Ok thanks my initial plan was to go 24V but lead acid, since i am going lifepo4 i had to settle for the 12V

The inverter does not have inbuilt charger it is a stand alone inverter

Ok the makeskyblue 40A or 60 which will be better as i don't want to use more than 4 panels 250-360w panel because of space, make landlord nor go vex for the roof mata

I will search for the 12V LFP charger

JUO:
first test. I think is better to stop at 3.1v. Let me observe the voltage after 3.1v

ojeysky:


Yeah since it's still new you will get a little above capacity (say 110AH) just for a few cycle. Trust me it was almost full by the time you started the test

JUO:
dc watts meter. Battery was not even fully charged and I stopped at 3.2v

spartacus11:


Wow thats nice was it 4 of the battery you connected in series or it was above 4??

JUO:
I stopped at 3.5v/14v

JUO:
4pcs in series

ojeysky:


Depending on charging source, at 3.45v can get the battery full.....you were probably already at over 90% when you stopped. The charging current would have tapered down if you allowed it a few more minutes. Just curious why did you stop? Were you doing the charging without BMS?

JUO:
I have not hooked up the bms yet. I don't want stories. The bms I have is more expensive than the battery so I can't use it with it

ojeysky:


Lol that's understandable, as to BMS you mean your 12v BMS is over 100k?

spartacus11:


Ok so in calculating

Normal voltage 3.2V i.e 3.2x4

Or the

Resting Voltage 3.3V i.e 3.3Vx4

I will work on adding solar to the set up later, how many Watts panel do you think i need to plan for since i am going for the 12V lifepo4 bank

But i think i will start with Nepa changing first, bcus of Budget limitation, so what type of charger will you recommend?

This is the inverter i will be buying the 12V 4000W which is actually 1800-2000W in reality, its budget friendly and the review online seems to show it sine wave is actually clean

ceaser:


Is that AliExpress page?

JUO:
my system is 48v. This 4pcs is for research purposes

spartacus11:


Jumia Global item

JUO:

spartacus11:


Wow that's great 5Years amazing thats 48V 200Ah bank

ceaser:


I think you should be careful with getting the inverter via Jumia Global. Someone here has posted before of an inverter he got via Jumia global that was advertised as Pure some wave but turned out to be modified wave.

Some of those Jumia global also source the products on sites like AliExpress, so if not for the Corona problem that has slowed down things, I'll have suggested you place the order directly on AE yourself. I have seen this inverter on AE, I'll see if I can retrieve the link and post it for you.

just checked, batts were bought in mar 2016, 4yrs, not 5yrs

spartacus11:
Saw this somewhere

The LiFePO4 battery has hybrid characters: it is as safe as the lead-acid battery and as powerful as the lithium ion battery.

spartacus11:


Majority of Jumia Global sellers are sellers on Banggood, Jumia Global items comes with cheap shipping too, this same inverter is about 8-10k to ship from Aliexpress why jumia is 1200 shipping and 1750 customs

When ever i want to review item i see on Jumia Global i go to Banggood and check buyers reviews

spartacus11:
But this inverter i have seen some buyers review on the Banghood and YouTube, and they agreed the sine wave in clean but the ratings of the inverter is not as stated that is a 1000w is probably 300-400w in real terms.

I can do with that but if the product go last na waytin i nor know,.

The rate brands dey cut money for inverter is just too much

Jesu. Permission to use pictures?

suddenly it feels like dry season all over again. with daily harvests topping 42kwh and instantaneous breaking the 10kw barrier ....
indeed, the sun is the answer!

adrusa:

I bought the 48v Felicity lithium and my first impression is not good. I tried to do a test drain overnight.
It gave me about 90AH drain overnight. I then set my Water Pump on it to drain it further.
I got to about 115AH when my inverter shutdown at about 49v. I wasn't sure which shut down first,
my inverter or the battery. But the battery was still (or back) on when I checked. At this point, I can not
recommend this battery based on expected AH output.

Hello GeorgeD1,

After this your post I went hunting for the Morningstar CC that offers 200A and could not find. Could you please educate us on how you achieved the 190A showing on your screen? A lot of us are willing to learn.

While at it what's your cable size for such an amperage. Thanks. I'm also interested in the number and rating of panels that can give above 10kw instantaneous.

JUO:
I know he has 4 cc. Oga please come and explain more we are waiting. I pray make I no thief because of you

spartacus11:


4 years and 3 months. Is like you know how to maintain lead acid

Which brand?

SolnergyPower:
Please take a look at what a 1.5HP was drawing. 1.4Kw. Any explanation for the difference compared to your calculation?
