described in the
Envoy-S Installation and Operation Manual
. In addition, the solar circuit may need to be
rerouted to a location closer to the AC batteries. One solution is to install the AC Battery, the solar
production circuits and the Envoy-S Metered off a common panel board.
Ensure that Meters are Properly Configured
If the consumption and production metering are not configured and operating properly, the AC Battery will
not operate or will operate improperly. The Envoy-S Metered uses the consumption and production meter
readings to determine if the AC Battery should be charging or discharging. Confirm in Installer Toolkit that
the consumption and production metering are both
Enabled
. A check next to both production and
consumption metering verifies that the metering is enabled. Additional checks include:
a.
To check that the consumption meter is installed correctly, shut off both the solar production and AC
Battery circuits. The consumption meter reading should closely match the utility meter’s reported
power reading.
b.
If the consumption meter is installed and operating correctly, turn on the solar production circuits,
but leave the AC Battery circuit(s) off. The solar production reading should be positive.
c.
Turn on the AC Battery circuit(s). Note that the consumption readings are impacted by the battery
operation. AC Battery charging increases the consumption reading. Since a portion of the PV
production is used to charge the batteries, the home’s consumption will appear to increase during
charging. When the batteries are discharging, the consumption metering reports the load
consumption lower than actual.
If any of these checks show incorrect results, check the Envoy-S and CT wiring against the appropriate wiring
diagram in the
Envoy-S Installation and Operation Manual
Ensure that the Grid Profile and Rate Tariff are Set
Check that the
Grid Profile
has been set in Installer Toolkit. If needed, set the
Peak Start Time
and the
Time
of Use
rate tariff in Installer Toolkit to control the time of day that the batteries begin to discharge to feed
loads.
Enable Charging From and Discharging To the Grid
In the Installer Toolkit:
Enable
Allow discharging to grid,
for batteries to feed power to the grid
Enable
Allow charging from grid,
for batteries to be charged from the grid
Enable
force charge
, and set the time, to charge the batteries irrespective of other priorities.
Battery LED is Off or Flashing Red
If the AC Battery is not working correctly, perform the following steps. If the issue persists, contact Enphase

•
If the AC Battery LED is off or flashing red, turn off the breaker for the branch circuit, wait for at least
one minute, and turn it back on.
NOTE
: During a brownout or blackout, the AC Battery powers down automatically. This is
normal. When power is restored, it automatically starts up again.
