The interface of the connected PC or laptop must comply
with the standard for RS232 interfaces. Some computer
manufacturers are not 100% compliant with this standard. In
these cases there may be problems during the data
transfer.
4.9
The RS485 Interface
To enable remote monitoring of your photovoltaic
installation, blueplanet xi-series inverters are additionally
equipped with an RS485 interface (Figure 4.).
This interface enables monitoring of several inverters at the
same time. The KACO proLOG accessory allows you to
receive your yield and operating data or error messages by
text message or e-mail. This monitoring option is especially
recommended in cases where you are unable to check the
functionality of your installation on-site at regular intervals,
i.e. if your home or office is too far away from the installation
site. Please contact your installer if you wish to integrate
remote monitoring in your system.
4.10 Display
The inverters of the blueplanet xi-series are equipped with
an illuminated LCD display (Figure 4.). This display shows
all measured values and data. In normal operation the
background illumination is de-activated. As soon as you
press one of the keys the background illumination will be
activated. If 10 seconds elapse without a key being pressed,
the background illumination will be switched off again.
During normal operation the current grid-feeding power is
shown on the display, if no key is pressed for a longer
period of time.
Using the operating keys (see section 4.4 ) the values and
data listed in Table 4-3 can be shown.

Message
Explanation
1
Display shown during the starting-up period (in the morning), after
a malfunction or prior to night shutdown. No grid feeding in this
mode of operation. The inverter waits until the voltage has
exceeded a value of 125 V. If this value is exceeded for longer
than 5 minutes the grid feeding will be started. An audible sound
is generated when the grid isolation relay is enabled
2
Existing voltage and current of the solar generator connected to
the inverter. Shown in volts and amps; voltage tolerance
3 %;
current tolerance
5% at rated power. Greater tolerances are
possible when smaller generator currents are displayed.
3
Actual grid voltage, grid current and power (measurement of the
phase into which power is delivered); displayed in volts, amps
and watts; voltage tolerance:
3%; current tolerance: 3 %.
4
Short-term peak grid feeding capacity of the day,
displayed in W. According to the regulations stipulated by the
Power companies, this peak capacity must not exceed 10 % of
the rated power of the inverter. However, the generator may be
dimensioned for higher capacities.

Important!
Due to measuring tolerances the
measured values may not always
correspond to the actual values. The
measuring sensors of the inverter
have been selected in a way to ensure
maximum solar yields.
Due to tolerances the yields displayed
on the inverter may deviate from the
values of your Utility Company’s grid-
feeding meter by up to 5% (at nominal
power – in addition to the utility meter
tolerance of
2%).
The read data for current and voltage
are subject to the indicated tolerances
(+- 3% to 5%) and are not suitable to
measure degrees of efficiency or yield
data.
These readings are merely used to
check the installation for its general
function and proper operation.
