Search Mode
Instead of the AES mode, the search mode can also be chosen. If search mode is 'on', the power consumption in no-
load operation is decreased by approx. 70%. In this mode the product, when operating in inverter mode, is switched off in
case of no load or very low load, and switches on every two seconds for a short period. If the output current exceeds a
set level, the inverter will continue to operate. If not, the inverter will shut down again.
The Search Mode 'shut down' and 'remain on' load levels can be set with VEConfigure.
The default settings are:
Action
Threshold
Shut down
40 Watt (linear load)
Turn on
100 Watt (linear load)
Ground relay (see appendix B)
With this relay, the neutral conductor of the AC output is grounded to the chassis when the back feed safety relays are
open. This ensures the correct operation of earth leakage circuit breakers in the output. If required an external ground
relay can be connected (for a split-phase system with a separate autotransformer). See appendix A.
Battery charge algorithm
The standard setting is 'Four-stage adaptive with BatterySafe mode'.
This is the recommended charge algorithm for lead acid batteries. 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 flooded batteries.
With VEConfigure the charge algorithm can be adjusted to charge any battery type (Nickel Cadmium batteries, Lithium-
ion batteries)
Absorption time
In case of the standard setting 'Four-stage adaptive with BatterySafe mode' the absortion time depends on the bulk time
(adaptive charge curve), so that the battery is optimally charged.
10.2.1 Equalisation
Traction batteries require regular additional charging. In the equalisation mode, the product will charge with increased
voltage for one hour (4V for a 48V battery). The charging current is then limited to 1/4 of the set value.
Equalisation mode supplies a higher charging voltage than most DC consuming devices can cope with. These
devices must be disconnected before additional charging takes place.
Automatic equalisation charging
This setting is intended for flooded tubular plate traction or OPzS batteries. During absorption the voltage limit increases
to 2,83V/cell (68V for a 48V battery) once the charge current has tapered down to less than 10% of the set maximum
current.
See 'tubular plate traction battery charge curve' in VEConfigure.
Storage voltage, Repeated Absorption Time, Absorption Repeat Interval
See Appendix E.
Bulk Protection
When this setting is 'on', the bulk charging time is limited to 10 hours. A longer charging time could indicate a system
error (e.g. a battery cell short-circuit).
AC input current limit
These are the current limit settings for which PowerControl and PowerAssist come into operation.
PowerAssist setting range: from 5,3 A to 32 A.
Factory setting: the maximum value (32 A).
UPS feature
If this setting is 'on' and AC on the input fails, the product switches to inverter operation practically without interruption.
The output voltage of some small generator sets is too unstable and distorted for using this setting – the product would
continually switch to inverter operation. For this reason, the setting can be turned off. The product will then respond less
