Additional Considerations
•
You can connect a Solar Panel directly to a Track Box, provided your panel meets
the solar cell requirements below, No additional electronics are required.
•
Make sure the solar panel is oriented for optimal performance. Be aware that output
power suffers greatly if the panel is not fully exposed to direct sunlight (even the
shade of a small branch could be enough to ruin your solar output power).
•
On a warm sunny day with >12h of sun, the internal batteries may allow for 24/7
operation.
•
For most installations, it is recommended to use AUTOSTANDBY during the night
when no solar power is generated. This way you should have sufficient battery in
reserve, even on overcast days.
•
If the battery reaches empty, the Track Box will automatically restart as soon as the
Solar Cell delivers sufficient power for operation again.
•
When placed in direct sun on hot days the Track Box may get too hot to charge (see
datasheet). In this case, it may make sense to use the Solar Panel to provide shade
for the Track Box.
•
In Solar Mode the read rate (how often the reader looks for transponders) will be
reduced by 50% if the solar power input is low AND the battery is less than 75%. If
either condition is not met, the Track Box will operate with the full read rate. This
feature will save battery allowing for longer battery life. This may have an impact on
races with high speed or high density but will have no noticeable difference for
general application.
Solar Cell Requirements:
•
17V nominal "12V" Panel class - see attached datasheet for more details
•
25V DC MAX Voltage at no load (WARNING, never apply more than 25V!)
•
min 10W (30W or 50W recommended)
