- 2. PHI battery bank-to-inverter connection
- Wire the PHI Battery bank to the Sol-Ark according to the PHI Battery Installation Manual, not according to the Sol-Ark Manual:
- Figure 1 โ Sol-Ark to Battery Connection
- It is acceptable but not required to use the ferrite choke on the positive and negative DC busbar-to-inverter leads (see Figure 1 above).
- SimpliPhi and Sol-Ark recommend against using the 100 Ohm resistor included with the Sol-Ark equipment to charge the Sol-Arkโs capacitors when connecting the PHI Batteries for the first time (as described in the Sol-Ark Install Guide Ownerโs Manual).
- Do not install the Battery Temperature Sensor. The PHI Batteries require no temperature compensation.
- 3. Battery bank sizing
- A properly sized PHI battery bank is sized to prevent over-discharge and over-charge from accompanying equipment. While the programming features of the Sol-Ark allow for battery discharging and charging according to specifically set parameters (refer ...
- Therefore, the PHI battery bank should still be sized to protect against over-discharge. In the case of an AC Coupled system setup, the PHI battery bank should also be sized to protect against over-charge from the solar photovoltaic (PV) array. In a D...

- A properly sized PHI battery bank based on the maximum charge from the AC Coupled solar PV array has a minimum of 6 batteries. This ensures that the battery bank does not over-charge from the AC Coupled solar PV.
- When comparing the same system using both the discharge and charge calculations for sizing the PHI battery bank, the minimum number of batteries in the bank should be the greater of the two results. For instance, when examining the discharge calculati...
- While the PHI battery bankโs charge rate in a DC Coupled system can be limited via Sol-Ark programming (Max A Charge), consider the PHI battery bankโs maximum continuous charge rate in the systemโs design.

A PHI battery bank utilizing the entire DC Coupled solar PV output potential has 5 batteries. However,
programming the
Max A Charge in the Sol-Ark to 150 A (4 ร 37.5 ADC) would prevent the over-charging of a
battery bank that includes only 4 batteries (refer to Section 4 of this Guide for complete programming details).
Homeowners with little to no loads on during the day (while solar power production is at its peak) might
consider sizing a larger PHI battery bank to take advantage of the entire solar PV output potential for battery
charging. Homeowners that consistently power loads during peak solar power production times may require a
smaller sized battery bank.
4. PROGRAM SETTINGS FOR PHI BATTERIES
In order to maintain the PHI Battery Warranty, it is critical that the appropriate settings for the desired
Warranty level are programmed in all system components. Failure to program the settings as described in this
Guide will void your Battery Warranty.
Depth of Discharge
To optimize the PHI batteriesโ and overall systemโs performance and life, SimpliPhi Power recommends
programming the equipment settings for an 80% maximum Depth of Discharge (DoD). Maintaining the PHI
battery at this DoD qualifies it for the 10-year / 10,000 cycle Warranty level. SimpliPhi warranties the PHI
battery for fewer cycles at greater DoD levels: 90% DoD is correlated with a 5,000-cycle Warranty and 100%
DoD correlates with a 3,500-cycle Warranty.
CAUTION: If a firmware update is executed on the Sol-Ark equipment, ALL the settings must
be reverified. The programmed settings shown in the following tables must be applied based
on desired Warranty/Cycle life. The recommended is 80% Depth of Discharge.
