Input voltage range
Voltage range accepted. The product synchronises within this range with the AC input. The output voltage is then equal
to the input voltage.
Adjustability:
Lower limit: 180 – 230V
Upper limit: 230 – 270V
Note : the standard lower limit setting of 180V is intended for connection to a weak mains supply, or to a generator with
unstable AC output. This setting may result in a system shut down when connected to a 'brushless, self excited,
externally voltage regulated, synchronous AC generator' (synchronous AVR generator). Most generators rated at 10kVA
or more are synchronous AVR generators. The shut down is initiated when the generator is stopped and revs down while
the AVR simultaneously 'tries' to keep the output voltage of the generator at 230V.
The solution is to increase the lower limit setting to 210VAC (the output of AVR generators is generally very stable), or to
disconnect the product from the generator when a generator stop signal is given (with help of an AC contactor installed in
series with the generator).
Inverter voltage
Output voltage in battery operation.
Adjustability: 210 – 245V
Stand-alone / parallel operation / 2-3 phase setting
Using multiple 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 a single device in stand alone operation.
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 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)
