You can split the panel wiring near the array I would still go with Victron depending on what server rack batteries you have

Expensive

Are you running Venus?

Apologies I was thinking of another make!

Aolithium do a nice rack

It won't balance because the cell voltages are well below 3.45v

Well thankfully lightning cables will be a thing of the past. What were those morons at Apple thinking ?

I have: 8 x 200Ah Lifepo4 (24V) and a JK B2A8S20P + Victron inverter, mppt and a Pi running venus I am charging to 27.8V (3.475v per cell) and the the cut off (at the inverter) is 25.2v (3.15v per cell) Should the capacity setting in the BMS reflect that I am not using "full" capacity ...

If you are in the Victron world a Shelly 1EM (Wifi) works well (with the added benefit of being able to use a second CT clamp on an EV circuit if you have one) It does not have the terrible lag that some Victron meters have

I would consider this normal best practice. The BMS is the last line of defense

One big difference is 2A balance on 3.0

I have had my Victron 1200W inverter / DIY 24V battery build in a shed for just over a year. I had a 3D printed mount made for the Overkill BMS and wanted to install and tidy up the wiring a bit. I had some 25mm2 / 3 AWG cables premade All seemed! well with the install but after a couple of...

@Matthew 2 why are you spamming this thread with uninteligible gibberish ?

@Brandan Could you share how you built the ground mount and components used ?

@joe9000 are you sure you should be doing this?

Can you post pictures of the damage? If you can accees the area below the roof check for ponded water

Victron ?

Do you need a 4000w inverter?

One other option (which may not work for you!) is to keep the shed system off grid

@SeaGal has made a lot of good points, I suppose capacity will depend on how many panels the OP installs

"servers & networking equipment consuming ~1kW on average." This jumped out, what on earth have you got that uses that much? (and why) (coming from an IT guy with lots of kit)

Self heating comes with caveats: "Automatic Self-Heating Function: It will be auto-activated by the BMS when the battery is connected to a charger at -20℃to 5℃, will be stopped when the temperature has reached 10℃, and then the battery will be normally charged."

@ADDvanced why do you keep dropping the F bomb ? Do you think it makes people want to help ?

Manufacturers need to be more helpful They could like Victron say here are some settings for different batteries , if you dont have those use these

"Start At €4.499,00"

I vote DIY as well :) Have a look at these for a battery: https://www.fogstar.co.uk/collections/lithium-leisure-battery/products/fogstar-drift-230ah-leisure-battery

Think a 10KW inverter is pretty niche! Vast majority are 3.6 and 5's

Have you got a multimeter?

Worth repeating

Have you thought about using ESS? - it will give you a lot of control

I'm guessing that as well, just want to make sure it can be done in the window provided

I know you have solar panels, the question still stands - how will you charge battery (when there is no sun!)

Cost ? Do you need that much battery? How will you charge it ?

Changes to FIT equipment You also need to watch the DNO limits for generation very carefully
