The Power Manager That Lets You Call the Shots

Most inverters are dumb. They sit between a battery and your appliances, convert DC to AC, and wait for the grid to fail. That's fine if your power situation is simple. But what if you've got solar panels on the roof, a generator in the shed, and utility power that charges a premium during peak hours? What if you want to run off battery all day, top up from the grid only when rates drop at night, and keep the whole system running unattended in a cabin you visit twice a year?

The Winner Series isn't a basic inverter. It's a configurable power management hub that lets you decide exactly where your electricity comes from, and when. It spans 1kW to 12kW, works with a wide range of battery voltages, and can be dialled in to match your lifestyle—not the other way around.

Five Working Modes, Because One Size Doesn't Fit All

The first thing you'll notice about the Winner is that it doesn't lock you into a single operating logic. You get five distinct working modes, selectable from the LCD panel:

`Mains Priority: The grid is your primary source. The inverter passes utility power through to your loads while keeping the battery charged. If the grid drops, it switches to inverter mode seamlessly. This is the mode for a typical home backup setup—you want the utility to do the heavy lifting, with battery as a safety net.

`Battery Priority: Flip the logic. The inverter draws from your battery bank first, and only switches to grid power when the battery voltage drops below a set threshold. This is the mode for solar setups where you want to use your stored energy before paying the utility. If you've got time-of-use billing and expensive daytime rates, battery priority mode saves real money.

`Solar Priority: If you have panels connected through a charge controller, this mode pulls from solar whenever there's enough sunlight, supplements with battery when there isn't, and falls back to grid only as a last resort. It maximizes self-consumption without you having to think about it.

`Unattended Mode: Designed for remote sites—think telecom towers, pumping stations, or that off-grid cabin you only visit in hunting season. The inverter makes all the decisions automatically, restarting after faults, managing battery charge, and staying online without anyone touching a button for months at a time.

`Energy-Saving Mode: When the connected load drops below a certain threshold, the inverter idles down to reduce its own power draw. When it senses a load again, it wakes up. Useful in RVs or tiny homes where every watt-hour counts.

You pick the mode that fits your usage pattern. It's not a compromise between features—you simply configure the Winner to behave the way you need it to.

Power Range and DC Flexibility

The Winner Series covers a broad spectrum: 1kW for a small office or cabin, up to 12kW for a full household or workshop. DC input voltages are available in 12V, 24V, 48V, and 96V configurations, depending on the power level. That means you can match the inverter to an existing battery bank without rewiring everything. If you've already got a 48V forklift battery or a 24V truck bank, there's a Winner that fits.

Serious Charging Current—Because Waiting Sucks

If you're charging a big battery bank from a generator, every minute of runtime costs fuel and noise. The Winner Series 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, 200Ah bank can go from flat to full in a few hours of generator time rather than an entire day. For off-grid homes where the generator is the backup to the backup, that charging speed turns a chore into a quick top-up. The charge current is adjustable from the LCD, so you can throttle it down for a smaller battery or crank it up when you're running the genset.

True UPS Function: Your Computer Won't Even Notice

The Winner includes an integrated UPS function. When the inverter is in mains priority or battery priority mode and the grid fails, the transfer to inverter power happens in milliseconds. A desktop computer keeps running. A router doesn't reboot. A security DVR doesn't miss a frame. It's not an external transfer switch bolted on—it's built into the inverter's DSP control, which monitors the grid constantly and switches over when the waveform goes out of spec.

Battery Compatibility That Adapts to You

The Winner Series doesn't care what chemistry your battery bank uses, as long as you tell it. The LCD menu lets you select lead-acid, gel, or lithium (LiFePO4) presets, each with appropriate charge voltage curves. And it goes further: you can manually adjust the charge voltage, float voltage, charge current, and low-voltage disconnect threshold. If your lithium battery manufacturer insists on a specific absorption voltage of 14.6V, you set it. If you're nursing an older lead-acid bank that wants a slightly higher float, you tweak it. The inverter adapts to the battery, not the other way around.

Protection That Tries to Recover Before It Quits

The Winner's protection suite covers the full checklist: high voltage, low voltage, overload, short circuit, over-temperature, and an optional battery reverse-connection protection. But the way it handles faults is worth noting. The unit includes automatic self-diagnostic routines and a DC start function—so you can fire it up directly from battery even with no grid present. If a fault triggers, the system attempts to restart and clear the issue before shutting down permanently. That saves you a site visit when the problem was just a momentary overload from a fridge compressor kicking in.

Monitoring That Doesn't Chain You to the Closet

Standard communication interfaces include RS232 and RS485, and the unit ships with free PC software for monitoring and configuration. If you want remote access—and for a 12kW system powering a whole house, you probably do—optional WiFi and remote monitoring modules are available. You can check load status, battery voltage, and mode settings from your phone without walking to the inverter room.

Generator-Friendly and Pure Sine Wave

The Winner's wide AC input voltage and frequency range makes it tolerant of generator output that would make a fussier inverter reject the source. Diesel and gasoline gensets with wandering governors or voltage sag under load won't cause the inverter to bounce between grid and battery modes. It syncs, accepts the power, and either passes it through to the load or uses it to charge the battery while keeping the output clean. And the output is always pure sine wave—no modified waveform that makes motors buzz and electronics run hot.

Where the Winner Earns Its Place

The Winner Series is for people who want control, not just backup. It fits a wide range of sites:

`Off-grid homes and cabins with solar and generator input

`Small businesses in areas with frequent outages and expensive daytime utility rates

`Farms and workshops running tools and pumps from a battery bank

`Remote telecom and monitoring stations that need unattended reliability

`Mobile applications like food trucks or RVs where power sources change frequently

If you've got a simple setup—one battery, one grid connection, no solar, no time-of-use pricing—a basic inverter will do. But if your power sources are multiple, your battery chemistry is specific, and you want to decide exactly when and how the system uses each energy source, the Winner Series is the configurable workhorse that puts you in charge.
