is discharging to take the load, it will stop discharge when the SOC/Voltage is lower than this
limit.
• Off-Grid Cut-Off SOC(%)/Volt(V): When the inverter is not connected to the grid and the
battery is discharging to take the load, the battery will stop discharging when the SOC/Voltage
is lower than this limit.
Forced Discharge
• Forced Discharge Enable/Disable: If the customer wants to simply discharge the battery;
you can enable forced discharge function, and set both the discharge power and time period.
• Forced Discharge Power(kW): Forced discharge power limit.
• Stop Discharge SOC(%)/Volt(V): If Battery SOC is lower than this limit, the inverter will stop
forced discharging function.
• PVSellToGrid(Comp. w/ NEM3.0): Enable or disable PV sell back to grid feature.
• Forced Discharge Start Time 1-3: Start time for Forced Discharge.
• Forced Discharge End Time 1-3: End time for Forced Discharge.
Peak Shaving
• Grid Peak-Shaving: Peak-Shaving is used to avoiding peak demand charges from the grid.
Peak shaving can be accomplished by halting Grid Charging at specific times. For example, dur-
ing periods of peak demand (i.e., high grid rates), or when the batteries are near fully charged
based on SOC and Voltage. See Section 11.1.4 for more information regarding Peak-Shaving
settings.
• Grid Peak-Shaving Power(kW): Used to set the max. power that the inverter can draw from
the grid.
• Start Peak-Shaving Volt/SOC 1(V): The point at which Peak-Shaving starts.
• Start Peak-Shaving Volt/SOC 2(V): The point at which Peak-Shaving stops.
• Peak-Shaving Start Time 1-2: The time of day at which charging by the grid will be halted.
• Peak-Shaving End Time 1-2: The time of day at which charging by the grid will resume.
AC Couple
• AC Couple Enable/Disable: When there is an existing On-Grid PV inverter and you need the
18KPV system to function in both On-Grid and Off-Grid mode, you would connect the AC out-
put of the existing On-Grid PV inverter to the GEN terminal of the 18KPV and enable the AC
Couple function.
• AC Couple Start Volt(V)/SOC(%): AC Coupling will start at this set V/SOC.
• AC Couple Stop Volt(V)/SOC(%): AC Coupling will stop at this set V/SOC.
Smart Load
• Smart Load Enable/Disable: When Smart load function is enabled, the GEN terminal will be
reused to Smart Load, and the inverter will offer power to this load based on the setup values.
• Start PV Power (kW): This is the min. PV power limit to function with smart load output.
• On Grid Always On: Once this function is enabled, smart load will always function when grid
power is on.
• Smart Load Start SOC (%) / Volt (V): The high limit for battery to turn on smart load.
• Smart Load Stop SOC (%) / Volt (V): The low limit for battery to turn off smart load.
• Reset: Reset all settings to default.
