I'm spec'ing out a 5x8 cargo trailer build - for powering small concerts, festivals etc. Likely starting with a EG4 6500ex unit, with the possibility to add a 2nd unit in a few months for true split-phase/50a operation. For batteries - I'm in the debate of server-rack (EG4 or SOK likely) vs a wall-mount like the EG4 PowerPro - I'd like to have ~15kWh to start, and if/when I add a 2nd inverter I'd add more battery capacity accordingly.
I like the server rack option - as I could put them in a proper 19" rack with casters (a true heavy-duty road case, not the OEM ones they sell!), and wheel them in/out of the trailer for modularity, maintenance, storage or smaller events where I don't need the whole trailer etc. But that does seem like a larger footprint, vs strapping a PowerPro flush on a wall and keeping more floor space clear. But I'm also worried about the significant weight of the PowerPro mounted on a somewhat flexible cargo trailer wall and bouncing around down the road.
And relatedly - EG4 or SOK batteries? I'm assuming the LL/Pro versions as the communications & pre-charge circuit are useful to me. Since I don't plan to use an EG4 rack with the built-in bus bars - I don't like the small lugs, and this would limit paralleling units in shifting configurations (capacity, and physical layout). I can imagine occasionally using just 1 or 2 batteries for a smaller modular setup. The SOK terminals would give more flexibility here - but also seeing some reports about communications issues between EG4 inverters and SOK batteries.
Any feedback is helpful - thank you!
