The Sun-First Power Manager for Homes and Workshops

You have solar panels on the roof, a battery bank in the shed, maybe a backup generator, and the grid—when it feels like showing up. The question isn't whether you have enough power sources. It's how to make them work together without you standing there flipping switches all day. That's where the Winner So Series comes in. It's a hybrid inverter that thinks like a power manager, deciding in real time where your electricity comes from and where it goes. And it spans 1kW to 12kW, so whether you're running a small cabin or a fully equipped workshop, there's a size that fits.

Five Working Modes: You Call the Shots

Most inverters give you one way of doing things: grid first, battery backup. The Winner So gives you five, and you pick the one that matches your lifestyle—or your electricity bill.

`Mains priority is the classic: run off the grid most of the time, keep the battery topped up, and switch to inverter only when the grid fails. It's the mode for a home office in an area with occasional blackouts—you hardly notice the inverter is there until the lights go out.

`Battery priority flips that around. The inverter draws from your battery bank first, and only connects to the grid when the battery voltage drops below a threshold you set. This is the mode for time-of-use billing: charge your batteries cheaply at night, run off them during expensive daytime hours, and barely touch the grid when rates are high.

`Solar priority is where the "So" in the name earns its keep. The inverter pulls from your solar array first, supplements with battery when clouds roll in, and only reaches for the grid (or generator) when both are tapped out. On a sunny day, your house runs entirely on free power, and any surplus charges the battery for later. You're not exporting to the grid, you're not buying from the utility—you're just living off your own roof.

`Energy-saving mode idles the inverter down when there's no load connected. In an RV or a weekend cabin where the inverter might sit powered on but unused for hours, that cuts self-consumption and extends battery life.

`Unattended mode is for remote sites you can't visit every week—a telecom station, a water pump, a monitoring shed. The inverter manages everything on its own, restarting after faults, shedding loads if necessary, and keeping the batteries healthy without anyone touching a button.

You choose the mode from the LCD, and the unit remembers. It's not a marketing gimmick; it's real configurability that changes how your system behaves.

Solar-First, Without the Separate Charge Controller

The "So" variant is designed specifically for solar integration. It works with an external charge controller to turn your PV array into the primary power source. When the sun is up, the inverter prioritizes solar input for both running loads and charging batteries. If the grid is also available, you can configure how it blends: solar first, grid only when needed. For a household with a large array, that means months of near-zero utility consumption during summer. For a farm or workshop, it means daytime machinery runs on sunshine.

Configurable Charging: Fast Top-Up or Gentle Trickle

If you've got a generator, every minute it runs costs fuel. The Winner So offers AC charging current options that go from 5–35A all the way up to 5–70A, depending on the model. That's a genuinely fast charge rate. A 48V battery bank can go from 50% to full in a couple of hours of generator time rather than an entire day. And because the current is adjustable, you can dial it down for a small battery or crank it up when you're burning diesel and want the job done.

Battery Chemistry Is Your Choice

The Winner So ships with presets for flooded lead-acid, gel, and lithium (LiFePO4). Through the LCD, you can select the chemistry and adjust the charge voltage, float voltage, and low-voltage disconnect threshold to match your specific battery bank. If your lithium manufacturer recommends a particular absorption voltage, you set it. If you're nursing an older lead-acid bank that wants a slightly higher float, you tweak it. The inverter doesn't force a one-size-fits-all charge curve.

Pure Sine Wave and UPS Function

Output is pure sine wave—clean enough that sensitive electronics run cool, motors start smoothly, and you don't hear that annoying buzz from fans or LED drivers. The built-in UPS function means the transfer from grid to battery is fast enough that a computer doesn't reboot, a router doesn't drop, and a DVR doesn't miss a recording. It's not an afterthought; it's integrated into the DSP control, which constantly watches the grid and switches over before the waveform collapses.

Smart LCD That Actually Lets You Change Things

The front panel isn't just a display—it's a control centre. The smart LCD shows input voltage, output voltage, load percentage, battery status, and operating mode all at once. But more importantly, it lets you change settings without a laptop or a manual: working mode, charge current, charge voltage, input voltage range, battery low-voltage cutoff. If you want to adjust the system to match a new battery bank or a different usage pattern, you do it right there on the unit.

Protections That Don't Cry Wolf

High voltage, low voltage, overload, short circuit, over-temperature—all covered. There's also an optional battery reverse connection protection that saves you from an expensive wiring mistake. On startup, the unit runs an automatic self-diagnostic, checking internal components before it begins powering loads. And if a fault trips, the inverter attempts to clear and restart before it shuts down for good. That saves you a trip to the shed when the problem was just a fridge compressor kicking in at the same moment as a power tool.

DC Start and Monitoring

DC start means you can fire up the inverter directly from battery even with no grid, no solar, and no generator. In a blackout recovery scenario, that's essential. Standard communication ports include RS232 and RS485, with free PC software for local monitoring. If you want to check your system from the house—or from another city—optional WiFi is available for remote management via a mobile app.

Where the Winner So Fits

This is the inverter for anyone who has solar panels and wants them to be the primary power source:

`Homes with large rooftop arrays and time-of-use electricity pricing

`Off-grid cabins and farms that want to run primarily on solar during the day

`Workshops and small factories with daytime operations that can be offset by PV

`Rural clinics and schools where solar is the cheapest, most reliable energy source

`Anyone tired of paying for grid electricity when their roof is generating more than enough

The Winner So Series isn't a basic backup inverter with a solar input tacked on. It's a purpose-built hybrid that puts solar first, gives you real control over power priorities, and adapts to your battery chemistry and charging needs. If you've already invested in panels, this is the inverter that makes sure you're actually using the power they produce.
