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.
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.
60 PV voltage is too high for fee-
ding 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.
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 interrup-
ted, 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, there-
fore, not an operational fault on the part of the blueplanet inverter.
The minimum triggering levels are determined by applicable stan-
dards (e.g. VDE0126-1-1 or UL 1741), and the inverter must switch off if
the permitted values are exceeded.
