Thanks. It's copper that I tinned. I wrapped it with neoprene and electric tape. Pix of the bus bar & dimensions below:

Thanks for the reply. Do you think it would be worth the effort to undo it and reconnect diagonally?

I know (now) that diagonal wiring w/busbars is preferred - especially for large battery racks - but I didn't realize it until AFTER I wired everything. I have 2 banks of four 100A 48V server rack batteries. I wired it with the lead coming from the CENTER of the bus bar (for both - and +)...

I ended up finding some neoprene covers and then wrapped red electric tape around the + bars will complete it by wrapping black tape around the -

Nevermind. I was able to power up with the batteries and get most of the parameters set.

That's what I figured, but this is my first system and I just didn't want to do anything that might damage my Inverter. It seems that there are a plethora of built-in safety features to prevent newbies like me from innocently destroying it.

OK - Forgive my stupidity, but It is going to be a week or more before I get my SOL-ARK 15k hooked up to the grid. Meanwhile, I have connected my batteries and solar panels. My question is, can I safely power up my 15K via my batteries (leaving the PV input off) in order to set parameters and...

Thank you everyone. Great examples and great ideas. Much appreciated. Had 1/2 of my panels installed today. Sol-Ark 15k is mounted. Batteries mounted and hooked up. Should all be complete tomorrow - can't wait to "flip the switch"!

My Inverter and batteries are almost ready to go "live" as soon as my panels are installed. I have 1 issue to resolve...I am not sure how to insulate my (tinned, copper) battery bus bars for safety. I will attach pictures. If you have any suggestions, I would love to hear them. I live in...

Brain fart

I ended up buying the 15K and plan to install it in 4-6 weeks

It worked great.

Yes it did. Thanks for the response and I agree and have since bought the 15k. I hope to install it in the coming weeks.

Perfect. Thanks...I mean danke. ;)

Thank you all for the fast and great responses The Sol-Ark 15K has 2 - 200A breakers for each (of the 2) battery terminal blocks.

I am preparing to hook up my battery banks (2 banks, each w/4 100A 48V 5.12kWh server rack batteries) to my Sol-Ark 15k inverter. According to Sol-Ark (I emailed support twice to verify), I only need 2/0 cable for each bank. Can anyone triple check this for me before I buy the cables? I will be...

Ok. Yeah, I thought that was odd. I will definitely use equal length wires to and from the bus bar. I will also space out the lugs as much as possible. I am able to get these for roughly $50 USD including the hardware and insulators, so I was willing to make do with the bolt patterns...

OK - thank you again. I am adding a link to the bus bars I am considering. I have already ordered and received the tinning solution to do myself. Using your 2 banks of 4 batteries idea (with your drawing attached), would these bus bars be adequate. The site is in Spanish, but the bus bars are...

Yes. That is what I will be doing. I forgot to add the picture.

I probably should have been more clear. I have rarely seen a setup with the batteries stacked without space. I just want to be sure I get the right size rack for my needs.

I will be receiving eight 48V 100A server rack batteries in the next week. I am trying to decide between buying or making my own rack. Do the batteries need space between them for ventilation/dispersion of heat, or will they be good to mount directly adjacent to each other? Thanks in advance.

This is the very video I watched that convinced me to do my own.

Unfortunately, I have not been able to locate it here in México. I am making a homemade version to try. I'll post the results here when it happens.

Thanks for the answers. I'm fine to do it if I can find the nickel or tin solutions here. I just haven't been able to find it yet.

Hi again, I defer to the expertise of many on here who have guided me so far... Because I live in Mexico, I don't have as many things available to me as in the U.S. I have found copper bus bars, but they not tinned. Because I live waterfront on the Caribbean Sea, the salt air rusts and...

Yes and thanks again. I May still use 4/0 just to be sure and allow room to expand, but I am truly humbled by you and others who willingly take time to help and educate others. I’m a retired schoolteacher, so I’ve always tried to share what I know with others. To be the recipient of that is...

I went ahead and e-mailed Sol-Ark about this and here was their response: Me: I have ordered 8 - 48v LiFePO4 100A server rack batteries to use with my 15k. 2 questions: 1) Is it better to use 2 banks of 4 batteries (1 to each battery input terminal) or all 8 into 1 input? 2) Is 2/0 awg...

OK - It is apparent that this charger was designed for Lead Acid batteries. Thanks for your help. I'll get one designed for LiFePO4. Thanks again

OK Thanks - good to know. I will see if I can find the specs.

OK..Thanks. Better safe than sorry. I'll go with the 4/0

I just ordered my 48v 100A server rack batteries. I also have a Club Car 48v golf cart (and charger). Can I safely use the Club Car charger to charge my server rack batteries? I figured, I could buy a Club Car charger receptacle to then connect to the battery terminals. I believe the charger is...

Thanks you also!! Great setup, too. The pictures are helpful. Are you using 4/0 wire from your buss bars to your 15k?

Thank you, thank you! What an amazing and thorough response. This is incredibly helpful.

Hi, Although I have learned a lot from research and this forum, I am still pretty new to this. I finally was able to purchase 8 - 48V LiFePO4 server rack batteries (5.12 kWh each) to use with my Sol-Ark 15k. The batteries come with 8 inch 2AWG cables per unit. My questions are: 1) Is 2AWG...
