The Go Power! 3000 Watt 24 Volt Industrial Pure Sine Wave Inverter (model GP-ISW3000-24) converts 24 volt DC battery power into pure sine wave AC. It delivers 3,000 watts continuously and a 6,000 watt surge through a hardwire AC output, so it connects to your AC wiring or panel rather than taking plug-in cords.
Go Power says it can run any tool or appliance within its wattage range, including multiple appliances, TVs, stereos and computers, and suggests it as a source of emergency backup power. Its model chart lists it for large 24 volt loads. It's certified to UL 458 and carries a 2-year Go Power warranty.
The AC end has a hardwire terminal under a cover plate with a cable clamp. For 100 to 120 VAC output, the manual specifies #8 AWG line and neutral wires up to 16 feet and a #8 to #10 ground wire up to 32 feet, with all wiring rated 75 °C or higher.
The inverter holds 3,000 watts continuously, up to 115% (3,450 VA) for one minute and a 6,000 watt surge for one second. That headroom helps motors and compressors start. A short circuit on the output shuts it down within one second.
Harmonic distortion stays under 5% at normal load, so appliances and electronics get a smooth waveform like utility power. Front-panel DIP switches select 100, 110, 115 or 120 VAC and 50 or 60 Hz. Maximum efficiency for the 24 volt model is 91%.
Idle draw is 2.0 A or less with no load. Turn on Powersave with DIP switch 4 and it drops below 0.2 A until a load appears, with a front-panel dial to set the wake-up threshold. Loads take about one second to start. The manual says that's fine for steady loads like TVs and stereos but may not suit bread makers, power tools or blenders.
Three LEDs report input voltage, output load and fault status, and a 6-port green terminal includes dry relay contacts for an alarm or indicator light. Protection covers input over-voltage, under-voltage and reverse polarity with an internal fuse, plus output short circuits, overloads and heat sink over- or under-temperature. The inverter alarms and shuts down at 21 V, restarts at 25 V and shuts down above 33 V. A temperature and load-controlled fan manages heat.
Set the power switch to REMOTE and add Go Power's ISW Inverter Remote for 24V ISW inverters (GP-ISW-R-24). Go Power says it gives you on/off, a battery-voltage and output bar graph and fault indicators on a 25 foot cable. The GP-SWR-A push on/off remote with an LED is also listed for this model.
24 volt fleet and work trucks. Feed the truck's AC circuits so tools and appliances share up to 3,000 watts.
24 volt boats. Supply AC branch circuits from the house bank, with the inverter in a dry compartment.
Emergency backup. Run appliances and electronics from a charged 24 volt bank when other power is out.
Go Power calls modified sine power a stepped approximation that's fine for tools, lights and resistive loads but can buzz, run hot or damage sensitive electronics and some chargers. The GP-ISW3000-24 delivers pure sine power.
Go Power's model chart lists the GP-ISW2000-24 at 2,000 watts continuous and 3,500 watts surge with two GFCI outlets, in a 17.45 x 9.76 x 3.27 inch case. The GP-ISW3000-24 adds 1,000 watts and a hardwire output in a 17.40 x 10.04 x 6.22 inch, 18.08 lb case.
Both share the 3,000 watt and 6,000 watt ratings in the same case. The 12 volt model runs on 10.5 to 16.5 VDC with 90% maximum efficiency and needs #4/0 AWG cable. This 24 volt model runs on 21 to 33 VDC and needs #2 AWG. The voltage isn't switchable, so match the model to your bank.
Go Power estimates this inverter draws about 139 A from a 24 V battery at full load, and that a 100 Ah 24 V lithium bank runs it flat-out for roughly 41 minutes. The manual lists #2 AWG copper cable and a 300 A inline fuse or circuit breaker for this model, with a combined cable length of no more than 10 feet (3 m) and the fuse ideally within 18 inches of the battery. DC overcurrent protection isn't included, and a battery disconnect switch is required unless a circuit breaker fills that role. Go Power's spec sheet pairs the 24 volt model with the GP-DC-KIT3 install kit, and Go Power advises keeping the DC run short.
The manual calls for GFCI protection on the branch circuits fed by the AC output and lists GFCI models Go Power has tested. Never connect the AC output to shore power or a generator; the manual warns that severe damage may occur and won't be covered by the warranty. Mount the inverter indoors or in a dry compartment with air between -4 °F and 104 °F (-20 °C and 40 °C), at least 4 inches of clearance around the vents and the case horizontal, never vertical. Go Power recommends professional installation, and the manual states the inverter isn't intended for life support or other medical equipment.
Anything whose running watts stay under 3,000 and whose start-up surge stays under 6,000 watts. Go Power mentions a microwave, coffee maker and electronics running at once.
No. It has a hardwire AC output terminal that connects to your AC wiring.
Yes, the GP-ISW3000-12. This page is the 24 volt model, so check your battery voltage before you order.
Go Power warrants the GP-ISW3000-24 for two years against defects in materials and workmanship. The manual says opening or altering the unit voids the warranty.
The Go Power! 3000 Watt 24 Volt Industrial Pure Sine Wave Inverter brings 3,000 watts of pure sine power and a 6,000 watt surge to your 24 volt battery bank through a hardwire output, with UL 458 certification. If you'd like help planning the cables, fuse or AC connection, the Outbound Power team is happy to help.
