Operation
Low and High Battery Limits
Max SoC (%)
: After reaching maximum SoC (state of charge, the charger turns off. Setting it
to less than 100% could result in the battery becoming undercharged. See page 53 for more
discussion of SoC.
Min SoC (%)
: This selection is the lowest operating point for all functions that discharge the
batteries. When the batteries reach
Min SoC (%)
, the inverter will begin a new charge cycle.

The system graphic under the STATUS view will show the system’s measured SoC. (See page 19.)

If no charging source is available, the inverter will remain inactive until a source becomes available.

Below this point is the reserve battery supply for inverter basic functionality when no AC source is
present. This battery reserve is required to boot the inverter’s internal functions.
LBCO (V) : The LBCO ( L ow B attery C ut- O ut) function prevents the inverter from draining the
batteries completely.

When the DC voltage drops below LBCO (V) for the duration of LBCO delay (s) , the inverter will stop
functioning. The Battery tab will display a low battery message under Info , as will the EVENTS view.
See pages 19 and 27.

This function is intended to protect both the batteries and the inverter’s output. (Continuing to invert
on a low DC voltage may produce a distorted waveform.) The voltage and time are both adjustable.

Once loads are no longer supported at Min SOC (%) (see page 52), LBCO creates a reserve or
"buffer" against the inverter’s own battery drain. It should be set below the Min SOC (%) point to
avoid overlap. In the Custom Lead Acid battery selection used in this book, the setting is 44 Vdc.
However, this item should be carefully set according to the battery manufacturer’s instructions.
LBCI (V) : LBCI ( L ow B attery C ut- I n) is the recovery point from LBCO.

When the DC voltage rises above LBCI (V) for 10 seconds, the condition will clear and the inverter
will resume functioning. The voltage is adjustable. The time delay is not adjustable.

Connecting an AC source for the inverter to charge the batteries will also clear this condition.
HBCO (V) : HBCO ( H igh B attery C ut- O ut) prevents operation at excessively high voltage.

When the DC voltage rises above HBCO (V) for the duration of HBCO time delay , the inverter will
stop functioning. The Battery tab will display a high battery message under Info , as will the EVENTS
view. See pages 19 and 27.

This function is intended to protect the inverter’s output and loads. Continuing to invert on a high DC
voltage may produce a distorted waveform. The voltage and time are both adjustable.

Note that the HBCO function does not alleviate the high battery state. The cause is an external
condition which could damage the inverter.
HBCI (V) : LBCI ( H igh B attery C ut- I n) is the recovery point from HBCO.

When the DC voltage drops below HBCI (V) for 10 seconds, the fault will clear and the inverter will
resume functioning. The voltage is adjustable. The time delay is not adjustable.
