It's less than $200 for 50 feet of 2/0 welding cable from Temco
Their out of red right now but I doubt it will be long.

My utility room contains my natural gas boiler which is part of a whole house hydronic system -- hot water tank and hot water is piped to each of the air handlers (three of them). It is a great heating system, but it means the boiler room is very hot.

In the same room is located my two main electrical panels (2 x 200 amp service). I am planning to put the Sol Ark 15k for one of my panels (critical loads). However, this room will be hot. It makes sense to keep the batteries in the same room, but I am concerned about temperature. This room is consistently 15 degrees warmer than the rest of the basement.

Would it make sense to locate the SolArk and batteries far from the main electrical panel in another room? Maybe I should find some way to vent the Solark and the batteries?

Mounting the Sol Ark and batteries in a room away from the main power distribution panel reduces the thermal impact on them. This ensures that the unit operates at relatively low temperatures. If it is necessary to install the Sol Ark and batteries in a relatively hot room, consider ventilation measures such as installing a fan or ventilator to ensure air circulation and lower temperatures

I am using 10 ft long 4/0 coming out of my Solark 12K. You probably should get this one - https://temcoindustrial.com/temco-wc0342-welding-cable-4-0-awg-50-ft-50-red-50-black/
You can buy it with the terminals on it so you don't have to by the crimping tool. Check around

For followup, I ended up putting the battery bank 15 feet from inverter. Straight line is only seven feet, but by following the wire trough and the wall and making sure I had three feet in front of the electrical panel and three feet from the gas boiler, I ended up turning the server rack sideways.

I use four 4/0 cables with 3/8 inch lug on the solark side and 5/16 lug on the victron lynx power in bus bar side from pv-cables in CA. I then used 2/0 from the Pytes battery with 1/4 inch lugs on battery side and 5/16 inch lugs on bus bar side. My bus bar is not located on the sides like the eg4 case, but rather it is on a sliding tray on top of the batteries but inside the server rack.

I can't really open and close the drawer easily, but if I take things apart, I can get access to the bus bar.

I ran some of the cable in a pvc conduit and placed the toroid as it exited the conduit. I needed every inch of the cable.

I am hoping heat will be fine. The advice from others to insulate the hot water pipeshas definitely helped

Where did you get those flat orange interconnect for your battery?

Pytes battery came with those orange bus bars. Each battery came with a pair so I have two left over. They are flexible which helps with different spacing.
