The PC, however, must also run continuously. Because of the
amount of energy used, this type of monitoring only makes
sense over limited periods, such as during a fault analysis. For
permanent monitoring, we recommend the optional accesso-
ries (see section 5).
4.9 The RS485 interface
Powador inverters are also equipped with an RS485 interface
in order to enable remote monitoring of your photovoltaic
system. Several inverters can be monitored over this interface
at the same time. Using the Powador-proLOG series, you can
receive yield and operating data as well as error messages by
SMS (text message) or e-mail. This monitoring option is espe-
cially recommended for situations where you are unable to
check the functionality of the system on-site at regular inter-
vals, e.g. if you live far away from the system site. In addition,
you can use the Powador-link within your system to bridge
long distances between several inverters or between an
inverter and the Powador-proLOG using wireless radio trans-
mission. Contact your installer if you wish to integrate remote
monitoring into your system.
4.10 Display
Inverters in the Powador series are equipped with a back-lit
LCD (see fi gure 4.1 - (1)) that displays measured values and
data.
In normal mode, the backlight is switched off. As soon as you
press one of the keys, the backlight is activated. If approxi-
mately 1 minute elapses without a key being pressed, it
switches off once again.

NOTE
Calculating effi ciency by measuring the current and volt-
age values leads to unusable results due to the tolerances
of the measuring units.
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 measur-
ing elements on the inverter 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 %.
