Inverter voltage
Output voltage of the MultiPlus-II in battery operation.
Adjustability: 210 – 245 V
Stand-alone / parallel operation / 2-3 phase setting
Using several devices, it is possible to:
• increase total inverter power (several devices in parallel)
• create a split-phase system with a separate autotransformer: see VE autotransformer datasheet and manual
• create a 3-phase system.
The standard product settings are for standalone operation. For parallel, three-phase or split phase operation see section 5.3.
AES (Automatic Economy Switch)
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. Applicable in stand-alone configuration only.
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 MultiPlus-II, 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 standard settings are:
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’. See Section 2 for a description.
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.
Automatic equalisation charging
This setting is intended for flooded tubular plate traction or OPzS 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.
Storage voltage, Repeated Absorption Time, Absorption Repeat Interval
See Section 2.
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:
12/3000/120-32
24/3000/70-32
48/3000/35-32
48/5000/70-50 48/8000/110 48/10000/140
PowerAssist setting range, grid in-line topology
4 A – 32 A
6 A – 50 A
11 A – 100 A
11 A – 100 A
PowerAssist setting range, grid parallel topology
with external current transformer
4 A – 50 A 6 A – 100 A 11 A – 100 A 11 A – 100 A
Factory setting: maximum grid in-line topology value.
