Partially Discharged Batteries
(only for AGM and liquid electrolyte battery type)
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 must 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.
– Liquid electrolyte batteries can create explosive
gases, so ensure there is adequate ventilation.
Check the liquid level at regular intervals. Over-
charging can damage your battery; check the
technical data for your battery.
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.
Overvoltage Protection
The 12v 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 15.0-16.0v
Overvoltage Limit
Sensitive consumers are protected by means of a limitation of
the charging voltage to maximum 14.8v during all modes of
charging / battery type.
