Digital display
shows E04 and
alarm sounds. The appliance
connected to the AC
socket (or DC socket)
exceeds the capability
of the Powerpack
Solar 400. Unplug the appliance and confirm
that the appliance’s power
requirement is 320 W or less (144 W
or less) before attempting to restart
the appliance.
Digital display
shows E05 and
alarm sounds. The appliance
connected to the AC
socket has a short
circuit. Unplug and check the appliance.
Digital display
shows E07 and
alarm sounds. Internal battery
voltage falls below the
operational voltage
capacity. Unplug all appliances and start
recharging the Powerpack Solar 400.
Measured AC
output voltage
is too low. Use of an
average-reading AC
voltmeter to read
output voltage.
Internal battery is
almost fully
discharged.
The modified sine wave (MSW)
output of the Powerpack Solar 400
requires a true RMS reading meter,
such as the Fluke 87 series, for
accurate measurement.
A typical reading on a non-true RMS
meter should show between 98 Vac
to 120 Vac.
Verify battery status and recharge the
Powerpack Solar 400 as necessary.
“Battery Charge %” reading on the
digital display is only accurate when
the Powerpack Solar 400 has been
disconnected from all appliances and
all charging sources for 15 minutes.
