PROTECTIVE FEATURES
Battery overvoltage, disconnection
When the battery voltage reaches the overvoltage limit the charge controller stops the charging to
protect the battery from damage.
Battery undervoltage, over-discharge protection
When the battery voltage reaches the undervoltage limit for over-discharging the charge controller
stops the discharging of the battery to protect the battery from over-discharge damage.
Overcurrent protection
The power supply to the connected load is switched off when the current exceeds the rated current
1.25 times. The user must then reduce the connected total load and press the load switch button to
reconnect the load.
Short-circuit protection
The power supply to the connected load is switched off if there is a short circuit in the connected load
(a short circuit is considered to have occurred if the current is 3 times more than the rated current).
The user must then rectify the short circuit and press the load switch button to reconnect the load.
Transient voltage suppression
The charge controller is protected from moderate transient overvoltages. This is only a basic
protection – if powerful transient overvoltages are expected, for example in areas subject to frequent
thunder storms, the protector should be supplemented with an external transient voltage protector.
