3.0 – Pre-Installation

The information within this section covers pre-installation procedures & considerations, namely, PHI 3.5

Battery performance parameters to be aware of during the design process, guidance on system sizing, as

well as installation site requirements and pad mounting.

3.1 – PHI 3.5 Battery Performance Parameters and

Sizing Calculations

The PHI 3.5 Batteries within the OutBack AccESS are designed to operate at a continuous C/2 rate across

a large operating temperature range, as seen in Table 1.0 above. The SimpliPhi AccESS needs no increase

in sizing and no special compensations when determining the size of the energy storage and management

system under the circumstances and conditions seen in Table 1.0 above. Each AccESS unit comes pre-

programmed to maximize the performance of the PHI 3.5 Battery bank.

PHI 3.5 Batteries within the AccESS unit do not need to be de-rated unless running continuously at more

than 90% capacity, at temperatures below 0° C, or above 49° C. To achieve higher, warrantied cycles of

10,000+, the PHI 3.5 Batteries are typically operated at 80% maximum Depth of Discharge. The AccESS

comes pre-programmed for 80% depth of discharge. Please contact SimpliPhi Power Technical Support if

alternative settings are desired. Please also refer to operating temperatures and inverter settings in

Programming section.

3.1.1 – Design Parameters: Maximum Sizing Guidelines

Below are the maximum sizing guidelines for installations of the AccESS:

• Maximum AC input = 25A at 240 Vac

• Maximum DC coupled PV array = 8 kW DC

• Maximum AccESS units combined in parallel: 2 Units = 16 kW AC

3.2 – System Sizing for Your Installation

The number of PHI 3.5 Batteries within the AccESS unit should be specified in terms of total storage

capacity before the initial installation based on the goals and objectives of the project. All PHI 3.5

Batteries are balanced during final production and testing stages. Following proper wiring guidelines

ensures that a system will not require any manual balancing processes.

CAUTION:

Do not combine PHI 3.5 Batteries with other brands or chemistries. This will void the Warranty.

CAUTION:

Do not mix PHI 3.5 Batteries from different installations, clients or job sites. This will void the

Warranty.
