Note: High-voltage battery platform - 85-480 V, not a 48 V bank, so it pairs with Fox ESS HV stacks rather than a standard low-voltage lithium. EPS output 8000 VA continuous and 10000 W peak for 60 s, switching over in under 10 ms. Grid input accepts 69.6 A / 16000 VA, which is what lets it pass a large load through while charging. Parallels to 10 units. IP65 for outdoor mounting. MPPT window 80-500 V, nominal DC operating point 360 V.
