yeah... I like him very much. He is smart, dexterous and is making some good money from his YT and affiliate marketing stuff.

He's a perfectionist also, I like perfectionists. They ensure there are no loose ends and do the utmost to give information that are verifiable and actually works not just paper specs and things someone said.

I do watch his videos, and other great DIYers on YT

ojeysky:

That's some limitation, 27Vdc is 13.5 each, that's just float or even lesser for some batteries.
Did you ever use it with your lead acid before going lithium?

Actually the voltage goes beyond 27v charging with my solar, i have not really tested the AC charge as am off-grid. In my case I use 28.2/27.2 for bulk/float respectively and no I have only used it for lithium but I know someone who use it for lead acid

Anyone

So had a dying powerbank/car jumpstart.
Decided to open it up..
Who knows what type of battery those are and if replacements /repair are easy..

3ndly, anybody has >330w canadian solar panels.
Could the person gimme the dimensions, need it for something urgent

Trippledots:
Yeah... I like him very much. He is smart, dexterous and is making some good money from his YT and affiliate marketing stuff.

yeah try and join that forum and meet cool friends around the globe

ojeysky:

Yeah, That's true, limit is 24V, it's fair enough for Lead acid, even for LifePO4, that is 3V per cell.

Thanks for the response.
Can you also set the maximum current for charging?
is the inbuilt CC a MPPT or PWM ?

Yes you can, it's MPPT

Hello Sir, freely contact me backstage as usual for lil discount on the said Felicity inverter ! Tnx

Very cool guy, I love his videos, he is actually one of my biggest motivation for planning to DIY my next Lifepo4 bank upgrade.

adrusa:
I actually mean "dangerous dangerous", but not in the way many think. Lead acid and our inverters have been married from factory. Most inverters will cut off from battery around 10V. Your battery's SOC is still substantial at 10V if you have some reasonable load on. So, the arrangement of your inverter cutting off at 10V suits the Lead acid battery very well. When your inverter cuts off your lead acid battery is unlikely to be substantially at risk of destruction. The situation is different with Lithium Battery.

Your Lithium battery's voltage will not drop like that of lead acid. So, when you have used 80/90% of your Lithium battery capacity, your voltage is still well above your inverter cut off voltage. So, before you inverter cuts off at 10V, your lithium battery will be at or precariously close to dangerous levels. However, if you have a good BMS, it will cut off your battery before it gets to this dangerous level. But, some BMS have a reset button which allows you to reset your BMS and still fire your battery a little more. By this time, your battery may actually be on its deathbed.

I therefore opined that you should invest in a battery monitoring system if you are putting money on Lithium. If you have batteries that has BMS that can talk to you, another monitor may be redundant, but if your BMS is deaf and dumb, it is advisable to have a monitoring device to monitor your discharge rate, your voltage and your DoD. Lithium battery is less forgiving of abuse than lead acid batteries. That is the (potential) danger.

In addition to the battery BMS, I have the volt-out terminal of the SCC controlling the on-off switch of the inverter. With the LVD on the SCC set to 12.0v, inverter switches off at a voltage well above the LVD of the battery BMS.

Dam5reey:
Simply put, in order to use LifePO4, I must change my inverter to one with custom settings, that I can change float, bulk and Low voltage cut off..
That's why I learnt from several YouTube videos, what if you don't have time to babysit, battery monitoring is not an option

I think you can just get an MPPT SCC with the necessary parameters and hook it on. You can even go for SCCs with remote monitoring capability.

That way, you still get to keep your rugged and trusted inverter.

Dam5reey:
To me it's simple, any inverter that has custom settings to set Bulk, Float, and LVD, and also disable equalization, will do the job.. you can even bypass the BMS by connecting directly to Battery terminals. Since your charger will handle Overcharge and Discharge voltage.

I plan to get this: and try out the 24V 200AH LifePO4.

https://a.aliexpress.com/_B05a7N
The seller sent me the Manual in PDF format, it will do just fine..

You may not be able to bypass the BMS. Reason is that the BMS function is not limited to only high voltage disconnect and low voltage disconnect, but it also acts as a balancer between the cell series that make up your battery bank. Rembwr the lithium cells are of 3.2v, 4.2v, or 2.5v nominal for Li-ion, LFP and LiTo respectively.

So except your inverter is so endowed that it even has balancer capabilities, then it may not be possible to ignore the BMS.

That being said, I will so much love to see an inverter with those capabilities. It's gonna make life so much easier and sweeter, mostly for DIYers of course. You only need to buy your LFP cells, the connecting wires and nuts and then you cook for yourself a sumptuous LFP meal as your pocket permits.
