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. 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 “New Advanced Features Setting” on page 12.
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 that is enough to abruptly
resume inverting. 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 “New Advanced Inverter Settings” on page 13.
LBCO Delay
LBCO Delay (LBCO Delay) is the amount of time in seconds before inverting is
interrupted due to low battery voltage.
See “New Advanced Inverter Settings” on page 13.

WARNING
BATTERY TYPE HAZARD
When using Lithium Ion batteries, ensure that the battery pack being used
includes a Battery Management System (BMS) with safety protocols.
Failure to follow these instructions can result in property damage, death
or serious injury.
