One Box, Both Voltages, No Workarounds

If you're setting up off-grid power anywhere that runs on the North American split-phase standard—120V for your lights and outlets, 240V for your well pump, water heater, or air compressor—you've probably bumped into a frustrating reality. Most inverters give you one voltage, not both. The "solution" usually involves buying two inverters, wiring them in a stacked configuration, adding an autotransformer, or just living without one of the voltages and running a generator every time you need to pump water. The Winner Sp Series simply does away with that mess. It's a single inverter that outputs true split-phase power, so you get both 120V and 240V from one unit, right out of the box.

One Inverter, Three Outputs, No Transformer

The Winner Sp's output block is straightforward. You've got a HOT1, a HOT2, and a Neutral. Measure between HOT1 and Neutral, you get your choice of 100/110/115/120V. Measure between HOT2 and Neutral, same. Measure across HOT1 and HOT2, you get 200/220/230/240V. That's it. You wire your standard household receptacles to one of the 120V circuits, and your heavy 240V appliances across the two hot legs. No external transformer humming in the corner, no second inverter to sync, and no complicated load-balancing spreadsheet. If your cabin has a 120V fridge, a few LED lights, and a 240V deep‑well pump, the Winner Sp powers all of them simultaneously.

Pure Sine Wave That Won't Punish Your Electronics

The AC waveform is a clean, utility-grade sine wave. Not a stepped approximation that makes motors buzz and electronics run hot. Your variable-speed drill, your microwave, your laptop charger—they all get the kind of power they were designed to run on. In an off-grid home or a full‑time RV, that output quality is non-negotiable. A modified sine wave might save you a few dollars upfront, but it'll cost you in the long run with motors that wear out faster and electronics that behave strangely. The Winner Sp doesn't cut that corner.

DC Voltage Options That Match Your Battery Bank

The Winner Sp covers 1kW to 12kW, and the DC input voltage is available in 12V, 24V, 48V, or 96V—so you can pair it with whatever battery bank you already have or are planning to build. If you've got a small cabin with a 24V forklift battery, there's a model that matches. If you're building a larger system with a 48V lithium stack, same. You're not forced into a voltage that doesn't fit your existing infrastructure.

Five Working Modes: You Decide the Power Strategy

Like the rest of the Winner family, the Sp Series gives you five selectable working modes, so the inverter behaves the way you need it to, not the way the factory assumed.

`Mains priority is the simple backup mode: run off the grid when it's there, keep the battery charged, and switch to inverter only when the grid fails. Perfect for a rural property with frequent but short outages.

`Battery priority flips that: draw from your battery bank first, and only connect to the grid when the battery voltage drops to a set threshold. This is the mode for time-of-use billing—charge your batteries when electricity is cheap, run off them when it's expensive.

`Solar priority puts your PV array in charge. The inverter pulls from solar first, supplements with battery, and only reaches for grid or generator as a last resort. On a sunny day, your house runs entirely on free power. Surplus charges the battery. If you've invested in panels, this is the mode that maximizes their payback.

`Energy-saving mode idles the inverter down when there's no load connected. In a weekend cabin that sits empty for five days at a time, that cuts the inverter's own power draw and stretches the battery bank.

`Unattended mode is built for remote sites—a telecom hut, a monitoring station, a water pumping shed. The inverter makes its own decisions, restarts after faults, and keeps the batteries healthy without anyone pressing a button for months at a time.

You select the mode from the front-panel LCD, and the Winner Sp remembers it. It's not a locked-down box. You actually configure how it behaves.

Charging That Adapts to Your Generator and Your Batteries

If you're using a generator to top up the battery bank, every minute of run time costs fuel. The Winner Sp's AC charger is adjustable from 5–35A standard, with an optional upgrade to 5–70A. A 48V, 200Ah bank can go from empty to full in a few hours of generator time instead of an entire day. And because the charge current is adjustable, you can throttle it down for a smaller battery or crank it up when you're running the genset.

The charger works with lead-acid, gel, and lithium (LiFePO4) batteries. Through the LCD, you set the battery type and, if needed, fine-tune the absorption voltage, float voltage, and low-voltage disconnect threshold. If your lithium BMS calls for a specific charge profile, you can dial it in. The inverter adapts to your battery, not the other way around.

UPS Function, Generator Compatibility, and DC Start

The built-in UPS function means the transfer from grid to battery is fast enough that a computer doesn't reboot. The DSP controller constantly watches the grid voltage and frequency, and the moment they go out of spec, it switches to inverter power seamlessly. When the grid returns, it re-synchronises and transfers back just as cleanly.

The AC input window is deliberately wide—both voltage and frequency—so a portable generator with a wandering governor won't cause the inverter to reject the source and cycle between grid and battery modes. The Winner Sp accepts rough generator power, cleans it up, and either passes it through or uses it to charge the battery while keeping the output clean.

DC start capability means you can power up the inverter from battery alone even with no grid, no solar, and no generator present. In a blackout recovery scenario, that's essential.

Smart LCD That Actually Lets You Change Things

The front-panel LCD isn't just a passive display. It shows you input and output voltage, load percentage, battery status, and operating mode all at once. But more importantly, it lets you change settings right from the panel: working mode, charge current, charge voltage, input voltage range, battery low-voltage cutoff. You're not digging for a manual or plugging in a laptop. The inverter is fully configurable from the front.

Protections That Don't Shout Wolf

High voltage, low voltage, overload, short circuit, over-temperature—all present. There's also an optional battery reverse-connection protection that saves you from a very expensive wiring mistake. On startup, the unit runs an automatic self-diagnostic, checking internal components before it begins powering loads. And if a fault does trip, the inverter attempts to clear and restart before it shuts down for good. Often, a temporary surge from a motor starting clears on its own—the Winner Sp gives it the chance to recover.

Monitoring: Local or Remote

Standard communication ports include RS232 and RS485, with free PC software for local monitoring and setup. If you want to check the system from your phone—production, consumption, battery state—the optional WiFi module gives you remote access via a mobile app. For a seasonal cabin or a remote site, that visibility is invaluable. You know the system status before you drive three hours up a dirt road.

Where the Winner Sp Fits

This is the inverter for anyone in split-phase territory who wants a single-box solution that powers both voltages without workarounds:

`Off-grid homes and cabins in the US, Canada, Mexico, and parts of Latin America

`Full-time RV setups that need 120V for outlets and 240V for a high-power air conditioner or dryer

`Remote workshops running a mix of 120V hand tools and 240V compressors or welders

`Farms with irrigation pumps (240V) and household loads (120V) in the same building

`Small commercial sites in rural areas where the grid is unreliable and a generator is the backup

If you've been looking at two inverters and a transformer just to get split-phase power, the Winner Sp Series simplifies the parts list. It's one box that delivers clean, configurable, true split-phase output from 1kW to 12kW, with all the modes, protections, and monitoring you'd expect from the Winner family. No compromises, no workarounds—just the power your site actually needs, wired the way it's meant to be.
