The Outback Power FM60-150VDC charge controller is engineered to optimize solar power systems efficiently. As a leader from the originators of MPPT technology, this controller offers robust performance and reliability. It's designed to maximize the energy harvest, increase photovoltaic array output by up to 30%, and operate effectively even under shading conditions. Ideal for diverse applications, it supports battery voltages from 12V to 60VDC, maintaining over 98% peak efficiency with minimal self-consumption.
This charge controller implements innovative MPPT software, actively adjusting to environmental conditions to enhance solar array output significantly. It stands as a de facto standard among system design professionals for multi-voltage systems.
Undergoing extensive reliability testing, including Highly Accelerated Life Testing, the FLEXmax 60/80 is built for mission-critical applications. It ensures dependable operation with a five-year standard warranty and an optional extension to ten years.
Featuring a smart programming wizard for quick configuration, the FLEXmax integrates seamlessly with any setup. External monitoring and control are possible via any internet-connected device using OPTICS RE, providing a powerful, user-friendly experience.
The unit comes with built-in data logging for up to 128 days, capturing critical metrics such as amp-hours, watt-hours, and peak performance values to fully assess the system's effectiveness and efficiency over time.
Fully network-compatible, the controller is equipped to integrate with an OutBack Power system, supporting customizable load controls to optimize energy distribution and management.
The FLEXmax charge controller manages solar power input by dynamically adjusting its operation to maximize energy capture from the panels. Its key components collaborate to ensure seamless voltage regulation and efficient charging of battery systems while also allowing extensive programmability.
The heart of the operation is the MPPT algorithm, continuously optimizing the relationship between solar array output and charge control for peak performance throughout varying light conditions.
The optional Remote Temperature Sensor (RTS) enables automatic temperature compensation, ensuring optimal battery maintenance and longevity by adjusting voltage settings according to ambient temperatures.
A 3.1" backlit LCD provides a comprehensive view of the system's status and simplifies both programming and real-time monitoring, enhancing user accessibility and control.
