– Inverter overload
– Periodic test run
(*) The value measured here will be the total AC
consumption of the system.
Condition-parameters are prioritized in the order
shown above. When a number of conditions are
reached at the same time, only the highest-priority
condition will be shown as active. All enabled
conditions will be evaluated - even if the generator is
already running. When the active condition has been
satisfied, an un-met parameter in a lower-priority
condition will keep the generator running.
Relays triggered by Battery SOC
– Use Battery SOC value to start/stop: Toggle this
feature on or off.
– Start when Battery SOC is lower than: Set the
depletion level for auto-start.
– Start value during quiet hours: During Quiet hours
it may be desirable to delay an auto-start until it
really can't be avoided. If Quiet hours has been
defined, set a lower, more critical, autostart level.
– Stop when Battery SOC is higher than: Set the
recharge level for auto-stop.
– Stop value during quiet hours: If Quiet hours has
been defined, set a lower auto-stop level to
achieve a shorter generator run-time.
Relays triggered by Battery Current
– Use Battery current value to start/stop: Toggle this
feature on or off.
– Start when Battery current is higher than: When a
high AC demand is experienced which will soon
exhaust the battery, the generator can be auto-
started to assist in meeting that demand. Set the
current-level at which this will occur.
– Start value during quiet hours: If Quiet hours has
been defined, set a higher, more critical current
value.
– Start after condition is reached for: Set a delay
before auto-start. Some AC device will draw a
short-term, high-peak current on start-up.
Instigating a delay before auto-start will avoid
starting the generator unnecessarily.
– Stop when battery current is lower than: Set the
current for auto-stop.
– Stop value during quiet hours: If Quiet hours has
been defined, set a higher current level to achieve
shorter generator run-times.
– Stop after condition is reached for: Set a delay to
ensure that the current-reduction condition is
stable.
Relays triggered by Battery Voltage
1 Toggle the feature on or off.
2 When battery voltage falls below the value
entered the relay will start the generator.
3 If Quiet hours has been defined enter a lower
(more critical) value to ensure the generator
will only auto-start when absolutely
necessary.
4 This function allows the user to build-in a
delay between the auto-start condition being
met and an auto-start being triggered. The
importance of this is that a sudden but
temporary high AC demand will cause an
equally sudden drop in battery voltage. This
drop may be temporary - in which case a
generator start is not required.
But if the condition endures for a longer period
of time than the value entered here, the
generator will be started.
5 When battery voltage rises above the value
entered the relay will stop the generator.
6 During Quiet hours it may be desirable to auto-
stop the generator sooner. Enter a lower
battery voltage value than the one above.
