1530W Flexpower Off-Grid Pre-Designed Solar System for 24v Battery Bank
This expandable 1,530 watt off-grid system has a pre-wired power center that makes it easy to install. The OutBack Flexpower is pre-wired with all of the essential protective devices in the smallest possible space at the lowest installed cost making it ideal for applications with modest power requirements such as cabins, weekend get-a-way homes, and remote communication sites as well as back-up power systems homes. Utilizing an extremely compact design and an easy-to-install mounting bracket, the fully pre-wired and tested Flexpower ONE System is engineered for a quick installation, saving both time and money. The pre-wired power center comes with an OutBack charge controller already mounted. OutBack charge controllers have maximum power point tracking with an efficient, safe, multi-stage recharging process that prolongs battery life and assures peak performance from the 1,530 Watt solar array. With a 24v battery bank the FM80 charge controller can take up to 2,400w of solar power, however because we need to keep the series strings of panels in sets of three panels ( due to the Max Voc input of 150V to the charge controller) a total of 9 x 255w solar panels can be used with the FM80 charge controller.
Flexpower by Outback includes a single AC inverter, AC and DC wiring boxes, a single Flexmax battery charge controller, MATE monitor, HUB, Flexnet DC and lighting surge protector. All this wrapped up in a 1,560w off-grid kit with a small power center footprint. The Flexpower System is also equipped with battery and breakers, a GFDI breaker, an input-output-bypass assembly, mounting locations for both AC GFCI Type B and EU Type F style outlets and additional AC breakers.
This expandable system has 25 year guaranteed UL listed solar panels, UL listed combiner box and we supply all the connectors from the panel to the box. You supply the conduit and wire from the box to the power center which is indoor rated. The 1,530 watt Off grid system is the only choice when you need a fully integrated off-grid system with pure sine wave inverter all pre-wired ready for you to add your own rack or select one of ours. With this pre-wired system you can save yourself thousands of dollars over the cost of hiring a contractor to install your system.

Lead Times for Shipping
Panels and balance of system ship in 3 – 5 business days after funds clear. OutBack FLEXpower™ ONE FP1-GVFX3524 power centers are usually in stock but are subject to inventory availability. Because of the popularity of the FLEXpower™ ONE; allow 10 business days to ship. (Subject to Seasonal Increases)
Off Grid or Grid Tied
FLEXpower™ 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 GVFX3524 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 VFX3524 inverters for your FLEXpower™ ONE system at no additional charge to you because the VFX3524 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.
Mounting and Battery Options
Roof 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. There are options below for racking (roof or ground), and batteries to accommodate nearly every application you might encounter.
Other Materials Needed
Some additional items sourced from your local hardware store that you may need to purchase are: Conduit, appropriately sized electrical wire from the combiner box to the location of the power panel, some fasteners, sealant, grounding rod and wire to complete the final connection to your main panel or sub panel.
Off-grid power systems are for those independent people who plan to live within their means and use only what they produce with solar panels, wind generators, hydro-power, or a combination of these.
OFF-GRID SYSTEM SIZING INFORMATION
Off-Grid System Sizing Information: Off-grid solar PV systems, like the one shown in the diagram above, are one of the most economical ways to provide electricity in the absence of an electrical power grid. Off-grid systems are useful for remote homes and cabins, RVs and boats, and even for industrial applications like remote telemetry, cathodic protection, and telecommunications.
The size of an off-grid solar electric system depends on the amount of power that is required (watts), the amount of time it is used (hours), and the amount of energy available from the sun in a particular area (sun-hours per day).
Off-grid power systems are designed differently than grid-tie systems. With a battery-less grid-tie system, calculations for system sizing are based on the yearly average peak sun-hours available at the site, and are used to offset the yearly power consumption drawn from the utiltiy grid.
With an off-grid system design, the calculations are usually based on the peak sun-hour figures for the darkest month of the year in order to provide sufficient on-site power year-round. In locations where it is not practical to install a renewable energy power system that will provide 100% autonomy during the darkest time of the year, a generator may be used to help run loads and charge the battery bank.
The first step in sizing an off grid system is to calculate the amount of power needed to run your appliances then you can use this information to calculate the size of the solar array required.
Off-grid power system design is complex, and these systems require specialized inverters, charge controllers, and battery banks.
