No illuminated display presented when the Enecsys
gateway is powered on.
Replace the Enecsys gateway.
The Enecsys gateway does not connect to the inter-
net.
Check the Ethernet cable and router. Replace the
Enecsys gateway.
The Enecsys gateway shows 0 when the micro invert-
ers are installed.
Verify that the micro inverters been installed correctly.
Verify the AC connections have been made: the con-
nectors should snap lock together during connection.
Verify that no cabling has become pinched by the PV
modules.
If the installation is on a metal roof or on a roof with a
metal liner, has a repeater been installed?
The Enecsys gateway is not showing the correct num-
ber of installed micro inverters.
Check PV module / micro inverter connections.
Is there
sunlight on the modules? (During
the night the gateway will always show 0 unless a re-
peater or double repeater has been installed, in which
case the gateway will show 1 or as many repeaters as
there are in the installation).
