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 bat
teries 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.
