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 voltage parameters for BCV, FCV, LVD and LVR. The limitation function of charging power and charging current as well as the automatic reduction of charging power ensure stability, even with oversized PV modules or high temperatures. The IP33 protection standard and the isolated RS485 design improve the reliability and safety of the controller. The multiple load mode as well as comprehensive electronic and overheating protection functions offer protection against damage to the solar controller and connected devices.

• High-quality and advanced

The 3-stage charging mode based on a digital control loop 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 of 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 cloudy 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 and MPP loss time and precisely track the maximum power point (multiple peaks maximum power point) of the PV system.
