2.1 The flash sequence table
Your Phoenix inverter is equipped with a self-diagnosis system, to inform you about
the cause of inverter shut down.
In the table below you can find out what kind of flashing sequence belongs to which
error.

2.2 Troubleshooting guidelines
PROBLEM : Inverter is not working (LED OFF)
Possible cause :
Power switch in OFF position.
Poor contact between the inverter's
battery wires and the battery terminals.
Blown inverter fuse.
Very poor battery condition.
PROBLEM : 'Battery voltage too low or too high' error keeps on appearing
Possible cause :
Poor battery condition.
Poor connection or inadequate wiring
between battery and inverter,
resulting in too much voltage drop.
General failure in your electrical
system (in case of no direct battery
connection).

Remedy :
Push the power switch to the ON
position.
Clean battery terminals or inverter wire
contacts. Tighten battery terminal
screws.
The inverter has to be returned for
service.
Replace battery.
Remedy :
Replace battery or charge it first.
When extending the battery wires of the
inverter make sure you use the correct
wire gauge (≥ 1.5 times larger than the
fixed battery wires). It's not advisable to
extend the battery wires to more than 3
meters.
Check your electrical system or consult
an electrical engineer to check it for
you.
