Product Overview

This Sun Gold Power 4000W 12V split-phase pure sine wave inverter with charger is built for 12V battery systems that need both 120V and 240V AC power from one low-frequency unit. It combines an inverter, integrated battery charger, and AC auto-transfer switch in a single system for home, business, RV, trailer, boat, off-grid, and emergency backup setups. The goal is simple and practical: run a wide range of appliances on clean pure sine power, recharge the battery bank from AC input when available, and switch sources automatically when incoming power drops.

Split-phase output supports 120VAC and 240VAC, which helps keep mixed loads running without workarounds. The inverter output waveform is pure sine wave and includes bypass mode for stable AC delivery. Continuous output power is 4000W, with a surge rating of 12,000W for 20 seconds for short-duration start-ups and higher initial demand. Typical transfer time is 10ms, helping connected loads ride through quick source changes more smoothly.

This unit is designed around a 12V battery system with a nominal input voltage of 12V and a minimum start voltage of 10V. Battery voltage thresholds are clearly defined, including a low battery alarm range of 10.5V to 11.0V, a selectable low battery trip range of 10.0V to 10.5V, a high voltage alarm of 16V, and a low battery restart voltage of 13V. For systems that sit ready between events, idle consumption is 45W, with power saver mode idle consumption of 18W to help reduce standby draw.

Charging is handled by the integrated AC charger with a charger rate of 120A ±5A. The AC input range is selectable between 140–270VAC and 184–253VAC, with selectable charge settings based on battery type and adjustable charge current from 0% to 100%. Battery charging follows a 3-step intelligent battery charging process, and overcharge protection shutdown is specified at 15.7V. The unit also supports AC or battery priority selection, includes automatic generator start based on battery voltage, and provides an LCD display for system status monitoring. Remote control and a BTS cable are included for easier control and battery temperature sensing support.

What’s Included

  • 4000W 12V low-frequency pure sine inverter
  • User manual
  • Remote control
  • BTS cable

Best For

  • 12V battery-based backup power needing split-phase 120VAC and 240VAC output
  • RV, trailer, and marine systems that require pure sine wave power and integrated charging
  • Off-grid setups using AC input for battery charging and pass-through
  • Loads that benefit from 12,000W surge capability for short start-ups
  • Systems that want adjustable charging current from 0% to 100% with 3-step intelligent charging
  • Generator-supported setups using automatic transfer and automatic generator start based on battery voltage

Why This One Makes Sense

This unit is a practical way to run mixed 120V and 240V loads from a 12V battery system without stacking separate inverter, charger, and transfer components. You get 4000W continuous pure sine output with 12,000W surge for 20 seconds, plus bypass mode and a typical 10ms transfer time to support steadier source switching. The integrated 120A ±5A charger with selectable AC input range and 0% to 100% adjustable charging current supports tighter control over battery charging behavior, while power saver mode idle consumption of 18W helps reduce standby draw. With AC or battery priority selection, automatic generator start based on battery voltage, an LCD status display, and included remote control plus BTS cable, it fits systems that need dependable backup behavior and clear day-to-day control.

The durable resin strap and casing can withstand the wear and tear of an active lifestyle, ensuring longevity. The watch's functionality is where it truly shines. The digital display is easy to read, and the Indiglo backlight is a game-changer in low-light conditions. The 30-lap memory is a handy feature for tracking workouts or laps in the pool, while the countdown timer and alarm add practicality for daily use. Setting and adjusting the time and date are straightforward, thanks to the user-friendly interface. The watch also offers a dual time zone feature, making it a great companion for travelers. Battery life is impressive, providing long-lasting performance without the need for frequent replacements.

The Best for Athletics
Color: Black/Gray
This is a sleek, light wristwatch that will not weigh you down with its bulk. Forget the gigantic profile of a "survivalist" wristwatch. This unisex model is svelte and slim, not adding much to the wake you generate while swimming, or the swing of your arms while running, or the wind as it passes around your wrists and hands while you are speeding by on your racing bike. This is only 34mm across, by 35mm tall, by 11.5mm thick. The wristband is 13mm at its median working width. Timex styling cannot be beat, and neither is the resin-rubber-like material. I don't know about you, but the price is something I take a good look at. I want a watch that is reasonably priced and high-quality. I don't want to spend $200 to $1000 on a watch and worrying about being careful with it. If it gets smashed, it's only $30 to $50, not a big loss, and the quality is way better than what they were making in the 1980's. These watches are made for athletics and the real world.

Great watch, flimsy band
Color: Gray/Lilac
I bought this watch to replace a similar model because the band broke. I see this is a recurrent problem in many other reviews. However, I liked the watch enough to buy it again anyway. I found the new model easy to set, being fairly intuitive. So far it keeps perfect time. I use this watch mainly as a travel watch, and loved the dual time zone function. I am pleased that the newer model now has the ability to set 3 times zones instead of 2, which is an added bonus. The only con I see at this point is the flimsy strap. Unfortunately, the strap on this model is even thinner than on the previous one, and I wonder how long it will last. Also I wonder about the battery length. I think these watches may have been sitting around a long time. The setting showed 2012. I am afraid much of the battery life of the original battery may have already been used up and the battery may need replacing early. Only time will tell. The watch fits my small wrist fine and it is a little more attractive than the old model. I give it 4 stars instead of 5 only because of the band problem.

Fine for a man (with skinny wrists)
Color: Black/Gray, Color: Black/Gray
I have an older mens ironman which has gotten a little beat up and needs replacing. The band is much longer than I need. The metal clasp sits off-center on the underside of my wrist, closer to the part of my wrist which curves around to the front. The too-long strap sometimes flops around and catches on things. I couldn't find a smaller-band mens version, so I tried this "womens" watch (picking the most manly-looking one, of course). I like it better. The band fits my wrist much better, with the metal band in the middle and no flop. I also like that the watch is lighter and the face and band are smaller and less bulky, so it is less noticeable when I'm wearing it (cycling weight weenies will appreciate this). The face is still large enough to be easily legible and contains all of the same great features as my mens ironman watch, plus the newer versions now have an hourly chime, nice! Other info: my wrist is ~17.5cm or ~7.0" around. On this watch, I use the 6th out of 9 slots on the band. On my mens ironman, I use the 3rd out of 9 slots. Weight: this one = 28g, mens = 39g. Pics show comparison of my prior mens ironman with this new "womens" ironman. Photo order is confusing (couldn't figure out how to change that). They are: (1) side-by-side, mens on left, (2) mens band (wider and clasp is off-center on my wrist, end of band hangs over the edge of my wrist -- too long for me -- catches on things), (3) womens band (less wide, clasp is more centered on my wrist and end does hang over edge of my wrist), (3) womens watch (smaller, and looks new), and (5) mens watch, looking a little beat up.
