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 systemโ€™s 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.
