15.
The batteries will bulk charge to 56 VDC, will Absorb for approximately 0.5 hours (at slower rates of charge,
less absorb time may be observed), and will then rest at approximately 53.3 VDC. This condition would be
considered fully charged.
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, form factor, and model.
CAUTION:
Do not combine PHI Batteries with other brands or chemistries. This will Violate
the terms of the Warranty.
The following are instructions for expanding upon a SimpliPHI battery bank using SimpliPHI batteries.
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 (SimpliPHI
batteries charge to 56V and “rest” at approximately 52.5 - 53.5V after being taken off a charge).
2.
Disconnect Bank A from the system, by either
3.
Disconnecting all battery cables leading from Bank A’s batteries to the battery combiner box,
panelboard, or inverter’s power panel, OR
4.
Turning off the built-in breakers included in each of Bank A’s batteries
5.
Connect the additional batteries (Bank B) to the system, following all sizing, wiring instructions and
torque specifications outlined in previous sections of segment 4.0 in this manual.
6.
Check that the connected Balance of System (BoS) equipment settings (including charge rate) are
altered as a result of being networked to Bank B.
7.
Charge Bank B fully, making sure all loads are disconnected at the time of initial charge.
8.
Wire all Bank A batteries and Bank B batteries in parallel, adhering to the wiring methods outlined in
Sections 4.6 and 4.7 above.
9.
Ensure that DC Positive common bus and DC Negative common bus ratings are appropriate for the
new larger quantity of batteries in the bank.
10.
Remember to re-orient the networking connections as one long “daisy-chain” for the expanded battery
bank. This will involve unplugging the last terminator plug in the chain and reposition to the end of the
“daisy-chain” and reconnecting the battery-to-inverter communications cable and reviewing all
Inverter settings for accuracy.
11.
Review all Inverter settings for accuracy; new values for certain settings should automatically appear
as reflective of the larger, expanded battery bank.
