Inverter voltage
Output voltage of the MultiPlus in battery operation.
Adjustability: 210 – 245V
Stand-alone / parallel operation / 2-3 phase setting
Using several devices, it is possible to:
•
increase total inverter pow er (several devices in parallel)
•
create a split-phase system by stacking (only for MultiPlus units w ith 120V output voltage)
•
create a split-phase system w ith 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 sections 5.3 / 5.4 and
5.5.
AES (Automatic Economy Switch)
If this setting is turned 'on', the pow er consumption in no-load operation and w ith low loads is decreased by approx. 20%, by slightly
'narrow ing' the sinusoidal voltage. Applicable in stand-alone configuration only.
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 pow er consumption in no-load operation is decreased by approx. 70%. In this mode the MultiPlus, w hen
operating in inverter mode, is sw itched off in case of no load or very low load, and sw itches on every two seconds for a short period. If
the output current exceeds a set level, the inverter w ill continue to operate. If not, the inverter w ill shut dow n again.
The Search Mode "shut dow n" and "remain on" load levels can be set w ith VEConfigure.
The standard settings are:
Shut dow n: 40 Watt (linear load)
Turn on: 100 Watt (linear load)
Not adjustable w ith DIP sw itches. Applicable in stand-alone configuration only.
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 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 appendix A.
Not adjustable w ith DIP sw itches.
- Models w ith 50A transfer capacity only: if required an external ground relay can be connected (for a split-phase system
w ith a separate autotransformer).
See appendix A.
Battery charge curve
The standard setting is 'Four-stage adaptive w ith BatterySafe mode'. See Section 2 for a description.
This is the best charging characteristic. See the help files in the software configuration programs for other features.
'Fixed' mode can be selected w ith DIP sw itches.
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 w ith DIP sw itches.
With VEConfigure the charge curve can be adjusted to charge any battery type (Nickel Cadmium batteries, Lithium-ion batteries)
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
sw itches, a time of eight or four hours can be set. For the adaptive charge curve, this determines the maximum absorption time.
Autom atic equalisation charging
This setting is intended for flooded tubular plate traction or OPzS batteries. During absorption the voltage limit increases to 2,83V/cell
(34V for a 24V battery) once the charge current has tapered dow n to less than 10% of the set maximum current.
Not adjustable w ith DIP sw itches.
See 'tubular plate traction battery charge curve' in VEConfigure.
Storage voltage, Repeated Absorption Time, Absorption Repeat Interval
See Section 2. Not adjustable w ith DIP sw itches.
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). Not adjustable w ith DIP sw itches.
