CONNECTION

- The polarities ( + and – ) of solar panel and batteries are absolutely to be
observed! Observe the cross-sections and length measures of the cables!
- Connection of the solar controller to the battery »Board I« should be effected first.
Cable Protection: the fuses near the batteries into the + cables
(protection against cable fire)!
- The solar panels should be protected from direct sunlight (by covering or shading)
prior to connection.
1. Main Battery »MAIN I« –– > must be connected:
Connect the battery connections of the controller – (Minus) and + (Plus) to the 12 V main batte-
ry, observing the correct polarity and the cross section of the cables (refer to connection plan).
Never operate the controller without the battery »Main I«. If the battery is not
connected, the unit will not deliver a defined output voltage.
In case of wrong polarity of battery I, the internal safety fuse will be released. The replacement
fuse should have the same capacity, and it should be of the same type (car fuse)!
Parallel charging of two or several batteries of the same voltage (12 V)
is admissible. The batteries are to be »paralleled«.
2. Solar Panel –– > must be connected:
Shade the panels to minimize sparking during connection and to avoid damages due to eventual
wrong polarity. Observe the cable cross-sections (refer to connection plan)! If several small solar
panels are used, they are connected in parallel (refer to connection plan). Partial shading of the
panels results in average higher capacity (see connection plan).
3. Starter Battery »START II« –– > can be connected:
Connect the second charging port to the second battery using the red connection cable. This
cable may be longer. In case of non-utilization, this terminal is left free. If used, the output for
starter battery II will be working with reduced voltage and charging current rates. Thus, the valu-
able solar power will be supplied to board/solar battery I being more suitable. However, the vehi-
cles starter battery II will be kept in a condition, that starting will always be possible, even in
case of longer downtimes and during winter operation.
Connection of the negative pole »START II« is not required, if the negative pole »BOARD I« is con-
nected to the vehicle body. Depending on the length of the cable, it may also be connected to the
common negative connection of the solar controller or to the negative pole of »BOARD I«.
