The P2 SunRise is equipped with a self diagnostic system that automatically identifies a
large number of possible operation issues by itself and displays them on the LCD screen.
Therefore it is possible to quickly isolate technical issues, and to distinguish between
Service Codes related to the installation versus Service Codes which are internal to the
inverter. Whenever the self diagnostic system has identified a particular issue, the
respective Service Code is displayed on the LCD screen.

Designation Description
Repair
Er00
DC_BUS pre-charge
fails.
The P2 SunRise is in soft
start procedure, but the DC
Bus can not reach and
maintain anticipative
charging voltage.
Er03
Inverter voltage
abnormal.
The P2 SunRise output
voltage is abnormal.
Er07
DC_BUS over-
voltage.
Er08
DC_BUS under-
voltage.

side. This fault code is
displayed if the current in
the DC network is larger
than specified.
Er30

control board.
EEPROM data is wrong.
1. Disconnect ALL
PV (+) or PV (-).
2. Wait for few
seconds.
3. After the LCD
switches off,
reconnect and check
again.
4. If error code
keeps recurring,
contact your local
distributor.
