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 enables local adjustment of the voltage parameters for bcv, fcv, lvd and lvr. The charging power and charging current limiting function as well as the automatic reduction of the charging power ensure stability, even with oversized PV modules or high temperatures. In addition, it ensures stable performance within the operating temperature range at full load without loss of capacity. The IP33 protection standard and the isolated RS485 design improve the reliability and safety of the controller. The multi-load mode and extensive electronic and overheating protection functions provide protection against damage to the solar controller and connected devices.

High quality and advanced

The solar charge controller of the pro-x series is equipped with high-quality st and IR components from renowned brands, which guarantees a long service life and high reliability. The 3-stage charging mode based on a digital control circuit effectively extends battery life, significantly increases system performance and offers comprehensive protection against system or installation errors that could cause damage to components. This leads to increased operational safety and a longer service life for the entire solar power supply system. In addition, the intuitive control via PC software or mobile apps enables simple remote monitoring and control of the system.

Ultra-fast maximum power point tracking

Especially under changing light conditions, such as overcast skies, an extremely fast mppt controller significantly increases the 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 as well as the MPP loss time and precisely track the maximum power point (Multiple Peaks Maximum Power Point) of the PV system. This guarantees the optimal use of solar energy under all conditions and increases the energy utilization ratio by 10-30 % compared to the PWM charging method.
