The combination of all these settings should give you a battery protection program that should look something
like this…….
When you get up in the morning, before the solar panels are working at their best, the generator runs for an
hour or so while you are cooking, or heating the bathroom for the kids, and starts the day with a support charge
(see SoC Renewable Assist).
Then it shuts down during the day when you expect that the solar panels will be carrying the load; then it may
start again later that night when the night load is at its highest or if there has been a cloudy day and there hasn’t
been as much solar input as you would have expected.
Throughout the whole day there is always the lower Generator Lockout Override “safety net” level that will not
allow the batteries to get totally flat. An Accredited Installer can help you arrive at the most fuel efficient program
to suit your particular needs.
The above system of Generator Auto Start SoC Start and Stop levels prevents the
generator from charging the battery bank during the batteries least energy efficient
stage; the highest voltage with the least amount of absorbed amp hours. This
reduces the generator run time, saving fuel.
This type of system is called Partial SoC control. A battery system will perform
well in partial SoC conditions however it is desirable to periodically fully charge
a battery bank and bring the SoC to 100% by allowing the charger to complete
through to Float stage.
Referring to the section FOR 100% SoC, if Override Stop SoC is enabled then
during the Normal or Night Assist times, the generator will continue to run and
charge the batteries right through to Float stage. This will occur according to the
Occurs Every setting. In this example it occurs every 7 days.
