AC input current limit AC-in-1 (generator) / AC-in-2 (shore/grid supply)

These are the current limit settings at which PowerControl and PowerAssist come into operation.

PowerAssist setting range:

- From 11A to 100A for input AC-in-1

- From 11A to 100A for input AC-in-2

Factory setting: 50A for AC1 and 16A for AC2.

In case of parallel units the range the minimum and maximum values have to be multiplied by the number of parallel units.

See Section 2, the book 'Energy Unlimited', or the many descriptions of this unique feature on our website

UPS feature

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 small generating sets 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.

Dynamic current limiter

Intended for generators, the AC voltage being generated by means of a static inverter (so-called ‘inverter’ generators). In these

generators, rotational speed 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 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 ‘classical’ 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.

Note: when WeakAC is on, the maximum charge current is reduced by approximately 20%.

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.

Three programmable relays

The Quattro is equipped with 3 programmable relays. The relays can be programmed for all kinds of other applications, for

example as a starter relay for a generating set. The default setting of the relay in postion I (see appendix A, upper right corner)

is ‘alarm’.

Not adjustable with DIP switches.

Two programmable analog/digital input/output ports

The Quattro is equipped with 2 analog/digital input/output ports.

These ports can be used for several purposes. One application is communication with the BMS of a lithium-ion battery.

Not adjustable with DIP switches.

Frequency shift

When solar inverters are connected to the output of a Multi or Quattro, the excess solar energy is used to recharge the

batteries. Once the absorption voltage is reached, the Multi or Quattro will shut down the solar inverter by shifting the output

frequency 1Hz (from 50Hz to 51Hz for example). Once battery voltage has dropped slightly, the frequency returns to normal

and the solar inverters will restart.

Not adjustable with DIP switches.

Built-in Battery Monitor (optional)

The ideal solution when Multi’s or Quattro’s are part of a hybrid system (diesel generator, inverter/chargers, storage battery,

and alternative energy). The built-in battery monitor can be set to start and stop the generator:

- Start at a preset % discharge level, and/or

- start (with a preset delay) at a preset battery voltage, and/or

- start (with a preset delay) at a preset load level.

- Stop at a preset battery voltage, or

- stop (with a preset delay) after the bulk charge phase has been completed, and/or

- stop (with a preset delay) at a preset load level.

Not adjustable with DIP switches.
