Gen Exercise Cycle (Day & Time): Set a weekly Gen exercise schedule. (Day of the week/Time/Duration Length) 
Gen must have two-wire start connected to Sol-Ark. To disable the exercise, set the duration length to 0 min. 
Discharge 
Shutdown V: battery voltage at which the inverter will shut 
down (battery symbol on the home screen will turn red) 
Low Batt: Low battery voltage (battery symbol on the home 
screen will turn yellow) 
Restart: battery voltage at which AC output will resume  
Batt Resistance: used in % SOC batt calculations 
Batt Charge Efficiency: used in % SOC batt calculations 
Batt Empty V: sets reserve capacity and improves % SOC 
calculations. It is not Batt_I adjusted 
  (Recommendations: 45V for AGMs, 48V for Lithium Iron Phosphate)  
Smart Load (Gen Breaker) 
A.  This mode utilizes the Gen input connection as an output 
that only receives power when the battery exceeds a user-
programmable threshold.  
B.  Enable "Use gen input as load output" to power high 
power loads such as a water heater, irrigation pump, AC 
unit, pool pump, etc.  
Smart Load OFF Batt  
Battery voltage at which the Gen Load will stop receiving power 
Smart Load ON Batt 
Battery voltage at which the Gen Load will start receiving power  
Using Gen load for a water heater, we recommend that only one leg (120V) be connected to the bottom 
element. This significantly reduces the power consumption of the water heater while retaining core 
functionality (it will heat water, only slower). 
Solar Watts is for on Grid 
A.  The system waits to turn on smart load until enough PV power is produced (when on grid) 
AC Coupling Settings (" For AC Coupled Input" ) 
A.  To use the Gen input breaker as an AC coupled input, check the "For AC Coupled Input" box (this feature will 
also work with "Grid-Tied" Inverters) 
B.  The meaning of Smart Load OFF Batt and Smart Load ON Batt change in this mode 
Smart Load OFF Batt: The SOC at which the AC coupled 
inverter(s) are shut down when in off-grid mode 
90% recommended  
Smart Load ON Batt: The SOC at which the AC coupled 
inverter(s) are turned on when in off-grid mode 60%-80% 
recommended   
Gen Load is limited to 50A at 240V (Do not exceed!) 
Maximum combined input (AC+DC) = 16kW 
•  Best: 3kWAC + 13kWDC 
•  Good: 5kWAC + 11kWDC 
•  OK: 8kWAC + 8kWDC 
•  Poor: 9.6kWAC + 6.4kWDC
