Operation
4.6 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
at the bottom of the inverter.
ACTION
To do this, press the “4” switch (see Figure Figure 1 – (4))
on the bottom of the inverter 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.
4.7 The RS485 interface
Blueplanet inverters are also equipped with an RS485 interface
in order to enable remote monitoring of your photovoltaic ins-
tallation. Several inverters can be monitored over this interface
at the same time. Using the KACO pro
LOG, watchDOG
or other monitoring device you can receive yield and operating
data as well as error messages by SMS (text message) or e-mail.
These monitoring options are especially recommended for situ-
ations 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.
4.8 Display
Inverters in the blueplanet series are equipped with a back-lit
LCD (see fi gure Figure 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 effi ciency 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.
IMPORTANT
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 maxi-
mum 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.
