OutBack Power RECOMMENDATION - Keep the number of parallel strings of batteries to three or fewer. More than three strings of batteries will shorten your battery life due to uneven charging. That means use higher AH 6VDC or 2VDC batteries for fewer strings. Batteries in Series = Voltage is Additive; Batteries in Parallel = Ah is Additive.

The Off-Grid or Grid-Interactive; Grid/Hybrid™ Solution w/ Mission US Mono Panels

OutBack Power Solar Production = 7,200 Watts Per Day ● Assumptions: STC 300 Watt Panel Rating [Factory Rating] @ 4.0 Sun Hours (Dec). Sun Hours should reflect the average value of total solar energy received in peak-sun-hours per day on an optimally-tilted surface during the month with the lowest solar radiation (not the yearly average). This is the best number to use in off-grid system design where the electrical demand is continuous or is not expected to vary seasonally and the system must be designed to operate year-round.


OutBack Power Technical Specifications: FP1 VFXR3648A-01 Power Center ● 48 VDC Battery Based Inverter. 120 VAC Output, Continuous Inverter AC Output Current 30 AAC ● Charge Controller FM80 Charge Controller FM80 Recommended Solar Maximum Array STC Nameplate 48VDC system = 5000W; ● 120 VAC Generator Compatible

IMPORTANT: Amps AC Output; Define Your Load Amp Requirements: OutBack Power 3.6kW FLEXpower One™ FP1 VFXR3648A-01 Pre-wired Power Center continuous AC output current is limited to 30 AAC. The concern here is that the combination of your normal loads (Not Surge Loads) might exceed the inverters output current rating (Amps Out). It is critical in the design selection that you make sure the continuous AC load combination of your power requirements at the site is at or below the 30 AAC output limit of a OutBack Power 3.6kW FLEXpower One™ power center.

The FLEXpower ONE is ideal for smaller residential applications including cabins, vacation homes, farm buildings, remote communications sites and back-up power systems, with all necessary components integrated into a compact hang-on-the-wall system with a minimal footprint.

● Factory tested, pre-wired and pre-configured systems

● Off-grid and grid-tied functionality in one flexible system

AC Input Connection

Programmable for seven different modes including GridZero, which blends utility power and stored renewable energy, minimizing grid dependence; also Support Mode for seamless generator integration.

Grid Tied

The Grid Tied mode allows the FP1 VFXR3648A-01 inverter to become grid-interactive. This means that in addition to using power from the utility grid for charging and loads, the inverter can also convert excess battery power and will export excess power to the utility grid. Excess battery power usually comes from renewable energy sources, such as solar arrays, hydroelectric turbines, and wind turbines.


Backup functionality requires a seperate critical load panel.

OutBack FP1 w/ Mate3s is Compliant with California Rule 21 and Hawaii 14H Grid Support Requirements. UL1741-SA (Rule-21)

CA Rule 21 currently governs CA & HI Rule 14H utility interconnection for all net energy metering for all projects permitted and approved for interconnection. The change was designed to create a standard for inverters more capable of dealing with a volatile utility grid. Why is this needed? Utility companies are facing higher penetration rates of solar and in some cases are saturated and needed an additional low/high frequency ride-through. By using so called smart inverters the functionality keeps grid voltage from oscillating or acts like a shock absorber intended result is automatic stabilization of utiltiy grid voltage.
