Victron energy MultiPlus 24/5000/120 Manuel page 18

Procedure
The AC input current limit can be set using DIP switches ds8, ds7 and ds6 (default setting: 50A).
Procedure: set the DIP switches to the required value:
ds8 ds7 ds6
off off off = 6,3A (1.4kVA at 230V)
off off on = 10A (2.3kVA at 230V)
off on off = 12A (2.8kVA at 230V)
off on on = 16A (3.7kVA at 230V)
on off off = 20A (4.6kVA at 230V)
on off on = 25A (5.7kVA at 230V)
on on off = 30A (6.9kVA at 230V)
on on on = 50A (11.5kVA at 230V)
More than 50A: with VEConfigure software
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.
5.5.1.2 AES (Automatic Economy Switch)
Procedure: set ds5 to the required value:
ds5
off = AES off
on = AES on
Note: The AES option is only effective if the unit is used 'stand alone'.
5.5.1.3 Battery charge current limitation (default setting 75%)
For maximum battery life, a charge current of 10% to 20% of the capacity in Ah should be applied.
Example: optimal charge current of a 24V/500Ah battery bank: 50A to 100A.
The temperature sensor supplied automatically adjusts the charge voltage to the battery temperature.
If faster charging – and a subsequent higher current – is required:
- The temperature sensor supplied should always be fitted, since fast charging can lead to a considerable temperature rise of the battery
bank. The charge voltage will be adapted to the higher temperature (i.e. lowered) by means of the temperature sensor.
- The bulk charge 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 charge current can be set in four steps, using DIP switches ds4 and ds3 (default setting: 75%).
ds4 ds3
off off = 25%
off on = 50%
on off = 75%
on on = 100%
Note: when WeakAC is on, the maximum charge current is reduced from 100% to approximately 80%.
5.5.1.4 DIP switches ds2 and ds1 are not used during step 1.
IMPORTANT NOTE:
If the last 3 digits of the Multi firmware is in the 100 range (so the firmware number is xxxx1xx (with x any numer)) then ds1 &
ds2 are used to set a Multi in stand-alone, parallel or three-phase. Please consult the appropriate manual.
