4 Proper usage
The solar charge controller, hereinafter named as the controller or device, may only be used in stand-
alone photovoltaic systems for charging and controlling a lead-acid battery containing liquid or gel
electrolyte. The following applies in addition:
QThe controller must not be connected to the public power grid.
QOnly solar modules may be connected to the solar module connection.
QDepending on the battery used, the connected loads must be suitable for use with one of the
following voltages:
Tarom 4545: 12 VDC, 24 VDC
Tarom 4545–48: 12 VDC, 24 VDC, 48 VDC
QThe controller performs the following tasks:
– Monitoring of the battery charging process
– Controlling of the charging process, protection of the battery from overcharging
– Switching loads on and off, protection of the battery from deep discharge
