No More Dark-Out Grid-Tied Systems

No More Dark-Out Grid-Tied Systems

The grid-tied system your neighbor installed goes completely dark the moment the utility fails — that defeats the entire point of backup power. The Anker SOLIX F3800 Plus x2 with Double Voltage Hub delivers seamless instant backup transfer, keeping your home powered without interruption. Unlike piecing together random components from different vendors, this dual-unit system is pre-vetted by Off Grid Vault for full compatibility — the Double Voltage Hub, both F3800 Plus units, and your home panel all communicate as one architecture. At 12,000W max combined output across 120V/240V split-phase, you are running your well pump, refrigerator, and lights simultaneously through real outages, not simulated ones.

Charge Any Way the Conditions Demand

Charge Any Way the Conditions Demand

This off-grid proven system accepts up to 3,200W through dual 165V solar inputs — enough to connect eight 400W panels in any configuration that fits your site. When the sun disappears for days, the 240V 6,000W generator charging input keeps your batteries topped without switching systems. The 7,680Wh base capacity expands to 23.04kWh by adding up to six extra batteries, giving you real days of autonomy. With AC coupling technology, the F3800 Plus connects seamlessly to both your solar array and the grid, maximizing renewable energy use while maintaining full backup capability when the utility drops. Recharge time from AC input hits 100% in 2.67 hours at 1,800W.

Beat the Utility Rate Hikes Permanently

Beat the Utility Rate Hikes Permanently

The Anker app optimizes your energy strategy — charge during the day when solar production peaks and rates run low, then discharge at night when utility rates spike. The manufacturer projects up to $5,000 per year in savings, making the $4,385 system investment rational over a short payback period. Built for long-term dependability with 80% capacity retention after 3,000 charge cycles and an operational range from -4°F to 104°F, this system handles real weather extremes. The NEMA TT-30R and L14-30 outlets connect directly to your inlet box to power 10 essential loads — no extra accessories required. Your utility bill becomes optional.

System Compatibility Check

Confirm your setup meets these requirements before ordering.

  • Home panel supports 120V/240V split-phase at 50A or less
  • Solar array configured within 11-165V, 17A per MPPT input
  • Backup generator rated for 240V output at 6,000W or below

Built for Real-World Scenarios

From extended blackouts to daily energy management, this dual-unit system covers the situations that matter most.

“We had a four-day outage last January and this system ran our well pump, fridge, and heat without a hiccup. I was skeptical about portable power stations handling 240V split-phase, but the Double Voltage Hub made it seamless. No more gas generator noise, no more extension cord spaghetti. This is the real deal for anyone serious about backup power.”

Frequently Asked Questions

The manufacturer projects up to $5,000 per year in utility savings when using the Anker app to time-shift energy — charging during low-rate solar hours and discharging during peak pricing. At that rate, the system pays for itself in under a year. Beyond direct savings, you eliminate the cost of spoiled food, hotel stays, and generator fuel during outages. This is not an expense — it is a calculated investment that generates returns every month the utility company raises rates.
Off Grid Vault provides a free system design consultation before you purchase — our engineers verify that this dual-unit configuration matches your actual consumption, panel layout, and home panel setup. We are an authorized dealer, so warranty claims go through us, not a ticket queue. Every system package carries our compatibility guarantee: the Double Voltage Hub, both F3800 Plus units, and your connection points are pre-vetted to work together. You get human accountability from people who understand off-grid power, not a generic marketplace listing.
Yes. The dual-unit configuration delivers 12,000W max combined output across 120V/240V split-phase at 50A — enough headroom for heavy motor-start loads like well pumps alongside continuous loads like refrigerators. The NEMA L14-30 outlet provides direct 240V connection. If you want exact sizing for your specific appliances, our free system design consultation will calculate your real-world draw before you commit.
The F3800 Plus retains 80% capacity after 3,000 charge cycles. If you cycle the system once per day, that translates to over eight years before hitting 80% retention. The operational temperature range spans -4°F to 104°F, so it handles real climate extremes without degradation spikes. For context, a gas generator requires oil changes, filter replacements, and fuel stabilization — this system runs silently with no consumables. Warranty claims are handled directly through Off Grid Vault as an authorized dealer, so you have a clear support path if anything underperforms.
From a 1,800W AC input, the F3800 Plus recharges to 100% in 2.67 hours. With dual solar inputs supporting up to 3,200W total, you can recharge even faster during daylight hours using eight 400W panels. For extended cloud cover or winter conditions, the 240V 6,000W generator charging input lets you top off rapidly from a fuel generator without waiting. The auto-backup feature also pre-charges the system when severe weather is forecast, so you start the outage at full capacity rather than scrambling to recharge.
Yes. Each F3800 Plus supports up to six extra batteries at 3,840Wh each, bringing maximum capacity to 23.04kWh per unit. With two units in this package, your expansion ceiling is substantial. The system is designed to grow with your homestead — add panels to the 3,200W solar input, add batteries for longer autonomy, and scale as your cabin or home adds loads. Our free system design consultation can map your current usage and plan your expansion path so you buy the right capacity now without overpaying for power you will not use.
