The new solar charge regulator PRS300 has been studied and manufactured in order to obtain the best possible performance of 12V photovoltaic modules up to 300W. It can be connected to the new test panel PT642 which is necessary in order to check the charging current of the photovoltaic modules and the battery’s voltage. PRS 300 works with lead-acid, lead-gel and AGM batteries and is able to maintain the ideal charging line (to be manually selected thanks to the commutator installed inside the solar charge regulator).

There is also a battery desulphatation function which is automatically enabled when the battery needs it. The four LEDs indicate:
 

• Battery charging with maximum current until the end-charge voltage is reached
• Charge maintenance at constant voltage
• Wrong connection alarm
• Solar charge regulator ON (in case of no solar light, the solar charge regulator turns automatically off)
