Input frequency range accepted by the MultiPlus. The MultiPlus synchronises within this range with the AC input frequency. The
output frequency is then equal to the input frequency.
Adjustability: 45 – 65Hz; 45 – 55Hz; 55 – 65Hz
Input voltage range
Voltage range accepted by the MultiPlus. The MultiPlus synchronises within this range with the AC input voltage. The output
voltage is then equal to the input voltage.
Adjustability:
Lower limit: 180 - 230V
Upper limit: 230 - 270V
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 power (several devices in parallel)
create a split-phase system
create a 3-phase system.
The standard product settings are for standalone operation. For parallel, or three phase operation see section 4.4.5 and 4.4.6.
Search mode
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.
Search Mode can be set with a DIP switch.
Search Mode ‘shut down’ and ‘remain on’ load levels can be set with VEConfigure.
The standard settings are:
Shut down: 30 Watt (linear load)
Turn on: 60 Watt (linear load)
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.
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. (Use VEConfigure)
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 flooded 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 2,83V/cell (34V for a
24V battery) once the charge current has tapered down to less than 10% of the set maximum current.
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
