Enerdrive ePRO COMBI Owners Manual
1. Dual function level bar. Indicates the percentage of delivered output power in inverter mode (turns red if
more than nominal output power is being delivered to the load). In charger mode, this level bar indicates the
percentage of delivered charging current.
2. Mode indicators. Indicate the operating mode of the ePRO Combi, as well as the status of each different
mode (see explanation below) :
‘charger on’ LED
Off
:
not charging
On (green)
:
charging
On (blinking red)
:
error (see chapter 4.2.1)
On (red)
:
charger disabled
‘inverter on’ LED
Off
:
not inverting
On (green)
:
inverting or power boosting
On (blinking red)
:
error (see chapter 4.2.1)
On (red)
:
inverter disabled
‘AC in’ LED
Off
:
No AC input present, transfer switch open
On (blinking
green)
:
AC input present and within range, ePRO Combi is
synchronizing
On (green)
:
AC input approved, transfer switch closed
On (blinking red)
:
AC input present but out of range
On (red)
:
AC transfer switch disabled
3. Charge status bar. Gives a rough indication of the charging progress, see below :
LED 3a : 100% full (ready)
LED 3b : 80% full
LED 3c : 50% full
LED 3d : empty
4. Power on, off, charger only switch. See chapter 4.1 for more explanations.
4.2.1. ERROR INDICATIONS
When the mode indicator LEDs are blinking red, an error has been detected. Each mode indicator LED can
either blink red individually, or combined along with one or more other mode indicator LEDs. There are five
different error indications, each with their own blinking pattern :
One flash in a row
:
Battery related error (too low or too high battery voltage, too low or too high
battery temperature, too high battery ripple voltage, battery defect)
Two flashes in a row
:
AC overload error (AC load requires too much power from the inverter, AC output
short circuit)
Three flashes in a row :
High temperature error (ePRO Combi shuts down on high temperature)
