quickly to AC input voltage deviations. The switchover time to inverter operation is consequently slightly longer, but most
equipment (most computers, clocks or household equipment) is not adversely impacted.
Recommendation: Turn the UPS feature off if the product fails to synchronise, or continually switches back to inverter
operation.
Dynamic current limiter
Intended for generators, the AC voltage being generated by means of a static inverter (so-called 'inverter' generators). In
these generators, engine rpm is reduced in case of low load: this reduces noise, fuel consumption and pollution. A
disadvantage is that the output voltage will drop severely or even completely fail in the event of a sudden load increase.
More load can only be supplied after the engine is up to speed.
If this setting is 'on', the device will start supplying extra power at a low generator output level and gradually allow the
generator to supply more, until the set current limit is reached. This allows the generator engine to get up to speed.
This setting is also often used for 'classical' generators that respond slowly to sudden load variation.
Weak AC
Strong distortion of the input voltage can result in the charger hardly operating or not operating at all. If WeakAC is set,
the charger will also accept a strongly distorted voltage, at the cost of greater distortion of the input current.
Recommendation: Turn WeakAC on if the charger is hardly charging or not charging at all (which is quite rare!). Also
turn on the dynamic current limiter simultaneously, and reduce the maximum charging current to prevent overloading the
generator if necessary.
Note: when WeakAC is on, the maximum charge current is reduced by approximately 20%.
BoostFactor This value adjusts the PowerAssist behaviour. If you are experiencing issues with PowerAssist (e.g.
overload), please consult with a specialist trained by Victron Energy before attempting to modify.
Programmable relay
The device is equipped with multiple programmable relays. These relays can be programmed for all kinds of other
applications, for example as a starter relay for a generator.
Auxiliary AC output (AC-out-2)
Intended for non-critical loads and directly connected to the AC input. With current measurement circuit to enable
PowerAssist.
11. Configuring the Product
The following hardware is required:
Either
•
A
MK3-USB (VE.Bus to USB) interface
•
A connection to the internet and VRM account to use
Note that firmware updates require use of the MK3-USB and cannot be performed remotely.
11.1 VEConfigure PC software
Configuration of the product is performed with a tool called VEConfigure. It is essential to read the seperate
manual
and undertake
Victron training
11.2 VE.Bus Quick Configure Setup
VE.Bus Quick Configure Setup is a software program with which systems with a maximum of three Multis (parallel or
three phase operation) can be configured in a simple manner.
The software can be downloaded free of charge at www.victronenergy.com.
11.3 VE.Bus System Configurator
For configuring advanced applications and/or systems with four or more Multis, VE.Bus System Configurator software
must be used. The software can be downloaded free of charge at
12. Maintenance
The product does not require specific maintenance. It will suffice to check all connections once a year. Avoid moisture
and oil/soot/vapours, and keep the device clean.
