Monitoring the PPM
Monitoring the PPM during the initial days of an installation is essential for
understanding whether sufficient power provision has been achieved. By following
the cyclical daily state of charge, it will become evident whether the solar energy
harvested throughout the day is sufficient to maintain the battery in a good state of
charge; it is also possible to obtain an approximate idea of the time for which the
power to the Certimus could be maintained if no solar energy were available.
In medium or long-term installations, the battery will support operation during poor
light conditions until better light conditions allow re-charging of the battery. The
location’s latitude and climate will restrict the operational possibilities for any given
rating of solar panel. If in doubt, seek local advice where possible.
The operation of the PPM can be monitored using the web interface of the Certimus
or by streaming data from the Certimus to a copy of Discovery.
5.1.1 Using the web interface
The condition of the Power Pack Module can be monitored on the "Power" tab of the
instrument’s web-page. For this tab to be present, the Certimus must have been
booted up with the PPM connected.
Note:
The current shown is the total current flowing into the PPM. If the
battery in the PPM is being charged, the current will be shown as positive.
If the connected Certimus is drawing more current than the charge input
can supply (or if there is no charging input) the current will be shown as
negative.
5.1.2 Using Discovery
The condition of the Power Pack Module can be monitored using live data streams
within the Güralp ‘Discovery’ application.
