Notes:
1. These settings are calculated by multiplying the per-battery value by the number of batteries in the connected
battery bank.
2. Max A Charge refers to the maximum charge rate from the solar PV array. Programming this value to the maximum
value versus the reduced-stress value does not impact the PHI Battery Warranty.
3. If the Auto Generator Start is utilized, the AGS is triggered when the batteries reach this set State of Charge (SoC)
percentage. Once triggered, the generator charges the batteries until they reach approximately 95% SoC, at which
point the generator turns off. This 95% SoC parameter is not programmable.
4. A refers to the maximum charge rate from the grid or the generator. If the Sol-Ark is connected to both the grid and
a standby generator, the Sol-Ark prioritizes the grid as the batteries’ charging source. Programming the
A value to
the maximum value versus the reduced-stress value does not impact the PHI Battery Warranty.
5. By default, battery charging from the solar PV array is prioritized over generator or grid charging.
6. When the battery has reached the Absorption voltage setpoint, the Sol-Ark utilizes constant-voltage regulation to
maintain the battery at the programmed Absorption voltage. The Absorption phase lasts until the batteries charge at
2% of the programmed Ah size. For example, one PHI 3.8-51.2V
nom
battery (rated at 75 Ah), will remain in the
Absorption charging phase until the number of Amps used to charge the battery decreases to 1.5 Amps DC (2% of
75Ah).
7. While the PHI Battery does not require an Equalization charge, programming Equalization to the voltage, frequency
and duration outlined in the table above ensures that the Sol-Ark’s internal SoC meter re-sets to 100% SoC every 30
days.
8. Smart Loads are no longer powered via solar and/or batteries when the batteries’ SoC level drops below this
programmed
Smart Load OFF Batt value.
9. Smart Loads are powered via solar and/or batteries when the batteries’ SoC level exceeds this programmed Smart
Load ON Batt value.
10. The Sol-Ark stops charging the batteries and powering the loads from the AC Coupled solar PV array once the
batteries’ SoC level reaches the
Smart Load OFF Batt value.
11. The Sol-Ark triggers the AC Coupled solar PV array to produce power (powering the loads and charging the
batteries) when the batteries’ SoC level exceeds this programmed
Smart Load ON Batt value.
CAUTION: When PHI battery quantities change, the capacity & charge/discharge current
settings must be reassessed. Failure to do so will void the Warranty.
Grid Setup
The Sol-Ark’s Grid Setup menu includes many advanced features (refer to Section 5 of this Guide). Regardless
of the features used, the PHI battery bank should never discharge more than its maximum continuous
discharge rate. Furthermore, to maintain the PHI batteries’ Warranty at a 10,000-cycle level, also do not
discharge the battery bank to a State of Charge (SoC) level less than 20%. These details are controlled in the
Grid Setup menu’s Limiter tab.
