Victron energy BLUE POWER EasyPlus 12 Manuel page 21

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 12 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: 2,7 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 EasyPlus switches to inverter operation practically
without interruption. The EasyPlus 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 EasyPlus would continually switch to inverter operation. For this reason, the setting can be
turned off. The EasyPlus 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 EasyPlus fails to synchronise, or continually
switches back to inverter operation.
*In general, the UPS setting can be left 'on' if the EasyPlus is connected to a generator with a
'synchronous AVR regulated alternator'.
The UPS mode may have to be set to 'off' if the EasyPlus 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 EasyPlus 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.
