Top-up Control
Top-up Control is typically configured in conjunction with another control mode.
When configuring Top-up control you are telling the Solar Relay how many total
minutes you want the load to run in a 24 period. If the run time of the load using
other control mechanisms did not reach this duration, the Top-up mode will
trigger and complete the running time.
In the example to the left you can see System
Override 1 is setup to be Export Control and
System Override 2 is our Top-up mode.
Between the hours of 7:00am and 7:00pm
the Solar relay will run in export control. The
number of minutes the load runs during this
time will change from day to day based on
the amount of exporting solar.
At 11pm the Solar Relay will start operating in
Top-up mode. The number of minutes
between the start and stop times on the Top-
up override represents the total number of
minutes we want the load to run for. In our
example there are 300 minutes between
11:00pm and 4:00am the next morning. This
tells the Solar Relay that we need a total of
300 running minutes for the entire day.
If we had a nice sunny day, and the total
number of run time minutes during the
Export Control mode was 300 minutes or
better, when we get to 11pm the Solar Relay
will not turn the load on.
If the day was not so great and the run time
minutes during Export Control mode was
only 200 minutes, when we get to 11pm the
Solar Relay will turn the load on and run it for
100 minutes.
