1kwh in the day and 24kwh in the night is not what I meant. I meant as a total it is very easy to do 1kwh every hour for 24hrs to give 24kwh.

If you have one of there NEPA prepaid meters then you will understand what I'm saying better.

That mean you didn't read my comment well then. NiyiOmoIyunade does even more than 25kWhr daily. My argument was that the figures he inputted is proportionately inaccurate, thus the result.

Okay, sorry about that.

No, it is a 2s2p configuration

ceaser:


Is that 4s3p config for the 48v system?

I have got some neatly used 24v gear for sale:

1. 3kw MPP GK 3024 4kw panel, 500V 80A and can do up to 60A AC charging. - 180k
2. 24v 50A adjustable current and voltage external charger (used twice) - 70k
3. Circuit breakers and SPD - 80k
4. 24v 60/100A Daly BMS (new) - 40k

They are in their top performance.

On a side note, men the Deye is huge and feature packed.

Still available for grabs

For does dat was asking of DC fridge we have now 206L 100w AC/DC all u need is ur 300w panel and your 150ah battery and u are good to go going for a good price just dm me 09013128166

Nice.
Fridge or Freezer.
Picture is of freezer and you wrote fridge

Pls house, what is your take on this. Is there any better and cheaper alternative?

WE BUY DEAD/SCRAP BATTERIES!!!

We also buy off scrap/dead deep cycle batteries from any state to Lagos(T&C applies) .

12v 200a ..... N16,000
12v 150a.......N12,000
12v 100a.......N8,000
2v 500a.......N5,500

If outside Lagos state , send the scrap batteries to your nearby Lagos park & get your payment alert immediately after confirmatory remarks from me with the transport company manager / secretary or driver .

I took a look at the calculator. I am possibly using it wrong as I got strange answers

Very misleading actually. Anyone who depends on those calculations will cry las las. It should be taken offline ASAP as the calculated results bear no resemblance to reality. How can it recommend 1KW inverter for surge load of 2KW?

Packaged and ready for the new user

Yes, the same company makes them. It's the same circuit but with different brand name.

mctfopt:


So Steca and MPP Solar can work in parallel. This is good to see.

That's awesome to see

Good morning guys
I have been using this lead battery (car battery)for a while now but no matter how long I charge it, it doesn’t get to 100% it floats btw 96-100 percent during the day but at nights it drops to 80%. Is there any explanations for this ?

Ojesky willmaria kiekie1 adrusa NiyiomoIyunade mctfopt will really appreciate your contributions

DeathToBEGGARS:
i have been looking for it for close to 30mins and cant find it

Go to front page and scroll down to the bottom of the page, u'll see it after the last topic on that page....

Please see screenshot below - my first post on this matter, I stopped playing with the calculator when it was proposing a 12v inverter and CC for loads over 2kw.

I went and put in some test values again - the calculator is recommending 24v nominal battery bank and 2,500w inverter for a household that runs average 3000w and peak 5000w.

See how many charge controllers in 24v config the calculator has proposed? (like 17 to 23 units implied) See the PV array size proposed? (out of scope for most folks)

I happen to have similar load as input but properly sized as 48v nominal. I am doing just 4units of Victron Charge controller and 20Kw of PV Panels. My PV is grossly oversized for my day time needs and I run more than 5kw sustained at times.

You will need clearer parameters and more variables and certainly more work on the sizing algorithm to make this calculator into a truly professional sizing tool.

High level assumptions behind my test inputs.

8am to 4pm - 3000w load
4pm to 2am - 3000w load
2am to 8am - 1650w load

mank1234:

Thanks for your feedback.

I think you got the strange figures because your input are not real world values.

Firstly, there's no way total startup power of all your appliances will be just 2000W while you consume 750kWhr in a month.

Secondly, it's near impossible for you to consume an average of 25kWhr in 24hrs(from your first input) and your night consumption will be as much as 24kWhr.

If you input real world values, you'll get real world answers

Lead acid battery voltage will always drop under load. If it is lithium battery, which tends to maintain same voltage for a long period of time. Also, remember that car battery is not a deep cycle battery, so forgive it for not keeping to expectations when used as a storage battery in a renewable system.

Does anyone here use the Indian Soccerpower inverter? What is the maximum charging voltage? Especially for the 48v system. Thank you.
