I have two 5kw Growatt connected to single 30kwh lithium bank. Why did I do that? To increase the capacity of the inverter and also so it can handle the number of solar panels in play.

Please, is your Growatt 5kw an ES version?
What's the no load consumption?

jonescosmo:
They are not being compared boss, But if I may comapre them, I have a 5KVA Inverter, 8 Units of 220Ah Tubular (21Kah) setup in my Office. Backing up just my Server, Switches and CCTV. A total load of about 2.5Kw max and the Battery Backup Time is nothing near that of these Lithium Batteries with a wooping load of almost 7kw.

In all honesty. Tubular batteries did well during their regime but the game has changed. Lithium has taken over.
As we speak several combination of Lithiums are in production (See Table) but lets just stay on LiFePo4 for now.

I guess your 7kw load draw was done by the huge pv on your roof and not the battery.
If the rated battery capacity was in order, I you may still have pulled out 7kw load on it for about 2hrs and 20 mins... that's if I'm right.
Again, we're still waiting for the confirmation report of your battery capacity test.
Congratulations once again.

jonescosmo:
Thanks a whole lot Bros.
Just for people who might want to setup something similar, the space is 8ft x 8ft sha. I have ordered a 16Inch Extraction Fan from the USA, The fan is Temperature and Humidity Controlled, also has a mobile App for remote control and mmonitoring.

The "Tubular Gang" are meant to be decommisioned and sold off after fully testing the Lithium batteries and their capabilities. Those Tubular Batteries is going to be replaced by a 3rd 9.5KW Lithium Battery and the 2x 5KW inverters will be put in Parallel Mode (Teste this method already though) Or I would simply grab another inverter with 2 MMPT input Strings for my 10x 540W Panels and 8x 350W Panels, Felicity now has a New Model that has 2 MPPT Inputs , this:

and this:

Hehehehe, That my Generator is a 3Phase 6.5Kva Birtoli Gen and was retired since almost 4 years now by my 4 Years old former Inverter (3Kva iPowerPlus) Which I have now installed for my mom in Lagos (Picture Attached Below). So the small Gen is just there rusting out.

This new setup is aimed at retiring my 20kva Mikano Generator for good. And ofcourse Nepa People are not happy with me ooo. They came last week to inspect my meter and I showed them the panels on the roof. Hehehehe. I told them the I had to sum up the monthly 100k I used to recharge for 3yrs and yet the electricity will still not be available when you need it most times. so i decided to demote Nepa Supply on my Priority list and go for solar energy.
The two Genertaors might be auctioned out after a year of fully testing this my potential off grid Installation.

Please, let us know as soon as the capacity test is completed.
What's your total battery capacity sir?

jonescosmo:
Continued

Were you able to carry out capacity test on these Felicity batteries?
Some of us are still doubting the capacity, wondering where Felicity is sourcing its cells from that makes 15kwh 1.6m or thereabouts.
Even with letter B QR code of Eve cells (A-), it's still very hard to couple and sell at that price.
You've really invested cash in RE.
Congratulations.

NiyiOmoIyunade:
Yes it has bluetooth boss.

Thank you very much.

I'll reach out to you sir.

NiyiOmoIyunade:
I have 1 unit each of JBD 16S 200A and 16S 150A and both have 2A active balancers

200A JBD BMS price - 130,000
150A JBD BMS price - 90,000

Does it have Bluetooth sir?

samir101ng:
Well done on learning the quoting function One cold bottle for you

However, i don't think you will get a 300A JBD BMS here. I checked both their AliExpress Store and website and it seems out of stock.

What are you trying to power like this that you need a 300A BMS for ? I hope its a typo and meant maybe 200A.

I actually wanted 300A but if there's 200A, I'll go for it.
Please, drop the cold bottle for Oga Ojeysky who came to tell me the actual mistake I was making and correct me accordingly.
Initially I thought Valto was talking about Felicity Inverter no load consumption wrongly quoted.

Who get JBD BMS 16s 300A with Bluetooth here?
Indicate your price please.

Namzy:
You should have quoted to confirm

I'm still learning sir

IYGEAL:
Is this rate correct?

Good morning Boss

chigo4u:
Hello, does anyone know the current interest rate for Gtb and zenith savings account

GTB interest rate is nothing to right home about.

Ojeysky has put me through.
Thanks for the correction sir.
I appreciate.

Oga, you won't kill your boy... Lol.
I'm still learning and I'll get there someday.
Appreciation sir.

[quote author=ojeysky

Thanks for your correction sir.
I've learned

[quote author=Juror

I've this very model of Felicity inverter and no load consumption in mine is 80w. Quote me wrong with yours so I may learn @ Valto and IYGEAL

[quote author=IYGEAL

Please, correct me if I'm wrong as no one here was born with the knowledge of renewable energy.
Which one exactly if I may ask sir?
I think that's the proper way of making someone realise his mistake and also learn from it.

[quote author=Valto

Oga Valto, please what have I done?

Oga Niyi, George and others.....
Please, put me through on how to set TriStar 60A 150 Vdc CC to charge Lfp battery.
Thanks

[quote author=Juror

Boss, the no loads consumption for the model you've stated is 80w.

[quote author

TriStar Mppt 60A 150Vdc.
Thanks sir

[quote author=Juror

It's actually 80w from my measurement and I've maximum confident in it ( small but has mighty power).
The wattage of transformer based inverter generally is high. Once your battery bank is properly sized, you have less time to bother about things like this.
I was majorly concerned about adjustable charging features, lvd, lfd compatibility and it has all these.

Can Morningstar Mppt CC charge lifepo4 battery?
I couldn't just find the lithium as other battery chemistries were clearly stated in the manual... Do I have to go through custom settings?

[quote author=toyeoye

From what you've said sir, your loads should be about 600w or thereabouts and I don't know why your fully charged battery bank can't power these loads (about 6.6kwh) for 11hrs.
Again, your CC isn't all that effective.... Sorry to say this.

[quote author=NiyiOmoIyunade

That's very good.
Thanks

[quote author=samir101ng

Any room for upgrading (firmware)....
I've 60A Morningstar Mppt and I was planning to put it on sale.
If the new features are up to date, then we'll compare it with Victron and Deye before making decisions

[quote author=desiji

I understand sir.
Congratulations

[quote author=desiji

This your iron rods ehhhh

[quote author=ajabani4allah

Frankly speaking, nobody here will be able to give you positive response. As earlier said, try and buy from a reputable agents on Alibaba and get it tested.

[quote author=earthrealm

Nice one.
Thanks my guy

Any group purchase of cells in this forum?

[quote author=mctfopt

Majority of reviews now na fake.
Most companies do beg customers for positive review. Some do offer give away items for dropping positive review.

[quote author=Valto

Gloria cells na premium.... price no be here
Sandy Zou gives122uds for 280ah though claiming 299ah-300ah is the real capacity with busbar and nuts.
Only God knows what may likely happen with dollars rate before Dec. Unfortunately, the targeted masses in Nigerian market are poor citizens who are busy looking for daily meals/water and cared less about electricity.... Na only few of us dey talk about renewable energy

To be very sincere, this dollars issue just dey make me vex anyhow.
I wish someone could take me back to "old time religion" where freedom, rest of mind, affordable price of goods, love, unity was embedded.
