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