Small Inverting
The inverter uses the small inverter when it is installed and the
option is enabled to improve efficiency. The default settings
are “Load Demand: ON” and 10 W to use the small inverter
and 75 W to switch to the large inverter. When the load falls
below 10 W there will be a 5-second delay (default setting)
before switching.
Normal Inverting
“Normal Inverting” is defined as inverting when the load
current is below the maximum (default setting) of 18.75 A
RMS
.
The inverter generates a constant voltage. 120 V
RMS
is the
default L1 to Neutral setting. If the current rises above 18.75
A
RMS,
then the inverter starts surging.
Surging
“Surging” occurs when the load current is above (default
setting) of 18.75 A
RMS
. For three seconds the inverter attempts
to generate a constant voltage at its default voltage setting. The
inverter will respond and shut down (depending on the load) as
shown in the diagram below.

Browning Out
“Brown out” occurs when the load current matches exactly the
(default setting) of 18.75 A
RMS
. The inverter will supply a
constant current while the output voltage falls. If it falls
