N (No) when the system does not export energy onto the grid, and/or
when the entire system is not composed of all OutBack devices networked
to each other via the HUB.
Y (Yes) when the system exports energy onto the grid and the entire
system is composed of OutBack devices (including a grid-interactive
OutBack inverter) networked to each other via the HUB.
Notes:
1. Setting the charge controller’s Absorb Voltage higher than inverter’s Absorb Voltage prioritizes charge controller charging over
inverter charging. If the system does not utilize an inverter/charger for battery charging from an AC power source, the Absorb
Voltage in the charge controller may be programmed to the same Absorb Voltages listed in Section 4.2 – Inverter Settings.
2. Refer to Section 1.3.1 – Absorb End Amps.
• Levels are typical @ 25°C and may need adjusting at temperature extremes.
• When performing rapid deep charge/discharge cycles the battery should be allowed to “rest” 15 minutes in between.
1.3.1 – Absorb End Amps
Ideally, the end of the PHI battery bank’s Absorb charging phase is indicated by a low current (2% of the
battery bank’s Amp-hour rating) rather than by its length of time in the Absorb stage. In scenarios where
the OutBack system contains a
single charge controller and no FLEX net DC (FNDC) device, this low-
current trigger can be programmed using the Absorb End Amps setting in the charge controller. In
scenarios where a FNDC is included in the OutBack system (there is more than one FM100 or for any
other reason), this low-current trigger is instead programmed via the FNDC’s Return Amps setting and
