Hybrid-OGH MAX Series

MAX is the higher-capacity single-phase 48V line: INV-OGH-8.0KW-48V, 10.0KW-48V and 11KW-48V. It adds dual PV inputs / dual AC outputs, a 7-inch touchscreen HMI with RGB status, an external CT for 100% self-consumption, and parallel operation of up to 6 units for whole-home backup. Surge is 16,000–22,000VA with a 10–20ms transfer to pure sine output (93% peak efficiency).

Array power is up to 13,000W (6500W × 2 channels). MPPT range is 90–450VDC, max PV open-circuit voltage 500VDC, and max PV current 27A × 2 (40A peak). That is a much larger DC window than standard OGH, so it fits two long residential strings rather than a small off-grid array.

It is a 48VDC architecture (54VDC float) with up to 150A AC/total charge current. Match it to the Energy Storage Solution wall or stack mount (51.2V / 40–58.4V operating range) or to 24V LiFePO4 TB modules series-connected onto a 48V bus. USB / RS232 / Wi-Fi / dry contacts and OTA firmware are supported for monitoring.
