PRODUCT DETAILS
Our largest pure sine wave inverter, the Go Power! GP-ISW3000 is the ultimate choice for large loads that demand an exact replica of AC power. The GP-ISW3000 can run any tool or appliance within its wattage range. The GP-ISW3000 is the professionals choice for clean reliable power when you need it.
Ideal for powering multiple appliances, electronic equipment like TVs, stereos, computers, or as a source of emergency backup power, the Go Power! GP-ISW3000 is suitable for a range of applications. This inverter is included in our largest solar system, the SOLAR EXTREME, which features three solar panels, a converter charger, transfer switch and all mounting hardware required to install on any RV or long-haul truck.
For a proper install, pair this inverter with an Install Kit and a Remote.
FEATURES
WHAT IT RUNS
Size by the continuous rating and leave headroom for start-up surges. Typical draws: phone/laptop 20–90 W, 32 in TV 50–80 W, CPAP 30–60 W, blender 300–600 W, coffee maker 600–1,000 W, microwave 700–1,200 W (1,000–1,700 W input), hair dryer 1,200–1,800 W. A 3,000 W inverter draws about 139 A from a 24 V battery at full load, so a 100 Ah 24 V lithium bank runs it flat-out for roughly 41 minutes.

FAQ
What can a 3,000-watt inverter run?
Anything whose running watts stay under 3,000 W and whose start-up surge stays under the surge rating. Multiple appliances at once — microwave, coffee maker and electronics — within the 3,000 W total.
Pure sine wave or modified sine wave?
Pure sine wave is the same clean power as a wall outlet and runs everything — TVs, laptops, CPAPs, induction cooktops, microwaves — quietly and at full efficiency. Modified sine wave is a stepped approximation that is fine for tools, lights and resistive loads but can buzz, run hot or damage sensitive electronics and some chargers. This model is pure sine wave.
Which install kit do I need?
At 24 V this inverter draws about 140 A full-load; use GP-DC-KIT3 (200 A, #2 AWG) or the 175 A breaker kit, and keep the DC run short.
How do I switch it on and off remotely?
Add the ISW Inverter Remote (25 ft cable). It gives you on/off, a battery-voltage and output bar graph and fault indicators where you live, and works with all GP-ISW inverters.
How big a battery do I need?
Figure amp-hours from watt-hours: a 3,000 W load for one hour uses about 130 Ah from a 24 V bank. Lithium can be drawn to near empty; AGM should stop around 50%. Keep the inverter within a few feet of the batteries and use the cable gauge from the install kit guide.
Is this a current model?
This is a previous-generation Go Power! inverter sold at outlet pricing while stock lasts. It carries the full 2-year warranty and North American support. The current series are the SSW (hardwire and outlet) and ASW (built-in transfer switch) inverters.
Is Go Power! the inverter installed in my RV from the factory?
Very likely, if your coach is a Jayco, Forest River, Thor or one of many other brands — Go Power! has supplied RV manufacturers since 1996, so these are the same products and the same support team your dealer uses.
What is the warranty?
Two years against defects in materials and workmanship, backed by Go Power!’s North American support team (part of Dometic).
