OutBack Power System GTFX/GVFX Grid-tie settings

In a GFX/GVFX Series Inverter/Charger, FLEXmax 80, HUB, and MATE installation set the FLEXmax 80 to GT mode in the ADVANCED MENU. GT mode allows the GFX/GVFX to manage the FLEXmax 80 float setting ensuring the FLEXmax 80 is always keeping the battery above the sell voltage of the GFX/GVFX.

Grid-tie applications (non-OutBack inverter/chargers)

When selling electricity back to the grid, keep the inverter Sell/Float voltage below the FLEXmax 80 float voltage. Appropriate values: 0.5 Volts difference for 24V battery system or 1.0 volt difference for 48V battery systems.

Positive grounded systems

Telcom applications frequently require a positive grounded system. The FLEXmax 80 switches the POSITIVE PV and battery leads. Keep these separate. If code allows, ground ONLY the battery positive lead in this case. Do not connect the FLEXmax 80’s battery plus to the PV plus input while the FLEXmax 80 is running. The OutBack HUB cannot be used in a positive grounded system.
