MPPT-Laderegler Offgridtec Pro Duo, 30 A, 12 V/24 V, für zwei Batteriekreise

The Offgridtec MPPT Pro-Duo is an innovative high-end solar controller designed primarily for mobile applications.

• 30A max. charging power, for 12V and 24V systems
• Supports all common battery types, including modern lithium batteries
• Adaptive battery charging

The primary charging output (BATT-1) can charge a variety of on-board battery types, ranging from AGM, GEL, and flooded lead-acid to modern LiFePO4 and Li-NiCoMn battery systems.

The secondary battery charging output (BATT-2) is designed for a starter battery at the same voltage level as BATT-1.

The device automatically detects the system voltage of the starter battery (BATT-2), and charging of BATT-2 begins once the preset conditions are met.

The controller uses an advanced MPPT control algorithm that minimizes the maximum power point loss rate and loss time, quickly tracks the maximum power point (MPP) of the PV array, and extracts maximum energy from the PV array under all conditions.

Energy utilization in a PV system with an MPPT controller is increased by 20 to 30% compared to PWM charging.

• Features highlights of the MPPT Pro DUO 30 A

Max Power-Point Tracking technology with ultra-fast tracking speed and tracking efficiency of at least 99.5%.

Advanced MPPT control algorithm to minimize MPP loss rate and time loss.

• Wider MPP operating voltage range to improve PV module utilization.

Possibility to limit charging power by user or automatic charging current control (BATT-1).

Digital circuit control of adaptive three-stage charging mode to improve BATT-1 lifespan.

The product enters energy-saving mode when no manual input is made for a long time and charging conditions are not met (PV).

• 100% charging and discharging in operating temperature range.
• AES control signal for car refrigerator to avoid energy waste.
• Standard Modbus protocol and RS485 communication port (5V/200mA)
• Key technical features overview
• Optional remote display with mounting frame available.
• Support for all major battery types.

Max. solar power 390W at 12V system voltage and 780W at 24V system voltage

• 100V max. PV input voltage
• Intelligent energy saver

If no manual operation occurs for a long time and charging conditions are not met, the MPPT-Pro Duo switches to energy-saving mode, reducing the device's energy consumption to a minimum.

This behavior also reduces device wear, resulting in a significantly longer lifespan.

System parameters are displayed and set directly via the intuitive control panel on the controller or via the MT11 remote control (accessory).

• System communication and protection functions

The AES control signal for the refrigerator is built into the controller, which delivers excess solar power to the refrigerator to avoid energy waste.

The protection rating of the MPPT Duo is IP33. It withstands splashing water and is dustproof.
