Product Description

Our product has a number of safety and display functions.
Clear readable LED display of the state of charge.
Acoustic signal when the state of charge changes.
Low voltage disconnect regulated by state of charge or voltage.
The controller adjusts itself automatically to *2V or *4V system voltage.
Max.*6 mm² connector binding posts. Max safety current can reach *1A.
The charging characteristics include automatic adoption to the ambient temperature.
Complete electronic protection.
Wiring and grounding:
The controller is intended for indoor use only or installed in distribution box. Protect it from direct sunlight and rain. If installed in distribution box, should avoid the position of condensed water drip. The controller measures the ambient temperature to adapt the charging voltage. To ensure the start-up of controller, battery voltage should exceed *0V if the system voltage is *2V, and battery voltage should exceed *0V if the system voltage is *4V.
If the battery voltage is not within the normal operation range at start-up, a status display according to the section ERROR DESCRIPTION occurs.
Connect the controller by following steps to avoid installation faults.
1. Connect the wire to the controller, then to the battery.
2. Connect the wire to the controller, then to the photovoltaic modules.
3. Connect the wire to the load, then to the controller.
                                    
 All positive connections of SLAC-H controller are common and therefore have the same electrical potential. If any grounding is required, always do this on the positive wire. Special grounding terminal can be used for controller shell grounding.
If the controller is used in a vehicle which has the battery negative on the chassis, loads connected to the controller must not have an electric connection to the car body. Otherwise the Low Voltage Disconnect function and the electronic fuse function of the controller are short circuited.
REMARK:Mind the recommendations of your battery manufacturer. We strongly recommend connect a fuse directly to the battery to protect any short circuit at the battery wiring. The fuse must correspond to 1.5 times the nominal current of the controller.
Starting up the controller:
Self Test
As soon as the controller is supplied with power from the battery, it starts a self test routine. Then the display changes to normal operation.
The controller adjusts itself automatically to *2V or *4V system. As soon as the voltage at the time of start-up exceeds *0V, the controller assumes a *4V system.
If the battery voltage is not within the normal operation range at start-up, a
status display according to the section ERROR DESCRIPTION occurs.

Safety features:
SLACH safety features can protect the controller to avoid damage to products due to incorrect installation or use.
