FYI The 12 and 15kw both have dual lugs on positive and negative battery inputs.

I was thinking the Midnite combiner, but it's a very big product for what we're trying to accomplish. I was hoping Polaris type tap connectors might be able to do it. I think this application is going to require a somewhere around 800A calculated minimum circuit ampacity. I'm not quite certain how to calculate the required ampacity properly for this bus. Either way, I would need to find a connector that accepts fine stranded cable. Such an animal might not exist in the required ampacity. The Ilsco PBTS line accepts find stranded cable, and if you stagger inputs and outputs it is my understanding that the ampacity allowance is additive. The 600 MCM 4-port connectors might have the required ampacity. Maybe I'm dreaming and a Polaris-type connector isn't an easy way out.
Alternatively, I was thinking of a Blue Sea 1000A busbar mounted in a trough or junction box. Jason Szumlanski Principal Solar Designer | Florida Solar Design Group

Subject: [RE-wrenches] Parallel Homegrid Stack'd Busbar I'm doing my first installation with two 24 kWh Homegrid stacks. They will feed two Sol-Ark 15k. I'm seeking recommendations on busbars for connecting this up in the most elegant way possible. Pictures speak 1,000 words, so if you have any I would appreciate it (off-list is fine).
