Outback Flexmax 100 MPPT Solar Charge Controller - AFCI

Outback Power
FLEXmax 100-300VDC AFCI
MPPT Charge Controller

The FLEXmax 100 MPPT Charge Controller from Outback, is now updated to have integrated arc fault circuit detection and interruption for optimized systems. 

The advanced FM100 MPPT with AFCI eliminates the possibility of false arc-fault tripping, ensuring less downtime and loss of PV production.  The algorithm offers increased energy harvest from the PV array than other MPPT controllers. The FLEXmax 100 delivers both higher voltage and higher power, offering improved flexibility and performance.

OutBack network communications and OPTICS RE compatibility allows the FLEXmax 100 to be remotely programmed, monitored and controlled via any internet connected device providing unrivaled system integration.

The FM100-300VDC is a top-of-the-line high performance, efficient and versatile charge controller for your advanced power system.  Additionally, there will be huge labor and cost savings from not needing the external combiner box up on the roof.

Features:

• Improved: Integrated arc fault detection and interruption for optimized systems
• Improved: 100A output for up to 6kW of charging with up to 7kW on the PV array
• Improved: 300VDC open-circuit voltage limit enables up to 2-4 string configuration that minimizes BOS
• Improved: Programmable auxiliary control output for smart load controls
• Improved: Enhanced MPPT algorithm for increased energy harvest in harsh environments (ie. freezing temps, salty/dusty, or salty/marine areas)
• Compatible with 24, 36 and 48VDC battery banks
• Built-in and field replaceable arc fault circuit detection and interruption (AFCI), GFCI, and cooling fan
• Minimum battery bank size, 100Ah
• Field-upgradeable firmware (downloadable from Outback's website)
• System configures quickly with smart programming wizards (MATE3s required)
• Monitor, command, and control over the Internet with OPTICS RE
• Fully compliant with NEC 2017 RSD
• 5 Year Warranty (Upgraded to 7000W of nameplate solar power at 48V)
