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.
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 2,83 V/cell (34 V for a 24 V 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.
