Charging Current Limitation; Stand-Alone, Parallel, 2-3 Phase Operation - Victron energy Quattro 48/5000/70 Manual

Procedure: set the DIP switches to the required value:
ds8 ds7 ds6

Remark: Manufacturer-specified continuous power ratings for small
generators are sometimes inclined to be rather optimistic. In
that case, the current limit should be set to a much lower
value than would otherwise be required on the basis of
manufacturer-specified data.
AC-in-2 can be set in two steps using DIP switch ds5 (default setting: 30A).
Procedure: set ds5 to the required value:

off = 30A
on = 50A
5.5.1.3 Charging current limitation (default setting 75%)
For maximum battery life, a charging current of 10% to 20% of the capacity in
Ah should be applied.
Example: optimal charging current of a 24V/500Ah battery bank: 50A to
100A.
The temperature sensor supplied automatically adjusts the charging voltage
to the battery temperature.
If faster charging – and a subsequent higher current – is required:
- the temperature sensor supplied should be fitted to the battery, since fast
charging can lead to a considerable temperature rise of the battery bank. The
charging voltage is adapted to the higher temperature (i.e. lowered) by means
of the temperature sensor.
- the bulk charging time will sometimes be so short that a fixed absorption
time would be more satisfactory ('fixed' absorption time, see ds5, step 2).
Procedure
The battery charging current can be set in four steps, using DIP switches ds4
and ds3 (default setting: 75%).

5.5.1.4 Stand-alone, parallel, 2-3 phase operation

DIP switches ds2 and ds1 are reserved for the selection of stand-alone,
parallel, split phase or 3-phase operation
