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 open batteries. Four charging voltages can be set with DIP switches.
Automatic equalisation charging
This setting is intended for tubular plate traction batteries. During absorption the voltage limit
increases to 2.83 V/cell (34 V for a 24 V battery) once the charge current has tapered down
to less than 10 % of the set maximum current.
Not adjustable with DIP switches.
See 'tubular plate traction battery charge curve' in VEConfigure.
Absorption time
The absortion time depends on the bulk time (adaptive charge curve), so that the battery is
optimally charged. If the 'fixed' charging characteristic is selected, the absorption time is fixed.
For most batteries, a maximum absorption time of eight hours is suitable. If an extra high
absorption voltage is selected for rapid charging (only possible for open, flooded batteries!),
four hours is preferable. With DIP switches, a time of eight or four hours can be set. For the
adaptive charge curve, this determines the maximum absorption time.
Storage voltage, Repeated Absorption Time, Absorption Repeat Interval
See Section 2. Not adjustable with DIP switches.
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 of 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 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.
