Reliable, flexible, and safe

The Offgridtec MPPT PRO-X solar charge controller is a versatile powerhouse. It is compatible with lead-acid and lithium-ion batteries and allows local adjustment of voltage parameters for BCV, FCV, LVD, and LVR. The charging power and charging current limitation function and the automatic reduction of the charging power ensure stability, even with oversized PV modules or high temperatures. In addition, it ensures stable performance without capacity loss during full-load operation within the operating temperature range. The IP33 protection standard and the isolated RS485 design improve the reliability and safety of the controller. The multiple load mode and extensive electronic and overheating protection functions offer protection against damage to the solar controller and connected devices.

High quality and advanced

The PRO-X series solar charge controller is equipped with high-quality ST and IR components from renowned brands, guaranteeing a long service life and high reliability. The 3-stage charging mode, based on a digital control loop, effectively extends battery life, significantly increases system performance, and provides comprehensive protection against system or installation errors that could cause damage to components. This results in increased operational reliability and a longer service life for the entire solar power supply system. In addition, intuitive control via PC software or mobile apps enables easy remote monitoring and control of the system.

Ultra-fast maximum power point tracking

Especially under changing light conditions, such as when the sky is overcast, an extremely fast MPPT controller significantly increases energy yield and ensures a minimum efficiency of 99.5%. With the optimized MPPT control algorithm, the Offgridtec controllers from the PRO-X series minimize the MPP loss rate and MPP loss time and precisely track the maximum power point (Multiple Peaks Maximum Power Point) of the PV system. This guarantees optimal use of solar energy under all conditions and increases the energy utilization ratio by 10-30% compared to the PWM charging method.
