Solar power requirements are more complex to
determine. Power requirements depend upon estimated
time relays will be on, how many will be on, how many
opto buffered input status LED’s will be on (if any), and
how often the RF modem will be on and transmitting.
Some power can be saved by turning the input LED
indicators off via register 4826.
RF modem power during transmit can be significant.
Allow for 1.3 amperes at 12V. A packet transmit takes
about 2 seconds, so current draw will be this much for
that period of time.
APPLICATION PROGRAMS
The following program is in the Basic Demos directory.
Program “battery charger.bas” is a stub program. It is a
part of the main program. However, with little
modification is can be a stand alone program.
