Charging Programs for LiFePO4-Batteries:
• The charging regulations of the battery manufacturer
are absolutely to be observed!
• An operation of the unit at a LiFePO4 battery without BMS Battery Management System and without
equalization charging of the cells (balancing) as well as safety circuit is not admissible!
• A battery temperature sensor must be installed at the battery (screw to the negative pole) and
connected at the unit. It serves as protection for the battery!
• If possible, the battery temperature must be kept above 0 °C.
Note: The possible parallel/floating operation with consumers being connected to the battery is also
automatically considered by all charging programs.

Holding voltage: 13.20 V Continuous
4. Slide Switches (CI-Bus adress switching):
The fourth slide switch is required for parallel operation of several CI-BUS solar controllers
on one CI-BUS line. The setting is made by the system integrator and has no significance
for operation without CI-BUS connection.
4. slide switch leave standard on "OFF" (bottom, see figure on the left)!
Further actions at the unit are not required during normal automatic mode.
