Safety Instructions:

Make sure your battery has enough voltage for the controller to recognize the battery type before the first installation.
The battery cable should be as short as possible to minimize loss.
The regulator is suitable only for lead acid batteries: OPEN, AGM, GEL
It is not suited for lithium, nickel metal hydride or other batteries.
The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.

System Connection:

Connect the battery to the solar charge regulator - plus and minus. It will show (1) if it detects a 12V battery or (2) if it detects a 24V battery.
Connect the photovoltaic module to the regulator - plus and minus.
Connect the load to the charge regulator - plus and minus.
