EcoFlow DELTA Pro Ultra X + 4 Renogy 400W Solar Suitcases + Free 50-Ft Cables

Free 50-Foot Solar Extension Cable Pair

AllProGenerators bundle bonus: This package includes one 50-foot red/black 10 AWG solar extension cable pair at no additional charge. Keep the DELTA Pro Ultra X protected while you position the solar array where the sunlight is better.

EcoFlow DELTA Pro Ultra X with Four Renogy 400W Solar Suitcases

This bundle is built for customers who want serious home backup power and a solar array they can put away when the storm season is over. It combines an EcoFlow DELTA Pro Ultra X inverter with two 6,144Wh batteries, four lightweight Renogy 400W solar suitcases, and the long extension cable pair needed to create more room between the batteries and the panels.

The result is 12.288kWh of LFP storage, 12kW of 120/240V AC output, and 1,600W of rated portable solar. Each panel folds down for storage, has its own kickstands, and weighs 30.2 pounds. You can deploy one panel for a small charging window or set up all four when you need the full array.

What Is Included

• 1 × EcoFlow DELTA Pro Ultra X inverter
• 2 × EcoFlow DELTA Pro Ultra X 6,144Wh LFP batteries
• 1 × EcoFlow trolley/base and standard system accessories
• 4 × Renogy 400W Lightweight Portable Solar Suitcases (SKU RSP400LSC-US)
• FREE 50-foot red/black 10 AWG solar extension cable pair
• USA-based support from AllProGenerators

Why This Bundle Is Different

Our other Ultra X solar packages use EcoFlow panels. This version is for the customer who wants the Renogy suitcase format: lighter 30.2-pound panels, compact folded storage, built-in aluminum kickstands, and MC4-compatible leads. Four separate suitcases also make the array easier to move in stages instead of wrestling with one permanently mounted rack.

• Portable 1,600W array: Four independent 400W panels can be positioned around shade and uneven ground.
• Whole-home-class output: 12kW split-phase 120/240V power for compatible household loads.
• Useful starting capacity: Two batteries provide 12.288kWh before any expansion.
• Expandable platform: One Ultra X inverter supports up to ten 6,144Wh batteries.
• Long cable reach: The included 50-foot pair lets the power station stay farther from heat, rain, and direct sun.
• Fast setup and storage: No permanent roof rack is required for the four portable panels.

Solar Compatibility and Array Planning

Each Renogy suitcase is rated at 47.2V open circuit, 40V at maximum power, and 10A operating current. Using the four panels as a properly configured series string gives published STC values of approximately 188.8V open circuit, 160V operating voltage, 10A, and 1,600W. Those values fall inside one DELTA Pro Ultra X high-voltage PV input's published 80–500V, 15A, 5,000W limits.

The Ultra X provides two high-voltage PV inputs with up to 10kW combined input. EcoFlow specifies use of its PV Switch Box for the standard solar connection. Final wiring must follow the current EcoFlow and Renogy manuals, account for cold-weather voltage correction, and remain within every per-input voltage, current, and wattage limit. Solar production varies with sun angle, temperature, cloud cover, shading, cable length, and site conditions.

Best Uses

• Whole-home or selected-load backup with compatible transfer equipment
• Running compatible 120V and 240V appliances
• Remote property, cabin, farm, and workshop backup
• RV and mobile applications that need substantial stored energy
• Customers who cannot install permanent rooftop solar
• Temporary solar charging that can be packed away between uses

Frequently Asked Questions

Does this package include two Ultra X batteries?

Yes. The system includes two 6,144Wh LFP batteries for 12.288kWh of starting storage.

Are there really four 400W Renogy panels?

Yes. You receive four individual Renogy 400W Lightweight Portable Solar Suitcases, for 1,600W of combined nameplate power under standard test conditions.

Are the solar extension cables free?

Yes. One 50-foot red/black 10 AWG solar extension cable pair is included as an AllProGenerators bundle bonus.

Can all four panels connect to one Ultra X PV input?

The published STC electrical values of a four-panel series string fall within one Ultra X high-voltage PV input's published range. Follow the current manuals and EcoFlow PV Switch Box connection requirements, and verify the finished string's cold-weather voltage before installation.

Can I connect the panels in parallel instead?

Do not choose a series or parallel layout by wattage alone. Four panels in parallel would exceed a 15A input limit. Use the configuration specified by the current equipment manuals or a qualified solar installer.

Will the panels make 1,600W all day?

No portable array produces its nameplate rating continuously. Actual output changes with sunlight, season, shade, panel angle, temperature, cleanliness, and conversion losses.

Can the Ultra X run 240V equipment?

Yes, the Ultra X supplies 120/240V split-phase power and includes NEMA L14-30 and NEMA 14-50 outlets. Confirm the running and starting requirements of every connected load.

Can I add more batteries later?

Yes. One inverter supports up to ten compatible 6,144Wh batteries, for as much as 61.44kWh of storage.

Is this a permanently installed solar system?

No. The Renogy suitcases are portable panels with built-in kickstands. They are intended for temporary deployment and storage, which is useful for customers who do not want fixed roof panels.

Do I need an electrician?

The portable power station can be used on its own, but any connection to a home electrical system, transfer equipment, or permanent wiring should be completed in accordance with local code by a qualified professional.

Built for Real Backup Power

If you want a battery system that can handle demanding household loads and a solar array you can still move without a crew, this package is a strong middle ground. You get the Ultra X platform, two batteries, four lighter Renogy suitcases, and the extra cable reach in one order—without locking the panels onto a roof.
