The OutBack FLEXpower™ ONE FP1-GVFX3648 is an advanced electronic device that takes DC (Direct Current) voltage from your batteries and turns it into 120V AC (Alternating Current) voltage, which is needed to power your household electrical appliances (i.e. AC loads). FLEXpower™ ONE includes a single inverter/charger, AC and DC wiring boxes, a single FLEXmax Charge Controller, MATE3, HUB, FLEXnet DC and Surge Protector. The FLEXpower™ ONE System is also equipped with battery and PV array breakers, PV GFDI, an Input-Output-Bypass Assembly, mounting locations for both AC GFCI Type B and EU Type F style outlets and additional AC breakers.

The FP1-GVFX3648 power center also includes a inverter battery charger circuit that takes AC power (When connected to your utility OR generator power) and transforms it into DC power to recharge your batteries from the inverter while the FLEXmax 80 is charging the batteries from the solar array. NOTE: Because few gas generators produce grid quality AC power, when using OutBack grid-interactive products in conjunction with a generator to recharge batteries, Outback only recommends using Honda EU generators. Flexware relay assembly may be necessary for auto start function of a two wire auto start generator.

The FLEXpower ONE system was designed with ease of installation in mind. The hanging bracket can be quickly installed allowing the entire system to be hung with minimal effort. OutBack FLEXpower™ ONE FP1-GVFX3648 power centers are a superior choice when you need a fully integrated, true sine wave, reliable 120V power system. FLEXpower™ ONE Warranty 5 Years, Solar Panel Warranty 25 Years.OutBack kits

flexpowerFLEXpower™ ONE FP1-GVFX3524 & FP1-GVFX3648 inverters are designed to work off-grid and also interact with the grid to back feed power. If you have a generator you should be aware that the GVFX3648 inverters will only sync with Honda EU generators because they produce pure sine wave power. If you intend to use your system completely off grid (No Grid Tie Ever), you may want to have us switch to the VFX3648 inverters for your FLEXpower™ ONE system at no additional charge to you because the VFX3648 will interface with a wider variety of generators. Should you choose to make that change, just notify us in the comment box at the time of checkout or when you are contacted by the technical consultant assigned to your purchase.

acRoof or ground racks and batteries are not included in the base price of the kit because they are site specific options. Mounting on the roof or ground, types of attachment are individual's specific property requirements.
