3. BATTERY BANK SIZING
AmpliPHI batteries should be sized according to the connected loads’ energy (kWh) and power (kW)
requirements. While as few as one (1) AmpliPHI battery may be paired with Sunny Island equipment without
voiding the battery warranty, consider that the AmpliPHI battery is rated according to the specifications in the
table below, and that without a backup AC power source, loads that exceed the battery bank’s total capacity or
power rating will result in the entire system shutting down.
AmpliPHI 3.8 -48V Battery
Rated kWh Capacity per Battery
3.8 kWh DC @ 100% DoD
3.04 kWh DC @ 80% DoD (recommended)
MAX Continuous Charge & Discharge Rate
37.5 Amps DC (1.9 kW DC)
*Multiply by the number of AmpliPHI batteries in the bank for total capacity and power ratings (these values scale
linearly).
4. PROGRAM SETTINGS FOR AMPLIPHI 3.8 BATTERIES
The AmpliPHI Battery automatically communicates many but not all the battery’s operating parameters to the
Sunny Island over the communications connection. Parameters that must be manually programmed into the
Sunny Island are
in red in Table 1 on the following page. In order to maintain the SimpliPhi Battery Warranty, it
is critical to confirm that the appropriate settings for the desired Warranty have been auto populated and/or
