The price u bought it should answer it.
How much?
The cheapest mppt (powmr) is about 60k now from 3rd party.

I bought for 40k on jumia,it 30a mppt

What is the KWh of your system, or will a 280AH 24V LiFe04 be able to do this also?

My system spec is in my signature. While lithium can easily do 1C, I make it a rule not to do above 0.3C of my battery capacity so I will not service that you run your load above 0.5C which in your case will be 140A @24v and yes thats more than enough for a face hotplate but ofcourse it will depend on how long you are cooking for.....
In summary it's all about knowing your battery capacity and managing it accordingly to your needs.

Juror:


Yes you can specify battery type and some other parameters directly on the inverter using the dip switch combinations but this doesn't still give you the flexibility of setting the voltages.

No VCC doesn't take care of that. Temperature affects the battery charging process, the TBB inverter comes with a temperature sensor which would be attached to the battery and enables the inverter to adjust the charging voltage based on the battery temperature.
That's what that part you share is referring to.

It's noted bro

Average of 8hrs like daily and if i can get like 10hrs from the inverter or solar , it will be nice

gadgetplanetng:


How long do you need to keep these things on? TV? Fridge?
That matters since no solar, then check the back of the TV and back (or inside door) of the fridge how many watts on the sticker.

Or if you use prepaid, how many units do you consume in a day/month?

Post those, experienced people here would be able to help.

I've gotten a lot of help from here too.

You have been very helpful.
Thank you

Hi guys,

I got a new "toy" Ashapower 80amp MPPT CC,

Anyone with me on this one?

It's got some additional technology to make the non-smart inverter smart by connecting the Inverter to it rather than connecting it conventionally to grid directly...

I am still trying to process this, please can you be kind to re-explain? Because if what you have written is what I think it is please don't try it unless you've confirmed that the CC has some compatibility with the inverter to be connected together that way

ojesymsym:
So much bad blood in recent times.

Anyway, a Chinese seller is recommending a BYD 300ah as an alternative to Eve Lithium, anyone has any previous experience with it?

Are they brand new with capacity result? Is price not to far from that of Eve? If both checks out grab them with your full chest

Capacity test is 280ah from the 300ah. Was used electric vehicle before. Price is $75 before shipping.

Biko i need answers on the way forward

Enyinne:
Finally here to seek advice on this solar installation. I hv a plan to have 3.5kva or 5kva solar to power my house. I will like a neat and compact sizing hence am looking at going for the lithium battery.
Hoping to power 55inches smart tv , 394 liter Samsung refrigerator, 7 led light , 3 rechargeable fan .
I will like to start using the solar but which comes first as i intend to start without panels but will buy the panel along the line and build up .
Pls Whats the wattage of this 2 electronic as I couldn't calculate it .

Pls i need advice on the way around this thing .

Thanks

@Ojeysky, let me allow you read the diagram and details from the datasheet then let me know if it's still not clear to youbro... Things are indeed fast changing in my opinion...

Let me share parts of the datasheet...

Many thanks and respect to the one I rather call "Prof" I met here... His been providing me priceless guides from the day one i started this venture with 6car batteries... Prof, thank you so much, may your batteries keep producing same power from day one till end of life! Lol... Thank you so much. You know I appreciate you Prof!

Menh! I have been struggling to load 2 screenshots here... Not even one loads... Keeps showing me either load memory or wrong reset code...

Now u have it bro... I have been analyzing this new "toy" with one of the top guys here whom I refer to as "Prof" one of the guys with the big batteries... Lol... Am not sure if he likes his name mentioned... So he agrees with this new stuff so am proceeding soon...

So sorry if the writeup is not clear but the diagram explains it in in one goal

Thank God for google search strings that led me to this thread, The knowledge gained here and reading from other Google related reference site is sufficient to make right decision.

That Solar Talker pwm tagged Mppt was my preferred charge controller months ago until u found this thread.

I appreciate all who have helped so far knowledge wise, may God reward you all.

Alright I see the inverter is designed to integrate with the external CC nice

ojeysky:


Alright I see the inverter is designed to integrate with the external CC nice

But in this case, it's actually the other way round.. It's the CC that is designed to accommodate and be able to make the inverter smarter by releasing or disabling AC power to the connected inverter as a function of any preset values keyed into the CC... From what I read in d datasheet, it uses a relay to get this open and close done as a signal from the CC microcontroller...

But I still have one gray area "prof" and I are still not in alignment...

Now, considering there should be two DC cable that are conventionally meant to meet on the Battery Terminal, one from the CC and the other from the Inverter...

Question is, any negative impact if this is reduced to one by sending the DC cable to the battery via the Inverter terminal instead? This is just to again reduce double efforts of double cabling... Since the inverter DC terminal already has contact with the battery, it's shorter to make the CC send its DC signal or current through the same inverter Terminal...

Also note that the CC release of DC is I/O meaning its either CC or Inverter releasing DC current per time

What would be your though @Ojeysky...

If you don't get the point, I could share a paper sketch am still looking at... .

My Solar community I greet you all from my Lunar abode.
Help me to celebrate my 6years journey into use of solar energy. It started in the year 2016 with 2x150AH 12V SMF LA Ba3s which were decommissioned in the year 2020 following decline in storage capacity. Currently running on 2x100AH 12V LIFEPO4 Ba3s courtesy @Juo,which started 2years ago and today celebrating 2years of use.I must say Lunar energy is sweet as I run all equipment completely offgrid.........
Posterity will not forgive me,if I fail to commend all who had contributed in humongous amounts the knowledge acquired via this space. All I have learnt is from here,even though it had started working on electronics and electricity from a tender age. I do every connections my self and I give kudos to all here both online and offline for the wealth of knowledge........

Any changes in your LiFePo4 capacity after 2 years?

The highlighted part will be possible if the inverter has integration option for the CC whereby the CC acts as micro inverter to the inverter itself. This is what I thought the screenshot you earlier shared meant (though the text is blurry) but from the semantics diagram that seem not to be the case. At this point am not sure of what Union exist between the CC and the inverter.... You can wait for that person with big battery you refer to advice.

While you will still get your response from him, attached is almost 2 years installation. Performance is same as it was in day 1

If it's truly new BYD, then I'd say go with it. But it's possible that the market it already infused with fake BYD LFP products and used ones sold as new because they have very great cells. Their blade batteries are used for their line of Electric Vehicles and Tesla has also indicated interest to use their blade batteries. The blade LFP batteries are noted for great ruggedity, very low risk of fire even when punctured through and good density.

So if you can arrange for the chinaman to get you the BYD blade cells, by all means go for it.

ojesymsym:
Ah thanks, seller just confirmed used (90% new)

AH! Then most likely salvaged from BYD EVs.

ojeysky:

Wow!

I'm in 1yr+ on LiFePo4 and at times the thing just seems too good to be true.

Mine no change at all either.

In Jamaica, he also charges his Nissan leaf with it. His solar array even seems to be child's play compared to what some of our guys on this thread have.

And in his interview he made mention that the Jamaican government reduced the custom duties on some imported solar items to improve affordability.

But for 9ja, hmm it is well.

And just a little off topic, it's annoying that Nigerians have to sit for IELTS and Jamaicans don't have to. Jamaican English is nothing compared with English as it is spoken in Nigeria. Even most brits themselves cannot match up to Nigerians in Test of English Language.

What you call 'double effort' of cabling is actually a critical code and safety and operability requirement.

There is something called voltage drop which happens when you pass relatively large currents through a cable and this is the force you are working against - uncompensated voltage drop can make your battery undercharge and/or reduce the useable energy Wh from the battery.

The kosher thing to do is to run CC cable to battery busbar and seperately run the inverter cable to battery busbar. If you must share DC cabling between the inverter and CC then you need to upsize the common cable gauge to be enough to carry the combined maximum inverter and CC current without overheating and with minimal voltage drop and yet this practice is strongly discouraged.

This CC appears to be attempting a very rudimentary Ignore AC for battery/solar self consumption algorithm (mimicing ESS like behaviour) - you are better served using one of the hybrid inverters which make DC solar energy directly available on the inverter AC bus or implement thesame logic this CC attempts with a cheap AliExpress battery sensing (LVD) relay. Essentially your CC is switching the Grid supply ON/OFF - this is very coarse control because what you really want is solar (and sometimes battery) priority where you source only the balance of energy that solar (or battery) cannot provide from the Grid.
