Kontroler ładowania solarnego Offgridtec PWM Pro, 12 V/24 V, 20 A, USB

The Offgridtec 12/24-20 20A solar charge controller is a microprocessor-controlled controller with 3-stage PWM modulation for charging 12V, 24V AGM, GEL or lead-acid batteries.

• Max. 20A charging current
• For 260W / 520W PV power (12V/24V)
• Charges AGM, GEL and lead-acid batteries

The Offgridtec PWM 12/24-20 (MPN 010915) is a microprocessor-controlled solar charge controller with 20A max. charging power and can charge both 12V and 24V batteries. It works with 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 max. PV power of 260W at 12V and 520W at 24V battery voltage.

During charging, important environmental parameters such as battery temperature (only with optional sensor) are used to calculate the optimal 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 maximizes the service life of the batteries. It then continues to charge with reduced voltage until your batteries are actually "full". The result of this method is a better, faster charge without deteriorating the health of your battery.

Temperature-compensated battery charging (optional temperature sensor required, not included). Integrated device and battery protection

PV short-circuit protection - Automatic interruption of the connection in case of short circuit on the solar side.

PV reverse polarity protection - Automatically interrupts the connection if polarity is incorrectly connected on the solar side.

Overload protection - If the maximum permissible load current at the controller is exceeded by 5%, the controller automatically disconnects the existing load.

Overheating protection - If the heat sink temperature in the controller rises above 85°C, the device switches off automatically and switches on again as soon as the temperature drops below 70°C.

Short-circuit protection at the load output - Automatic interruption of the connection in case of short circuit at the load output.
