SYSTEM MONITORING<br />
Continuous system monitoring is recommended, or even essential,<br />
for obtaining the absolute maximum performance from<br />
your solar energy system at all times. <strong>Steca</strong> offers you a number<br />
of different system monitoring methods:<br />
local visualisation, remote querying or remote monitoring.<br />
Local visualisation is sufficient when the operator regularly<br />
checks the data on the display unit of the inverter or via a connected<br />
PC or Laptop.<br />
Remote system querying is more convenient. The internal data<br />
logger can display all system data via the HTML user interface.<br />
With the <strong>Steca</strong><strong>Grid</strong> Portal system data can be accessed online<br />
from anywhere. The data logger sends the system data to an<br />
external database. The operator can then log in to this database<br />
and not only analyse his or her data but can also compare the<br />
data with regional irradiance values. This thus provides the operator<br />
with an objective impression of the effectiveness of his or<br />
her <strong>PV</strong> system.<br />
The most professional method is remote monitoring via an external<br />
data logger: The data logger monitors the functions of<br />
the system components and reports faults. Beyond this it stores<br />
all relevant system data.<br />
