Notes:
1) The factory defined battery type can be selected with the rotary switch next to VE.Direct
connector. The selected type will be shown here. The setting can alter between a factory
defined type and "USER".
2) These values can ONLY be changed for the battery type "USER". The values in the table
are for a 24V-battery.
3) Automatic equalisation can be set to "OFF" (default) or a number between 1 (every day)
and 250 (once every 250 days). See section 3.8 for more details about automatic
equalisation.
4) To allow the charger to equalise the battery properly, use the manual equalise option only
during absorbtion and float periods, and when there is sufficient sunlight. Press SELECT:
the text "" will blink, press SELECT again to start equalisation. To terminate the
equalisation mode prematurely, enter the setup menu and navigate to setup item 10, press
SELECT: the text "" will blink, press SELECT again to stop equalisation. The manual
equalise duration is 1 hour.
5) Relay function (setting 11):
Value
Description
0
Relay always off
1
Panel voltage high (setup items 16 and 17)
2
Internal temperature high (>85°C)
3
Battery voltage too low (setup items 12 and 13, default setting)
4
Equalization active
5
Error condition present
6
Internal temperature low (<-20°C)
7
Battery voltage too high (setup items 14 and 15)
8
Charger in float or storage
9
Day detection (panels irradiated)
10
Load control (relay switches according to load control mode, see setting 35 and
note 7)
6) The parameter BMS present will be set to 'Y'es internally when a compatible BMS is
detected. Setting 31 can be used to revert the charger to normal operation (i.e. without
BMS) by setting it manually to 'N'o. (for example if the charger is moved to another location
were a BMS is not needed).
Warning: do not set this parameter to 'Y'es when using a VE.Bus BMS connected to
the remote on-off port (see sect 3.5).
7) Load control mode (setting 35).
To use the relay (setting 11, value 10), or the VE.Direct port (setting 58, value 4) to control a
load according the options below:
Value
Description
0
Load output always off
1
Batterylife algorithm (default)
2
Conventional algorithm 1 (off<22.2V, on>26.2V)
3
Conventional algorithm 2 (off<23.6V, on>28.0V)
4
Load output always on
5
User defined algorithm 1 (off<20.0V, on>28.0V)
6
User defined algorithm 2 (off<20.0V<on<28.0V<off)
8) Backlight automatic turn-off has the following options: OFF=backlight remains lit all the
time, ON=the backlight will dim 60s after the last keypress, AUTO=when charging the
backlight is lit, otherwise it will dim.
