WeakAC
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.
Not adjustable with DIP switches.
BoostFactor
Change this setting only after consulting with Victron Energy or with an engineer trained by
Victron Energy!
Not adjustable with DIP switches.
Programmable relay
By default, the programmable relay is set as an alarm relay, i.e. the relay will de-energise in
the event of an alarm or a pre-alarm (inverter almost too hot, ripple on the input almost too
high, battery voltage almost too low).
Not adjustable with DIP switches.
Near the connection terminals an LED illuminates when the relay is activated (refer to S, see
appendix A)
VEConfigure software
With VEConfigure software the relay can also be programmed for other purposes, for example
to provide a generator starting signal.
With VEConfigure, several other special application modes of operation can be programmed.
Example: A house or an office connected to the public mains, fitted with solar panels with
energy storage in batteries.
The batteries are used to prevent return delivery to the mains. During the day, redundant solar
energy is stored in batteries. This energy is used in the evenings and at night. An energy
shortfall is compensated by the mains. The MultiPlus converts the battery DC voltage to AC.
The power is always less than or equal to the power consumption, so that return delivery to
the mains does not occur. In the event of mains failure, the MultiPlus isolates the premises
from the mains, which become autonomous (self-sufficient). In this way, a solar energy
installation or a combined micro-scale heating and power plant can be economically used in
areas with an unreliable mains supply and/or financially unfavourable energy-return
conditions.
