When On-Grid, the AC-coupled inverter will always be on, and the will sell any extra power back to the grid.
AC Coupled PV Arrays will not work WITHOUT grid sell enabled (while grid is available).
To use the LOAD breaker for AC coupling grid tied inverter(s)
i. You must select "For Micro Inverter Input"
ii. The Gen Breaker is not used (even though the GEN breaker is not physically being used for this mode, AC
coupling on the LOAD breaker prevents the use of the GEN breaker)
iii. Wire as show in the preceding example diagram labeled "Load side AC coupling example"
Some load-side AC coupling installs will require a line side tap instead of the 50A breaker shown in the
example diagram
Grid Setup
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 called 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 reaching that percent/voltage.
Charge: Enables grid/gen charging up to the voltage or percentage specified on the line during a selected period. PV
will always charge 100%. If using a generator, select the charge box for the times that may need the generator, and the
Gen will charge the battery to the voltage of percentage specified in the "Batt" column.
Sell: The sell check box allows the battery to be discharged for grid sell-back for that time slot
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: Enable if Generator connects to
the AC Grid breaker
Zero Export Power: Power drawn from the grid at all times
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.
