Figure 4.7: Excerpt from the protocol of a transmission via the RS232 interface
The interface of the PC or laptop that is connected must
comply with the standard for RS232 interfaces. Some compu-
ter manufacturers do not fully adhere to the standard. In such
cases, problems may occur during data transmissions.
4.9 The RS485 interface
Powador inverters are also equipped with an RS485 interface
(see Installation Instructions, fi gure 6.7) in order to enable
remote monitoring of your photovoltaic installation. 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 especially rec-
ommended 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.
In addition, you can use the Powador link within your instal-
lation to bridge long distances between several inverters or
between an inverter and the Powador-proLOG by means of a
wireless radio transmission. Contact your installer if you wish
to integrate remote monitoring into your system.
4.10 Display
Inverters in the Powador xi series are equipped with a back-
lit LCD (see fi gure 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
The measured data for current and voltage istainted with
the specifi ed tolerances (see Installation Instructions).This
data is not suitable for measuring effi ciency or compiling
yield data.Its sole purpose is to monitor the basic opera-
tion 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 meter by up to 15 %.
