The LONGi label photo yields the exact model (LR4-60HPH-370M) and its electrical figures. The voltages nearly settle the DC/AC split on their own: ten panels in series reach 409 V, beyond the 250 V MPPT ceiling but inside the Fronius MPP window, while the MPPT tops out at five-panel strings. Fixed deck to MPPT as 2x5, sliding deck to Fronius as 1x10, one conductor pair through the flexible link.
