I finally have 90% of my system configured. Battery bank, 4 12v 100ah connected in 2s2p. Have battery monitor, lynx distributor, Victron mpg soalr controller. i have my Giandel 3000w inverter. Have it all connected, including filter guys precharger switch. Here is my question I won’t be able to...

thanks

I have a t fuse between positive battery cable and my lynx distributor. I would like to add in a disconnect. using this one: https://www.amazon.com/gp/product/B000MMC914/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Does it go before the fuse or after? Thanks.

Filter Guy Quick question, I am building you're pre charge switch, what gauge wire do you use inside the switch? Looks like 10?

Yeah I know!

Smooth One other question which I can't fathom, why do inverter manufacturers send such small gauge wire for the connections? my 3000w comes with 21mm Square wire which I believe is AWG 5. I don't get this.

You are clearly being a prick, have a nice day.

Funny man, ass hole.

Not ferric phosphate due to the charge on the iron atom.

Lithium ferrophosphate technically

Ah sorry see what you mean. The Phosphate "ion" PO4 is made up of one atom of Phosphorous and 4 atoms of oxygen. The PO is not polonium, thank god!

Lithium Iron Phosphate Polonium is deadly, it has been used by Putin to kill his opponents via acute radiation poisoning.

Believe it or not I have a PH.D! (chemistry) but this stuff get confusing with so many parts to consider. I then look at posts and the advice seems all over the place. 1. So 1/0 wire on all battery connections, yes? 2. This means the t fuse from pos battery to bus bar now has to be 250 amps...

Smooth if you read this I am trying to make sure I understand you're recommendations of cable size. You mean 4 AWG not 4/0 AWG right? Just as I delve more in to this I keep reading posts on here were people are using anything up to 4/0 to connect batteries with a similar configuration to mine 4...

I just bought a renology 3000W inverter it says keep away from audio and video equipment. It will be in the same room as a receiver and some set top boxes and two PC’s. Any body have a problem with inverters and emi? Anybody used ferrites on the inputs and outputs to tamper the antenna effect?

Thank you very helpful

Please see attached. Are both these layouts legitimate? In terms of connecting the parallel connections does the negative connection to the bus bar have to be on the "diagonal"? I have seen some info that insists this but other layouts that show straight thru so to speak. Also in terms of the...

If I bought more stuff the wife would lynch me!

Smooth I missed your post, so you recommend the victron balancer? I was looking at this as the solution. For $65 bucks you think its a good way to go?

I plan to install these as 2s2P. rmaddy / Nbtesh, would I set the power supply at 12v or 14.4V? Most balancing seems to be max not nominal?

So I just got 4 new expert power 12V 100ah LiFEPO4 batteries. I used a 20 amp charger and got them all up to 14.4V (max charge). I am monitoring them as they drift down. But I was wondering should I top balance them by arranging them in parallel and use a power supply to top balance them? Any...

Well aren't you nice, hey man just learning! And once again thanks for all the help Smooth. Its much appreciated.

one more dumb question, I am looking at the mega fuses and some reference a voltage? Can I pick any or do i have to pick a specific voltage. Thanks.

much appreciated.

Once again thanks for the help I think I am getting there. After some more reading I have decided to go with the lynx distributor as the fused bus bar solution. Can you look at the new layout and see if I have it right? Especially the shunt/battery monitor part. I think I only have six...

Smooth/Derpsy Thanks folks. So second attempt but still have questions. I have attached the pdf and jpeg. See new layout, notes/questions: 1. I split the battery side in two for simplicity ( I realize batteries don't have 2 pos and 2 neg!) 2. I changed the PV to series, that was an eye opener...

Ok I am confused:rolleyes: But let me see if I can answer: 1. the reason I did 2S2P, is because the turbine is 24V, and therefore I had to make the battery bank 24V? so Therfore the 2S2P config gives me 24V for the PV array? 2. So what should the wire be for the batteries and the inverter if...

I would like some help to maker sure I have this setup worked out correctly. Use Case: This is being built for fun and to see if a large renewable system could be used to provide a substantial upgrade to our energy needs. So really a test bed to learn the ropes. My setup is shown below. But a...
