3Installation:

Connect the individual components to the symbols provided, they are solar panel,

battery and loads in order. Only install the regulator near the battery on a suitable

surface. This surface should be solid, stabile, even, dry and nonflammable. The battery

cable should be as short as possible (1-2 m) and have a suitable cable diameter

size to minimize loss, e.g. use 2.5 mm² at 10 A and 2 m length; 4 mm² at

20 A and 2m length; 6 mm² at 30 A and 2 m length.

Observe the following connection sequence during commissioning:

1. Connect the battery to the charge regulator - plus and minus, note the fuse current

should be 2 or 2.5 times of the rated current.

2. Connect the photovoltaic module to the charge regulator

- plus and minus

3. Connect the consumer to the charge regulator - plus and minus

Please observe that the automatic adjustment to 12V / 24V systems

does not function properly, if this sequence order is not followed. An

improper sequence order can damage the battery!

4 Operation & instructions:
