Generator (AC-in-1) / Shore current (AC-in-2)

These are the standard current limit settings at which PowerControl and
PowerAssist come into operation. See Section 2, the book 'Energy Unlimited',
or the many descriptions of this unique feature on our website
www.victronenergy.com .

UPS mode

If this setting is 'on' and AC on the input fails, the Quattro switches to inverter
operation practically without interruption. The Quattro can then be used as an
Uninterruptible Power Supply (UPS) for sensitive equipment such as
computers or communication systems.
The output voltage of some generators is too unstable and distorted for using
this setting* – the Quattro would continually switch to inverter operation. For
this reason, the setting can be turned off. The Quattro will then respond less
quickly to voltage deviations on AC-in-1 or AC-in-2. The switchover time to
inverter operation is consequently slightly longer, but most equipment
(computers, clocks or household equipment) is not adversely impacted.
Recommendation: Turn the UPS feature off if the Quattro fails to
synchronise, or continually switches back to inverter operation.
*In general, the UPS setting can be left 'on' if the Quattro is connected to a
generator with a 'synchronous AVR regulated alternator'.
The UPS mode should be set to 'off' if the Quattro 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, engine speed is
reduced when the load is low: This reduces noise, fuel consumption and
pollution. A disadvantage is that the output voltage will drop severely in the
event of a sudden load increase. More load can only be supplied after the
engine is up to speed.
When this setting is 'on', the Quattro 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.

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.
