Hello!

You will need a 5kVA/6kVA inverter hybrid (Deye, Growatt, Tbb) or conventional type (victron, Tbb, felicity) if you need to run both the AC and pump simultaneously

But if you plan to be self-conscious and know you won't run both together, then going for 3.5 kVA is a better choice.

For the ideal solar power, you will need around 6,500 Wp of solar panels (Jinko, JA, Longi, Canadian) and a 120A solar charge controller.

Battery choice (Vestwoods, Deriy, Pylonytech, Growatt)

Lastly, with your budget i see things coming together in a 3.5 kVA range, especially when inverter, solar panels and BOS are all factored in.

quote author=Ahyjo post=135077118]Hello experts in the house. I’ve been following all the discussions diligently especially the recent ones with regard to the lithium batteries. I am about to upgrade my system to be able to take a 1.5HP AC and also my 1HP submersible pump. Please I need your advice on the appropriate inverter to get ( both KVA (minimum required) and brand ) , the best lithium battery (14-15kwh) and CC (if the suggested inverter is not hybrid), and lastly the appropriate PV array. Thank you. As we all know these things don’t come cheap, so it’s better for one to do due diligence before investing in them, and there’s no better place to get appropriate information like here. Please advise me based on experience and not brand specifications.

My working budget is 3M - 3.5M
Kindly advice please.

Except they're not all brand new, at least from the one I tested.

The problem with Deriy 14.3Kwh Hithium White Battery with MCCB is the cells are not brand new. See the attached image of the QR code. How can you say cells manufactured in 2021 are brand new?! Or are these fake QR codes? Whichever it is, it's still false marketing.
The BMS (image attached) was programmed to charge at 40amps, new cells are supposed to support charging at 1c. Or are the Hithium cells in Deriy different?
In Southern Nigeria lifepo4 needs to be charged as fast as possible because of the weather, the sky is not always clear like in the north. So anyone with high PV output should be able to charge at 1c or 0.5?

One more thing is the Deriy 14.3Kwh Hithium White Battery with MCCB is not DIY friendly because the cells are welded (image attached)
It won't be easy to replace a cell if something goes wrong in the future. DIYers should have this in mind before buying Deriy battery pack. You get what you pay for but KaylaDeriy shouldn't be marketing these as brand new, they're definitely not.

Nice community you guys have here, researching this battery to get more info & Google landed me on this thread. Capacity test to follow soon, these are first observations.

Does Deriy have packs with EVE or Catl cells or they only use Hithium cells?

Please you need to create a warehouse for battery stocks in Lagos, Nigeria. At least 6 months to 1 year worth of stocks and segmemented accordingly from the most purchased battery type to the least purchased. Having to wait till June/July for next shipment is not good.

Actually 3612800 you'll get 28kwh from Deriy, 2 black hithium battery.

HeavenlyBang:
3.1m for a 10kwh battery is absurd. You fit add 200k buy 28kwh of Deriy.

Thanks for your waiting, responded.

Mavor:
Please do you have a 10kwh Deriy LiFePo4 battery available? I sent you a Whatsapp message, no response from you. Thanks.

If this is how you have been connecting the Black Stacked battery, you are doing it wrongly bro.
One of your DC cable should exit from the first battery and the second cable should exit from the last battery.

The white has 4 wheels to move easily, while the black doesn’t have. Each pack is about 120kg, so the wheels can help a lot if you want to move the battery.

The white is standing installation, the black can be stacked up to 3 or standing installation.

The screen of the black is touchable, while the screen of the white one is not touchable.

HeavenlyBang:
What's the difference between the white and black?

Yeah, I finally speak, in fact, I have been silently concerned about you all before , thanks for all your support , I am very happy to meet you people here!

Kayla you are here now, Good one...

Who said Deriy cost 1850000 each one if you buy 3.

If you buy 3 of the white hithium battery, the price is 1780950, so 3*1780950=5342950.

If you buy 3 of the black hithium battery, the price is 1687950, so 3*1687950=5063850.

Dam5reey1:
Assumptions:
Mercury Tall Tubular 220AH 12V X 16 units = 42.2KWH
16x 340,000 = 5,440,000

Deriy Batteries LFP 14.3kwh X 3 units = 42.9KWH
3 x 1,850,000 = 5,550,000...

So why Should you Buy Lead acid
