Go Power AIC 3000W Inverter Charger 12V Single-Leg (83834)

The Go Power AIC 3000W Inverter Charger (model AIC-3000-12-SL, part 83834) packs three components into one unit so a 12-volt battery bank can run your rig like it's plugged into shore power. Inside the case you'll find a 3000-watt pure sine wave inverter, a 150-amp multi-stage battery charger, and a 30-amp single-leg automatic transfer switch. For a coach or trailer built around a standard 30-amp service, that's exactly the right combination, and it's the reason this single-leg model exists alongside the larger dual-leg version.

Start with the output quality, because it's what separates this from a bargain inverter. The AIC produces true pure sine wave AC at less than 3 percent total harmonic distortion. That's home-outlet quality power. Your residential fridge compressor runs quiet and cool, the microwave heats evenly, and anything with a motor or a variable-speed drive behaves the way it should. Sensitive electronics like laptops and CPAP machines don't like the choppy output of modified-wave units, and they'll run cleanly on this one. It's also rated at better than 85 percent peak efficiency, so more of your battery capacity actually reaches your loads instead of being lost as heat.

The single-leg 30-amp transfer switch is the key detail. Most travel trailers and mid-size motorhomes are wired for 30-amp shore service, and this model matches that setup directly. When you connect shore power or start the generator, the transfer switch passes that source straight through to your panel and the 150-amp charger kicks in to refill the batteries. Unplug, and the unit flips back to inverter mode fast enough that most loads never blink. There's no manual switch to throw and no breaker dance every time you move between hookups and boondocking.

That 150-amp charger is a genuine workhorse. Because it's multi-stage, it moves through bulk, absorption, and float on its own to bring a heavily discharged bank back up quickly and then hold it without overcharging. If you run a large lithium or AGM bank, that fast charge rate cuts your generator runtime and helps you recover in a hurry after a stretch of cloudy solar days. On the inverter side you get 3000 watts continuous with a 3300-watt surge for five minutes and a brief 6000-watt peak, so it has the muscle to start heavier motor loads and then settle into steady operation.

Monitoring is easy. The AIC connects over Bluetooth to the Go Power mobile app, so you can check inverter status, charge stage, and battery state from your phone rather than crawling into a storage bay to read a display. The unit is built to ABYC wiring guidance and carries UL 458 and CSA safety listings, which keeps professional installs clean and keeps your insurance happy.

Protection runs all the way through. The AIC watches for AC over and under voltage, DC over and under voltage, overcurrent, over and under frequency, short circuit, and over-temperature. If any of those step out of bounds, it shuts down to protect itself and the rest of your system instead of pushing through and risking damage.

This is the inverter charger for the boondocker or full-timer running a 30-amp rig who wants to leave the generator off for most of the day. Pair it with a battery bank sized for your real loads, wire it with correctly rated cable and fusing, and you've replaced three separate boxes with one clean power center. If your rig runs 50-amp split-phase service instead, look at the dual-leg version. But for the huge number of 30-amp coaches and trailers out there, the single-leg AIC 3000 is the right-sized, premium answer. It's quiet, it's efficient, and it just handles the handoff between shore, generator, and battery for you.
