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 16 A.
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: 4,5 A.
(2,7 A 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.
