Note: G2 generation. High-voltage battery platform at 80-480 V, so it pairs with Fox ESS HV stacks rather than a 48 V bank. European efficiency 95.70%, peak 97.08%. EPS delivers 4400 VA peak for 60 s with under 10 ms switchover. Grid input takes 34.9 A / 7680 VA. Parallels to 10 units, IP65, 22 kg. Each MPPT is capped at 6000 W no matter which model, so on the larger units the array has to be split reasonably evenly across the two inputs.
