(SCP) or Conext ComBox to engage a generator and can assist an inverter/charger
when output power demands are high.
Note: Refer to Section 4.5.2 regarding the additional required “either-or” interlocked
switch for AC Coupled systems that include a generator.
• Cellular Modem
Allows remote monitoring of the system without utilizing a land-based internet
connection.
3.0 – 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 AccESS (both AccESS 1.0 and AccESS 2.0) 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 3.8 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 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 / output OCPD = 60 A
• Maximum DC coupled PV array = 4.8 kW DC
• Maximum AC coupled PV array: 6.8 kW AC (4-battery AccESS unit) or 5.7 kW AC (3-battery
AccESS unit)
• Maximum AccESS units combined in parallel: None. The AccESS unit is designed as a single
stand-alone unit. Stacking more than one AccESS unit in a single system Voids the AccESS
Warranty.
