The solar charge controller optimizes the charging of the battery and its lifetime by means
of a three-stage charging algorithm and a configurable equalizing charge:
Charging stages
Description
Bulk charge stage
The battery is charged with the maximum power possible
depending on the input by the solar modules
Absorption stage
Battery charging at a constant voltage. The duration of the
absorption charge is configurable.
Float stage
Trickle charging at a constant voltage. If the battery voltage
drops below the threshold voltage for the float charge, a
switch to bulk charge is performed.
Equalize stage
The equalizing charge regenerates the battery to keep the
capacity loss over the lifetime as low as possible.
The equalizing charge function is controlled via the settings
in the programs 07, 08, 09, 10, 11, 12, and 13. To use the
function, it must have been activated in program 07.
Accessories (not included):
PA WiFi1: WiFi box to link the solar charge controller up with a web portal.

Installation
DANGER
Voltage
Under solar radiation, the solar modules and cables may be energised. There
is the risk of injuries and fire due electrocution and electric discharge.
►
Disconnect the connections from the power sources prior to any work on
the device.
►
Only have specialists carry out any installation work.
►
Only connect the cables to the solar charge controller when it is requested
by the instructions.
