Regulation Voltages Board:
It has been checked that the regulation voltages programmed in factory, together
with the intelligent control of the regulator are the optimum for most of the
photovoltaic installations (housing, caravans, farms, etc.), for it WE ADVISE NOT
TO MODIFYTHESE PARAMETERS IF IT IS NOT STRICTLY NECESSARY.
An erroneous programming could damage the accumulators, electric or electronic
equipment connected in the installation, etc. Consequently, the modification of the
regulation voltages will be on the absolute responsibility of the installer.
If you want to modify the regulation voltages, you must take into account that:
1. This value will be for a C/50 at 25ºC, and that the internal algorithms of the programme
will be updated depending on the Cx and on the temperature.
2. For the 24 or 48 volts models, you must introduce the data divided into 2 or 4
respectively, as the voltage boards refer to 12 volts. Example: In 24 v. you want the
consumption restart voltage to be 25.4 v., then we must introduce 12.7, it is to say, 25.4/ 2.
You can directly modify 3 voltages values: Charge Final Voltage, Consumption Restart
Voltage, Consumption Unplugging Voltage.
Automatically, two more voltages are modified: High VoltageAlarm (it will be 0.03 volt./elem.
higher than Charge Final Voltage), Low Voltage Alarm (it will be 0.05 volt./elem. higher than
Consumption Unplugging Voltage).
Push simultaneously until 'ALL' appears on the display.
Push simultaneously until the first data appear on the display.
