Procedure
AC-in-1 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 (PowerAssist 11A, PowerControl 6A)
off
off
on = 10A (PowerAssist 11A, PowerControl 10A)
off

off = 12A (2.8kVA at 230V)

on = 16A (3.7kVA at 230V)

off = 20A (4.6kVA at 230V)
on

on = 25A (5,7kVA at 230V)

off = 30A (6,9kVA at 230V)

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.
AC-in-2 can be set in two steps using DIP switch ds5 (default setting: 16A).
Procedure: set ds5 to the required value:
ds5
off = 16A
on = 30A
More than 30A: with VEConfigure software or Digital Multi Control Panel
5.5.1.2 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 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%).
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%.
5.5.1.3 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.
