AC LINE: If the LED indicator of local power grid is on, that implies connection
with the power grid and that the status is normal. If the LED is flashing, it
implies a connection is made yet an abnormal status of the power grid occurs
(over voltage, under voltage or exceed stable voltage range).
AC CHARGE: If the LED indicator of local power grid charger is on, that
implies the built-in AC charger is charging a battery. If the LED is flashing, it
implies the AC input is available yet the AC charger is not operating.
PV CHARGE: If the LED indicator of Solar MPPT charging controller is on, that
implies the solar panels are charging to the battery bank through the MPPT
built in the PV inverter. If the LED is flashing, it implies the PV input is

available yet the PV controller is not operating.
INVERTER: If the LED indicator of inverter mode is on, that implies the PV
inverter is converting electricity from the battery bank to the AC output and
feed to the loads.
BY PASS: Bypass power indicator with the “ON” implying the local power grid
through the built-in relay in PV inverter is feeding the loading devices.
RUN: PV inverter's operating indicator with the “ON” implying the PV inverter
is started and at a normal operating status that it can supply an AC voltage to
the loading devices.
Min. ALM: PV inverter's warning indicator with the “ON” implying a warning
notice that to be handled without delay. There will be intermittent alarm go off
to remind the users despite the PV inverter can still supply output power to
loading devices.
Maj. ALM: PV inverter's malfunction indicator with the “ON” implying the PV
inverter cannot operate normally due to a fault that the user is required to
troubleshoot the issue immediately.
