- 1. introduction
- 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 β 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-Arkβs capacitors when connecting the PHI Batteries for the first time (as described in the Sol-Ark Install Guide Ownerβs 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...

- Charge Example: ,π©-#π·π½.β₯,,π·π½-ππΎ.-π.πΓ,π©ππ-ππΎ..
- ο· AC Coupled Solar PV Array is rated at 8 kW
- ο· PHI 3.8 kWh-51.2Vnom battery has a maximum continuous charge rate of 1.92 kWDC
- ,π©-#π·π½.β₯,,π-ππΎ.-π.πΓ,π.ππ-ππΎ..=π.π
- 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 bankβs charge rate in a DC Coupled system can be limited via Sol-Ark programming (Max A Charge), consider the PHI battery bankβs maximum continuous charge rate in the systemβs design.
- Charge Example: ,π©-#π·π½.β₯,,π·π½-ππΎ.Γ,π°ππ-πππ.-,π©ππ-ππΎ..
- ο· DC Coupled Solar PV Array is rated at 8 kW
- ο· Sol-Ark PV-to-Battery efficiency is 97.5%
- ο· PHI 3.8 kWh-51.2Vnom battery has a maximum continuous charge rate of 1.92 kWDC
- ,π©-#π·π½.β₯,,π-ππΎ.Γ,π.πππ-πππ.-,π.ππ-ππΎ..=π.ππ
- 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 Γ 37.5 ADC) would prevent the over-charging of a battery bank that includes only 4 batteries...
- 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 consiste...

- 5. USE CASES & Application notes
- Sol-Ark equipment includes many advanced programming features and a variety of modes (more than one mode can be used simultaneously). This section of the Guide will outline the system programming and setup basics for common use cases. However, refer a...
- 6. SPECIFICATIONS & WARRANTY
- For your reference:
- ο· See PHI 3.8 kWh Specifications Sheet.
- ο· See PHI 2.9 kWh Specifications Sheet.
- ο· See PHI Battery 10 Year Limited Warranty.
- Failure to adhere to installation protocol will void the Warranty.
