You probably have something against Deriy. Deriy makes pack with most of the popular cells and they are all brand new. Many have been able to pull full capacity from it too (3.5v - 3.0v).
As for Hithium cells, they are specifically built for Ess and they also quote longer life cycle for their cells.

clevermugu:
investing 1.8m or 1.9m for a Hithuim 48v pack to a Chinese in far away China and waiting for 3months,doesn't make any sense. what if there is serious shipping delays or something happens
getting Valto's Eve 48v pack for 2.2m within 24hrs of payment is far far better.

I think he is talking about it from a 'Better deal' perspective factoring in the price difference, wait time and uncertainties around logistics (according to his opinion).

I tried to search for Valto's packs capacity testing or tear down but so far there is none.

My guess is 1 of Ur is 150-180w. it can work for 24v inverter as long as U AV 2 pcs or more in series.
The part of not charging Ur battery well is what U need to pay attention to.
What max wattage do the s generate,
What is the stated wattage of 1 .
How many pcs do U AV on Ur roof.
Which direction (cardinal point) are dey facing.
U might even b using a lead acid battery that has been abused and can't hold charge like before.
What kind of hybrid inverter do U own.

Dabss:
Good evening guys, please is to connect 12volts solar s in series to a 24volts hybrid inverter? My setup has been like that for over a year but a new technician said the s are undercharging the batteries.

Inverter voltage has nothing to do with voltage.

What are the specs of your MPPT and s

So you are basically saying paying 300 - 400K for an express service is better... No sir... That's too high to be considered any advantage...

At the end of the day... Preference is all that matters for folks...

lolz , i don't have anything against. their Eve pack is around 2m-2.1m, so why will i invest such on a Chinese in far away China and wait for 3months ,when i can get it almost the same price in nigeria immediately. what if something happens

2.35m updated price for Eve pack.

Bruteality1:
I think it's completely normal for solar s. I haven't seen my 4x550w generate more than 1.487kw during sun peak hours. You'd have to add more s if you need more i think. The sun these days is not that sunny too. It's cloud mixed with sun. I think I'll get more when the weather is bright

I think the max your inverter can output is 1.5kw cos that 1.48 you're getting is poor compared to what the percentage output should be

CuteMaro:

2.35m updated price for Eve pack.

lolz. so people pay 2.350m for thier Eve pack and wait for 3months , when it can be gotten 2.2m from Valto here

thank you very much for the reply. I was using 5 300watts s because the maximum wattage for the inbuilt charge controller is just 1500watts according to the manual. I guess that is why the initial installer installed them in series. The new installer is advising me to remover one of the s and connect the remaining 4 in parallel.

HeavenlyBang:

I don’t use an MPPT. I have 5 300 watts s.

Yeah i know but the sun here is not that strong enough

Dami did capacity test but he faced many resistance when he posted the result here and on the telegram group.

Waiting time is the only disadvantage for Deriy packs and some have also been lucky to get it under a month.


From all the major suppliers, brand new hithium 314ah with 1c ratings currently cost 39-40USD,shippong to GuangZhou additional 20USD.
Even eve 280k v3 cost is around 40USD/cell
The cost of shipping 16 cells to Lagos <= 200k
200A terminal <= 16k
Jk200a BMS with 2a <= 70USD
4. inches display 20USD
3.2 Inches 9USD


Without casing, the total cost is circa 1.5m.

You see, even Deriy makes reasonable profit for selling in that range.

Hithuim cells and Eve cells not the same. so your 300 -400k gain is wrong..their eve pack for 3months wait is 2.350m , when it can be gotten instantly for 2.2m in naija.

There are testimonies on this thread, I think.

This is exactly the route I'm taking and it's very cost effective. Abeg where you see that BMS for $70, because Kayla is giving me for over $100 o. Drop your Whatsapp let's talk if you don't mind.

I only quoted 70,actual price is less than that.

I'll like to know the price of Deriy packs with EVE cells.

connection is dependent on the charge controller specs.

2.350m and u wait for 3months

That means they will change all their existing sumo to DC submersible pump?

Yes

Oga preference Have u seen dia latest prices ..go n make n enquires n com back to edit your post. U go change preference wen u see dia new prices.

Kindly snap d side of Ur hybrid inverter where d info is, Ur installer wanting to put all 4 300w in parallel might mean Ur hybrid inverter inbuilt charge controller might not be mppt but rather pwm
Ur doesn't fall under the category of wat they used to call 12v . 12v s are d likes of 100w, 120w, 150w and some 200w cause their vmp is 20v and below.
Ur installer needs to know this, if he will put all 4 300w in parallel, Ur cable won't be able to sustain the amount of current that will b ing through it.
I'll recommend to talk to a different installer as U don't AV much knowledge about this.
Snap Ur setup (inverter, cables used and battery)

this is the specs for my inverter inbuilt charge controller (mine is 24volts ) and the other picture is one of the five solar s installed.
