Search Mode
Instead of the AES mode, the search mode can also be chosen (with help of
VEConfigure only).
If search mode is 'on', the power consumption in no-load operation is decreased by
approx. 70%. In this mode the MultiPlus, 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 factory settings are:
Shut down: 40 Watt (linear load)
Turn on: 100 Watt (linear load)
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.
In case a non-grounded output is required during inverter operation, this function can
be turned off with help of VEConfigure.
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.
Alternatively, 'Fixed' mode can be selected with DIP switches.
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 flooded flat-plate lead-acid batteries. Four charging voltages can
be set with DIP switches.
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.
