Solar Panel
LOCATION
The solar panel should oriented as much as possible toward
the midday sun. Locate where there is no significant shading
of the solar panel. The Solar Charge Controller and Sealed
Lead Acid (SLA) battery should be located in close physical
and thermal proximity. Both must be shaded from direct
sunlight to minimize temperature differences between them
which will greatly diminish the battery service life. Also insulate
the bottom of the battery if heat could be absorbed from the
surface (concrete, metal etc.) on which the battery is resting.
Also take measures to prevent accumulation of moisture (rain,
snow, ice, flooding) between the battery terminals which could
discharge the battery. If the battery and Solar Charge Controller are housed in an
enclosure, the outside must be white or shiny metallic to mini-
mize solar heat build up inside that is seriously detrimental
to the service life of the battery. Even light colors (such as the
standard ANSI 61 Gray) can elevate the interior of the enclosure
by 40F (22C.) If other colors are used, the enclosure must be
shaded from direct sunlight or painted glossy white. In addition,
because even sealed batteries could vent if the Solar Charge
Controller fails, for safety reasons the enclosure should be
vented, particularly if it contains other electrical equipment.

For powering Seametrics mechanical meters along with dis-
play electronics, use a 12V Sealed Lead Acid (SLA) deep-cycle
battery with a minimum capacity of 22 Amp-hours. This should
provide a conservative 40 day backup with maximum battery
service life. Marine/RV grade deep-cycle batteries or automo-
tive batteries may be used but must be upsized in Amp-hour
capacity by two times and four times respectively to achieve
the same battery service life in most applications.
For powering Seametrics low power (<50mA) magnetic flow
meters (AG2000, WMP, WMX and low power EX-Series, etc.)
use only deep-cycle SLA batteries (not marine/RV or automo-
tive grade batteries) with a minimum capacity of 33 Amp-
hours. In climates where meters are operating in full pipe
mode much of the time with extended periods of cloudy days,
operating continuously through the year, or in latitudes above
50 degrees, the required battery Amp-hour capacity should
be reviewed before selection. To learn more, consult the Ap-
pendix in our solar power application note found at www.sea-
metrics.com.
In summary, the minimum recommended battery capacity, as
described above, will be adequate in most climates and ap-
plications. However, under marginal conditions, a larger ca-
pacity battery may provide superior reliability, better battery
service life and lower life-cycle costs.
