Whole home backup
with the IQ System Controller 3M
This is the preferred conguration for the backup of the main load
panel. This conguration supports up to 1 × 80 A breaker for PV and
up to 1 × 80 A breaker for the IQ Batteries. In addition, the third DER
port can be used with an additional 80 A breaker for either the
IQ Batteries or PV.
The microinverter ranges supported in this conguration are
IQ8, IQ7, or IQ6 Series.
Check for Compatibility.
NOTE: This conguration provides whole home backup since it is
back-feeding the meter main combo panel with all loads. The
IQ Meter Collar placed behind the meter performs the functionality
to isolate the grid and enables backup when the grid is down.
However, as shown in the gure below, the IQ Load Controller can
be used to shed heavy loads while o-grid if the battery power and
energy are insucient for such loads.
