(Initial setting)
Power Assist Function is enabled.
C1-06: Power Assist Level
This setting is a special setting for power assist mode when the Stackable Inverter is
charging and due to a sudden load, the AC IN current exceeds the AC IN Current Limit
(B2-05), the Stackable Inverter will switch to power assist mode (when C1-05=1)
At that moment, the current need is unknown. The Stackable Inverter makes an assumption
of the magnitude of this current. This assumption is equal to AC IN Current Limit (B2-05)
multiplied by this Power Assist Level (C1-06). The default factor is two.
This will prevent the circuit breaker from tripping because current provided by the
INVERTER minus the current drawn by the load is always lower than the rating of the
circuit breaker. This happens, of course, when the AC IN Current Limit (B2-05) is correctly
adjusted to the circuit breaker.
If for instance in a generator application, the circuit breaker has a higher value than the AC
IN Current Limit (B2-05)(Normal load of generator is lower than maximum peak load) and
one knows that the load which is switched on always draws a certain current, one can
consider to increase this factor (C1-06) to achieve better results with sudden load changes.
