Yes it does. It's the "51.2V Vertical Battery Pack" with the 314 Ah EVE cells. I have two of them connected in parallel, communicating with my Sol-Ark 18k inverter via a standard Pylontech protocol for closed-loop communication. Maybe I confused you by describing it as a "wall mount"? The vertical batteries are very often wall mounted. I should have just said "vertical" instead. Anyway, they have been fantastic batteries. Two in parallel can discharge roughly 19kW of power continuously, which is more than enough to power all of the big loads in my home at the same time. The only downside of the batteries is you have to configure the JK BMS yourself. But there's a lot of community resources for that: https://docs.google.com/spreadsheets/d/1szaRxYzBHxwairtpCBBF...
