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).
