AES (Automatic Economy Switch)
Instead of the search mode, the AES mode can also be chosen (with help of VEConfigure
only).
If this setting is turned 'on', the power consumption in no-load operation and with low
loads is decreased by approx. 20%, by slightly 'narrowing' the sinusoidal voltage.
Not adjustable with DIP switches.
Applicable in stand-alone configuration only.
Ground relay (see appendix B)
With this relay (H), the neutral conductor of the AC output is grounded to the chassis
when the back feed safety relay is open. This ensures the correct operation of earth
leakage circuit breakers in the output.
If a non-grounded output is required during inverter operation, this function must be
turned off. (See also Section 4.5)
Not adjustable with DIP switches.
Battery charge curve
The standard setting is 'Four-stage adaptive with BatterySafe mode'. See Section 2 for a
description.
This is the recommended charge curve. See the help files in the software configuration
programs for other features.
Battery type
The standard setting is the most suitable for Victron Gel Deep Discharge, Gel Exide
A200, and tubular plate stationary batteries (OPzS). This setting can also be used for
many other batteries: e.g. Victron AGM Deep Discharge and other AGM batteries, and many
types of flat-plate open batteries. Four charging voltages can be set with DIP switches.
Automatic equalisation charging
This setting is intended for tubular plate traction batteries. During absorption the voltage limit
increases to 2,83V/cell (34V for a 24V battery) once the charge current has tapered down to
less than 10% of the set maximum current.
Not adjustable with DIP switches.
See 'tubular plate traction battery charge curve' in VEConfigure.
Absorption time
The absortion time depends on the bulk time (adaptive charge curve), so that the battery is
optimally charged. If the 'fixed' charging characteristic is selected, the absorption time is fixed.
For most batteries, a maximum absorption time of eight hours is suitable. If an extra high
absorption voltage is selected for rapid charging (only possible for open, flooded batteries!),
four hours is preferable. With DIP switches, a time of eight or four hours can be set. For the
adaptive charge curve, this determines the maximum absorption time.
Storage voltage, Repeated Absorption Time, Absorption Repeat Interval
See Section 2. Not adjustable with DIP switches.
