Storing the State of the Inverter Mode
You can enable or disable a feature called StoreInvState which, when enabled
remembers the state of the inverter mode prior to a power down (that is, when AC
and DC power sources are disconnected). When the Conext SW is powered up
again, the inverter mode reverts back to its prior state.
See “Advanced Features Menu” on page 4–36.
NoLoadVD
The No Load Voltage Derating (NoLoadVD) feature further reduces tare loss by
adjusting output voltage by +4%/-5% of nominal, over the full load range. That
means at 50% load, the output voltage is at nominal but 5% below nominal at no
load and up to 4% at full load. The feature results in slight increase on overall
operating efficiency but may result in visible flicker of incandescent or similar
lights during large sudden load changes.
See “Advanced Features Menu” on page 4–36.
Low Battery Cut Out Hysteresis
Low battery cut out (Low Batt Cut Out) (LBCO) preserves battery life by
stopping the inverter when battery voltage drops down to the LBCO value for a
few seconds (see LBCO Delay below), then battery charging commences. When
charging starts, the voltage level jumps a little but enough that inverting might
resume abruptly. Then, battery voltage goes down again and charging starts
abruptly. To prevent the inverter from switching abruptly between inverting and
charging, the LBCO Hysteresis value is added to the LBCO value to allow the
battery voltage to reach a sufficient energy capacity level before inverting
resumes. This feature contributes to battery health.
See “Advanced Features Menu” on page 4–36.
LBCO Delay
LBCO Delay (LBCO Delay) is the amount of time in seconds before inverting is
interrupted due to low battery voltage.
