OutBack Power Systems
Inverters and Charge Controllers

Outback Power Systems power inverters and combiner boxws

OutBack Power Systems has come up with a full line of charge controllers and sine wave inverters that make system design, installation, operation, and maintenance a breeze. All of these components can be easily tied together to form a safe and complete NEC-compliant system.  Note:  if you buy your power system from us, there will be system discounts over and above the prices listed here.


OutBack Power Systems FLEXmax MPPT Charge Controller

OutBack FLEXmax
charge controllers are the latest innovation in Maximum Power Point Tracking (MPPT) charge controllers. The innovative FLEXmax MPPT software algorithm is both continuous and active, increasing photovoltaic array power yield up to 30% compared to non-MPPT controllers. Providing active cooling and intelligent thermal management cooling, both FLEXmax charge controllers can operate at their full maximum current rating, 60 Amps or 80 Amps respectively, in ambient temperatures as high as 104F (40C).

FLEXmax charge controllers retain the revolutionary features first developed by OutBack Power, including support for a wide range of nominal battery voltages and the ability to step-down a higher voltage solar array to recharge a lower voltage battery bank. A built-in, backlit 80-character display shows the current status and logged system performance data for the last 128 days at the touch of a button. Integrated OutBack network communications allow remote programming and monitoring of FLEXmax series Charge Controllers via a MATE system display and provide unrivaled complete system integration.

Outback Power Systems FX Sine Wave Remote Power Inverters

OutBack Power's line-up of inverters has grown considerably over the past few years, now offering six different power levels at a variety of voltages ranging from 12 to 48 VDC. All FX inverters offer pure sinewave output, a high current battery charger, and AC transfer switch. Multiple pairs of FX inverters can be connected (using HUB) configured for 220/240 VAC split-phase output (using MATE) for a maximum of 10 inverters. Three FX inverters can be connected in parallel for 60 Amp AC input and transfer relay. The gasketed die-cast aluminum chassis protects and keeps the power conversion components cool. Sealed units are waterproof to IEC529 IP65 standards and have an operational temperature range of -40C to -60C. The vented version has stainless steel screens to protect the air intake and internal fan. The air inlet comes with a removable, washable foam filter insert. FX inverters are compatible with OutBack FLEXware enclosures and racks. All are 120VAC/60 Hz single phase. Available in 230 VAC/50 Hz versions and mobile versions with built-in AC-neutral/ground switching system. FX series can surge two times their power rating.
