. DC/AC switch
The inverters include a connection box with an internal DC/AC
disconnect switch, which allows for the inverter to be discon-
nected from the photovoltaic generator and the AC power grid
for service.
To disconnect the inverter from the photovoltaic generator,
turn the internal DC/AC disconnect switch on the right side
of the connection box from the ON (1) position to the OFF (0)
position (see Fig. 4.1).
The inverter is delivered with the internal DC/AC disconnect
switch in the OFF (0) position. The ON (1) position is pointing
up and the OFF (0) position is pointing toward the front.

. Night time start switch

The unit switches off in the evening as nightfall approaches.
The display is no longer shown. In order to retrieve the values
from the current day (daily yield, daily hours of operation and
max. grid-feed power) after the display switches off, the unit
can be activated during the night by pressing the start switch
on the right side of the connection box.
ACT ION
To do this, press the "5" switch (see Figure 4.1 – (5)) on
the right side of the connection box for approx. 5 seconds
until a display appears.
You can now scroll through the menu and retrieve the saved
values. If over one minute elapses without a key being pressed,
the unit switches off automatically once again.
The "Counter oper. hours ", "Total operating hours", "Counter
yield", and "Total yield" data are permanently saved and
totaled. This data remains in memory even if the inverter is
switched off for a long time. The daily yield, daily hours of
operation and the max. daily grid-feed power are available
until the following morning and are cleared when PV generator
voltage is present again.

. The RS5 interface
Blueplanet inverters are also equipped with an RS485 interface
in order to enable remote monitoring of your photovoltaic instal-
lation. Several inverters can be monitored over this interface
at the same time. Using the KACO proLOG, watchDOG
or other monitoring device you can receive yield and operat-
ing data as well as error messages by SMS (text message) or
e-mail. These monitoring options are especially recommended
for situations where you are unable to check the functionality
of the installation on-site at regular intervals, e.g. if you live
far away from the installation site. Contact your installer if you
wish to integrate remote monitoring into your system.

. Display

Inverters in the blueplanet series are equipped with a back-lit
LCD (see figure 4.1 – (1)) which displays measured values and
data.
In normal mode, the backlighting is switched off. As soon
as you press one of the keys, the backlighting is activated.
If approx. 1 minute elapses without a key being pressed,
it switches off once again.
NOTE
Calculating efficiency by measuring the current and voltage
values leads to unusable results due to the tolerances of the
measuring devices.
The sole purpose of these values is to monitor the basic
operation of the system.
IMPOR TANT
Due to measuring tolerances, the measured values may
not always correspond to the actual values. The inverter's
measuring elements have been selected to ensure maximum
solar yields.
Due to these tolerances, the daily yields displayed on the
inverter may deviate from the values on your supply grid
operator's grid-feed counter by up to 15%. At low power
operation the sensors within the unit are not as accurate as
when at higher power therefore long term operation may
cause this high deviation. Under normal operating conditions
this deviation is minimal.
