Outback Power FLEXmax FM60 & FM80 – The Gold Standard in MPPT Charge Controllers
Your solar panels are only as good as the charge controller managing them. Without a high-quality controller, you're leaving energy on the table – and potentially damaging your battery bank.
That's where Outback Power's FLEXmax series comes in. The FM60 and FM80 are widely regarded as the most advanced MPPT charge controllers on the market, built for off-grid homeowners, remote industrial sites, and anyone who demands maximum performance from their solar array.
Why Choose MPPT? Up to 30% More Power
Traditional PWM controllers waste potential power. The FLEXmax series uses continuous, active Maximum Power Point Tracking (MPPT) that constantly adjusts to find the perfect voltage-current sweet spot from your panels. The result? Up to 30% more power yield compared to non-MPPT controllers.
FM60 vs. FM80 – Which One Is Right for You?
Both controllers share the same core technology and features. The only difference is output current:
| Feature | FLEXmax FM60 | FLEXmax FM80 |
|---|---|---|
| Maximum Output Current | 60 Amps | 80 Amps |
| Best For | Smaller to mid-sized arrays | Larger arrays |
| NEC Recommended Solar Array (STC) – 12V | 750W | 1000W |
| NEC Recommended Solar Array (STC) – 24V | 1,500W | 2,000W |
| NEC Recommended Solar Array (STC) – 48V | 3,000W | 4,000W |
