Description
OutBack Power FLEXmax 60 Amp 150 V MPPT Charge Controller (FM60-150)
Overview
The OutBack Power FLEXmax 60 (FM60-150) is a professional-grade MPPT (Maximum Power Point Tracking) solar charge controller designed for demanding battery-based systems in off-grid, grid-hybrid, or remote-site applications. With up to 60 amps of charging current and a high PV input capability of up to 150 VDC, this single controller supports battery banks of 12 V, 24 V, 36 V, 48 V or 60 VDC (field-selectable) in one unit. :contentReference[oaicite:1]{index=1}
The advanced continuous MPPT algorithm from OutBack optimizes solar harvest: you can see array output gains of up to 30% when compared to traditional PWM controllers. :contentReference[oaicite:2]{index=2} Built-in data logging of the last 128 days, an 80‐character backlit display, and remote network integration make the FLEXmax 60 ideal for systems where performance visibility and system control matter.
Domestic sourcing matters—here’s how this product qualifies:

Design & Performance
The FLEXmax 60 is built for the kind of sustained performance you expect in remote or harsh environments. The active cooling and intelligent thermal design allow the controller to deliver rated output even at high ambient temperatures, reducing system derate risk. Because it supports high PV input voltages and delivers adaptive MPPT to a wide range of nominal battery voltages, it offers installers design flexibility and efficient wiring strategies.
Whether you’re charging a 12 V bank in a remote cabin or a 60 V battery stack in a commercial hybrid system, the FLEXmax 60 adjusts to your architecture. Its network integration and logging features give system owners clear insight into performance and help streamline operations and maintenance.
Integration & Expandability
- Seamlessly interfaces with OutBack inverters and system monitoring platforms (MATE/OPTICS RE). :contentReference[oaicite:13]{index=13}
- The programmable auxiliary output can be configured to initiate fan cooling, gen‐start relays, alarms or remote shut-off based on battery state or system temperature.
- Ideal for professional off-grid solar, telecom shelters, backup power, micro-grid nodes, and system integrators who demand reliable, flexible charge control.
