1.2.3 Charge current adjust
The charge current can be adjusted by the potentiometer on the front panel top from 0A up to
maximum rated charge current (see recommended charge current table beside).
Recommended battery capacity versus charging currents (at 20°C battery temperature)
ATTENTION
If sealed lead acid batteries are overcharged it
will result in gassing and dry-out and the
battery will be destroyed.
Wet batteries (open type) will loose water and
need to be topping up.
If you are in doubt how your batteries shall be
charged, please consult your Battery
Technical Manual (data sheet), or your local
battery distributor.
Temperatur-compensation (NTC-Sensor)
When using the external temperature sensor (NTC) the charger will reduce the charge current
in respect to the max allowed battery voltage at the actual temperature!
Use the NTC temperature sensor for optimal battery performance.
Graphic shows the
automatic adaptation of
charging voltage in
respect to the actual
measured temperature.
At 20°C the boost charge
max voltage is 14,4V and
float charge voltage
13,5V.
1.3 Backup-Mode
In case of black out of AC public grid, the device will switch over automatically to inverter
function and the connected AC-equipment will still run powered by the battery. This happens
without interruption of AC-supply.
Important: for backup-mode, the inverter section always must be switched on!
Note: If inverter is switched to OFF, there only will be AC-voltage on AC-Output, when AC-
voltage exists at AC-Input of inverter.
