▪ Absorption: Set value appropriate for the batteries connected to the system using chart (Page
15)
• Absorption will stop at 1% of the capacity of the battery bank and drop to float
• Ex: 400Ah battery would be 4A
▪ Equalization: Set value appropriate for the batteries
connected to the system using chart (Page 15)
▪ Days: period of time between equalization cycles
▪ Hours: period of time taken to equalize batteries
• Note if Hours = 0 system will not equalize the
batteries
▪ Gen Charge: uses the gen input of the system to charge
battery bank from an attached generator.
• Start V: voltage at which system will AutoStart a connected generator to charge the
battery bank
• Start percentage: Percent S.O.C at which system will AutoStart a connected generator to
charge the battery bank
• A: charge rate from the attached generator in Amps
o Note: size this value appropriately for your given generator size
▪ Grid Charge
• Start V: voltage at which system will charge the battery bank from the grid. If grid is on,
batteries will stay at float voltage.
• Start percentage: Percent S.O.C at which system will AutoStart a connected generator to
charge the battery bank
• A: charge rate from the grid in Amps
o Discharge
▪ Shutdown V: battery voltage at which the inverter will
shut down (batt symbol on home screen will turn red)
▪ Low Batt: Low battery voltage (batt symbol on 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
o Smart Load (Gen Load)
▪ This mode utilizes the Gen input connection as an output
which only receives power when the battery is above a
user programmable threshold.
▪ The Gen input breaker in the user area of the system
becomes an output to high power loads such as a water
heater, irrigation pump, ac unit, pool pump.
▪ Smart Load OFF Batt
• Battery voltage at which the Gen load will stop
being powered
▪ Smart Load ON Batt
• Battery voltage at which the gen load will start being powered
▪ Note: If using Gen load for a water heater, it is recommended 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).
▪ Note: Gen Load is limited to 40A at 240V (Do not exceed!)
