– Pre-Installation
The information within this section covers pre-installation procedures & considerations, namely, PHI 3.8
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 3.8 Battery Performance Parameters and
Sizing Calculations
The PHI 3.8 batteries within the Sol-Ark AccESS are designed to operate at a continuous discharge rate
of 7.6 kW
DC
(
AccESS Sol-Ark-8K-15.2 kWh model) or
11.4 kW
DC
(AccESS Sol-Ark-12K-22.8 kWh model)
across a large operating temperature range, as seen in Table 1.0 above. Neither SimpliPhi AccESS
model requires an increase in sizing nor any 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 3.8 battery
bank.
PHI 3.8 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 3.8 batteries are operated at 80% maximum Depth of Discharge (DOD). The AccESS
comes pre-programmed for 80% DOD. Please contact SimpliPhi Power Technical Support if alternative
settings are desired. Please also refer to operating temperatures and inverter settings in
this Manual’s
Programming section.
3.1.1
– Design Parameters: Maximum Sizing Guidelines
Below are the maximum sizing guidelines for installations of the AccESS:
•
Maximum AC Grid input / output OCPD = 50 A double-pole
•
Maximum DC coupled PV array =
◦
11 kW
DC
(AccESS Sol-Ark-8K-15.2 kWh model)
◦
16.5 kW
DC
(AccESS Sol-Ark-12K-22.8 kWh model)
•
Maximum AC coupled PV array =
◦
7 kW
AC
(AccESS Sol-Ark-8K-15.2 kWh model)
◦
7.6 kW
AC
(AccESS Sol-Ark-12K-22.8 kWh model)
•
Maximum AccESS units combined in parallel: None. The AccESS unit is designed as a single
stand-alone unit.
Stacking multiple AccESS Sol-Ark units will void the AccESS
Warranty
.
3.2
– System Sizing for Your Installation
The number of PHI 3.8 batteries within the AccESS unit should be specified in terms of total storage
capacity and instantaneous power rating before the initial installation based on the goals and objectives of
the project. All PHI 3.8 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 3.8 batteries with other brands or chemistries.
CAUTION:
Do not mix PHI 3.8 batteries from different installations, clients or job sites.
