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 with DIP
switches.
AC input current limit
These are the current limit settings at which PowerControl and PowerAssist come into
operation. The factory setting is 12A.
See Section 2, the book 'Energy Unlimited', or the many descriptions of this unique feature on
our website www.victronenergy.com.
Remark: lowest allowable current setting for PowerAssist: 2,7A.
(2,7A per unit in case of parallel operation)
UPS feature
If this setting is 'on' and AC on the input fails, the MultiPlus switches to inverter operation
practically without interruption. The MultiPlus can therefore be used as an Uninterruptible
Power Supply (UPS) for sensitive equipment such as computers or communication systems.
The output voltage of some small generator sets is too unstable and distorted for using this
setting* – the MultiPlus would continually switch to inverter operation. For this reason, the
setting can be turned off. The MultiPlus will then respond less 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 MultiPlus fails to synchronise, or continually
switches back to inverter operation.
*In general, the UPS setting can be left 'on' if the MultiPlus is connected to a generator with a
'synchronous AVR regulated alternator'.
The UPS mode may have to be set to 'off' if the MultiPlus is connected to a generator with a
'synchronous capacitor regulated alternator' or an asynchronous alternator.
Dynamic current limiter
Intended for generators, the AC voltage being generated by means of a static inverter (so-
called 'inverter' generators). In these generators, rpm is down-controlled if the load is low: 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 MultiPlus 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 'classic' generators that respond slowly to sudden load
variation.
