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 “5” switch (see Figure 4.1 – (5)) on the bot-
tom 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 installation.
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 operating data as well as error mes-
sages 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.
4.8 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.
IMPORTANT
Due to measuring tolerances, the measured va-
lues 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 opera-
ting conditions this deviation is minimal.
