Flashing sun: The controller limits the current, due to a full or almost full battery, to avoid battery overcharging. For
determination of the possible solar power, the battery must be discharged by a load (such as lighting) until the solar
controller supplies full power, and the sun symbol stops flashing.
Operating Mode
Mains Charger
The operating mode of the mains charger (AC Mode) is shown by the indicators “Off“, “AC“ and “Limit“" (at the displays
bottom) and can be switched by the button “AC Mode”.
There are three different states:
”AC“: Indicator points to ”AC“. Normal operation of the mains charger unit. In this case the solar charger unit is
inactive to the benefit of charging via AC.
“AC-Off“ (only VBCS Triple): Indicator points to ”AC-Off“. The mains charger unit is deactivated due to the benefit of
solar-charging despite being connected to a 230V supply. Under certain circumstances, for example low battery-
voltage, the Triple reactivates the mains charger unit automatically as long as it is required. The display continues to
show “AC-Off”.
“AC-Limit“: Indicator points to ”Limit – AC“. The mains charger unit is throttled to the point that the input current
consumption is limited and the internal fans are operated with constant, low speed.
This is useful at places with weak supply-infrastructure (weak fused e.g: only 4A). Moreover, in this operation the fans
generate a barely perceptible constant noise, which is especially beneficial at night. This is equivalent to the well-
known “Silent-Run“ mode of the VOTRONIC Chargers.
The AC modes are switched by the „AC-Mode“ button. The order is:
AC > AC-Off > AC-Limit and back to AC.
General Information
Cleaning:
We recommend to use a damp microfibre cloth with pure water or, if required, with water with a little soap.
Take care that no liquid flows along the display screen or the edges of the front panel!
Never use solvents, aggressive household cleaners, and scratching or abrasive agents or objects to clean the
front panel and particularly the display itself.
Trouble-Shooting
No display at all
Connection cable is intermitted, damaged, or it is not inserted
„Hieroglyphs“ on the display
Internal test programs have found (memory) error or communication has been disrupted by strong sources of interference
or poor cable connection. Remove the cable connector for 10 seconds. Clean the male contact with a fine brush.
