CAUTION: Remember that charging the batteries in sub-freezing conditions will Void the
Warranty.
14.
Battery charging may be accomplished via the inverter/charger using an AC power source such as the grid or a
generator, or via a charge controller using power from a connected solar PV array.
15.
The batteries will bulk charge to 54.4 VDC / 27.2 VDC / 13.6 VDC, will Absorb for 2 hours, and will then rest at
approximately 53.3 VDC / 26.7 VDC / 13.3 VDC. At this point in the charging cycle, these voltages (53.3V / 26.7V /
13.3v) are considered 100% SOC.
16.
Once the batteries are fully charged, turn on the inverter’s AC Output breaker and/or the breaker at the top of
your loads’ breaker panel.

Battery Bank Expansion
New SimpliPhi Batteries that are added to an existing SimpliPhi battery bank must be of the same nameplate
voltage and form factor. If higher capacity PHI batteries are added, such as PHI 3.8 to a bank of PHI 3.5, the
battery bank’s total energy capaci
ty for system sizing calculations is the sum of the original battery capacity
rating (3.5) multiplied by the new total number of PHI batteries. Therefore, the capacity rating of the
original 3.5 PHI batteries determines the capacity rating for the newer PHI 3.8 battery once installed with
the original battery bank. For example, a battery bank composed of two PHI 3.5 batteries and one PHI 3.8
battery has a total energy storage capacity for system sizing calculations of 10.5 kWh for the bank (3 X 3.5
kWh= 10.5 kWh total). In addition, the Warranty for the new, additional PHI 3.8 battery adopts the
Warranty and Warranty period for the original bank of PHI 3.5 batteries.
CAUTION: Do not combine PHI Batteries with other brands or chemistries. This will Void the
Warranty.
Consult SimpliPhi Power Technical Support if you wish to expand a SimpliPhi battery bank.
In addition to adhering to all other Installation Manual instructions, refer to the following guidelines when
expanding upon an existing SimpliPhi battery bank:
1.
Charge the existing battery
bank (“Bank A”) according to normal charging procedure (PHI batteries
charge to 54.4V / 27.2V / 13.6V and “rest” at approximately 52.5
- 53.5V / 26.1V - 26.7V / 13.1 -
13.3V after being taken off a charge).
2.
Disconnect Bank A from the system, by either
a.
Disconnecting all battery cables leading from Bank A’s batteries to the battery combiner box,
panelboard, or inverter’s power panel, OR
b.
Turning off the 80A breakers included in each of Bank A’s batteries
3.
Connect the additional batteries (Bank B) to the system, following all wiring instructions and torque
specifications outlined in previous sections of segment 4.0 in this manual.
4.
Modify the settings in the system’s inverter/charger(s) or charge controller(s), whichever dev
ice will
be used to initially charge Bank B.
a.
Adjust the charge rate in accordance with the number of batteries in Bank B
