Operating States
Status Explanation Comment
0 Inverter has just switched on Only for a brief period after being first switched on in the morning.
1 Waiting to start Grid parameters and generator voltage are checked.
2 Waiting to switch off Insufficient generator voltage and generator power. The status before it switches
over to night shutdown mode.
3 Constant voltage regulator The inverter continues to operate with minimum MPP voltage when the grid-feed
power is low.
5 Grid-feed mode The inverter is feeding into the grid.
8 Self test The line relay and the shutdown of the power electronics are tested prior to the
commencement of grid-feed mode.
9 Test mode For internal operation only.
11 Power limitation If the generator is producing too much power, the inverter limits to the max. power.
This can occur in the midday hours if the generator has been too largely dimensioned.
This is not a malfunction.
57 Waiting time after a fault After a fault, the inverter waits a defined country-specific amount of time before it
switches on (Installation Instructions, section 4, Technical Data).
60 PV voltage is too high for feeding into
the grid Protective function of the inverter. The inverter can only begin feeding into the
grid once the PV voltage falls below a specified value. The PV voltage is below the
maximum permissible no-load voltage, this status is not an error.
62 Standalone mode The inverter was switched to standalone mode by the blueplanet Grid-Save. function.
The inverter is disconnected from the public utility grid. The power indicator
percentage refers to the maximum AC power.
64 Output current limit The AC current is limited once the specified maximum value has been reached.

Fault signals
When these error messages are displayed, the grid-feed is
interrupted, the red LED (3) lights up, and the fault signal relay
has switched. This error correction takes a country-specific length
of time (see Installation Instructions, section 3, Technical Data).
Afterwards the red fault LED (3) goes out, the fault signal relay
drops out again, and the display signals that it is ready to feed
into the grid once again. Once the fault is gone, the blueplanet
inverter feeds in again.
Many of these fault signals point to a fault in the grid, and are,
therefore, not an operational fault on the part of the blueplanet
inverter. The minimum triggering levels are determined by applicable
standards (e.g. VDE0126-1-1 or UL 1741), and the inverter must
switch off if the permitted values are exceeded.
