Thanks, however i want the compact 13amp type, for quick use in shops. My trusty unit just quit working

Ok no probs !

My brother na really adventure oo. I actually bought 3 types of batteries after watching a lot of YouTube on set ups and performance.

1.) 57 modules of Nissan Leaf
2.) 6 packs of BYD batteries
3.) 100 cells of 38120 LFP

Did you ask an earlier question? About how David Poz rearranged his collection of 8 packs 24v (25,2v) BYD in the video : Parallel Cells in Big LiFePO4Battery Modules. He found some weaker cells in the modules. What I think is this>>

There are 7 cells inside each of the BYD modules.

In his earlier video: davidpoz-20191211_ Series Connecting 24v Modules into a 48v Battery Bank, he did a (7s)2s4p arrangement. So he had a bank of 4 batteries, each consisting of 2 units of 24v modules, each of which contained 7 cells in series.

In the later video: davidpoz-20200207_ Parallel Cells in big LIFePO4 Battery Modules, he basically broke open the modules and connected the individual cells in a 4p2s7p arrangement. So he had a bank of 7 batteries, each consisting of 8 cells. Each of the 7 has 4 modules, each with 2 cells in series.

I hope this helps

would like to get hands on a pair of Chargery BMS-16T, if any one has any? Get in touch

I have been doing some research with AC & DC coupling of solar into a Victron inverter-charger.
Using a Fronius Primo 4-6-1-Light for AC coupling, and a Victron MPPT 150/70 (thanks, Saipro!) for the DC coupling.

Will be reporting some of my findings in due course.

For now, I can predict that this sort of system has incredible potential to generate significant electricity at low costs and high reliability into the utility grid, if backed with
# a feed-in-tariff for solar prosumers and
# distributed energy storage systems

what and what can this power?

Yeah but I finally figured it out. David Poz was a big influence in my purchase of the BYD batteries. I have watched his videos and set ups countless times.

The batteries actually have 8 cells, not 7 like you mentioned and he connected his in 48v set up. I will be connecting mine in 24v set up then parallel all the individual cells like he did. This will help me eliminate having multiple BMS as system will be one big pack.

His capacity test was a failure though and people actually complained about the batteries especially as they didn't meet up the rating by battery hookup. I have bought them so will just have to deal with what I see when it arrives. If not for COVID-19 I'm sure it would have been here. Thanks though.

See my diagram of what I think is the parallel connection he did.

Is having 8p of strings not too much? I think it's usually better to reduce parallel strings as much as possible so weaker strings don't kill the stronger sets.

Looks like you have a select few you actually wanted to answer your question. My own is you for don direct am straight to them instead of asking the house. Enjoy.

oga no be so oooooo. he asked me those particular questions which I tried to feedback but honestly, my questions are for the house. i will definitely appreciate yours or any member's input.
thank you

Fronius is a great brand. Most Nigerians are not a fan of AC-coupled system for good reasons- no AC to play with. Though most firms that do most of their business in the day prefer it to lower the cost of diesel spent on generators. Anyways, this your system is interesting and I'll like to see more of your findings. Cheers.

I have already done that. Actually I think I was the only one who answered your 2nd question with all the facts. You can go back the previous page and read it then let me have what you think. Well done.

This is a different angle I was not aware of so let me state the facts. David Poz had 8 modules which he connected 4 in parallel then the 2 sets in series to give a 48v system (4p2s). He then connected the individual cells of a string in parallel, that is for 4 batteries at a time.

I am buying 6 batteries and would want to connect them all in parallel for a 24v system. So the cells of all 6 batteries I will be connecting in parallel, how do you see this?

Actually, during the capacity test of the batteries David alluded to the parallel cells helping and adding an extra 1kwh to the system. If I don't do this I will have to buy 6 BMS & 6 active chargers to be able to run my system oo. Abeg that no be small money. QNBBM costs in excess of $150 each.

I have no experience of how these particular cells perform but from what you've stated above, I will suggest that if going parallel is your only option, then do parallel at cell level first before you then put them in series so you have one large bank of 24v instead of multiple(6) banks/strings of 24v in parallel.

I dont understand

You're welcome

Thats the plan my brother, e no easy. Thanks.

Though it's still a large set of parallel string but I guess it's still better, you could have gotten larger cell capacity to reduce the need to parallel. Don't know if they exist in your kind of cell chemistry though

Have bought stuff from him before and he delivered fine at that time. I don't know of the present

I bought 4 panels and a charge controller from him a few weeks ago, he was very prompt, his prices too are reasonable, I recommend him!

Five houses? I see millions....

But this information is still not detailed enough.

You need to state the power consumption (in watts) of each of the appliances you want to use in each house. Will you use the exact type of appliance in all the houses? How many hours do you intend to run the appliances?

These details are important because it will help to know the size of inverter, the number of batteries,solar panels and size of solar charge controller you will need. The cost of the individual components will give you an idea of how much to budget for the project.
