The Go Power! ASW-1800-12-TS combines a 12 volt, 1800 watt pure sine wave inverter with a 30 amp automatic transfer switch in one hardwired unit. Wire it between the shore inlet and your AC panel once. Shore or generator power passes straight through when it is available, and the inverter takes over from the battery within 20 milliseconds when it drops.
Go Power sizes the 1800 W model for single 30 A coaches that run a 1000 W microwave, a coffee maker or a residential fridge, one high-draw item at a time. It is UL Listed to UL 458, works with the PowerTrak RV-C system and carries a 2-year warranty from Go Power.
The internal transfer relay is rated 30 A continuous with a transfer time of 20 ms or less. It accepts 120 VAC nominal input across a 70 to 150 VAC range and 57 to 63 Hz, and the AC input is protected by a 30 A breaker that resets automatically. A blue LED lights when AC pass-through is detected.
Rated power is 1800 W. The inverter carries 1801 to 2160 W for up to 1 minute and peaks of 2161 to 3600 W for up to 3 seconds, with a maximum surge current of 197 A, so motors and compressors get help at start-up.
It produces 120 VAC ±3% pure sine wave output with total harmonic distortion under 3% (12.5 V battery, resistive load) and a maximum efficiency of 91%.
No-load current is 2.0 A or less, and load sense mode drops that below 0.1 A. Load sense ships turned off. Enable it with the DIP switches, which select a 5 W or 45 W threshold and an optional 10-minute interval, or with a PowerTrak display, which sets the threshold from 5 to 45 W in 5 W steps.
The RV-C port links the inverter to a PowerTrak display (sold separately) that reports DC voltage, AC output volts, amps, watts and frequency, FET temperature and fault codes. A switch activates the built-in RV-C terminating resistor when the inverter is at the end of the network. Set the On/Off/Remote main switch to Remote to use the ASW-R remote or an external switch on the enable terminals.
Under-voltage shutdown defaults to 10.0 V and can be raised to as much as 11.5 V from a PowerTrak display, with recovery 2.5 V above the shutdown setting. The inverter warns at 11.0 V and protects against over-voltage above 16.5 V.
The DC input is protected against reverse polarity, over-current, over-voltage and under-voltage, with a red LED that lights for reversed battery cables. The AC output is protected against short circuit and overload, and the unit shuts down at a heatsink temperature above 95 °C (203 °F). Dry contact terminals can trigger an alarm or light on a fault.
Single 30 A RVs. Keep the microwave, TV and outlets on one panel that runs from shore power at the campground and from the battery off-grid.
Boats. Install it in a dry compartment between the shore power inlet and the AC distribution panel.
Go Power! lithium systems. Share one RV-C network with Go Power! Advanced Lithium Batteries, the Battery Manager Kit and Go Power! | Dometic MPPT solar controllers.
Both include the 30 A transfer switch and a 2-year warranty. The ASW-1200-12-TS is rated 1200 W with a 2400 W surge for lighter van and small-trailer loads. The ASW-1800-12-TS adds 600 W of output and a 3600 W surge for loads such as a 1000 W microwave.
The AIC-2000-12-SL is an inverter charger rated 2000 W with a 4000 W surge, a 30 A transfer switch and a 100 A battery charger, with a 3-year warranty. The ASW-1800-12-TS has no charger, so it suits RVs that already have a converter or charger.
Connect a 12 V battery bank only. Go Power estimates about 170 A of draw at full load and suggests at least 200Ah of lithium for sustained use, or twice that in lead-acid. The manual specifies #2 AWG copper rated 105 °C, each cable under 10 ft (3 m), a 200 A Class T fuse or breaker within 18 in (45 cm) of the battery, and a disconnect switch if you use a fuse. On the AC side it calls for 10 AWG copper rated 90 °C on a 30 A breaker, branch-rated breakers in your panel, and pass-through current no higher than 30 A.
Install it indoors or in a dry compartment on a noncombustible surface, flat (base down or up) or on a wall in a horizontal position, never vertical, with 4 in (100 mm) of open space around the vents. A neutral grounding screw controls whether the AC output neutral is bonded to ground and should be set by qualified personnel to match code. Go Power recommends a certified RV technician or licensed electrician.
It picks the power source for you. With shore or generator power present, the inverter passes it through (up to 30 A) and stays idle. When that AC drops, it switches to the inverter in 20 ms or less.
Go Power says any single appliance up to 1800 W, one high-draw item at a time, but not a rooftop air conditioner without a soft-start. From one Go Power! 100Ah Advanced Lithium battery (about 1,280 Wh at 90% inverter efficiency), it estimates about 45 minutes for a 1500 W induction burner and 1 hour for a 1000 W microwave.
No. Go Power suggests keeping your converter or adding a separate charger.
The Go Power! 1800 Watt Advanced Sine Wave Inverter pairs 1800 watts of pure sine power with a built-in 30 A transfer switch, PowerTrak connectivity and UL 458 listing, so your coach runs the same on shore power or battery. If you'd like help planning the wiring for your RV, the Outbound Power team is happy to help.
