OutBack Power FLEXmax & SmartHarvest Charge Controllers

Outback Power MPPT Solar Charge Controllers

OutBack's real time active Maximum Power Point Tracking (MPPT) system ensures that your solar array is operating at its peak power point regardless of age, shading or environmental conditions,increasing the performance by 10-30%.

The FLEXmax series wide DC input range and 60-80 amp DC output current rating for 12, 24, 36, 48, or 60 VDC systems provides unmatched flexibility in the wiring as well as the sizing of your solar array.

The ability to efficiently step-down a high voltage solar array to a low voltage battery is one of the major advantages of these and other MPPT charge controllers. This feature can save you money by reducing the size of wire required and making the installation simpler and faster. Since you can often just wire up several solar panels in series without the need of a junction box or array combiner, wiring is usually very simple.

All Outback Power products must use the Outback "RTS" temperature sensor - if you are replacing or upgrading your controller from another manufacturer, you must replace the old battery temperature sensor.

Solar Controller EMI and RF Noise Note:

We have had some reports of high RF interference (EMI) noise being radiated by the Outback Flexmax controllers. If your solar system is being used for any type of communications system, such as cell phone relay, ham radio, or similar then we recommend that you use the Xantrex XW-SCC  or the Morningstar TS-MPPT charge controllers. Those are the currently the only solar charge controllers certified to FCC Class B, Part 15. This noise may also affect AM radio and TV reception.
