Operation mode

Description

LCD display

Standby mode / Power
saving mode

Note:

*Standby mode: The inverter
is not turned on yet but at this
time, the inverter can charge
battery without AC output.
*Power saving mode: If
enabled, the output of
inverter will be off when
connected load is pretty low
or not detected.

No output is supplied by
the unit but it still can
charge batteries.

Charging by utility and PV energy.

Charging by utility.

Charging by PV energy.

No charging.

Fault mode

Note:
*Fault mode: Errors are
caused by inside circuit error
or external reasons such as
over temperature, output short
circuited and so on.

PV energy and utility
can charge batteries.

Charging by utility and PV energy.

Charging by utility.

Charging by PV energy.

No charging.

Line Mode

The unit will provide output
power from the mains. It
will also charge the battery
at line mode.

Charging by PV energy
