Note also that the quantity of PHI Batteries calculated from this sizing guide is the minimum requirement to

prevent over-discharge and over-charge from an instantaneous power perspective. The system may need more

PHI Batteries in the battery bank in order to meet the system’s energy requirement (the amount of power the

batteries must supply to the loads over time).

Refer to SimpliPhi’s online Battery Bank Sizing Estimator tool for assistance with sizing the PHI Battery Bank

according to connected loads and the desired number of days of autonomy:

CAUTION: Not all system discharge or charge characteristics can be mitigated via

programming. Under-sizing a PHI Battery bank relative to the system’s maximum discharge or

charge rate will destroy the PHI Batteries and Void the Warranty.

4.0 – Program Settings for PHI Batteries

4.1 – SkyBox Settings

Unlike most other equipment, the OutBack SkyBox has PHI battery-related settings pre-programmed into

versions 1.5.0 and later. Instead of programming custom settings into the equipment (as described in later sub-

sections of this Section 4.0 – Program Settings for PHI Batteries), simply select “SimpliPhi” from the dropdown

menu on the SkyBox’s Battery Configuration screen in order to maintain the PHI Battery warranty:

Refer to this linked SkyBox: Commissioning with Energy Storage video for further instruction:

4.2 – Inverter Settings (Non-SkyBox)

In order to maintain the PHI Battery Warranty, it is critical to ensure that the appropriate settings are

programmed in all system components. The settings outlined in the following section maintain a maximum 80%

Depth of Discharge (DoD) for the PHI batteries, thereby optimizing the performance and life of the PHI batteries.

Not all OutBack equipment includes all the below listed settings. Settings that are not explicitly listed below do

not directly pertain to the PHI batteries. Refer to the relevant OutBack manual for more detailed information on

any one of the listed settings.

OutBack equipment networked together via the HUB and with a MATE3s system controller can be programmed

via the MATE3s (instead of directly in the inverter/charger and/or charge controller). Video instructions for
