Operating Instructions - Carbest 851005 User Instructions

UK
MPP:
If it is lighting: Proper functioning of the solar controller.
Short flashing: Display of readiness for service in case of missing solar power (at night).
No flashing: Installed fuse defective.
Battery Low (yellow):
If it is lighting: Low voltage at main battery I. Voltage <10.5 V
The battery should be recharged as soon as possible!
All pilot lamps (5) are flashing:
The positions of the selector switches »MAIN Battery« are incorrect.
For reasons of safety, the solar controller is switched off. Adjust the
desired battery type according to table 1.

OPERATING INSTRUCTIONS

1. Lifetime of the battery:
Recharge totally discharged batteries immediately!
Sulphation of the lead battery plates due to total discharge is to be prevented by soon charging,
particularly in case of high ambient temperatures. If the grade of sulphation is not too intensive,
the battery can recover part of the battery capacity after several charging/discharging cycles.
2. Partially Discharged Batteries: In contrast to other battery types, batteries on lead
basis do not have any harmful memory effect. Consequently: In case of doubt, partially
discharged batteries have to be charged fully as soon as possible. Always store only fully
charged lead batteries. Recharge them periodically, particularly in case of used (older)
batteries and higher temperatures.
3. Keep batteries cool and dry; choose an appropriate location for installation.
4. In case of insufficient solar power and/or high current consumption, the battery should
be subject to occasional full charging by means of a mains supply charger.
5. Overvoltage Protection: The 12 V solar controllers protect themselves against
connection of excessive battery voltage rates or will be switched off in case of
defective additional charging systems, switching threshold 15.0 – 16.0 V.
6. Overvoltage Limitation: Sensitive consumers are protected by means of a
limitation of the charging voltage to max. 15.0 V during all modes of charging.
7. Overload /Overheating Protection: The solar controller is equipped with a
double electronic protection against overload and with an automatic protection against
adverse installation conditions (e. g. insufficient ventilation, excessive ambient temperatures)
by gradual reduction of the charging capacity.
8. Voltage Measurement: Measurement of the voltage is to be effected at the
battery and never at the solar controller (loss at the charging cable).
