• When on grid the AC coupled inverter will always be on and the power it produces will
be sold back to the grid. Limited To Home mode will not function with AC coupled PV
arrays.
• Grid Setup
o Limiter
▪ Grid Sell: maximum watts sold to grid
▪ Limited To Home: Limits power produced by the system
to match the demand of the home
▪ Limited To Load: Limits power produced by the system to
match the demand of connected loads
▪ Time Of Use:
• Time: When the system will sell batt/PV power to
the grid or home
• Power(W): Max watts to be sold from the battery only at each time
• Batt: The battery voltage or % at which the system will limit selling to the grid or home
from the battery. The system will drain the battery until that percent/voltage is reached.
• Charge: Enables grid/gen charging during a selected period up to the voltage or
percentage specified on the line. PV will always charge to 100%. If using a generator, the
charge box must be selected for the times that the generator may be needed, and the
gen will charge the battery to the Voltage of percentage specified in the “Batt” column.
• The sell check box allows the battery to be discharged for grid sellback for that time slot
• For Examples: See Pages 39-40
▪ Note: This mode requires Grid sell / limited to home / peak shaving be enabled.
▪ Note: If you need the batteries to never charge from the grid, uncheck the “Grid Charge” box
under the charge tab of the battery menu (see page 31).
o Sell Control
▪ General Standard: uses Protect Parameters in table
▪ UL 1741 & IEEE1547: Enables sell compliant functionality
▪ UL1741SA: Enables wider Freq, Voltage, and Power Factor
▪ GEN connect to Grid Input: Must be set if Generator is
connected to AC Grid breaker
o Grid Input
▪ Grid Frequency: Select the frequency of the grid
connected to the system
▪ Grid Type:
• 220V Single Phase (Call us before using)
• 120/240 Split Phase (North America)
• 120/208V 3 Phase
• Note: If 120/208V, the L1 and L2 are phase
specific. So, you may have to swap Grid L1 L2 for
208V applications.
• Note: Inverter power cycle is required each time
the input/output voltage is changed
▪ Protect Parameters (when
• Settings when the system will connect/disconnect from grid
• This is not used when UL 1741 & IEEE1547 is enabled
