Relays triggered by AC load
AC load triggers work similarly to other triggers but
the feature is refined by a Measurement setting.
The Measurement setting is available on firmware
v2.0 and later and has three possible values:
Relays triggered by Inverter High temperature
– Start on high temperature warning: Toggle this
feature on or off.
– Start when warning is active for: Set a delay to
avoid temperature rises which are temporary,
caused by brief high AC demands.
– When warning is cleared stop after: Set a delay to
ensure that a reduction in inverter temperature -
usually caused by lower power demand - is stable.
Relays triggered by Inverter overload
– Start on overload warning: Toggle this feature on
or off.
– Start when warning is active for: Set a delay to
ensure that the inverter overload warning has not
been triggered by a high-demand of AC power of
only short duration.
– When warning is cleared stop after: Set a delay to
ensure that the reduction in AC power demand is
stable.
Automatic periodic ‘Test run’
This feature allows automatic generator starts, period-
ically, as a ‘test run’.
7 This feature builds in a delay before stopping 
the generator after the 'stop' value has been 
reached. This is to make sure that the voltage 
rise is stable.
1 Total consumption (default option)
2 Inverter total AC out
3 Inverter AC out highest phase
1 Set the interval between test runs.
2 The test will be skipped if during the test run 
interval the generator ran for at least as long as 
it would on a ‘test run’.
3 The ‘test run’ interval counter will start from 
the date entered here.
No test runs will be carried out until the date 
set here has been reached.
4 Time of day at which the generator ‘test run’ 
will commence.
5 Duration of the test.
6 Enabling this feature will cause the ‘test run’ 
to continue until the battery is fully charged - 
instead of for a fixed amount of time.
