Offgridtec Per charge controller

The Offgridtec PWM 12/24-30 (MPN 1-01-010920) is a microprocessor-controlled solar charge controller with 30A max. charging power and can charge both 12V and 24V batteries. It employs modern, 3-stage PWM modulation to get the best out of your AGM, GEL or lead-acid batteries. It is suitable for solar systems with a maximum PV output of 390W at 12V and 780W at 24V battery voltage. During charging, important environmental parameters such as the battery temperature (only with optional sensor) are used to calculate the optimum charging current. As soon as the battery voltage is in the full charge range, the charging voltage is gradually reduced. This prevents both gassing and heating of the batteries and thus maximises the service life of the batteries. Charging then continues at a reduced voltage until your batteries are actually fully charged. The result of this method of operation is a better, faster charge without any deterioration in the health of your battery.
